The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program for importing and exporting a content with information missing controlled. A CPU extracts a sound track contained in the content in step S, and converts a format of the extracted sound track into a format compatible with a memory stick in step S. The CPU generates a predetermined file from data contained in the content and excluding the sound track in step S. In step S, the CPU attaches reference information of the sound track to the file. In step S, the CPU controls the writing of the sound track in the converted format and the file to the memory stick. The present invention is applied to clients of a DRM system.

Information processing apparatus, information processing method, recording medium, and program

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.

Information processing system

The present invention relates to an information managing apparatus and method, a recording medium, and a program in which unauthorized use of content can be prevented. A ripping moduleof a clientretrieves the content recorded on a CD. In the client, a content ID for identifying the content and a unique ID unique to the clientare generated, and these IDs are added to the content retrieved by the ripping module. A usage right containing the usage conditions of the content, etc., is generated and saved. The usage right includes information indicating that an apparatus (client) having the same ID to the unique ID added to the content is only allowed to play back the content. The present invention is applicable to an information processing apparatus such as a personal computer.

Information managing apparatus and method, recording medium, and program

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.

Contents furnishing system

There is provided a processing apparatus which increments and thereby restores a lendable number upon receiving a content returned from a portable device, and which confirms the return of the content and increments the lendable number even when the portable device does not have or deletes the content borrowed from the processing apparatus before returning the content.

Information-processing device, information-processing method, recording medium, and program

There is provided a personal computer which increments and thereby restores a lendable number upon receiving a content returned from a portable device, and which confirms the return of the content and increments the lendable number even when the portable device does not have or deletes the content borrowed from the personal computer before returning the content.

An information processing apparatus is provided including a memory configured to store content data and corresponding content management information. The content management information defines a rule set relative to reproduction of the content data. The content data and management data are embodied in a first format. A processor is configured to convert the first format of the content management information into a second format, different from the first format. A transmitter is provided to transmit the second format of the content management information to another information processing apparatus.

Information processing apparatus and method, and program storage medium

The CPUof the personal computercontrols the CPUof the adaptormade of a semiconductor ID to compute a hash value of a content-managing music data base recorded in the HDDand store it into the nonvolatile memory. When playing back a content recorded in the HDD, the CPUcomputes the hash value of the music data base recorded in the HDD, compares it with hash values stored cumulatively in the nonvolatile memory, and controls the playback of the content from the HDDbased on the result of the comparison.

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.

Information processing device and method, and program storage medium

A contents databasememorizes the discriminating information for discriminating contents and the temporal information as to the time of content duplication associated with the discriminating information. A recording programacquires 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. This substantially prohibits duplication in large quantities without significantly impairing the interests of a user.
