    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： An information processing apparatus includes: a data processor which creates content to be distributed to a client, wherein the data processor executes processing of creating content provided to a client by selecting data in units of segments, which are division data of content, from a plurality of additional information recorded content items obtained by recording different additional information items on original content, selects different segment columns in units of content distribution clients in the processing of creating content provided to a client, and creates management information in which client information for identifying a client of a content distribution destination and segment column information indicating a segment selection state of the content provided to a client, which is provided to a corresponding client, are matched with each other and records the management information in a storage unit.

    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.
