The present invention relates to a data recording medium,
a reading device for reading the data recording medium, a recording device for reading
the data recording medium and recording data to another medium, and methods thereof
for preventing forgery of paper money or securities.
In the related art, for example, the
international patent publication WO 00/34923
discloses a method for preventing forgery of sheet-like paper money or
securities by using built-in electronic circuits. In this method, an electronic
chip is put in a sheet-like bill or securities document, and the visible information
printed on the bill or securities document is encrypted and stored in the chip.
When using the bill or security, a forgery can be found by comparing the visible
information and the data stored in the chip, therefore preventing forgery. This
method has been attracting attention as an effective way of preventing forgery of
paper money or securities. This method was reported by the Nippon Keizai Shimbun
(Evening Edition, May 24, 2002). According to this method, by storing different
numbers in the built-in chips of different bills, it is possible to immediately
identify bills that do not have such built-in chips or those having false numbers
printed thereon.
Further, because this method makes it possible to pursue
the distribution channels of the bills used in crime-related transactions, and to
prevent money laundering, efforts are being made to put it into practical use.
However, in the above forgery prevention method, one has
to compare the visible information printed on the bill or securities document and
the data stored in the built-in electronic circuit chip. Usually, the visible information
is obtained by scanning the bill or securities document with a scanner, so depending
on performance of the scanner, the accuracy of reading the image of the visible
information on the bill or securities document changes greatly, consequently, it
becomes difficult to confirm whether the visible information is identical to the
data stored in the electronic circuit chip.
WO 02/02350
discloses antifalsification paper comprising a multilayered security element
having at least one visually verifiable optical effect and at least one integrated
circuit.
JP 07 274027
discloses a system for judging if an original document is replaced during
plural times of scanning and preventing reading of data when the original is replaced.
EP 1 139 302
discloses a method of checking sheets for forgery based on comparing visible
information on the sheet with information stored in an electronic circuit chip that
is part of the sheet.
A more specific object of the present invention is to provide
a data recording medium, a reading device for reading the data recording medium,

is possible to control the operation of the writer 650 based on the recording permission
data on the data storage unit 220. If recording of the image data 215 is not permitted,
user identification information is written to the data storage unit 220 as evidence
of operation of the data recording medium 200 (the copy source). Therefore, this
makes it possible to prevent forgery of the data on the data recording medium 200,
and enables a later follow-up survey.
Fourth Embodiment
This embodiment relates to a recording device that reads
the image data 215 from the data recording medium 200 and records the image data
215 to other media.
FIG. 8 is a block diagram of a configuration of a recording
device 800 according to the fourth embodiment of the present invention.
The recording device 800 comprises a first reader 810,
a second reader 820, a determination unit 830, a recorder 840, a writer 850 and
a controller 860.
The first reader 810 is provided to read the image data
215. For example, the first reader 810 may be a scanner, or a digital camera, or
any other device capable of reading data from a medium.
The second reader 820 reads "recording permission data"
included in the control data, which indicates whether it is permitted to record
the image data to other media.
The determination unit 830 is connected to the second reader
820. Based on the recording permission data obtained by the second reader 820, the
determination unit 830 ascertains if recording the image data 215 to other media
is permitted.
The recorder 840 records the image data 215 obtained by
the first reader 810 to a not-illustrated medium other than the medium 210 in the
data recording medium 200. Here, the "other medium" may be a medium the same as
the medium 210 but in another data recording medium 200, or paper on which data
are to be recorded, for example, paper used in a copier when making a copy of the
data recording medium 200.
Below, the another data recording medium 200 including
the other medium is referred to as "copy destination", and the data recording medium
200 read by the first reader is referred to as "copy source". That is, the data
recording medium acting as the copy destination is identical to the data recording
medium 200 shown in FIG. 1; it has a medium, the "other medium" as mentioned above,
the same as the medium 210, and a data storage unit the same as the data storage
unit 220. To the medium of the copy destination, a copy of the copy source is to
be written.
The writer 850 writes user identification information to
the data storage medium of the copy destination. The "user identification information"
is data for identifying a user, such as time and date when the user makes copies,
makes printings, or reads data, locations, or user identification numbers.
The controller 860 includes a CPU (Central Processing Unit),
and is connected to the first reader 810, the determination unit 830, the recorder
840, and the writer 850. When the determination unit 830 ascertains that recording
of the image data to the other medium is not permitted, the controller 860 directs
the writer 850 to write the user identification information to the data storage
medium of the data recording medium acting as the copy destination.
Next, the operation of the recording device 800 is explained
below.
FIG. 9 is a flow chart showing the operation of the recording
device 800 of the fourth embodiment of the present invention.
Referring to FIG. 9, in step S910, the first reader 810
reads the image data 215 from the data recording medium 200.
In step S920, from the control data, the second reader
820 reads the recording permission data that indicates whether recording the image
data 215 to other media is permitted.
