    摘要： A memory system receives data from a host device which requests data write, supplies data to a host device which requests data read, and includes a nonvolatile semiconductor memory and a controller. The memory stores supplied data, and outputs data stored in a designated address. The controller supplies the memory with data in an encrypted form in accordance with a DRM technique employed by a host device which requests data write, and outputs data in an encrypted form in accordance with a DRM technique employed by a host device which requests data read.

    摘要： A method of delivering content data is provided that makes content data able to be reproduced at a user terminal by delivering content key data necessary to decrypt the content data. Specifically, portable storage media storing in advance the content data encrypted with the content key data is connected to the user terminal having a unique terminal ID. User key data that is provided with a predetermined expiration date and is necessary to encrypt the content key data is transmitted from a server to the user terminal. The user key data is stored in an internal memory in the user terminal in such a way that the user key data is unable to be read out of the internal memory. The content key data necessary to decrypt the content data stored in the portable storage media is encrypted with the user key data, and the encrypted content key data is stored in the user terminal or the portable storage media.

    摘要： One aspect of the present invention is to provide a login system and method which can be easily applied to corporate members, and which can prevent unauthorized use even if authentication information is copied. Because of a configuration in which login is carried out by using service right data for each medium identifier of a secure storage medium, unless a dishonest person uses the secure storage medium, it is impossible to log in even if the dishonest person copies authentication information. Further, provided that the secure storage medium is distributed to every signal person belonging to a corporate body, it can be applied to corporate users in the same way as individual users.
