摘要： Processing load on an executing device for conducting playback is high during the playback of contents since the executing device performs verification of the contents validity in parallel with the contents playback, and therefore the executing device has to be equipped with a highly efficient processor. The present invention reduces the processing load involved in the verification by using, for the verification, only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on the DVD. In addition, the present invention is capable of improving the accuracy of detecting unauthorized contents to some extent by randomly selecting a predetermined number of encrypted units every time the verification is performed.
摘要翻译：由于执行装置与内容重放并行地执行内容有效性的验证，所以在内容的重放期间，用于进行再现的执行装置上的处理负载很高，因此执行装置必须配备高效率的处理器。本发明通过仅使用构成在DVD上记录的加密内容的多个加密单元随机选择的预定数量的加密单元来验证验证。此外，本发明能够通过每次执行验证时随机选择预定数量的加密单元，来在一定程度上提高检测未授权内容的准确性。

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.
摘要翻译：为了提供能够根据DRM保护内容的内容回放设备，当解密记录在记录介质上的加密内容并播放解密的内容时。如果密钥生成信息是“00”，则密钥控制单元104依次连接解密的媒体密钥和内容信息，并且向连接结果应用单向函数以生成内容密钥。如果密钥生成信息是“10”，则密钥控制单元104设置权限密钥作为内容密钥。如果密钥生成信息为“01”，则密钥控制单元104依次连接解密的媒体密钥和权限密钥，并将单向功能应用于连接结果以生成内容密钥。

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： Provided is a new system for content use and settlement. A user requests a mobile telephone charge management server (3000) to perform proxy settlement for goods purchased using mobile telephones 1 (4100), 2 (4200) and 3 (4300). The mobile telephone charge management server (3000) makes an inquiry to a registration server (3100) as to whether or not proxy settlement is possible. When proxy settlement is not possible, the mobile telephone performs settlement using electronic money that has been deposited therein.
