    摘要: A digital document management system is capable of guaranteeing that a partial correction has been made according to a proper procedure and achieving a third-party certification of the validity of the guarantee. The digital document management system manages document information created in a digital form, and includes partial identification information generation section that generates partial identification information that represents, in an identifiable manner, respective parts of the document information. A partial correction information generation section generates partial correction information which is information related to a correction history of a corrected part in the case where any correction has been required for the document information; and an original document information management section manages the document information, partial identification information, partial correction information, and prescribed policy information in an associated manner.

    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: A first access policy is stored to provide information on a first distributee to which an electronic document is distributed, to which the first distributee is permitted to distribute the electronic document, and use rights that permit the second distributees to use the electronic document. Also stored is a distribution target information indicating the second distributees. When the first distributee requests permission to grant use rights to a specific distributee, the distribution target is consulted to confirm whether or not the specific distributee is included in the second distributees. A second access policy associating the specific distributee with the information on the use rights is then registered. When the specific distributee requests permission to use the electronic document, the second access policy is consulted to permit the specific distributee to use the electronic document.

    摘要: A computer program, apparatus, and method for managing access to documents, capable of identifying the exact events of document access on the basis of given access logs even when access policies are modified in the middle of operations. Upon receipt of an access policy setup request from a first client, an access policy manager adds a new access policy to the access policy database or modifies an existing access policy in an access policy database according to the request. A policy log collector then stores the records of such a new access policy or modified existing access policy in a policy log database. Afterwards an access log collector receives an access log for the document 5 from the second client 3 and saves it in the access log database 1c. When a third client issues a log request with a specific search keyword, a log searcher retrieves relevant policy log records and access log records that match with the specified search keyword.

    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: 401 stores, in 302, key d′ obtained by subtracting random number 2r held in 201 from key d held in 105. When an operation starts, the values “−C” and “−C2” are calculated respectively, and the resultant values are stored in a multiplication table memory 205 together with value “C”. In a first operation cycle, 107 selects and outputs an intermediate value 108 held in an in-operation data register 103, and thereby makes a modular-multiplication operation circuit 104 perform squaring. In the second operation cycle, 107 selects and outputs one of three values held in 205 in accordance with the combination of key bit value d′i and random number bit value ri, and thereby makes the modular-multiplication operation circuit 104 perform multiplication. Thereby, a cryptographic processing device that requires a short operation time period, small circuit scale, and has sufficient security can be realized.
