Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of a security document management apparatus and method according to the present invention. However, terms to be described below are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

1 is a block diagram of an embodiment for explaining a security document management apparatus according to the present invention, which includes a location information input unit 110, a location information insertion unit 120, and an image forming unit 130. The image forming unit 130 may include an exposure unit 132, a developing unit 134, and a fixing unit 136.

More specifically, Figure 1 is a detailed block diagram of a security document production apparatus for producing a security document managed by the security document management apparatus according to the present invention. Here, IN 1 means given print data.

In the host device and the image forming apparatus connected to the network, the image forming apparatus may receive print data IN 1 from the host device and print out the received print data IN 1. At this time, the printed output is present as a document.

The image forming apparatus may be a printing apparatus such as a printer or a multifunction peripheral (MFP) having a printing function. The location information input unit 110, the location information insertion unit 120, and the image forming unit 130 may be provided in such an image forming apparatus.

The location information input unit 110 inputs location information to the location information insertion unit 120.

The security document managed by the security document management apparatus according to the present invention contains the input location information. The location information may include at least one of location information of a place where print data IN 1 is generated and location information of a place where print output is performed.

The location information of the place where the print data IN 1 is generated may be the location information of the above-described host device. Hereinafter, the place where the print data IN 1 is generated may be called a target device.

In addition, the position information of the place where the printout is performed may be the position information of the image forming apparatus described above. Hereinafter, a place where printing output is performed may be called a target forming apparatus.

On the other hand, the inputted position information is the position information of the place designated in advance corresponding to the place where the print data IN 1 is generated (hereinafter referred to as "first designated information") and the place designated in advance corresponding to the place where the printout is performed. At least one of the location information (hereinafter referred to as "second designation information").

For example, the target device was a host device of one of a plurality of host devices provided on the third floor of Building A, and the host devices were placed on the network (WWW: World Wide Web) and all the host devices provided in Building B and Building C. Suppose you are connected. At this time, it is assumed that the company residing in Building A is a subsidiary of the company residing in Building B and is a competitor of the company residing in Building C.

In this case, the first designated information may be location information of the target device (hereinafter referred to as "a information"), or may be location information of any host device (hereinafter referred to as "b information") provided on the fourth floor of Building A. In addition, the location information (hereinafter referred to as "c information") of all the host devices provided on the third and fourth floors of the building A may be composed of a information and c information.

In order for the location information input unit 110 to input location information including not only a information but also location information of another host device, a predetermined host device must be designated in advance for each target device. For example, in order to include not only a information but b information in the location information input by the location information input unit 110, when the target device is a host device provided on the third floor of the building A, the target device is located on the fourth floor of the building A with respect to the target device. The prepared host device must be designated in advance.

Similarly, if any host device provided in the building B is designated for the target device when the target device is provided in the building A, the location information input unit 110 indicates that the place where the print data IN 1 is generated is the building B. Location information containing location information of all host devices existing in a building can be input.

As a result, if not only the place where the print data IN 1 is generated but also other places is previously designated corresponding to the place where the print data IN 1 is generated, the location information input unit 110 generates a place where the print data IN 1 is generated. The location information including the location information and the location information of the other place can be input to the location information insertion unit 120.

All of the matters described above with respect to the first designated information may be applied in the same logic to the second designated information. As a result, if not only the place where the printout is performed but other places are also designated in advance corresponding to the place where the printout is performed, the location information input unit 110 determines the location information of the place where the printout was performed and the other place. Position information including the position information of the can be input to the position information inserting unit 120.

The location information of the host device and / or the image forming apparatus may be information about an IP address of the host device and / or the image forming apparatus. However, since the IP address can be easily changed, the location information of the host device and / or the image forming apparatus is more preferably information about a MAC address.

The location information input unit 110 may input the given location information or the acquired location information into the location information insertion unit 120. That is, the location information input unit 110 receives location information from the outside, and inputs the received location information to the location information insertion unit 120 to transmit the location information. As a result, the location information input unit 110 functions as a kind of buffer.

Here, the given location information refers to the location information directly input by the location information input unit 110 from the user. The location information input unit 110 inputs the received location information to the location information insertion unit 120. In this case, the user may input the location information of the target device or the location information of the target forming apparatus to the location information input unit 110, or may input the location information irrelevant to the target device or the target forming apparatus.

