Problems solved by technology

[0007] (1) Each time the original document is scanned, the operation of adding a time stamp is required, thus reducing the efficiency of electronic work, and the cost of time stamping increases proportionally to the number of scans performed
[0008] (2) When performing signature processing and time stamping processing on scanned documents with an external device (such as a PC, etc.) connected to the scanner, the operator who has the signature right may forge the scanned document

Embodiment Construction

[0017] Embodiments of an image reading device, an electronic document generating method used in the image reading device, and a storage medium storing an electronic document generating program of the present invention will be described with reference to the drawings.

[0018] figure 1 is a block diagram showing the functional configuration of the scanner 10 for performing time stamp processing for generating submission data for scanned documents and an example of the configuration of an electronic document generation system including the scanner 10 .

[0019] exist figure 1 In this case, the scanner 10 executes a digital signature on scanned image data 21 read from a scanned document 20 .

[0020] In addition, the scanner 10 has a time stamp function which obtains a TST (Time Stamp Token) 31 from a TSA (Time Stamp Authority) 30 connected through a network 50 as a function for allowing checking to observe that the scanned image data 21 was at a specific time. The submitted do...

Abstract

An image reading apparatus which reads an original document and generates a digitized scanned document, and which includes a document storage section that stores the scanned document, a document bundling section that identifies one or more scanned documents stored by the document storage section, and bundles the identified documents into one document, and a time stamp affixing section that creates a digital signature of the document bundled by the document bundling section, and affixes a time stamp.

Description

technical field [0001] The present invention relates to an image reading device, an electronic document generation method, and a storage medium storing an electronic document generation program, and to a technique for attaching a time stamp to an electronic document requiring authentication. Background technique [0002] Conventionally, an image reading device having a digital signature section (hereinafter, such a device will be referred to as a scanner) performs digital signature processing and time stamp processing for each specific scanned image. [0003] Furthermore, by using the technique involving a time stamp server and an authentication server given in Japanese Patent Application Laid-Open No. 2003-244139, it has been possible to verify that electronic document data existed before a certain time, and furthermore, if a signed document is falsified, Then the forgery of the signed document can be detected. [0004] In addition, according to the Electronic Document Law...
