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： To realize a configuration to output content to a medium and to use the content stored in the medium under control of the use of content.A content-output-device outputs an encrypted content and an encryption key to be applied to the using process to the medium, and a management server generates a media ID verification value based on a media ID that is an identifier of the medium and transmits the value to the medium. The medium stores the encrypted content, the encryption key, and the media ID verification value in a storage unit. A reproduction device loads the medium and calculates a verification value based on the media ID acquired from the medium, and executes a reproducing process of the encrypted content stored in the medium by data processing to which the encryption key is applied on condition that a matching process performed between the verification value and the media ID verification value stored in the medium is established.

摘要： The present invention enables execution of predetermined content usage control processing without depending on a framework of a content playback program (application). Upon content playback processing, a flag which sets information of determination as to whether or not it is necessary to refer to a management information file such as a token or a usage control information file associated with content is recorded in a content file including encrypted content to be stored in a recording medium. Upon the content playback processing, a playback apparatus acquires the content file including the encrypted content stored in the recording medium, refers to a flag recorded in the content file and determines whether or not it is necessary to refer to the management information file based on a setting of the flag. When the setting of the flag indicates that it is necessary to refer to the management information file, it is possible to select a correct management information file based on a content file identifier as a search key.

摘要： The present invention provides a time setting system and method thereof that are capable of correctly setting time if a delay occurs in the transmission of time information. In the system for setting a master time outputted from a master apparatus to a slave time of a slave apparatus that counts time independently of the master apparatus, the slave apparatus has transmission section for transmitting master time request information to the master apparatus via a network and the master apparatus has an allowable range information acquisition section for acquiring allowable range information indicative of an allowable time in which the master time may be set to the slave time of the slave apparatus and transmission section for transmitting the master time and allowable range information to the slave apparatus. The slave apparatus obtains a time difference between a first slave time to be obtained before or after the transmission of master time request information and a second slave time to be obtained at reception of the master time and the allowable range information. If the allowable time is greater than the obtained time difference, the master time is set.
