Abstract

An information processing apparatus is provided. The information processing apparatus includes content verification means for executing a verification processing of a recording content recorded on an information recording medium, and content play means for executing a content play processing on a condition that validity of the recording content is checked on the basis of the verification processing. The content verification means acquires from the information recording medium a content hash table having registered therein hash values generated on the basis of legal recording content data and executes a processing for verifying a presence or absence of an illegal recording content whose hash value is not registered in the content hash table.

Description

technical field [0001] The present invention relates to an information processing device, an information recording medium, an apparatus and method for manufacturing an information recording medium, and a computer program. More specifically, the present invention relates to an information processing apparatus, an information recording medium, an apparatus and method for manufacturing an information recording medium, and a computer program that can perform authentication processing on various contents requiring content usage management and prevent illegal use of the contents. Background technique [0002] For example, audio data such as music, image data such as movies, game programs and various software data of various applications (hereinafter referred to as 'content') can be stored in recording media such as blu -ray Disc (trademark), DVD (Digital Versatile Disc), MD (MiniDisc) and CD (Compact Disc). In particular, a blu-ray disc (trademark) using a blue laser is a high-de...