In step S930, based on the recording permission data, the
determination unit 830 ascertains if recording of the image data 215 to other media
is permitted. If it is not permitted to record the image data 215 to other media,
the routine proceeds to step S940, whereas if it is permitted to record the image
data 215 to other media, the routine proceeds to step S950.
In step S940, the controller 860 directs the writer 850
to write the user identification information to the data storage medium of the data
recording medium acting as the copy destination.
In step S950, the controller 860 directs the recorder 840
to record the image data 215 to the medium of the data recording medium acting as
the copy destination.
Further, programs can be created to execute the above steps,
and operation of the device of the present embodiment can be controlled by a computer
based on the programs.
In this way, when making a copy of the data recording medium
200, specifically, when the recorder 840 tries to records the image data 215 to
any other medium, according to the above recording device 800, it is possible to
control the operation of the writer 850 based on the recording permission data on
the data storage unit 220. If recording of the image data 215 is not permitted,
user identification information is written to the data storage medium of the data
recording medium acting as the copy destination as evidence of operation of the
data recording medium 200. Therefore, this makes it possible to prevent forgery
of the data on the data recording medium 200, and enables a later follow-up survey.
Fifth Embodiment
FIG. 10 is a view showing an overall configuration of a
duplicating apparatus according to the fifth embodiment of the present invention.
The duplicating apparatus shown in FIG. 10 includes a main
body 1 and an ADF (Auto Document Feeder) 3. On the upper side of the main body 1,
a contact glass 2a and a slit glass 2b smaller than the contact glass 2a are provided.
Note that the configuration shown in FIG. 10 is presented
just for illustration; the duplicating apparatus of the present embodiment is not
limited to this configuration; it may be a facsimile machine, a scanner, or an apparatus
combining all of them.
The ADF 3 is provided on the main body 1. With a hinge
mechanism, one end of the ADF 3 can be moved up and down freely to cover or make
the contact glass 2a open.
Next, the configuration of the main body 1 is explained.
FIG. 11 is a block diagram of a configuration of the duplicating
apparatus according to the fifth embodiment of the present invention.
As shown in FIG. 11, the main body 1 includes a first reader
20, a second reader 21, a moving unit 22, a recorder 23, a writer 24, a determination
unit 25, and a controller 26.
The first reader 20 reads the image data in the data recording
medium 200 as shown in FIG. 1. Detailed description of the data recording medium
200 is omitted here. The first reader 20 at least includes a light emitting source,
a reflective mirror, a condensing lens, and a CCD (Charge Coupled Device).
The second reader 21 is mounted integrally with the first
reader 20, and while the first reader 20 reads the image data, the second reader
21 reads "recording permission data" from the control data, which indicates whether
recording of the image data is permitted.
The moving unit 22 includes a driving roller 17a driven
by a not-illustrated driving device, a driven roller 17b, and a wire 18. The wire
18 is wound on the driving roller 17a and driven roller 17b, and the first reader
20 is fixed on the wire 18. The moving unit 22 moves the first reader 20 and the
second reader 21 under the contact glass 2a, acting as a supporting member, back
and forth along the directions indicated by the arrow 30. In FIG. 10, the length
of the arrow 30 indicates the region in which the first reader 20 and the second
reader 21 move.
The recorder 23 records the image data 215 read by the
first reader 20 from the data recording medium 200 to a not-illustrated medium of
another data recording medium 200.
Here, the another data recording medium 200 acts as a copy
destination, and the data recording medium 200 read by the first reader is thus
referred to as "copy source". That is, the data recording medium acting as the copy
destination is identical to the data recording medium 200 shown in FIG. 1; it has
a medium the same as the medium 210, and a data storage unit the same as the data
storage unit 220; to the medium of the copy destination, the image data 215 is to
be recorded to make a copy of the data recording medium 200 (copy source).
The writer 24 writes the control data to the data recording
medium that is the copy destination.
The determination unit 25, based on the recording permission
data obtained by the second reader 21, ascertains if recording the image data 215
is permitted.
The controller 26 includes a CPU (Central Processing Unit).
When the determination unit 25 ascertains that recording the image data to other
media is not permitted, the controller 25 directs the recorder 23 and the writer
24 not to write the image data and the control data, respectively, to the data recording
medium acting as the copy destination. While, when the determination unit 25 ascertains
that recording the image data to other media is permitted, the controller 25 directs
the recorder 23 and the writer 24 to write the image data and the control data,
respectively, to the copy destination.
Note that the first reader 20 and the second reader 21
may be attached to the main body 1 separately. For example, the second reader 21
may be mounted on the feeding path of the data recording medium extending from a
loading member 10 mentioned below to the first pair of paper delivery rollers 15
and the second pair of paper delivery rollers 16.
Next, the configuration of the ADF 3 is explained.
The ADF 3 includes a recording medium tray 4, a stopping
portion 5, a transportation portion 6, a delivery portion 7, and a delivery tray
8.
