Information processing device, information processing method, and computer program

Abstract

A structure for preventing information leakage and content false processing during content utilization involving data transfer between different devices. During content reproduction or recording involving data transfer between different device such as a drive and a host, a medium ID (disk ID) used for encrypting or decrypting a content is read out of a medium, and the drive checks if the medium ID is recorded according to a header code preset for the authenticated medium. If it is confirmed that the medium is an authenticated one, the drive encrypts the medium ID and output it to a host. With this, leakage to the outside of a medium ID and reproduction or recording of a content using a false medium can be prevented.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a computer program. More specifically, the present invention relates to an information processing apparatus having a configuration preventing unauthorized use of content, an information processing method used therewith, and a computer program used therewith. Background technique [0002] In recent years, information recording media capable of storing large amounts of data, such as DVDs or Blu-ray discs (Blu-ray discs), have become popular. For example, digital content such as high-precision image data or high-quality audio data recorded on or reproduced from a recording medium such as a disc has come into common use. [0003] According to the digital recording device and recording medium, images and audios can be repeatedly recorded and reproduced without lowering their quality. Therefore, the distribution of illegally copied contents via the Inte...

Problems solved by technology

[0005] For example, when data is to be transferred between a drive and a host, there is a problem that leakage of content, key information, and other secret information may occur, with the result that the possibility of unauthorized use and leakage of content increases

Problems can also occur as encrypted content of legitimate records is read and converted to plain text and copied by user-created software
