BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to a data processing technology, and more particularly to a technology for reproducing electronic content stored in a recording medium.

2. Description of the Related Art

Recent years have seen widespread use of terminal apparatuses, each provided with a drive for reading data from a recording medium, which processes electronic content stored in the recording media. The terminal apparatus, which is a game device, for instance, reads out a game application (hereinafter referred to as “game AP” also) recorded optically or magnetically in a recording medium such as DVD.

A technology of digital rights management (DRM) is introduced to prevent the electronic content from being used unlimitedly.

Typically, DRM is a technology for the prevention of the unlimited copy of electronic content. To this end, the inventor recognized that there are cases where it is difficult to suitably restrict the use of electronic content, stored in the recording medium like DVD and commercially traded, according to the attributes of use entities of the electronic content.

SUMMARY OF THE INVENTION
The present invention has been made in view of the aforementioned problems, and the main purpose thereof is to provide a technology for restricting the use of electronic content store in a recording medium according to the use entities of the electronic content.

In order to resolve the above-described problems, an electronic content processing system according to one embodiment of the present invention includes: a use permission apparatus provided for use in a recording medium that stores electronic content for a user of the electronic content; a medium drive configured to read the electronic content from the recording medium; and a reproduction device configured to reproduce the electronic content read by the medium drive. The medium drive has a security management unit configured to read from the recording medium an article ID that is an ID of the electronic content or the recording medium. The reproduction device has a security management unit configured to convey a reproduction entity ID, which is a reproduction device ID or a user ID, together with the article ID read by the medium drive to the use permission apparatus when the electronic content is to be reproduced. The use permission apparatus includes: a use condition storage for storing a use condition that defines an attribute of an entity accessible to the electronic content; and a determining unit for determining whether or not a combination of the article ID and the reproduction entity ID conveyed from the reproduction device fulfills the use condition. The security management unit of the reproduction device determines a reproduction mode of the electronic content based on a decision result as to whether or not the combination thereof fulfills the use condition.

Another embodiment of the present invention relates also to an electronic content processing system. The electronic content processing system includes: a use permission apparatus provided for use in a recording medium that stores electronic content for a user of the electronic content; and a reproduction device configured to reproduce the electronic content stored in the recording medium. The reproduction device has a security management unit configured to convey a reproduction entity ID, which is a reproduction device ID or a user ID, when the electronic content is to be reproduced. The use permission apparatus includes: a use condition storage for storing a use condition that defines an attribute of an entity accessible to the electronic content; and a determining unit for determining whether or not the reproduction ID conveyed from the reproduction device fulfills the use condition. The security management unit of the reproduction device determines a reproduction mode of the electronic content based on a decision result as to whether or not the reproduction entity ID fulfills the use condition.

Still another embodiment of the present invention relates to a use permission apparatus. The user permission apparatus is an apparatus provided for use in a recording medium that stores electronic content for a use of electronic content, and the use permission apparatus includes: a use condition storage configured to store a use condition that defines an attribute of an entity accessible to the electronic content; a receiving unit configured to receive an ID of a reproduction entity ID, which is a reproduction device ID or a user ID, from the reproduction device that reproduces the electronic content stored in the recording medium; a determining unit configured to determine whether the reproduction entity ID conveyed from the reproduction device fulfills the use condition or not; and a conveying unit configured to convey a decision result, regarding whether the reproduction entity ID fulfills the use condition or not, to the reproduction device.

Still another embodiment of the present invention relates to an electronic content processing method. The method includes: conveying a reproduction entity ID, which is a reproduction device ID or a user ID, from a reproduction device, which is to reproduce electronic content stored in a recording medium, to a use permission apparatus provided for use in the recording medium for a user of the electronic content; determining whether the reproduction entity ID conveyed from the reproduction device fulfills a use condition or not, wherein the determining is performed by the user permission apparatus that references a use condition that defines an attribute of an entity accessible to the electronic content stored in a predetermined storage area; and determining a reproduction mode of the electronic content according to a decision result regarding whether the reproduction entity ID fulfills the use condition or not.

Still another embodiment of the present invention relates to a package of electronic content available in a commercial transaction. The package of electronic content includes and is supplied with: a recording medium storing the electronic content; a use permission apparatus configured to store a use condition of the electronic content and configured to determine whether the use condition is fulfilled or not, when an instruction is given to reproduce the electronic content from an external reproduction device.

Optional combinations of the aforementioned constituting elements, and implementations of the invention in the form of apparatuses, methods, systems, computer programs, recording media that store the programs, and so forth may also be effective as additional modes of the present invention.

Sony spoke about the possibility to block pre owned games sales, several months before the PS3 was released, nothing happened then, so this patent might never actually amount to anythin.