In the recording medium tray 4, a number of data recording
media 200 (indicated by a letter "P") are placed, and the data recording media 200
are separated into single pages by the separation portion 5. Certainly, not only
the data recording medium 200, but also any other medium without a data storage
unit 220 as shown in FIG. 1, such as a medium printed with letters or images, may
be placed in the recording medium tray 4.
The separation portion 5 includes a blocker 9, a loading
member 10, a feeding belt 11, and a separation roller 12.
The blocker 9 blocks the data recording media 200 in the
recording medium tray 4 from entering the separation unit 5, and aligns the ends
of the data recording media 200 when the data recording media bump their ends against
the blocker 9. By a not-illustrated blocking solenoid, the blocker 9 is movable
between a position where the blocker 9 may touch the ends of the data recording
media 200 and a position away from the data recording media 200.
The loading member 10 is also movable, by using a not-illustrated
loading solenoid, between a position where the loading member 10 may touch the data
recording media 200 and a position away from the data recording media 200. Being
driven by a feeding start signal from the main body 1, the loading solenoid moves
the loading member 10 close to the data recording media 200 to feed the upper most
data recording medium 200 to the separation unit 5. At this time, the blocking solenoid
is also driven and moves the blocker 9 away from the data recording media 200.
The feeding belt 11 is wound on the driving roller 11a
and the driven roller 11b. When separating the data recording media 200, by a not-illustrated
feeding motor, the driving roller 11a is driven to rotate clockwise, and thus the
feeding belt 11 is driven to rotate.
The separation roller 12 is in contact with the feeding
belt 11, and is driven by the feeding motor to rotate clockwise, thereby separating
the upper most data recording medium 200.
The transportation portion 6 includes a driving roller
13 and a driven roller 14 in contact with the driving roller 13. The transportation
portion 6 sandwiches the data recording medium 200 sent from the separation unit
5, and transports the data recording medium 200 to the slit glass 2b, the position
where the data recording medium 200 is read by the first reader 20 and the second
reader 21.
Inside the main body 1 and under the slit glass 2b, the
first reader 20 and the second reader 21 are held stationary, and read the image
data and the control data, respectively, at the same time from the data recording
medium 200 passing over the slit glass 2b.
The delivery portion 7 includes a pair of delivery rollers
15 and a pair of delivery rollers 16. The data recording medium 200 that has passed
over the slit glass 2b is sandwiched by the pair of delivery rollers 15, and the
pair of delivery rollers 16 as well, and delivered to the delivery tray 8.
When a data recording medium 200 is placed on the contact
glass 2a for reading, by moving the first reader 20 and the second reader 21 under
the contact glass 2a back and forth along the directions indicated by the arrow
30 in FIG. 10, the first reader 20 and the second reader 21 can also read the image
data and the control data, respectively, at the same time from the data recording
medium 200. Therefore, it is not necessary to mount the second reader 21 under the
contact glass 2a to cover the range of the data recording medium 200, and this allows
reading the control data with a lesser number of the second readers 21 and thus
lowering cost. Further, it is possible to reduce the amount of electromagnetic waves,
therefore reduce adverse influences on the human body.
Note that, although it is described above that the first
reader 20 and the second reader 21 are moved under the contact glass 2a back and
forth at the same time to read the image data and the control data from the data
recording medium 200, the present embodiment is not limited to this. For example,
the first reader 20 may read the image data after the second reader 21 reads the
control data. More specifically, first, the first reader 20 and the second reader
21 are moved under the contact glass 2a back and forth, and the second reader 21
reads the control data from the data recording medium 200; then the first reader
20 and the second reader 21 are moved under the contact glass 2a back and forth
again, and the first reader 20 reads the image data from the data recording medium
200.
When a data recording medium 200 is placed in the recording
medium tray 4 for reading the image data and the control data, the first reader
20 and the second reader 21 are held stationary under the slit glass 2b to read
the image data and the control data at the same time from the data recording medium
200 transported by the ADF 3.
Next, the operation of the duplicating apparatus of the
present embodiment is explained below with reference to following flow charts.
FIG. 12 through FIG. 17 are flow charts showing the operation
of the duplicating apparatus of the present embodiment.
Here, the case in which the first reader 20 and the second
reader 21 read the image data and the control data, respectively, at the same time,
and the case in which the first reader 20 reads the image data after the second
reader 21 reads the control data are explained separately; and flow charts in FIG.
13 through FIG. 17 illustrate the former case, and the flow chart in FIG. 12 illustrates
the latter case.
First, explanations are made of the case in which the first
reader 20 and the second reader 21 read the image data and the control data at the
same time from the data recording medium 200.
FIG. 13 and FIGs. 15 through 17 are flow charts showing
the duplication process of the duplicating apparatus of the present embodiment,
and FIG. 14 is a flow chart showing the determination process of the duplicating
apparatus of the present embodiment.
