[Industrial applications]
The present invention relates to an image forming apparatus such as a color copier that prohibits copying of banknotes and securities, etc., in which counterfeiting is prohibited. More specifically, the present invention relates to an original and data for forgery prevention such as securities. The present invention relates to an image forming apparatus that performs collation, disables copying when the similarity is high, and executes normal copying when the similarity is low.
[0002]
[Prior art]
In the conventional image forming apparatus, in order to prevent duplication of bills or securities, etc., copy output is prohibited or disabled when mainly regarded as counterfeit copying by counterfeit copying and pattern matching. Alternatively, a warning is displayed to prevent forgery copying.
[0003]
FIG. 4 is a flowchart showing a conventional forgery copy prevention processing operation. In the figure, when this processing is started, first, an original is set at a predetermined position (in this case, an ADF original platen), and the number of copies is input using a ten-key (not shown) (S401). Next, the set original is read by a scanner (S402), and the image data of the read original is compared with securities data registered in advance (S403). Then, as a result of the comparison, it is determined whether or not the two are similar (S404). If it is determined that they are similar, the copying process is started (S405), and the recording paper on which the document data is recorded is discharged (S406).
[0004]
On the other hand, if it is determined in step 404 that they are similar, a warning is displayed (S407), and it is determined whether or not the content of the warning is OK (S408). If it is determined in step 408 that the content of the warning display is OK, the copy process is stopped (S409). If it is determined in step 408 that the content of the warning display is not OK, the operation of the machine is stopped (S410), and it is determined whether or not a restart is necessary (S411). If it is determined that a restart is necessary, restart processing and document ejection are performed (S412), and the process returns to step 401.

[Problems to be solved by the invention]
However, in the conventional image forming apparatus as described above, copying is stopped even when the image is stored as a memorial, for example, in a case where the document is close to a security but is not a forgery. In addition, when an illegal forgery copy is made, there is a problem that the device can be specified, but the actor is not easily specified.
[0006]
The present invention has been made in view of the above, and enables the copying in the case where it is close to securities but is not an illegal forgery, and also accurately identifies the actor in the case of making an illegal forgery. The purpose is to make it easier.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in an image forming apparatus according to claim 1, an image forming apparatus that reads an original to form an image determines an image similarity between a security and the original in a stepwise manner. A data judging unit for prohibiting copy processing of a document having the first similarity or higher by the image data judging unit; and performing the first similarity at or above a second similarity lower than the first similarity. And a control unit for performing a normal copy process on the document having the second similarity or less, the control unit further performing the copy process. For each time, fingerprint data recognizing means for recognizing a worker's fingerprint, fingerprint data recognizing means for registering a fingerprint recognized by the fingerprint data recognizing means, and document data when the fingerprint is registered by the fingerprint data registering means. Source to remember Those comprising a data storage means.
[0008]
Further, in the image forming apparatus according to the second aspect, the control means stops the operation of the apparatus for a predetermined time when an attempt is made to copy the same securities within a predetermined time.
[0010]
[Action]
In the image forming apparatus according to the present invention (claim 1), the similarity between the security and the document is determined stepwise by the image data determination means, and based on the determination result, the control means determines the similarity between the security and the original. The copying process is prohibited for the original document, and only one document is copied for the original document having the second similarity lower than the first similarity and not lower than the first similarity. The originals below the standard are subjected to a normal copying process, and each time the copying is performed , the original data is further stored in the original data storage means. At that time, the fingerprint data of the copying worker is recognized and registered.
[0011]
Further, in the image forming apparatus according to the present invention (claim 2), when the control unit attempts to copy the same securities within a predetermined time, the operation of the apparatus is stopped for a predetermined time.
[0013]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a block diagram illustrating a configuration of an image forming apparatus according to the present invention. In the figure, reference numeral 101 denotes a scanner for optically reading a document to be copied and obtaining image data using a photoelectric conversion element such as a CCD, and 102 denotes image data from the scanner 101, for example, a RAM or an external storage device in the main body. A document data storage unit 103 to be used for performing fingerprint recognition generally used by placing a finger on an operation button (not shown) of the apparatus, and fingerprint data for recognizing the fingerprint data The recognition unit.
[0014]
Reference numeral 104 denotes a fingerprint data registration unit for registering fingerprint data, and reference numeral 105 denotes a security data storage unit in which security data is stored. For example, an external storage device or an internal ROM is used. The storage pattern of the securities data storage unit 105 is for recognizing various securities patterns, for example, by using a recognition method used for a bill change machine or the like. Reference numeral 106 denotes an image data determination unit for comparing data in the security data storage unit 105 with image data read by the scanner 101; 107, a display unit for displaying the status of the apparatus; and 108, image data recorded on recording paper. Printer to print out. A control unit 109 for controlling the entire apparatus includes an original data storage unit 102, a fingerprint data recognition unit 103, a fingerprint data registration unit 104, a security data storage unit 105, and an image data determination unit 106. Have been.
