SOLUTION: A data format discriminating unit 103 takes out a distribution content from the outside or a non-encrypted content from a recording medium according to a user's selection. In the case of “CD”, the data registration unit 104 encrypts the content and writes it in the data storage unit 106, reads out the right information from the right management table 102 by data format, and stores the data ID, the encrypted information, the right information, and the file name. The data is written in the data management table 105, and the encryption information and the right information are written in the data storage unit 106.
