摘要： A terminal apparatus performs update processing for a content prior to playback of the content when the content is of a high value. The terminal apparatus sets an allowed time and predicts a required time prior to update processing in advance. For a content being of a low value, the terminal apparatus immediately performs the update processing when the predicted required time is within the allowed time, and when the predicted required time exceeds the allowed time, performs the update processing after ending of usage of the computer program by a user.

摘要： To provide a content playback device capable of protecting content according to DRM, when decrypting encrypted content recorded on a recording medium and playing the decrypted content. If key generation information is “00”, a key control unit 104 concatenates a decrypted media key and content information in this order, and applies a one-way function to the concatenation result to generate a content key. If the key generation information is “10”, the key control unit 104 sets a rights key as the content key. If the key generation information is “01”, the key control unit 104 concatenates the decrypted media key and the rights key in this order, and applies a one-way function to the concatenation result to generate the content key.

摘要： To provide a content playback device that can use content appropriately by avoiding output of content not permitted to be used according to contract information. A playback control unit 102 extracts a content name from playback control information in a playback path information table 210, and inquires of a rights management unit 108 whether content identified by the extracted content name is playable or not. If the content is judged as being unplayable, the playback control unit 102 extracts an alternative playback number from the playback control information, and extracts a content name from playback control information whose playback number matches the alternative playback number. The playback control unit 102 then instructs a decryption unit 103 and a playback unit 107 to decrypt and play back encrypted content identified by the extracted content name.

摘要： A medication history management apparatus enables a person to check for side-effects caused by combinations of drugs, and duplicated administration of drugs, when purchasing non-prescription drugs, even without medical knowledge. The medical history management apparatus securely stores medication history information identifying drugs taken in the past and drugs prescribed in the past in a secure storage unit 403, and stores mutual effect information that shows side-effects caused by combinations of drugs. The medical history management apparatus receives input information identifying a drug from a keypad, judges whether the set of the input information and the any of the drug history information match the any of the mutual effect information, and outputs a judgment result.

摘要： A value holding system includes a receiving unit that receives an instruction to add or remove a value relating to a payment, a judging unit that judges whether the instruction is identical to a previously received instruction, and a rejecting unit that rejects the instruction when the judging unit judges that the instruction is identical to the previous instruction. According to the value holding system so constructed, it is possible to reject an invalid payment request in order to prevent an incorrect collection of payment.

摘要： A data protection system includes terminals, and an encryption device that encrypts distribution data distributed to each terminal. Each terminal corresponds with one node on a lowest level of a tree structure having hierarchies. A data protection system excludes nodes on the lowest level, determines a plurality of combination patterns that include combinations of two or more of all four nodes that are reached one level below the node, decides an individual decryption key for each determined combination pattern, and decides an individual decryption key for each node on the lowest level. The data protection system prescribes nodes that are reached from the node on the lowest level and a terminal to the node on the highest level that is an invalid node. For invalid nodes, the data protection system designates an encryption key that corresponds to the decryption key determined in correspondence with the combination pattern that combines all nodes, excluding invalid nodes, and encrypts distribution data that uses each of the designated encryption keys.