Here, the duplication process and the determination process
are performed in parallel. In addition, in FIG. 13 through 17, "F" is a status variable,
having three values of "undetermined", "permitted", and "rejected". For example,
the steps after step S1370 in the duplication process shown in FIG. 13 wait until
the value of the variable F for recording is determined in the determination process
mentioned below.
The determination process is explained below with reference
to FIG. 14.
In step S1410, the second reader 21 reads the control data
from the data storage unit 220 of the data recording medium 200.
In step S1420, depending on whether reading of the control
data is successful or not, the determination unit 25 confirms if the data storage
unit 220 is available. If the data storage unit 220 is available, the routine proceeds
to step S1430, whereas if the data storage unit 220 is not available (the data storage
unit 220 does not exist), the routine proceeds to step S1460.
In step S1430, the determination unit 25 analyzes the data
storage unit 220, that is, the control data in the data storage unit 220.
In step S1440, based on the recording permission data included
in the control data, the determination unit 25 confirms if recording the image data
to the destination data recording medium is permitted. If recording is permitted,
the routine proceeds to step S1460, whereas if recording is not permitted, the routine
proceeds to step S1450.
In step S1450, the status variable F is assigned a value
of "rejected".
In step S1460, the status variable F is assigned a value
of "permitted".
Next, the duplication process is explained below with reference
to FIG. 13 and FIGs. 15 through 17.
In the present embodiment, there are four kinds of duplication
processes. FIG. 13 illustrates the first one. In the duplication process shown in
FIG. 13, for example, in a duplicating apparatus able to output red, green, and
blue colors, when recording color images as the image data to a medium of a data
recording medium acting as a copy destination, if it is confirmed that recording
is permitted in the above determination process, the recorder 23 records the image
data to the medium of the copy destination, whereas if it is confirmed that recording
is not permitted in the above determination process, the recorder 23 records any
two colors among the red, green, and blue colors to the medium of the copy destination.
In step S1310, the status variable F is initialized by
assigning F a value of "undetermined".
In step S1320, the first reader 20 reads the image data
from the medium 210 of the data recording medium 200.
In step S1330, image processing for the image data is performed
in order to record the image data, for example, the image processing includes necessary
corrections to the image data, scaling-up or scaling-down of the image data.
In step S1340, the recorder 23 records the red color data
to a medium of a data recording medium acting as a copy destination.
In step S1350, the recorder 23 records the green color
data to the medium of the data recording medium acting as the copy destination.
In step S1360, the determination unit 25 ascertains if
the value of the status variable F is "undetermined". If the value of F is "undetermined",
the routine waits until F is assigned a value other than "undetermined". The routine
proceeds to step S1370 when F is assigned a value other than "undetermined".
In step S1370, the determination unit 25 ascertains if
the value of the status variable F is "permitted". If the value of F is "permitted",
the routine proceeds to step S1380. If the value of F is not "permitted", the routine
ends without the blue data being recorded to the medium of the data recording medium
acting as the copy destination, or the control data being recorded to the data storage
unit of the data recording medium acting as the copy destination.
In step S1380, the recorder 23 records the blue data to
the medium of the data recording medium acting as the copy destination, and at the
same time, the writer 24 writes the control data to the data storage unit of the
data recording medium acting as the copy destination.
Note that step S1360 and step S1370 may be performed at
any time after step S1310 and before step S1380.
FIG. 15 illustrates the second duplication process. In
the duplication process shown in FIG. 15, for example, if it is confirmed that recording
is permitted in step S1440 of the above determination process, the recorder 23 records
the image data, whereas, if it is confirmed that recording is not permitted in step
S1440 of the above determination process, the image size of the image data is changed
and then recorded to the medium of the data recording medium acting the copy destination.
In step S1510, the status variable F is initialized by
assigning F a value of "undetermined".
In step S1520, the first reader 20 reads the image data
from the medium 210 of the data recording medium 200.
In step S1530, image processing for the image data is performed
in order to record the image data, for example, the image processing includes necessary
corrections to the image data, scaling-up or scaling-down of the image data.
In step S1540, the determination unit 25 confirms if the
value of the status variable F is "undetermined". If the value of F is "undetermined",
the routine waits until F is assigned a value other than "undetermined". The routine
proceeds to step S1550 when F is assigned a value other than "undetermined".
In step S1550, the determination unit 25 ascertains if
the value of the status variable F is "permitted". If the value of F is not "permitted",
the routine proceeds to step S1560, otherwise the routine proceeds to step S1570.
In step S1560, the recorder 23 records image data obtained
by changing the image size of the image data serving as the image data to the medium
of the data recording medium acting as the copy destination, and then the routine
ends.
In step S1570, the recorder 23 records the original first
image data to the medium of the data recording medium acting as the copy destination,
while the writer 24 writes the control data to the data storage unit of the same
data recording medium, and then the routine ends.
