摘要: A system is provided for preventing recorded data from being illicitly read out and analyzed. An Internet connection interface transmits a program executed by an adapter to an authentication station, while receiving the program in an encrypted form from the authentication station. A hard disc records the encrypted program, received from the authentication station. An interface transmits the program recorded on the horizontal direction on the adapter.

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.
摘要翻译: 在PC上安装了再现程序之后,例如从FD提供用于CD翻录的键。 使用CD翻录的键,CD中的音乐内容可以复制到PC,但是,不可能从EMD服务器下载音乐内容以在PD上进行复制。 为了将从EMD服务器分发的音乐内容存储在PD上,再现程序首先获得与用于通过网络翻录的键不同的EMD的密钥。 通过这样做,可以提高网络上分发的内容数据的安全性。

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.
摘要翻译: 即使通过网络分发的内容数据一旦被破坏,内容数据就被恢复,因为维护了版权保护。 在将硬盘中存储的音乐内容的使用日志信息发送到EMD服务器的同时,PC在硬盘上记录分布式音乐内容的备份。 如果硬盘中的音乐内容被破坏,则PC从EMD服务器获取使用的日志信息,以根据使用的日志信息再现存储在硬盘中的备份数据。

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.
