摘要： A data transmission apparatus, a data reception apparatus, and a data transfer system prevent a case where same usable data is present in plural apparatuses at the same time and can certainly move data, in MOVE processing of the data between the data transmission apparatus and the data reception apparatus. The data transmission apparatus includes a synchronous control unit synchronizing a timing of (i) deleting or invalidating, in the data transmission apparatus, move-target data and (ii) decrypting, in the data reception apparatus, the move-target data that has been encrypted. With this, it becomes possible to prevent a case where the same usable data is present in plural apparatuses at the same time.

摘要： An AV data transmission apparatus includes an encryption unit which encrypts AV data, an AV data transmission unit which transmits the encrypted AV data, a cipher-type-information switching unit which switches cipher type information indicating a cipher scheme used for the AV data, to other cipher type information, and a cipher-type-information transmission unit which transmits cipher type information. When transmitting AV data which is prohibited from being used in a reception apparatus that does not support new usage control information, the AV data transmission apparatus assigns different cipher type information, which is used to notify the reception apparatus, so that even the reception apparatus which cannot recognize the new usage control information can recognize its inability to perform decryption is due to new encryption performed by the AV data transmission apparatus.

摘要： A data transmission and reception system and the like are provided, which are capable of preventing: unauthorized copying between a server and a client; and unnecessary use limit when a copyright constraint is conformed. A server generates and manages overall use permission information indicating that the overall data accumulated in the server can be used and distributes the overall use permission information together with copied data to the client determined to exist within a private use range. The client manages the overall use permission information and the data received from the server in such a manner associated with each other and enables use of the data received from the server only when the overall use permission information is valid. When the client moves only within the private use range, the server continuously manages the overall use permission information so as to enables use of the copied data. Meanwhile, use of the copied data in the client which has moved out of the private use range is inhibited.

摘要： A portable terminal (2) is a data transmission and reception control apparatus. A Proximity confirmation unit (23) confirms a first proximity condition of proximity to the data transmission apparatus. A proximity apparatus authentication and registration processing unit (21) registers the portable terminal (2) into the data transmission apparatus when authentication in conjunction with the data transmission apparatus is successful, and the first proximity condition is satisfied. A proximity confirmation unit (27) confirms a second proximity condition of proximity to the data reception apparatus. A registration starting and authentication processing unit (26) obtains identification information of the data reception apparatus when authentication in conjunction with the data reception apparatus is successful, and when the second proximity condition is satisfied. An authentication and registration processing unit (22) registers the identification information of the data reception apparatus into the data transmission apparatus when authentication in conjunction with the data transmission apparatus is successful.
