Abstract:
1. An information processing device comprising: a local memory unit programmed to store data including first encrypted content; a memory programmed to store data including key information to be used in a process of reproducing the first encrypted content; and a data processing unit programmed to selectively reproduce second encrypted content stored in a disk or the first encrypted content stored on the local memory unit and select one of a first medium ID and a second medium ID to be read based on which one of the first encrypted content or the second encrypted is to be reproduced, wherein, in reproducing the second encrypted content, the data processing unit is programmed to read the second medium ID from the disk and, in reproducing the first encrypted content, the data processing unit reads the first medium ID from the memory, wherein the data processing unit is programmed to read the first and second medium ID by executing a single application programming interface (API), which defines a first medium ID acquiring process sequence for reading the first medium ID and a second medium ID acquiring process for reading the second medium ID, and wherein the data processing unit is programmed to selectively reproduce the first or second encrypted content by transmitting to a management server the read first or second medium ID and a content ID of one of the first and second encrypted content and receive, from the management server, one or more permitted processes corresponding to the transmitted first or second medium ID and the one of the first and second encrypted content.
