摘要 |
The present invention enables management of the copyright of content to which identification information is not added. An arithmetical unit 206 computes a hash value based on the data of a portion of content data recorded in an MD 209, and transmits the value from an input/output unit 201 to a personal computer. Based on the hash value, the personal computer identifies the content recorded in the MD 209, and performs management based on the display information of check-in and check-out of the content. The present invention can be applied to personal computers. <IMAGE> |
