摘要： The present invention provides a method, system and program product for modifying content usage conditions during broadcast content distribution. Specifically, the present invention allows protected (e.g., encrypted, secured, etc.) content to be received along with content usage conditions, an encrypted combination of the content usage conditions and a title key (e.g., a MAC), and a key management block. Using the key management block, a key encrypting key can be determined for decrypting the combination. Once the combination is decrypted, the content usage conditions can be modified (e.g., edited, added to, etc.).

摘要： A method and system for generating data for generating an authenticity certificate to be stored on a media. The authenticity certificate authenticates an object. A request for a step certificate includes a media identifier, a media key block, an object identifier, a requester entity type, and a requester identity certificate. The object identifier is hashed. A created signature includes the hashed object identifier, the requester entity type, a certifier identity certificate, and the requester identity certificate. A generated hashing result is a concatenation of the object identifier, the requester entity type, the certifier entity certificate, the requester identity certificate, and the signature. The step certificate including the hashing result is generated and encrypted. The encrypted step certificate and an encrypted random key are sent to a requester of the step certificate. The object may be determined to be an authentic object, a counterfeited object, or a stolen object.

摘要： An information processing apparatus includes: a memory in which an apparatus-unique key is stored, the apparatus-unique key being a key that is unique to the information processing apparatus; an input section that inputs user operation information; a communication section that performs data reception processing; a data processor that executes validity determination processing for the apparatus-unique key; and an output section that outputs a result of the validity determination processing executed by the data processor. The data processor receives, via the communication section, key-validity determination data for determining whether the apparatus-unique key is valid or invalid. The data processor also executes the apparatus-unique-key validity determination processing by using the key-validity determination data in response to a user instruction input via the input section, and outputs a result of the validity determination processing to the output section.
