DATA MANAGEMENT APPARATUS, DATA MANAGEMENT METHOD, AND RECORD MEDIUM RECORDING DATA MANAGEMENT PROGRAM

摘要

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).
