摘要： The CPU 11 of the personal computer 1 controls the CPU 32 of the adaptor 26 made of a semiconductor ID to compute a hash value of a content-managing music data base recorded in the HDD 21 and store it into the nonvolatile memory 34. When playing back a content recorded in the HDD 21, the CPU 11 computes the hash value of the music data base recorded in the HDD 21, compares it with hash values stored cumulatively in the nonvolatile memory 34, and controls the playback of the content from the HDD 21 based on the result of the comparison.

摘要： After a reproduction program is installed on a PC, a key for CD ripping is furnished e.g., from an FD. With the key for CD ripping, the music contents in a CD can be copied to a PC, however, it is not possible to download music contents from an EMD server for copying on a PD. For storing the music contents distributed from the EMD server on the PD, the reproduction program first acquired a key for EMD different from the key for ripping over the network. By so doing, the contents data distributed over the network may be improved in safety.

摘要： Even if contents data distributed over a network are once destroyed, the contents data are restored, as the copyright protection is maintained. A PC memorizes backup of distributed music contents on a hard disc, at the same time as it transmits the using log information of the music contents stored in the hard disc to an EMD server. If the music contents in the hard disc are destroyed, the PC acquires the using log information from the EMD server to reproduce the backup data memorized in the hard disc depending on the using log information.

摘要： A contents database 114 memorizes the discriminating information for discriminating contents and the temporal information as to the time of content duplication associated with the discriminating information. A recording program 113 acquires the discriminating information of contents to be duplicated and duplicates the contents in association with the acquired discriminating information and with the temporal information memorized in the contents database 114. This substantially prohibits duplication in large quantities without significantly impairing the interests of a user.
摘要翻译： 内容数据库114存储用于鉴别与识别信息相关联的内容复制时间的内容和时间信息的识别信息。 记录程序113获取要复制的内容的鉴别信息，并与所获取的鉴别信息相关联并与存储在内容数据库114中的时间信息重复内容。 这实质上禁止大量的重复，而不会显着损害用户的兴趣。
