[0002]
[Prior art]
2. Description of the Related Art Conventionally, a printing system that prints a document with a guarantee of originality has been proposed as described later.
[0003]
For example, in Japanese Patent Laid-Open No. 2000-285024, a file indicating an original when storing electronic data for the purpose of giving the electronic information the properties of the original paper and enhancing the proof of the electronic information. An attribute code is added and stored in a state that can be distinguished from at least other electronic data.
[0004]
Japanese Patent Laid-Open No. 2001-202436 discloses an electronic application system for applying electronic documents from a terminal via a network for the purpose of providing an electronic application system that ensures the safety of stored application documents over a long period of time. The electronic application system is provided with a document storage device, means for calculating a falsification detection code from information including a document transmitted from a terminal, and means for storing the information in the document storage device together with the falsification detection code. Have.
[0005]
In addition, the applicant previously added a message digest value on a print in a form that is difficult to falsify in order to improve the reliability of the print related to the electronic signature in Japanese Patent Laid-Open No. 2000-224407. Thus, the value of the electronically signed document data can be improved.

[0068]
First, in step (401), the original guarantee code-added print 111 output from the printer 110 is read by the reader 101, for example, the registration number / date and time 402 in the header area, the message digest value 404 as the feature amount, and the sign area. Image data is extracted. In step (402), for the image data in the sign area, the area for the sign data image secured on the RAM 2 is divided into blocks as shown in FIG. Color information (R, G, B) and block coordinates (x, y) are extracted as feature quantities.
[0069]
In step (403), the registration number, the text image feature amount, and the signature area feature amount are sent to the original registration server 120.
[0070]
In step (404), the result information in the original registration server 120 is received. Next, in step (405), the registration result is determined from the result information received from the original registration server 120. When the registration result is acceptable, the registration confirmation is performed in step (406) as shown in FIG. The message “Signature has been registered” is displayed on the CRT 10 and the process is terminated.
[0071]
On the other hand, if the registration result is NG in step (405), a message “Signature could not be registered” indicating registration confirmation is displayed on CRT 10 in step (407), as shown in FIG. Display and finish the process.
[0072]
FIGS. 11A and 11B are diagrams showing an example of a registration confirmation result printing in the image processing system according to the present invention. FIG. 11A is an example of a signature registration OK message display, and FIG. It is an example of a message display.
[0073]
Hereinafter, processing of the original registration server 120 shown in steps (410) to (414) will be described.
[0074]
First, in step (410), the registration number / date / time data 402, message digest value 404, and sign area information sent from the user personal computer 100 are received, and the registration number / date / time data 402, message digest value 404 and original data are received. The contents of the registration file 121 (other than the signature data) are collated to determine whether or not they match, and if they match, it is registered in the confirmation history item of the original registration file 121 in step (411). Stores availability and date / time.
[0075]
In step (413), the sent sign area information is registered in the sign data. In step (414), the confirmed determination result is notified to the user personal computer 100, and the process is terminated.
[0076]
On the other hand, if it is determined in step (410) that they do not match, the non-registration determination and date / time are stored in the confirmation history item of the original registration file 121, and the process proceeds to step (414), where the determination result is Is notified to the user personal computer 100, and the process ends.
[0077]
Thus, the signature information of the original registration user is registered in the original registration server 120 as a file.

In addition, the control program corresponding to each step is loaded onto the RAM 2 from the external memory 11 or the like and executed by the CPU 1. Hereinafter, the print processing will be described in detail.
[0079]
First, in step (801), the original guarantee code-added print 111 output from the printer 110 is read by the reader 101, and for example, the registration number / date and time 402 and message digest value 404 on the header area are extracted. In step (802), the image data of the signature area 203 on the original guarantee print 111 is divided into blocks as shown in FIG. R, G, B) and block coordinates (x, y) are extracted as feature quantities and sent to the original registration server 120 together with the data extracted in step (801).
[0080]
In step (803), confirmation information at the original registration server 120 is received.
[0081]
Next, when the content of the confirmation information received from the original registration server 120 is determined in step (804) and it is determined that the confirmation information is affirmative, registration is performed in the format shown in FIG. 13 in step (805). The confirmation certificate is printed by the printer 110, and the process ends.
[0082]
On the other hand, if it is determined in step (804) that the confirmation information is negative, in step (806), a registration unconfirmation is printed in the format shown in FIG. 14, and the process ends.
[0083]
FIGS. 13 and 14 are diagrams showing a registration confirmation result printing example in the image processing system according to the present invention. FIG. 13 is a confirmation OK example, and FIG. 14 is a confirmation NG example.

In step (811), in the confirmation history item of the original registration file 121, an affirmative determination is made. An additional process for storing the confirmation date and time is performed, and in step (813), the confirmation information (including confirmation number, confirmation result, confirmation date and time) result confirmed in step (810) is notified to the user personal computer 100, and the process is performed. finish.
[0086]
On the other hand, if it is determined in step (810) that they do not match, negative determination and confirmation date and time are stored in the confirmation history item of the original registration file 121 in step (812), and in step (813). The confirmation information (including confirmation number, confirmation result, confirmation date and time) confirmed in step (810) is notified to the user personal computer 100, and the process is terminated.
[0087]
[Second Embodiment]
