摘要： When input data (f0) is read into a digital signature generating apparatus, a hash value (h0) is calculated. The hash value (h0) is stored to a storage area (M1), which has the highest priority rank among 5 storage areas. Subsequently, when input data (f1) is read in, a hash value (h1) is calculated. Since the storage area (M1) is already occupied by the hash value (h0), the hash value (h0) is read out from storage area (M1), emptying the storage area (M1). The read hash value (h0) and the hash value (h1) are concatenated, forming a concatenated hash value (h0|h1) and a hash value (h0,1) is calculated. The hash value (h0,1) is stored to a storage area (M2), which has the highest priority rank after the storage area (M1). When input data (f2) is read in, a hash value (h2) is calculated and stored to the storage area (M1).

摘要： An image managing method includes dividing the original moving image into a header and a body and generating the group hash value of the header portion, generating the hash value of each item of still image data, connecting the group hash value of the header portion and the hash value of each item of still image data to generate connected hash values, generating a group of the connected hash values as a hash value list, generating the hash value of a Huffman table on the basis of cutting out one still image, and signing to generate signature information of the original moving image, using the group hash value of the header portion, the hash value of the Huffman table, and the hash list as verification data of the original moving image, by adding a digital signature of a video recording terminal to it.

摘要： An electronic image data verification program disclosed herein is capable of detecting presence or absence of a change, specifying a changed portion (the position of a change) if present, and making the presence or absence and the changed portion provable to third parties, by generating partial signature information separately from electronic image information to be registered, by dividing and maintaining the partial signature information, and by clearly separating functions/roles of the electronic image information (original information) and the partial signature information (verification information). The present invention comprises: a partial signature information generation section 40 that uses partial information of electronic image information, to generate partial signature information for specifying presence or absence of a change to the electronic image information and a changed portion if a change has been made; a registration section 70 that registers the electronic image information and the partial signature information generated from the electronic image information; a storage section 80; and a partial signature verification section 50 that uses the electronic image information and the partial signature information registered by the registration section, to verify presence or absence of the change to the electronic image information, or a changed portion if a change has been made to the electronic image information.

摘要： Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data.At the registration time of new document information, the digital document management program manages a digital signature created in association with document information. At the correction time of the document information, the program acquires partial identification information related to a corrected part of the document information before correction, creates a digital signature to be appended to the corrected document information, and manages the digital signature and partial identification information related to the corrected part of the document information in association with the corrected document information. At the verification time, the program uses partial identification information, the partial identification information corresponding to a corrected part of the document information before correction, and digital signature to perform verification.
