    摘要: A personal computer PC transmits to a server encoded user information and encoded license information, etc. contained in a secure recording medium. The server decodes the encoded license information to obtain license information. Then, the server deletes the encoded license information contained in the secure recording medium via the personal computer PC. The server decodes the decoded user information contained in a secure recording medium to obtain user information. Then, the server encodes the license information based on the user information to write the obtained encoded license information into the secure recording medium via the personal computer PC. In this manner, license information can be moved between two secure media and convenience can be improved.

    摘要: A present invention is related to a management apparatus for a content distribution system, a browsing apparatus, a program and a method for further facilitating a distribution of content. A management apparatus comprises a function of managing a content ID indicating encrypted content information, a content ID indicating a user and a group of a distributor ID indicating a distribution agent or a distribution user of the content information and a function of transmit ting key information when receiving a transmission request including key price information equivalent to key price or key price paid information and each ID. Therefore, since a distribution route is specified only by the distributor ID different from conventional distribution information, the distribution system can be simplified.

    摘要: To reduce a load on a user terminal imposed when verifying signature data and at the same time reduce a load on a server, a signature key matrix KM includes a plurality of signature keys Ki-j arranged in a matrix structure of m rows and n columns, and is stored in a signature key matrix database 21. A correspondence relationship between a signature key set CK which is an aggregate of any signature keys selected from the n columns respectively and a user terminal 30 is stored in a correspondence relationship information database 22. A signature data generating unit 24 generates signature data having a matrix structure by encrypting a content digest D generated based on content data C by n number of signature keys included in the signature key matrix KM.
