Next, in steps ST7 and ST8, copy permission and determination of copy conditions are sent to the drive device 11. Next, in step ST8a, the drive device 11
Judges based on the copy permission or the like from the copy control server 80, and if it is not permitted, it stops (step S
T8b), in the case of permission, copying within the permission copy condition is started (step ST9).

Next, in step ST9a of FIG. 18, the drive device 11 starts reading the encrypted content from the optical disc 3 which is the copy source. Next, in step ST9b, the content is decrypted while being read. Specifically, playback-only software having a decryption routine is put in the optical disc 3, and when the content is copied, a predetermined key (name of end user, etc.) is used to perform simple encryption again. You can do it like this. By doing so, a suppressing effect can be expected when a large amount of the content of the optical disc 3 is copied to another recording medium. Next, in step ST9c, it is determined whether or not the content is encrypted when the content is copied to another recording medium which is the copy destination.

On the other hand, if the encryption is not necessary, the process proceeds to step ST9f, and if the encryption is required, the process proceeds to step ST9d. In step ST9d, the copy control server 80 acquires the names of connected devices of the drive device 11 and end users (user names). Next, in step ST9e, for example, the content is encrypted by the connecting device or the like that records the content in the recording medium of the copy destination.

Next, in step ST9f, the drive device 11 starts copying the encrypted content to the connected device as the solar device. Next, in step ST9g, the drive device 11 confirms the completion of copying. Finally, step ST10 shown in FIG.
In a, the copy control server 80 updates the copy record. Specifically, FIG.
11 is updated in the copy history management table 93a of FIG. 11 managed by the copy control database 93 shown in FIG.

According to the embodiments of the present invention, it is possible to manage the duplication of the contents of the optical disc. That is, although illegal copying of contents has been widespread at home in the past, such illegal copying is prevented. In addition, it is possible to perform control so that only a person who has a legitimate copy permission can copy as many as the permitted number.

Further, according to the present embodiment, by allowing a part of the content to be copied as described above, that is, by allowing the customer to copy a simplified version or a demonstration version of the game to a friend, It can be used to promote the sale of contents such as software.

Further, according to the present embodiment, the history at the time of copying can be managed on the customer side, and the copy history of each end user can be tracked, so that the popularity and likability of each content can be improved. Etc., and can be used as future business market information.

Further, according to the present embodiment, even if the master disc is illegally copied before each optical disc 3 manufactured inside the factory 7 is given an identification number, the illegally copied recording medium is used. Since the identification number does not actually exist even after starting to use, it is possible to detect an illegal copy or the like and prevent the content from being stolen.

Further, according to the present embodiment, after the optical disk 3 manufactured in the factory 7 is temporarily taken home by the employee of the factory 7 and the contents are illegally copied and registered, the optical disk 3 is normally processed. Even if the product is sold, since it is discovered that the product is already registered when a legitimate end user purchases it and tries to copy it, it is possible to find fraud in the factory 7.

The present invention is not limited to the above embodiment. The above embodiment can be applied not only to the above embodiment but also to an apparatus having a function of managing a recording medium in which electronic data regarding a literary work is recorded. Further, each of the configurations of the above-described embodiments can be partially omitted or arbitrarily combined so as to be different from the above.

Further, when the identification number is referred to by the identification number management server 9 and the identification number is found to be a properly registered identification number, the identification number management server 9 causes the drive device 11 of the identification number to be identified. To end users of
It goes without saying that, for example, new contents may be introduced and Internet shopping may be proposed. Assuming that the end user has registered the identification number, the registration information of the media information management database 27 of the identification number management server 9 may include information such as the name of the end user. Needless to say.
