Information processing device, contents distribution server, license server, and method and computer program
First Claim
1. An information processing device serving as a contents playing device that plays contents, said information processing device comprising:
- a communication unit configured to execute communication processing with a license storage device storing rights information serving as usage rights information of contents associated with a user of the information processing device, and communication processing with a contents distribution server;
an encryption processing unit configured to execute encryption processing including authentication processing in said communication processing; and
a control unit configured to execute processing control for inputting rights information corresponding to contents from said license storage device, via said communication unit, to transmit said input rights information, which indicates rights to receive streaming contents, to said contents distribution server, to receive streaming contents corresponding to said rights information from said contents distribution server, and to play said streaming contents,wherein the control unit is configured to perform, subsequent to a beginning of playing of said streaming contents by said information processing device serving as the contents playing device, subsequent authentication processing with the license storage device while the playing of the streaming contents is occurring, and is configured to stop the playing of said streaming contents when the subsequent authentication processing with the license storage device fails, said subsequent authentication at least confirming that the license storage device remains in communication with the information processing device serving as the contents playing device while the playing of the streaming contents is occurring.

Abstract
Usage rights information indicating a license which is usage rights corresponding to contents is stored in a license storage device, and at the time of using the contents, the rights information is output from the license storage device to a contents using device and further transmitted to a contents distribution server, and legitimacy verification of the rights information is executed at the contents distribution server, such that contents corresponding to the rights information are transmitted to the contents using device. Thus, a device and method is realized whereby distribution of contents over a network and use thereof is enabled without detracting from safety and user convenience.