FIG. 16 illustrates the third duplication process. In the
duplication process shown in FIG. 16, the image data and the control data are recorded
and written to the medium and the data storage unit of the data recording medium
acting the copy destination beforehand. If it is confirmed that recording is not
permitted in step S1440 of the above determination process, a warning message is
additionally recorded to the medium of the data recording medium in which the image
data and the control data are recorded or written.
In step S1610, the status variable F is initialized by
assigning F a value of "undetermined".
In step S1620, the first reader 20 reads the image data
from the medium 210 of the data recording medium 200.
In step S1630, image processing for the image data is performed
in order to record the image data, for example, the image processing includes necessary
corrections to the image data, scaling-up or scaling-down of the image data.
In step S1640, the recorder 23 records the image data to
the medium of the data recording medium acting as the copy destination, while the
writer 24 writes the control data to the data storage unit of the same data recording
medium.
In step S1650, the determination unit 25 confirms if the
value of the status variable F is "undetermined". If the value of F is "undetermined",
the routine waits until F is assigned a value other than "undetermined". The routine
proceeds to step S1660 when F is assigned a value other than "undetermined".
In step S1660, the determination unit 25 ascertains if
the value of the status variable F is "permitted". If the value of F is not "permitted",
the routine proceeds to step S1670, otherwise the routine proceeds to the end.
In the step S1670, the recorder 23 records a warning message
to the medium of the data recording medium acting as the copy destination in which
the first image data and the control data recorded or written.
FIG. 17 illustrates the fourth duplication process. In
the duplication process shown in FIG. 13, for example, in a duplicating apparatus
able to output cyan (simply abbreviated as "C"), magenta (abbreviated as "M"), yellow
(abbreviated as "Y"), and black (abbreviated as "B") colors, when recording color
images as the image data to a medium of a data recording medium acting as a copy
destination, if it is confirmed that recording is permitted in the above determination
process, the recorder 23 records the image data to the medium of the copy destination,
whereas if it is confirmed that recording is not permitted in the above determination
process, the recorder 23 records any three colors among cyan, magenta, yellow, and
black colors to the medium of the copy destination.
In step S1710, the status variable F is initialized by
assigning F a value of "undetermined".
In step S1720, the first reader 20 reads the image data
from the data recording medium 200.
In step S1730, image processing for the image data is performed
in order to record the image data, for example, the image processing includes necessary
corrections to the image data, scaling-up or scaling-down of the image data.
In step S1740, the recorder 23 records the yellow color
to the medium of the data recording medium acting as the copy destination.
In step S1750, the recorder 23 records the magenta color
to the medium of the same data recording medium.
In step S1760, the determination unit 25 ascertains if
the value of the status variable F is "undetermined". If the value of F is "undetermined",
the routine waits until F is assigned a value other than "undetermined".
The routine proceeds to step S1370 when F is assigned a
value other than "undetermined".
In step S1770, the determination unit 25 ascertains if
the value of the status variable F is "permitted".
If the value of F is "permitted", the routine proceeds
to step S1780.
If the value of F is not "permitted", the routine proceeds
to step S1790 without the cyan data being recorded to the medium of the destination
data recording medium, nor the control data being recorded to the data storage unit
of the destination data recording medium.
In step S1780, the recorder 23 records the cyan data to
the medium of the destination data recording medium, and at the same time, the writer
24 writes the control data to the data storage unit of the destination data recording
medium.
In step S1790, the recorder 23 records the black data to
the medium of the destination data recording medium.
Note that step S1760 and step S1770 may be performed at
any time after step S1710 and before step S1790.
Above, explanations are made of the case in which the first
reader 20 and the second reader 21 read the image data and the control data at the
same time. Next, an explanation is made of the case in which the first reader 20
reads the image data after the second reader 21 reads the control data.
FIG. 12 is a flow chart illustrating such a case.
In step S1210, the second reader 21 reads the control data
from the data recording medium 200.
In step S1220, depending on whether reading of the control
data is successful or not, the determination unit 25 confirms if the data storage
unit 220 is available. If the data storage unit 220 is available, the routine proceeds
to step S1230, whereas if the data storage unit 220 is not available (the data storage
unit 220 does not exist), the routine proceeds to step S1250.
In step S1230, the determination unit 25 analyzes the data
storage unit 220, that is, the determination unit 25 analyzes the control data in
the data storage unit 220.
In step S1240, based on the recording permission data included
in the control data, the determination unit 25 confirms whether recording the image
data to a destination data recording medium is permitted. If recording is permitted,
the routine proceeds to step S1250, whereas if recording is not permitted, the routine
ends.
In step S1250, the first reader 20 reads the image data
from the data recording medium 200.
In step S1260, image processing for the image data is performed
in order to record the image data, for example, the image processing includes necessary
corrections to the image data, scaling-up or scaling-down of the image data.