If the user wants to input the location information of the target device or the target forming apparatus to the location information input unit 110, the user, as shown in Figure 5, the network of the target device or the target forming apparatus (WWW: World Wide The location information on the web may be searched through the Internet 288, and the search result may be input to the location information input unit 110.

Meanwhile, the acquired location information refers to location information obtained from the outside by the location information input unit 110 without receiving an input from the user. To this end, the secure document management apparatus according to the present invention, as shown in Figure 5, preferably provided with a location information generating unit (not shown).

The location information generator (not shown) generates location information of the target device or the target forming apparatus. The location information generator (not shown) may be provided in the satellite 280 or the mobile phone base station 286.

For example, the location information generator (not shown) provided in the satellite 280 (GPS satellite) accurately recognizes a location on the earth of the target device or the target forming apparatus, and generates information about the recognized location. On the other hand, the GPS receiver is preferably mounted on the target device or the target forming apparatus. The mounted GPS receiver functions as a location information input unit 110 that receives information about the generated location as the location information from the satellite 280 and inputs the received location information to the location information insertion unit 120. In this case, the mounted GPS receiver may receive the information about the generated position directly from the satellite 280, and the antenna 282 connected with the target device or the target forming apparatus receives from the satellite 280. Information about the generated location may be received from the antenna 282.

Similarly, the location information generator (not shown) provided in the cell phone antenna 286 accurately recognizes the location of the target device or the target forming apparatus in the base station network and generates information on the recognized location. do. The base station network is composed of a plurality of cells, the cell phone base station provided for each cell has its own unique cell ID (Cell ID). As a result, the location information generator (not shown) provided in the cellular phone base station 286 existing in the cell where the target device or the target forming apparatus is located generates its own cell ID as the location information of the target device or the target forming apparatus. The location information input unit 110 provided in the target device or the target forming apparatus receives the generated location information, and inputs the received location information into the location information insertion unit 120.

On the other hand, even if the location information generating unit (not shown) provided in the satellite 280 or the mobile phone base station 286 generated the location information of only the target device or the target forming apparatus, the location information input unit 110 may generate the location information. In addition, location information including location information of another host peripheral device or another image forming apparatus may be input to the location information inserting unit 120. To this end, as described above, it is preferable that a different host device is correspondingly designated for each target device. Similarly, it is preferable that different image forming apparatuses be correspondingly designated for each target forming apparatus.

For example, the position information of a place previously designated corresponding to the place where the print data IN 1 was generated (hereinafter referred to as "extended position information") is the position information of the place where the print data IN 1 was generated (hereinafter referred to as "initial position information"). If the extended location information and the initial location information are stored in a database in advance, the location information generated by the location information generating unit (not shown) may be the initial location information. The information input unit 110 may input the extended position information into the position information insertion unit 120. Meanwhile, the extended location information may or may not include initial location information.

The position information inserting unit 120 inserts the received position information into the given print data IN 1. At this time, the location information inserting unit 120 is watermarked (watermarking) is preferably inserted into the print data IN 1. Watermarking is a copy protection technology proposed to prevent illegal copying. It is used not only to prevent illegal copying of various copyrighted contents, but also to prevent illegal copying of digital contents.

In this case, the location information inserter 120 may use various watermarking techniques, such as a Least Significant Bit (LSB) modulation technique. On the other hand, it is preferable that the print data IN 1 is not damaged by the inserted position information.

The image forming unit 130 prints the print data IN 1 having the position information inserted therein on the print medium. Here, the print medium is a comprehensive concept including not only paper but also an OHP film, and the image forming unit 130 outputs a tangible document. OUT 1 means the printed document. In the present invention, this document may be referred to as a security document.

If the position information is watermarked in the position information insertion unit 120 and inserted into the print data IN 1, the position information cannot be visually confirmed on the document OUT 1. Therefore, even those who attempt to leak the security document to the outside secretly do not recognize that the location information is inserted in the security document.

As such, if the location information has been watermarked and inserted, the location information can exist in both the portion representing the print data and the margin portion on the secure document. Thus, even if a part of the security document is torn or scratched and damaged, the security document still has location information.

The image forming unit 130 may include an exposure unit 132, a developing unit 134, and a fixing unit 136. At this time, the exposure unit 132 forms an electrostatic latent image by exposing the laser beam to the photosensitive medium that is already provided, according to the print data into which the position information is inserted, and the developing unit 134 develops the electrostatic latent image formed therein. The latent image is generated, and the fixing unit 136 fixes the generated developing latent image on a print medium to output the print data IN 1 into which the position information is inserted as a document.

