摘要:
The present invention provides a rights management terminal that can securely send and receive usage information while preventing spoofing and protecting user's privacy. The rights management terminal manages a copyright of a content using a license that includes a usage rule of the content, and includes: a first public key certificate management unit which manages, as a set, a first public key certificate that includes identification information for uniquely identifying at least one of the rights management terminal and a user using the terminal, and a first private key paired with a first public key included in the first public key certificate; a second public key certificate management unit which manages, as a set, a second public key certificate that does not include the identification information, and a second private key paired with a second public key included in the second public key certificate; a selection processing unit that selects, as a set, one of the following: the first public key certificate and the first private key; and the second public key certificate and the second private key; and an authentication processing unit that executes authentication for communicating with a server apparatus, using the public key and the private key that are selected as a set by the selection processing unit.