In step S1270, the recorder 23 records the image data to
a medium of a data recording medium acting as a copy destination, and at the same
time, the writer 24 writes the control data to the data storage unit of the same
data recording medium.
According to the duplicating apparatus of the present embodiment,
it is possible to control the operations of the recorder 23 and the writer 24 based
on the determination made by the determination unit 25, therefore, enabling prevention
of forgery of the data recording medium 200.
Sixth Embodiment
FIG. 18 is a block diagram of the configuration of an image
forming apparatus 1800 according to the sixth embodiment of the present invention.
The image forming apparatus 1800 may be a copier, a facsimile machine, a scanner,
or an apparatus combining all of them.
The image forming apparatus 1800 includes a first reader
1810, an information acquisition unit 1820, a writer 1830, a recorder 1840, a second
reader 1850, a determination unit 1860, and a controller 1870.
The image forming apparatus 1800 reads the image data and
the control data in the data recording medium 200 as shown in FIG. 1. In the present
embodiment, the medium 210 in the data recording medium 200 is a manuscript, thus
the data recording medium 200 includes the manuscript and a data storage unit 220.
The data storage unit 220 is a monolithic RFID chip. Further, images are recorded
on the manuscript 210, and control data are stored in the data storage unit 220.
For example, in the present embodiment, the recording permission data mentioned
above are stored in the data storage unit 220.
The first reader 1810 reads image data from the manuscript
210 of the data recording medium 200.
The information acquisition unit 1820 is adapted to acquire
information concerning image reading, for example, date and time information, or
device information, or user identification data, or position information.
Even though not shown in figures, the information acquisition
unit 1820 may include a date and time information generator, a device information

in the book 3200 so far. The user information may include various kinds of user
identification numbers.
The writer 2850 acquires information of reading images
of the book 3200 (image read information), and writes the acquired image read information
to the data storage unit 3210 of the book 3200. Here, for example, the image read
information is information of a user who is going to read images of the book 3200,
and may be various kinds of user identification numbers. For example, users are
required to input their passwords with a not-illustrated input device in order to
use the device, and the writer 2850 accepts the input user information from the
input device. Additionally, the image read information may further include data
of date and time and locations.
The recorder 2860 records the image data obtained by the
first reader 2810 to a destination recording medium. The destination recording medium,
for example, is paper of a book.
The determination unit 2830 determines if the read history
information is obtained by the second reader 2820, in other words, the determination
unit 2830 determines if the user information is included in the read history information
obtained by the second reader 2820. In addition, the determination unit 2630 determines
if the user information obtained by the second reader 2820 is consistent with the
user information acquired by the writer 2850.
The controller 2840 includes a CPU (Central Processing
Unit), and controls the first reader 2810, the writer 2850 and the recorder 2860
according to the determination made by the determination unit 2830.
If the determination unit 2830 confirms that the read history
information is not obtained by the second reader 2820, the controller 2840 directs
the writer 2850 to write the image read information to the data storage unit 3210
of the book 3200.
Further, if the determination unit 2830 determines that
the user information obtained by the second reader 2820 is consistent with the user
information acquired by the writer 2850, the controller 2840 directs the first reader
2810 to read the image data from the book 3200. Note that the controller 2840 need
not be integral with the image forming apparatus 2800; a usual PC (Personal Computer)
may be used as the controller 2840 in connection with the image forming apparatus
2800.
Next, the operation of the image forming apparatus 2800
of the present embodiment is explained below.
FIG. 29 is a flow chart showing the operation of the image
forming apparatus 2800 of the present embodiment.
In step S2910, the second reader 2820 reads control data
from the data storage unit 3210 in the book 3200. For example, the control data
includes read history information, that is, information of users who have read the
images of the book 3200 so far.
In step S2920, the determination unit 2830 determines if
the read history information is obtained by the second reader 2620, in other words,
the determination unit 2830 determines if the user information is included in the
read history information obtained by the second reader 2820. If the determination
unit 2830 confirms that the user information is obtained by the second reader 2620,
the routine proceeds to step S2930, whereas if the determination unit 2830 confirms
that the user information is not obtained by the second reader 2820, the routine
proceeds to step S2940.
In step S2930, the determination unit 2830 determines if
the user information obtained by the second reader 2820 is consistent with the user
information acquired by the writer 2850. If the determination unit 2830 determines
that the user information obtained by the second reader 2820 is consistent with
the user information acquired by the writer 2850, the routine proceeds to step S2950,
while if the determination unit 2830 determines that the user information obtained
by the second reader 2820 is not consistent with the user information acquired by
the writer 2850, the routine ends.
In step S2940, the controller 2840 directs the writer 2850
to write the acquired image read information to the data storage unit 3210 of the
book 3200.
In step S2950, the controller 2840 directs the first reader
2810 to read the image data from the book 3200.
