Abstract

The invention relates to an information processing apparatus, an information processing method and a program. The information processing apparatus includes: a data processing section reproducing contents stored in a medium having a general purpose area in which encrypted contents and utilization controlling information corresponding to the contents are stored, and a protected area configured from a plurality of blocks to which access limitation is set and which include a block in which an encryption key for decrypting the contents and information of a plurality of validity periods indicative of content utilization permission periods applied to the application contents of the encryption key are stored, wherein the data processing section acquires the utilization controlling information of a reproduction object content, extracts selection information of validity period information to be applied to the content, and decides whether or not content reproduction is to be permitted by comparison between the validity period information selected from within the block and current date information in accordance with the selection information.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a program, and more particularly, to an information processing device, an information processing method, and a program that control the use of content recorded on a recording medium such as a memory card. Background technique [0002] Recently, various media such as DVD (Digital Versatile Disc), Blu-ray Disc (registered trademark), and flash memory are used as information recording media. Especially in recent years, memory cards in which a flash memory having a large storage capacity is built are widely used. A user can record content such as music or movies into such various information recording media, and can load the medium into a reproduction device or player to reproduce the content. [0003] However, with many contents such as music data and image data, copyrights, distribution rights, etc. are owned by content creators or content sellers. ...
