Title: Right protection method
Inventor: YAMAZAKI IORI
IPC: H04N21/4408
Filed: 2000-12-06
Abstract: PROBLEM TO BE SOLVED: To protect a copyright of contents stored in a storage medium and each right of broadcast enterprises and users. SOLUTION: In order to protect the copyright of contents that is stored in a storage medium and carried and the right of broadcast enterprises and users, a transmitter side encrypts the contents, set its key to meta data, encrypts the meta data by using a different key, and distributes the encrypted contents and the encrypted meta data as a set. A reception terminal decodes first the encrypted meta data in the encrypted contents and the encrypted meta data received by the terminal, acquires the key for the contents, and stores the key to a key table in the reception terminal where the security is secured. Then, the reception terminal again encrypts the meta data by using the key the same as that of the contents and stores the encrypted contents and the encrypted meta data to an HDD.  When viewed contents are selected, the terminal reads the meta data from the HDD, acquires the key from the key table and decodes the meta data. After a view contract, the keys for the contents and the meta data are stored in a personal mobile CA(Conditional Access) module. Then, by using the contents key, the encrypted contents are decodes to allow user to view the contents.