In step S2960, the controller 2840 directs the recorder
2860 to record the image data obtained by the first reader 2810 to the destination
recording medium.
According to the image forming apparatus 2800 of the present
embodiment, while the images of the book 3200 can be digitized, if the read history
information is not included in the data storage unit 3210, it is possible to write
user information to the data storage unit 3210. As a result, when the digitized
images are misused, it is possible to uniquely identify a user who committed the
misuse, thereby enabling pursuit of the misuse.
12th Embodiment
FIG. 30 is a block diagram of the configuration of an image
forming apparatus 3000 according to the 12th embodiment of the present invention.
The image forming apparatus 3000 includes a first reader
3010, a second reader 3020, a determination unit 3030, a controller 3040, a writer
3050, a transmission unit 3060, and a recorder 3070.
The first reader 3010, for example, is a scanner, and reads
image data from the book 3200.
The second reader 3020 reads copyright information of the
book 3200 stored beforehand in the data storage unit 3210 in the book 3200. For
example, copyright information includes data indicating if the book 3200 is a copyrighted
work, that is, if the book 3200 is protected by copyright, and if it is, data indicating
if the copyright is in effect, that is, if it is in the protected period of the
copyright.
The writer 3050 acquires information of reading images
in the book 3200 (image read information), and writes the acquired image read information
to the data storage unit 3210 of the book 3200. Here, for example, the image read
information is information of a device that is to read images of the book 3200.
Specifically, the image read information may be the MAC ((Media Access Address))
of a PC (Personal Computer) that controls the device. Additionally, the image read
information may further include user data, date and time, and locations.
The transmission unit 3060 is connected to a not-illustrated
communication line, thus is able to communicate with peripheral devices. The transmission
unit 3060 transmits the copyright data obtained by the first reader 3010 and the
image read information obtained by the writer 3050 to a specified website cf a peripheral
device.
The determination unit 3030 determines if the reading (or
recording) of images of the book 3200 is permitted based on the copyright information
of the book 3200 obtained by the second reader 3020. In other words, the determination
unit 3030 determines if the book 3200 is a copyrighted work based on the copyright
information. If the determination unit 3030 determines that the book 3200 is a copyrighted
work, then the determination unit 3030 determines if the copyright is in effect,
that is, if it is in the protected period of the copyright. If the determination
unit 3030 determines that it is in the protected period of the copyright, reading
or recording of the book 3200 is not permitted.
Further, the determination unit 3030 determines if the
book 3200 has a data storage unit 3210.
In addition, the determination unit 3030 confirms if communication
between the transmission unit 3060 and the peripheral devices is possible. For example,
the determination unit 3030 confirms the connection condition between them using
PING or other methods. Here, the "PING" is a standard tool (command) included in
an OS (Operation System) of a computer system to confirm the connection condition
between the computer and a host through a network; when the PING command is executed,
IP packets are delivered to the host, and it is confirmed if the packets are correctly
transmitted to the host and a correct reply is received by the computer.
The recorder 3070 records the image data obtained by the
first reader 3010 to a destination recording medium. The destination recording medium,
for example, is paper of a book.
The controller 3040 includes a CPU (Central Processing
Unit), and controls the writer 3050 and the recorder 3070 according to the determination
made by the determination unit 3030.
If the determination unit 3030 determines that the copyright
of the book 3200 is in effect, and communication between the transmission unit 3060
and the peripheral devices is possible, the controller 3040 directs the transmission
unit 3060 to transmit the copyright information obtained by the second reader 3020
and the image read information acquired by the writer 3050 to the peripheral devices.
If the determination unit 3030 determines that the copyright
of the book 3200 is in effect, but communication between the transmission unit 3060
and the peripheral devices is not possible, the controller 3040 directs the writer
3050 to write the image read information, for example, device information acquired
by the writer 3050 to the data storage unit 3210.
If the determination unit 3030 determines that the copyright
of the book 3200 is not in effect, the controller 3040 directs the first reader
3010 to read the images of the book 3200, or the controller 3040 directs the recorder
3070 to record the images of the book 3200 to a destination medium.
If the determination unit 3030 determines that the book
3200 does not has a data storage unit 3210, the controller 3040 directs the first
reader 3010 to read the images of the book 3200, or the controller 3040 directs
the recorder 3070 to record the images of the book 3200 to a destination medium.
Note that the controller 3040 need not be integral with
the image forming apparatus 3000; a usual PC (Personal Computer) may be used as
the controller 3040 in connection with the image forming apparatus 3000.
Next, the operation of the image forming apparatus 3000
of the present embodiment is explained below.
FIG. 31 is a flow chart showing the operation of the image
forming apparatus 3000 of the present embodiment.
In step S3110, the determination unit 3030 determines if
the book 3200 has a data storage unit 3210. If the data storage unit 3210 exists,
the routine proceeds to step S3120, whereas if the data storage unit 3210 does not
exist, the routine proceeds to step S3150.
