[0008]

In the electronic authentication device according to the first aspect of the invention, the specific information extracting means extracts specific information from information such as a document stored in the information storage means in accordance with a predetermined method, and the synthesizing means extracts the specific information from a stamp image or the like. The authentication means synthesizes the authentication image with the authentication image corresponding to the information.
Since authentication is performed by being added to the information by storing it in the authentication area, when information such as a document is changed, the change can be easily detected by checking the added specific information.

In the electronic authentication device according to a second aspect of the present invention, the specific information extracting means extracts the specific information from the authenticated information again by the same extraction method as the specific information added to the authenticated information, Since the matching means compares and matches the two, it can be checked whether or not the information has been processed.

[0010]

[Embodiment 1] An embodiment of the present invention will be described below with reference to the drawings. FIG.
FIG. 1 is a diagram showing a configuration example of the present invention. In FIG.
7 is a document information extracting means, 8 is a document information extracting method storing means, 9 is a collating means, and 10 is a synthesizing means for synthesizing the specific information of the document extracted by the document information extracting means 7 with the seal image. FIG. 2 is a diagram for explaining the operation of the document information extracting means 7, and in FIG.
1 is a seal area corresponding to the document 5 and 12 is a seal image 6
Is the specific information to be combined. FIG. 3 is an image diagram of a document including a seal using the present embodiment. In the drawing, reference numeral 13 denotes a specific information image displayed as an image of the specific information 12 combined with the seal image 6.

First, the stamping operation will be described. The document 5 to be stamped is extracted from the document file 4. The document information extraction method storage means 8 stores one or more methods for extracting specific information from a document, and the method corresponds to information for selecting a method such as a date or a day of the week. Is based on For example, if the use date is November 11, the document information extraction means 7 selects a corresponding method from the document information extraction method storage means 8 and extracts the document specific information 12 from the document 5. As an example of the extraction method, a sum total of codes representing one document (ABAFC4
3F), and this is used as the document specific information 12.

Next, the synthesizing means 10 extracts the seal image 6 corresponding to the purpose of the date of use from the seal image file 2 and stores the specific information 12 in a predetermined position of the seal image in the work area for the synthesizing means 10. Write and combine
I do . The image synthesized by the synthesizing means 10 is
The seal image should be pasted by the seal means 3
It is pasted on the seal area 11 corresponding to the document .

When the stamped document 5 is printed in this way, the stamped area 11 is printed as an image, so that the specific information 12 is printed as a specific information image 13 as shown in FIG. That is, although the specific information 12 is stored as a code, a special image corresponding to the code is formed at the time of printing (however, in this example, the character code ABAFC43F is output as image data as it is. It does not expect a specific output image in advance, but will result in some image being output). Therefore, even if the image of the seal is cut and pasted into another document and attempted to be illegally used, the specific information image 13 is an image dependent on the document that generated the specific information 12 on which it is based. Can be prevented from being diverted.

Since the area to which the specific information 12 is added is a part of the mark area 11, that is, an image area, the specific information 12 is stored in a header portion or the like in the code information 5 a of the document 5. There is no particular need to provide an area. As described above, by storing the specific information 12 in the image area, it is not necessary to add special information to the document structure. Therefore, the file configuration may be the same as the conventional one, and this embodiment is applicable. The same treatment can be applied to both documents with and without documents, or documents with and without seals.

As described above, in this embodiment, in an electronic stamping device for stamping a document or a slip which is input by an input means such as a keyboard and is described electronically, a stamp image file for storing a stamp image, There are specific information extracting means for extracting information specifying the document or voucher to be stamped based on the contents of the document, and synthesizing means for synthesizing the specific information with the mark image. An electronic stamping device has been described which is provided with a stamping means for inserting a stamping image in which specific information is synthesized.

Further, the above-mentioned electronic stamp device has a date in the stamp image stored in the stamp image file,
The date is changed by the date changing means.

Further, the specific information extracting means has a document information extracting method storing means for storing a method for extracting the specific information from the contents of a plurality of documents and slips, and means for selecting this method according to a predetermined rule. It is characterized by. By changing the document information extraction method according to a predetermined rule by the document information extraction method storage means, the document information extraction method can be more easily detected than when the contents of the document are changed.

Embodiment 2 FIG. In the above embodiment, the case where the synthesizing unit 10 synthesizes the specific information 12 with the seal image 6 and then stores the specific information 12 in the seal area 11 has been described, but the synthesizing unit 10 stores the seal image 6 in the seal area 11 first. After that, the specific information 12 may be stored while being superimposed on the predetermined position. Alternatively, a place for storing the seal image 6 and the specific information 12 is separately provided in the seal area 11 in advance, and the synthesizing means 10 stores the seal image 6 and the specific information 12 at the respective locations, thereby combining the two. You may. Thus, in this electronic Approval device, in the synthesis section, it is possible to select and use according to the laws which are decided more synthetic methods.

Embodiment 3 FIG. Next, a description will be given of a collation operation for inspecting whether the seal imprinted on the document is correct. The control means 1 detects the document identification information 12 from a predetermined position in the seal area 11 of the document 5 to be collated. Next, the stamp date is input by an input means such as a keyboard, a method corresponding to the date is selected from the document information extraction method storage means 8, and the sum of the codes of the document 5 is obtained by the document information extraction means 7. Next, the collating means 9 compares the total sum obtained here with the specific information 12 previously obtained, and if they match, determines that the seal has been correctly performed.

As described above, in this example, a seal image file for inputting a seal image by using an electronic seal device which seals a document or a slip which is input by an input means such as a keyboard and is electronically described. means, the specific information extraction means for extracting information for identifying it according to a predetermined method from the contents of the document or documents to be Approval by a synthesizing means for synthesizing the specific information to the Approval image, the document Inserts and stores a seal image combining the specific information at a predetermined position of the slip, and when the stamped document or slip is received, extracts the synthesized specific information from the seal image, and Or having matching means for checking with the information processed according to the above-mentioned predetermined method from the contents of the slip. That described the electronic seal of approval apparatus.

Embodiment 4 FIG. In the above, the document information extraction method storage means 8 stores the document information
Although the output method is associated with the date, it may be associated with another method such as a department name. Further, as the document information extraction method, an example in which the sum of codes is obtained has been described, but another method such as sampling and adding may be used. Also, the example has been described in which the extracted specific information has the code information entered in a fixed position as it is, but at the time of collation, the position can be freely changed and the information can be freely converted if it can be restored. In addition, each unit of the electronic seal device may be separately arranged on a network. Further, in the above-described embodiment, the case of a document has been described. However, other information such as voice information and a database may be stamped. In addition, the seal is an example of the case where the information is authenticated, and may be the case where the authentication is performed using an image such as a signature or other symbols or marks.

[0022]

As described above, according to the present invention, the specific information extracted from the document is added to the image of the seal, so that if the contents of the document are falsified after the seal, it can be easily found. Become. Also, in a separate authentication area from the document
Because the authentication image is stored, the authenticated document
It can be treated the same as a document.
