In the attribute information 213, various attribute information related to the image to be registered such as the type of image information, department information for executing the registration process, and image information generation date / time information are entered. In the example shown in FIG. 2A, the registration destination b is selected by the user, the attributes 2, 4, and 9 are checked as attribute information, and the registration scheduled image information 220 has the attributes 2, 4, and 9. , It is scheduled to be registered in the registration destination b (data registration unit b132 in FIG. 1).

  Furthermore, the user executes a user ID and password input process via the character information input means 112. FIG. 2B shows a user ID and password input processing screen presented on the user interface constituting the character information input means 112. The user applies a keyboard or the like to the processing screen and inputs a user ID and a password. The user ID and password are given in advance to the user who executes the data registration process, and are registered as user information in the user information storage unit 127 of the server 120. The user ID and password are information applied to the determination of access authority to the database 130, and it is necessary to prevent leakage to the outside as confidential information.

  The cover page image data recorded by the image information input unit 111 such as a scanner and the user ID and password input by the user via the character information input unit 112 are recorded in the code information synthesis unit 113. Transferred.

  The code information synthesizing unit 113 converts the user ID and password input by the user via the character information input unit 112 into code information, and the cover read by the image information input unit 111 using the converted code information as image data. A process of combining the image data on the page is executed. This process will be described with reference to FIG.

  FIG. 3A shows the cover page image data 230 generated by the synthesizing process of the code information synthesizing unit 113. The cover page image data 230 is output to the data transmission path 150 via the transmission unit 114 and transmitted to the server 120 together with the scheduled registration image information 220 read by the image information input unit 111.

  The cover page image data 230 generated by the synthesizing process of the code information synthesizing unit 113 is on the image data of the cover page (the cover page 210 in FIG. 2A) read by the image information input unit 111 such as a scanner. It is configured as data in which image data of code information (two-dimensional code) generated based on the user ID and password input by the user via the character information input means 112 is pasted.

  In the example shown in FIG. 3A, three two-dimensional codes are shown, but the leftmost two-dimensional code is the cover page identification information 211 printed on the cover page in advance. The two two-dimensional codes shown adjacent to each other are two-dimensional codes generated by the code information synthesizing unit 113 based on the user ID input by the user via the character information input unit 112, and the user ID two-dimensional code 215. Similarly, the password two-dimensional code 216 generated by the code information synthesizing unit 113 based on the password input by the user via the character information input unit 112.

  The cover page image data 230 shown in FIG. 3A is data that exists as image data, and does not exist as a paper medium. A cover page 210 illustrated in FIG. 2A exists as a paper medium. That is, confidential information such as a user ID and a password is not recorded on the cover page 210 as a paper medium, but is generated as image data by the code information synthesizing unit 113 of the client 110 when the data is transferred from the client 110 to the server 120. 3 is synthesized on the cover page image data read by the image information input means 111, etc., and the cover page image data 230 shown in FIG. 3A is generated and transmitted to the server.

  In this example, the code information synthesizing unit 113 converts confidential information such as a user ID and a password into two-dimensional code information, generates an image corresponding to the converted two-dimensional code, and synthesizes the cover page. However, the code information is not limited to the two-dimensional code, and other code information can be applied as long as the code information is different from the character information of the user ID and password, such as barcode, other encoded data, and encrypted data. Good. Although the user ID and password are generated as separate code information here, the user ID and password may be generated as one piece of code information.

  The cover page image data 230 shown in FIG. 3A generated by the code information synthesizing unit 113 is transferred to the data transmission path 150 via the transmission unit 114 together with the registration scheduled image information 220 read by the image information input unit 111. Is output and transmitted to the server 120.

  Next, processing on the server 120 side will be described with reference to FIG. The server 120 acquires transmission data from the client 110 in the information acquisition unit 121. The cover page included in the acquired data is analyzed by the cover page analysis unit 122. The cover page that is analyzed by the cover page analyzing unit 122 is the cover page image data 230 shown in FIG. 4A, and corresponds to the cover page image data 230 described with reference to FIG. .

  The cover page analysis unit 122 analyzes the information included in the cover page image data 230 based on the information stored in the cover page analysis information storage unit 123, that is, confirmation of a registration destination or the like or addition on the client side. 2D code information extraction processing is performed. The code information analyzing unit 124 analyzes the two-dimensional code information added by the client extracted by the cover page analyzing unit 122.

  A specific example of processing executed by the image deleting unit 125, that is, processing for deleting code information corresponding to the user ID and password from the cover page image data 230 will be described with reference to FIG.

  FIG. 5A shows cover page image data 230 received from the client 110 by the server 120. The cover page image data 230 includes cover page identification information 211, a user ID two-dimensional code 215, and a password two-dimensional code 216 as a two-dimensional code. The image deleting unit 125 deletes the user ID two-dimensional code 215 and the password two-dimensional code 216 as confidential information, which are two-dimensional code information added by the client based on the code information extracted by the cover page analyzing unit 122. Execute. The result data of the deletion process is registered cover page image data 250 shown in FIG.

  In the registered cover page image data 250 shown in FIG. 5B, the cover page identification information 211 is left as it is, but the user ID two-dimensional code 215 and the password two-dimensional code 216 as confidential information are deleted. Other registration destination information and attribute information are unchanged. The registered cover page image data 250 shown in FIG. 5B is registered in the database. The registered cover page image data 250 shown in FIG. 5B corresponds to the cover page 210 as a paper medium described above with reference to FIG. That is, the cover page information does not describe the user ID and password information as confidential information.

  The information registration unit 126 stores the registered cover page image data 250 shown in FIG. 5B in the designated registration destination of the database 130. At this time, the information registration unit 126 collates the user ID and password information acquired from the code information analysis unit 124 with the user information stored in the user information storage unit 127. As a result of the collation, the access authority to the database designated as the registration destination is determined. Only when it is determined that the access authority exists, the registration process to the specified database is performed. If it is determined that there is no access authority, the data registration work is not performed. In this example, since the registration destination b is designated as the registration destination designation information on the cover page, the registration data set 300 of the cover page and the image information associated with the cover page is stored in the data registration unit b132. .

  The data stored in the database 130 does not include the user ID two-dimensional code and password two-dimensional code as confidential information. Even if the data is exploited by unauthorized access to the database 130, the user ID and password are leaked. There is nothing.

  Also, on the client side, the paper medium on which the user ID and password are recorded is not left, and leakage of the user ID and password via the paper medium can be prevented. Furthermore, on the data communication path from the client to the server, the user ID and password are not converted as character information, but are converted into encoded codes, in this example, two-dimensional codes, and transmitted as image data. It becomes possible to increase the difficulty of analyzing the user ID and password by reading data from the communication path.

  Next, the client processing procedure and the server processing procedure will be described with reference to the flowcharts of FIGS. First, client processing will be described with reference to FIG.

  A client-side user who wants to send image information to the server and register it in the database first reads the image information with an image information input means 111 (see FIGS. 1 and 2) such as a scanner in step S101. Necessary information is recorded on the cover page and read by image information input means such as a scanner. This cover page is a cover page as a paper medium described above with reference to FIG. 2A, and is based on identification information indicating that it is a cover page, registration destination designation information, data attribute information, and the like. The cover page is configured and does not include confidential information such as a user ID and password.
