摘要： A configuration for achieving efficient content verification processing based on hash values is provided. Hash values of hash units set as segmented data of a content stored on an information storage medium are recorded in a content hash table and are stored on the information storage medium together with the content. An information processing apparatus for executing content playback executes hash-value comparison processing based on one or more randomly selected hash values. Regardless of the data amount of content, the configuration can perform hash-value determination and comparison processing based on hash units having a small amount of data, so that user equipment for executing content playback can perform efficient content verification.

摘要： A configuration is provided which improves scrambling processing of content and eliminates unauthorized use of content. Scramble rules which differ for each content are used for content scrambling processing. For example, in the event of using shuffling processing, various shuffle states are specified as scramble rules. In the event of using Exclusive-OR processing, a value applicable to EXOR is specified as the scramble rule. Also, in the event of using rotation processing, a shift amount is specified as the scramble rule. In the event of using 32 shuffle elements in shuffling processing, 32! different shuffle states, that is to say, 32! different scramble rules can be specified. Also, the values for EXOR or the rotation shift amount can be set as various values, and many scramble rules can be set.
