摘要:
An information processing apparatus includes a data processor and a storage. The storage is divided into a protected area to which access is limited and a general purpose area which is freely accessible, and configured to store in the general purpose area encrypted content, and an encrypted title key obtained by encrypting a title key to be applied to decrypt the encrypted content, and store in the protected area a binding key applied to encrypt the title key, and a hash value of the encrypted title key. The data processor is configured to determine, in response to a request for access to the protected area from an external apparatus, whether or not to permit the access, and permit, only when access permission determination is made, the access to the protected area.

摘要:
An original data circulation system for storing or circulating original data which is digital information is provided. The original data circulation system includes an issuer apparatus, a user apparatus and a collector apparatus. The issuer apparatus generates originality information including first information corresponding to the issuer apparatus and second information corresponding to data and sends the originality information. The user apparatus verifies the validity of the source apparatus of the originality information and stores the originality information when the validity is verified. The collector apparatus verifies the validity of the source apparatus of the originality information and processes data corresponding to the second information when the validity is verified.

A facsimile apparatus detects whether or not an ink ribbon internally mounted in an ribbon cassette amounted to the facsimile apparatus is a standard ink ribbon. When the apparatus detects a non-standard ink ribbon, the apparatus notifies a user by printing a message informing that the presently-mounted ink ribbon is a non-standard one and that printing function with the presently-mounted ink ribbon will be disabled after elapse of an allowable time.
摘要:
There is provided the present invention to prevent illegal copying of recorded information and enable flexible management of contents, and further facilitate improvement of copy protection technology and the like. A key obtaining module (2) is recorded on a read-only information recording medium (1) to which a copy protection technology is applied. A reproducing module (3) safely obtains a media key unique to the key obtaining module (2) from the key obtaining module (2), generates a content key from the media key, and decrypts an encrypted content (4) using the content key and reproduces the content. In this case, while the key obtaining module (2) needs to be present on the information recording medium (1), the reproducing module (3) and the encrypted content (4) do not need to be present on the information recording medium (1) and may be present outside the information recording medium (1).
摘要:
Disclosed herein is a move component for moving a license describing a usage rule of the content between a plurality of storage components each storing the license in a storage, the move component including: a receiving section for receiving the license from the first storage component that stores license in a first storage; an analyzing section for evaluating the license to allow or prohibit move of the license; and a transferring section for transferring the license to the second storage component that stores the license in a second storage if move of the content is allowable.
