The data type identification unit 103 obtains a circulation content from an external source or obtains a not encrypted content from a record medium. When the obtained content has the CD type, the data registration unit 104 encrypts the obtained content and writes the encrypted content to the data storage unit 106. The data registration unit 104 obtains the rights information from the rights management table 102, writes the data ID, encryption information, rights information, and file name to the data management table 105, and writes the encryption information and the rights information to the data storage unit 106. When the obtained content is a circulation content, the data registration unit 104 writes the circulation content to the data storage unit 106, and writes the data ID, encryption information, rights information, and file name to the data management table 105. <IMAGE> |