[0015]
Next, the operation of the image forming apparatus configured as described above will be described. FIG. 2 is a flowchart showing the processing operation according to the present invention. In the figure, when this processing is started, first, an original is set at a predetermined position (in this case, an ADF original platen), and the number of copies is input by a ten-key (not shown) (S201). Next, the set original is read by the scanner 101 (S202), and the image data of the read original is collated by the image data determination unit 106 with reference to the image data stored in the securities data storage unit 105. Execute (S203). At this time, even when the bill is affixed to plain paper, it is recognized as the "same thing".
[0016]
Further, it is determined whether or not the similarity between the manuscript data and the securities data is 80% or more as a result of the collation processing in step 203 (S204). Note that the percentage value of the similarity is obtained by dividing the number of similar points by the total of the measurement points. When it is determined in step 204 that the similarity is not 80% or more, that is, when it is determined that the original data is not forged data, the read image data is subjected to image forming processing by the printer 108 (S205). Then, the recording paper is discharged (S206).
[0017]
If it is determined in step 204 that the similarity is 80% or more, it is further determined whether the similarity is 95% or more (S207). If it is determined in step 207 that the similarity is 95% or more, that is, if the original to be copied is a forgery target, the copying process is stopped (S208).
[0018]
If it is determined in step 207 that the similarity is not 95% or more, a warning is displayed on the display unit 107 indicating that only one copy is possible (S209). Next, it is determined whether or not the content of the warning display is OK (S210). When it is determined that the content of the warning display is not OK, it is further determined whether or not copying is not allowed (S211). If it is determined that copying is not permitted, the original is received (S212).
[0019]
On the other hand, if it is determined in step 210 that the content of the warning display is OK, the image data of the document and the fingerprint of the copy operator are registered (S213). This is to store the original contents and fingerprints as backup data in the original data storage unit 102 and the fingerprint data registration unit 104 in order to prevent misuse of securities by copying. At this time, the fact that the backup data remains is displayed on the display unit 107 so that there is no inconvenience at the time of input. Next, a copy operation is started (S214). Then, it is displayed on the display unit 107 that the same copy processing cannot be performed within a predetermined time (S215). Next, the recording paper on which the image is recorded is discharged, and the original is received (S216).
[0020]
In the above description, the reason why only one copy can be performed is to avoid abuse of similar objects. Also, in order to prevent the abuse of securities by copying them, for example, to prevent the same securities from being copied for three months, use the backup data of the document contents and fingerprints to change the issue number, print number, etc. You can identify whether they are the same.
[0021]
FIG. 3 is a flowchart showing another processing operation according to the present invention. Note that this processing is the same as that of the above embodiment up to the discharge of the first document, and the following description will also include that portion. In the figure, when this processing is started, first, an original is set at a predetermined position (in this case, an ADF original platen), and the number of copies is input by a ten-key (not shown) (S301). Next, the set document is read by the scanner 101 (S302), and the image data of the read document is collated by the image data determination unit 106 with reference to the image data stored in the security data storage unit 105. Execute (S303). Further, it is determined whether or not the similarity between the manuscript data and the securities data is 80% or more as a result of the above-described collation processing (S304). Here, when it is determined that the similarity is not 80% or more, that is, when it is determined that the original data is not forged data, the read image data is subjected to an image forming process by the printer 108 (S305), and is recorded. The paper is discharged (S306).
[0022]
If it is determined in step 304 that the similarity is 80% or more, it is further determined whether the similarity is 95% or more (S307). If it is determined in step 307 that the similarity is 95% or more, that is, if the original to be copied is a forgery target, the copying process is stopped (S308).
[0023]
If it is determined in step 307 that the similarity is not 95% or more, a warning is displayed on the display unit 107 indicating that only one copy is possible (S309). Next, it is determined whether or not the content of the warning display is OK (S310). If it is determined that the content of the warning display is not OK, it is further determined whether or not copying is not allowed (S311). If it is determined that copying is not permitted, the original is received (S312).
[0024]
On the other hand, if it is determined in step 310 that the content of the warning display is OK, the image data of the document and the fingerprint of the copy operator are registered (S313). Next, a copy operation is started (S314). Then, it is displayed on the display unit 107 that the same copy processing cannot be performed within a certain period of time (S315), the recording paper on which the image is recorded is discharged, and the original is discharged (S316). Next, it is determined whether or not all copy processes have been completed (S317). Here, when it is determined that all the copying processes have been completed, the standby mode is set (S318). If it is determined in step 317 that all copy processing has not been completed, the next original is transported by the ADF (not shown) (S319), and the process returns to step 302, where the original is scanned by the scanner 101. And the same processing as described above is executed.
[0025]
【The invention's effect】
As described above, according to the image forming apparatus of the present invention (claim 1), the similarity between the security and the document is determined stepwise by the image data determination unit, and the control unit is determined based on the determination result. Prohibits the copying process for an original with a first similarity or higher and only copies one original for a second or higher similarity lower than the first similarity and lower than the first similarity. and copy processing, the second similarity following manuscript for you to perform normal copying process, and disables recopying of the original near the forgery preventing a large amount of copy processing, each time the copying action In addition, the manuscript data is stored in the manuscript data storage means. At that time, the fingerprint data of the copying worker is recognized and registered. Therefore, when the securities are copied by any method, the pursuit search is performed. It can be done easily.
