PROBLEM TO BE SOLVED: To provide a configuration capable of limiting a data processor to utilize contents. SOLUTION: As a reproduction execution condition of contents stored on a removable storage device such as memory card, the device can acquire a contents key, which can be decoded by effective key block(EKB) processing. Further, the device performs recording processing to the removable storage device or the device designated in the case of contents purchasing processing can be set. Thus, even when a plurality of devices capable of decoding the same EKB exist, a device capable of reproducing the contents stored on the removable storage device can be limited to only one device. |
