Abstract: A terminal apparatus acquires setting information for controlling whether a storage area held by the non-volatile storage medium is to be used or not, from an external apparatus connected via a network, when the terminal apparatus is activated. The terminal apparatus updates area definition information defining the structure of storage areas in the non-volatile storage medium so that the storage area the use of which is restricted is in a state which cannot be recognized by the operating system, if the acquired setting information indicates that the use of the storage area is restricted. The terminal apparatus performs activation processing of the operating system after the update processing of the area definition information ends, if the acquired setting information indicates that the use of the storage area is restricted.

Abstract: There are provided an information processing apparatus and a license distribution system including the information processing apparatus in which the reproduction or duplication of a content can be limited to the interior of a domain and a benefit based on the fact that an external device has participated in the domain can be made available at the time of reissuing a license. A reproducing device 1 transmits a request for reissuing the license for permitting the reproduction of the content in the domain, and participation information (S201). A server 2 receives the request for reissuing the license and the participation information (S202), and confirms validity of the transmitted participation information (S203). When the validity of the participation information is confirmed, the server 2 determines information on a specific privilege related to the license, transmits the information to the external device (S206), and reissues the license (S210).

Abstract: An information processing apparatus has: a memory 13; CPU for executing a program written in the memory 13; a secure module 20; and storage means for storing a plurality of encrypted programs into which a program is divided. The CPU transmits the program stored in the storage means to the secure module 20. The secure module 20 has: means for receiving the program stored in the storage means, means for returning the received program to an executable state; means for writing the program, which has been returned to the executable state, in the memory 13 in a sequence for CPU to execute, and means for deleting the program from the memory 13 by CPU after execution is completed. When executing the program, the information processing apparatus can make reverse analysis by a malicious third party difficult, and enhance security of a load module to be executed.
