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.

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： 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： 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.