In step S3120, the second reader 3020 reads the copyright
data from the data storage unit 3210 in the book 3200.
In step S3130, if the determination unit 3030 determines
that the book 3200 is a copyrighted work within the protected period of the copyright,
that is, the copyright of the book 3200 is in effect, the routine proceeds to step
S3140.
If the determination unit 3030 determines that the book
3200 is not a copyrighted work, or is a copyrighted work beyond the protected period,
so the copyright of the book 3200 is not in effect, the routine proceeds to step
S3150.
In step S3140, if the determination unit 3030 determines
that communication between the transmission unit 3060 and the peripheral devices
is possible, the routine proceeds to step S3170, whereas if the determination unit
3030 determines that communication between the transmission unit 3060 and the peripheral
devices is not possible, the routine proceeds to step S3180.
In step S3150, the controller 3040 directs the first reader
3010 to read the image data from the book 3200.
In step S3160, the controller 3040 directs the recorder
3060 to record the image data obtained by the first reader 3010 to the destination
recording medium.
In step S3170, the controller 3040 directs the transmission
unit 3060 to transmit the copyright information and the image read information to
the peripheral devices.
In step S3180, the controller 3040 directs the writer 3050
to write the image read information to the data storage unit 3210 of the book 3200.
Note that in the image forming apparatus 3000 of the present
embodiment, the step of S3150 may be performed at any time after the start of the
routine before the step of S3130, and in this case, before the determination unit
3030 determines whether the copyright of the book 3200 is in effect, the controller
3040 may direct the first reader 3010 to read the images of the book 3200 in advance,
and may control the recorder 3070 based on the copyright data.
According to the image forming apparatus 3000 of the present
embodiment, it is possible to restrict illegal reading or copying of images of the
book 3200. Further, in case communication with the peripheral devices cannot be
made due to disconnection of the network, since it is possible to write device information
to the data storage unit 3210 attached to the book 3200, when the book 3200 is read
or copied someday by a device that is able to communicate with the peripheral devices,
it is possible to send the device information written in the data storage unit 3210
to a specified website to report the information of the device that committed illegal
reading or copying. In addition, if the image forming apparatus 3000 is able to
communicate with the peripheral devices, it is possible to send the copyright information
and device information to the specified website so as to report the information
of the device that committed illegal reading or copying.
In addition, programs can be created to execute the operations
of the image forming devices described in the ninth through 12th embodiments, and
therefore, the operations of the devices of the above embodiments can be controlled
by computers based on the programs.
While the present invention has been described with reference
to specific embodiments chosen for purpose of illustration, it should be apparent
that the invention is not limited to these embodiments, but numerous modifications
could be made thereto by those skilled in the art without departing from the basic
concept and scope of the invention.
Summarizing the effect of the invention, according to the
present invention, when the first reading unit reads the image printed on the data
recording medium, based on the determination made by the determination unit, it
is possible to control read operations of the first reading unit, thereby preventing
forgery of the data recording medium.
Further, if the determination unit determines that reading
of the image is not permitted, read operations of the first reading unit can be
stopped, preventing forgery of the data recording medium.
Further, by making the second reading unit movable, it
is not necessary to require the second reading unit to cover the entire range of
the data recording medium, and therefore it is possible to read the control data
with a lesser number of the second reading units, resulting in lower cost. Further,
it is also possible to reduce the amount of electromagnetic waves, and hence reduce
adverse influences on the human body.
Further, since it is possible to control the operations
of the recording unit and the writing unit based on the determination made by the
determination unit, forgery of the data recording medium is preventable.
In addition, when recording of the image is not permitted,
if the recording unit tries to record the image to another medium (a so-called target
medium), a warning message or other data different from the image is recorded to
the target medium, and therefore, forgery of the data recording medium is preventable.
Further, when recording of the image is not permitted,
user identification information can be written on the data storage unit of the source
data recording medium or on the target medium. This information can be used as evidence
of using the data recording medium, allowing prevention of forgery of the data recording
medium, and a later follow-up survey as well.
In addition, date and time, device information, position
information of the device, and user information related to read operations of the
image can be written on the data storage unit, and this enables a later follow-up
survey and prevention of forgery of the data recording medium as well.
Further, since communication with other devices is enabled,
it is possible to report to others when forgery is found.
Further, based on the number of times of read operations
already performed and the limit to the number of times of read operations, it is
possible to restrict the number of times of read operations, and to prevent illegal
copying.
Further, since it is possible to write device information
to the data storage unit when necessary, when misuse of images occurs, it is possible
to uniquely identify the device that committed the illegal act, thereby enabling
pursuit of the device.
In addition, when image reading is not permitted, it is
possible to control the first reading unit not to read, thus restricting illegal
reading or copying.
Further, it is possible to send copyright information or
device information to a specified website of a peripheral device so as to report
the information of the device that committed illegal reading or copying.
