    摘要： It is an object of the present invention is to provide a disk unit capable of restricting access to data stored in the recording medium depending on users. The user enters a password into a host computer 100. This password is transferred to a password verification section 20. Then, the password verification section 20 checks whether the password coincides with any one of authentication passwords 11 through 13 stored in an authentication password storage section 10. If the password coincides with any one of the passwords, the password verification section 20 supplies an authentication signal to an operation mode control section 30. The operation mode control section 30 supplies an operation mode signal to a controller 50 by receiving the authentication signal. The controller 50 controls execution of the operation mode according to the operation mode signal.

    摘要： A content access control system comprising: a read unit (810) which reads out content (802) and license information (801) from a medium (800) where the content to be provided from an authenticated information provider to a user and the license information regarding access to the content are recorded in correlation with each other; a transfer unit (824) which transfers the read-out content and license information; a reception unit (924) which receives the read-out content and license information; and a write unit (910) which generates the content and the license information from the read-out content and license information received by the reception unit, and writes the generated content and license information onto another medium (900); characterized in that: the transfer unit (824) transfers the read-out content (802) and license information (801) as a file; the reception unit (924) receives the file; the write unit (910) generates the contents and the license information from the file, items of identifying information being allocated to two or more of the read unit (810), transfer unit (824), reception unit (924) and write unit (910), respectively; the license information (242) recorded in the medium (240) includes two or more blocks of license information each of which includes a respective item of said identifying information; the blocks of license information are subjected to multiple encryption by setting a logical product of the identifying information included in the blocks of license information; and the system allows access to the content (802) only when the decrypted license information satisfies the logical product.

    摘要： The object of the present invention is to provide a contents data utilization system in which the contents data is shared between a plurality of mobile communication terminals (1) while the copyright is protected. When the contents data downloaded via a communication network is stored into an external memory (4) of a mobile communication terminal (1), a cipher key generating unit generates a cipher key, using the fingerprint intrinsic to the user of the terminal. Using the cipher key, a contents data processing unit (13) encodes the downloaded contents data, and stores it into the external memory (4). When the contents data is reproduced, the cipher key generating unit generates a cipher key, using the fingerprint intrinsic to the user of the terminal, and decodes and reproduces the contents data stored in the external memory (4). Thereby, the contents data can be shared between a plurality of mobile communication terminals (1) owned by the user.