Figure 2 is a block diagram of another embodiment for explaining the security document management apparatus according to the present invention, the location information extraction unit 210, location information acquisition unit 220, location information guessing unit 230, location information storage unit 240, an inspection unit 250, a replication unit 260, and a user interface unit 270.

Here, the copy unit 260 includes a copy information recording unit 262, an output image generating unit 264, an image forming apparatus unit 265, and a printing unit 268. The replica unit 260 may be implemented as a laser beam printer (LBP), an ink jet printer, or a latent heat printer.

Preferably, the location information extracting unit 210 to the user interface unit 270 are provided in the image forming apparatus. In particular, it is preferable to be provided in a copier, a scanner, or a multifunction machine. At this time, the multifunction device is preferably a multifunction device having a copying function or a scanning function. After all, since the common functions of the copier, scanner, and multifunction machine are to duplicate the information contained in a given document, such an image forming apparatus can be hereinafter referred to as an information replicating apparatus.

IN 2 refers to a document given to the information replication apparatus, that is, a document given to the location information extracting unit 210. More specifically, IN 2 refers to a document to be reproduced, and may or may not be a secure document. Hereinafter, documents other than security documents will be referred to as general documents.

If the general document is given to the information replication apparatus, the information replication apparatus may or may not duplicate the information contained in the general document. However, if a security document is given to the information replication apparatus, the information replication apparatus does not duplicate the information of the given security document if it determines that its location information is the location information of a place where the information contained in the security document cannot be duplicated. The security document management method according to the present invention will be described in more detail below.

The location information extraction unit 210 reads a given document IN 2 and extracts location information contained in the document. Here, if the general document is given as IN 2, the location information extraction unit 210 cannot extract the location information, and only if the document containing the location information, that is, the security document is given as IN 2, the location information extraction unit 210 Can extract location information.

That is, IN 2 may be a security document OUT 1 or a general document, but for convenience of explanation, it is assumed that the security document OUT 1 is hereinafter. The location information extracting unit 210 preferably scans a given document IN 2 to read the document.

At this time, it is preferable that the read position information is the position information of the place previously designated corresponding to the place where the document was produced. Here, the place where the document is produced means the place where the print data IN 1 contained in the document is generated. That is, the read position information may include initial position information or may include extended position information having initial position information.

The location information acquisition unit 220 acquires its location information. That is, the location information acquisition unit 220 obtains the location information of the information replication apparatus provided therein. At this time, the location information acquisition unit 220 itself obtains location information from the outside without input from the user.

To this end, the above-described location information generator (not shown) may also generate location information of the information replication apparatus. As already described above, the location information generator (not shown) may be provided in the satellite or mobile phone base station.

For example, the position information generator (not shown) provided in the GPS satellite accurately recognizes the position on the earth of the information replication apparatus, and generates information about the recognized position. On the other hand, the information replication device is preferably equipped with a GPS receiver. The mounted GPS receiver functions as the location information acquisition unit 220 by acquiring the information on the generated location as the location information from the satellite.

Similarly, the location information generation unit (not shown) provided in the cell phone antenna accurately recognizes the location of the information replication apparatus in the base station network, and generates information on the recognized location. As a result, the location information generator (not shown) provided in the cellular phone base station existing in the cell where the information replication device is located generates its own cell ID as the location information of the information replication device. The location information acquisition unit 220 provided in the target device or the target forming apparatus acquires the generated location information.

The location information acquisition unit 220 may not be directly input by the user in obtaining location information. This is because when the location information acquisition unit 220 receives and receives its location information from the user, incorrect location information may be obtained by the user's manipulation.

On the other hand, the location information guessing unit 230 supplies the location information that must be contained in the IN 2 to the inspection unit 250 in order for the information contained in the given document IN 2 to be duplicated. That is, the location information estimator 230 speculates and presents a possible example of the location information that should be inserted into the IN 2 in order to duplicate the information of the document IN 2 given to the location information extracting unit 210. To this end, it is preferable that the position information estimated to be inserted into IN 2 is prepared in advance by matching the obtained position information. The location information storage unit 240 stores the estimated location information matched for each acquired location information. However, according to the present invention, the location information estimation unit 230 and the location information storage unit 240 may not be provided. In this case, the location information obtained by the location information acquisition unit 220 is directly transmitted to the inspection unit 250.

