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 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： A computer-readable recording medium storing an access rights management program which is capable of safely managing the use of an electronic document with ease and efficiency. An access policy-storing device stores a first access policy containing information on a first distributee to which the electronic document is distributed, and information on second distributees, which is indicative of a range within which the first distributes is permitted to distribute the electronic document, as well as information on use rights that permit the second distributees to use the electronic document with a defined scope of authority. A storage device stores a distribution target indicative of the second distributees. When a distributes specifying request for permission to grant the use rights to a specific distributes is received from the first distributee, an access policy-confirming device refers to the distribution target to confirm whether or not the specific distributes is included in the second distributees. A registration device registers a second access policy associating the specific distributes with the information on the use rights, in said access policy-storing device. A use rights-confirming device refers to the second access policy to thereby permit the specific distributes to use the electronic document using the use rights, when a use request for permission of use of the electronic document is received from the specific distributes.
