Abstract
Provided is an information processing device including a data processing unit that executes reproduction processing of content recorded in an information recording medium. The content includes an individual segment region formed of a plurality of variation data in which identification information different from each other is embedded and each of which can be decrypted by a different key, and a common segment region formed of single data. The variation data is formed of a 6144 byte aligned unit. The data processing unit calculates a reproduction path by applying a device key held in a memory, and selects an aligned unit corresponding to one variation data that corresponds to the calculated reproduction path from a plurality of aligned units configuring the plurality of variation data in the individual segment region included in the data read from the information recording medium, and then, executes the decryption and reproduction processing.