The inspection unit 250 checks whether there is location information that matches the location information extracted by the location information extraction unit 210 and the location information obtained by the location information acquisition unit 220. For example, if the extended position information is included in the position information inserted into IN 2, the extended position information exists in the position information extracted by the position information extracting unit 210, and the inspection unit 250 acquires the position obtained in the extended position information. Check if the information exists.

On the other hand, the obtained position information is preferably information including the position information of the information replication apparatus. Furthermore, the obtained location information may also include other location information previously designated corresponding to the location information of the information replication apparatus.

The replica unit 260 and the user interface unit 270 operate in response to the result of the test by the test unit 250. More specifically, the duplicated unit 260 operates if there is a result of the test, but the user interface unit 270 operates if there is no result of the test.

The duplication unit 260 duplicates the information contained in the document IN 2. The duplication unit 260 may include a duplication information recording unit 262, an output image generating unit 264, an image forming apparatus unit 265, and a printing unit 268.

The duplication information recording section 262 stores the extracted position information. However, according to the present invention, the copy information recording unit 262 may not be provided. On the other hand, the output image generation unit 264 generates an output image that is an image of the result read by the position information extraction unit 210.

The image forming apparatus unit 265 forms an image of the generated output image. In addition, the printing unit 268 forms the formed image on a printing medium prepared in advance.

As described above, if the replica unit 260 is implemented as a laser beam printer, the image forming apparatus unit 265 may include an exposure unit 266 and a developing unit 267. At this time, the exposure unit 266 scans the provided photosensitive medium with a laser beam to generate an electrostatic latent image, and the developing unit 267 develops the generated electrostatic latent image to form an image thereof. Meanwhile, the printing unit 268 fixes the formed image on the print medium and outputs the formed image as a document.

On the other hand, if the replica unit 260 is implemented as an inkjet printer, the image forming apparatus unit 265 preferably includes an ink nozzle controller (not shown). At this time, the ink nozzle control unit (not shown) generates a control signal for controlling the degree of ejection of ink in accordance with the generated output image. On the other hand, the printing unit 268 injects the ink onto the print medium in response to the control signal to output the formed image as a document.

On the other hand, if the replica unit 260 is implemented as a latent heat printer, the image forming apparatus unit 265 preferably includes a thermal head controller (not shown). At this time, the thermal head controller (not shown) generates a control signal for controlling the degree of thermal degradation in accordance with the generated output image. On the other hand, the printing unit 268 heats the print medium in response to the control signal to output the formed image as a document.

Thus, if the information copying device provided with the copying unit 260 is a copying machine or a multifunction device having a copying function, the copying unit 260 copies the document IN 2 by copying the document IN 2. In this case, OUT 2 means a print medium to which IN 2 is copied.

Similarly, if the information copying apparatus provided with the copying unit 260 is a multifunction apparatus having a scanner or a scanning function, the copying unit 260 copies the information by scanning the document IN 2. In this case, OUT 2 means scan data having information contained in IN 2.

More specifically, if the information copying device provided with the copying unit 260 is a scanner or a multifunction device having a scanning function, the copying unit 260 may include a scanning unit (not shown), a scan data acquisition unit (not shown), and a scan data copying unit ( Not shown).

The scanning unit (not shown) scans the given document, and the scan data obtaining unit (not shown) acquires the scan data generated by the scanning. The scan data copy unit (not shown) may copy the obtained scan data.

The user interface unit 270 informs that duplication cannot be performed. OUT 3 means the known content. Meanwhile, an illegal copy attempt notification unit (not shown) may be connected to the user interface unit 270. If, as a result of the inspection by the inspection unit 250, if it is determined that it does not exist, the illegal copy attempt notification unit (not shown) indicates that "an illegal copy was attempted", the host device or the image provided at the location indicated in the location information extracted from IN 2 The forming apparatus can be informed.

On the other hand, if the location information is watermarked and inserted in IN 2, even those who attempt to illegally copy the location information do not recognize the existence of the location information, thereby preventing the inserted location information from being deliberately damaged in IN 2.

However, the location information input unit 110 may input the location information directly input by the user to the location information insertion unit 120.

The position information insertion unit 120 inserts the input position information into the print data IN 1 (step 320). Thereafter, the image forming unit 130 prints the print data into which the position information is inserted as a document on a print medium.

More specifically, the exposure unit 132 of the image forming unit 130 forms an electrostatic latent image of the print data into which the position information is inserted (step 332). After operation 332, the developing unit 134 of the image forming unit 130 develops the formed electrostatic latent image to generate an image (operation 334).
