摘要

PROBLEM TO BE SOLVED: To obtain the contents managing method which limits the duplication of contents and protects the copyright of the contents by checking out from the number of contents which can be copied each time duplicate contents are recorded on a storage medium when an indication for duplicate recording to the storage medium is received. SOLUTION: An LCM 1 is equipped with a secure contents server(SMS) 2 and contents are stored on an SMS 2. The SMS 2 outputs contents data to media (MC) 13. The SMS 2 subtracts '1' from the rest number of contents of checkout requests of a hotel book and erases information stored in areas corresponding to the folders of the contents on the MC 13 by overwriting random numbers. Then the SMS 2 receives the values of the respective areas after overwriting transferred from the MC 13 so as to confirm the overwriting erasure and checks them. Consequently, the number of duplicate contents is efficiently restricted to protect the copyright of the contents.
