  FIG. 2 is a diagram showing an example of a first processing procedure in the image processing system according to the present invention, and (101) to (114) in FIG. 2 show each step.

  Hereinafter, the registration / copying process in the image processing system of the present invention will be described in detail with reference to FIGS.

  First, the user designates data to be printed from the stored data to the printing apparatus 1 in FIG. The designation method here may be panel operation or a printer driver. The printing apparatus 1 confirms that the designated file name is included in the management file DB in the data part 2a of the portable memory, and if it is included, acquires the management number corresponding to the file name. Then, using the acquired management number, the server address of the data part 2a, and the user ID, the data search part 3b of the server 3 is accessed and desired data is transferred to the printing apparatus 1 to perform printing processing. Reference numeral 4 denotes an output sheet created by the printing process, and the management number is printed in the form of characters or barcodes. 5 is a diagram in which the user and his / her customer are proceeding with the negotiation while looking at the output sheet 4, and 6 is an output sheet whose contents have been updated by the negotiation 5.

  When the output paper 6 is read by the scanner of the printing apparatus 1, the registration number is identified from the data scanned by the process of step (101) in FIG. In step (102), the portion overwritten by handwriting from the scan data is extracted to create handwritten portion data for storage. In step (103), a hash function is performed from the handwritten portion data by the method shown in FIG. A message digest value is extracted as a feature quantity. In step (104), the user ID stored in the data portion 2a, the created handwritten portion data, and the feature amount are sent to the server 3. In step (109), the reception date and time of the data sent from the printing apparatus 1 is specified, and in step (110), a uniquely determined registration number is determined. In step (111), the reception date and time, registration number, user ID, feature amount, and handwritten part data required for original guarantee are registered. In step (112), the registration number and reception date and time are sent to the printing apparatus 1. . In step (105), the registration number and the reception date and time sent from the server 3 are received, a new management file is created together with the scan data registration number acquired in step (101), and stored in the data portion 2a of the portable memory. . In step (106) of FIG. 2, the registration number of the scan data is transmitted to the server 3, and in step (113), stored data corresponding to the management number transmitted from the printing apparatus 1 is stored in the server 3. Find out of the device. In step (114), the found saved data is sent to the printing apparatus 1. In step (107), the saved data sent from the server 3, the handwritten data, and the new data issued in step (110) are sent. Print data is created from the registration number and the digital watermark of the feature amount, and printing is executed in step (108).

  FIG. 3 is a diagram for explaining the print data creation (step (107)) processing of FIG.

  303 indicates that a new registration number is added to the print data, and 305 indicates that the digest value is superimposed on the print data as a digital watermark by the method shown in FIG.

  FIG. 4 is a diagram for explaining the feature amount extraction (step (103)) in FIG.

  In the present embodiment, a message digest value is calculated using a hash function called MD5. For example, MD5 is used as a message digest function in PGP (Pretty Good Privacy), which is one of encryption programs currently in practical use.

  FIG. 5 is an explanation of adding a message digest value as digital watermark information to a print image. The digital watermark technique is a known technique and is described in detail in, for example, Japanese Patent Application Laid-Open No. 9-191394.

  Next, a case where the originality of the printed output paper is confirmed will be described.

  FIG. 6 is a flowchart for explaining the original registration confirmation process for a printed output sheet in the image processing system according to the present invention.

  Steps (601) to (606) are parts for explaining processing of the printing apparatus 1. In step (601), the original guarantee code-added output paper 7 is read from the reader 8, and the registration number and the digest value are extracted. In step (602), the feature amount read from the digest value and the registration number are sent to the server 3.

  In step (603), the confirmation result in the server 3 is received. If the confirmation result is affirmative in step (604), the process proceeds to step (605) and the registration confirmation shown in FIG. 7 is printed. If the confirmation result is negative, the process proceeds to step (606), and in FIG. Print the registration unconfirmation shown.

  Steps (607) to (610) are parts for explaining the authentication process of the server 3.

  In step (607), the feature amount read from the digest value and the registration number are received, and the corresponding data is specified. Then, the feature quantity stored in the storage device of the server 3 is compared with the feature quantity. If the determination result is a positive result, the process proceeds to step (608), and if the determination result is negative, the process proceeds to step (609), and the negative result is assigned to the confirmation history. Next, in step (610), the determination result is sent to the printing apparatus 1.

  Since the information on the original guarantee code-added output sheet 7 and the information registered in the server 3 correspond to each other at the time of registration, an error is displayed if they do not match.

  In addition, when the electronic data stored in the storage device of the server 3 is not found, a message “No corresponding data is found” is displayed to notify the user.

  In general, when signing a contract, there are many cases in which a prepared document is overwritten and updated by discussion between the parties. (Example: Real estate rental contract). In such a workflow, it is considered that a system like the present invention is required when the original document guarantee is advanced.
