An information processing apparatus includes a data processor configured to obtain first content stored in a first information recording medium and second content which is stored in a second information recording medium and which is usable together with the first content, and to perform content playback processing by using the first content and the second content. The data processor calculates a hash value of a certificate stored in the first information recording medium, and verifies the calculated hash value against a hash value stored in a content certificate corresponding to the first content, and on the condition that the calculated hash value and the hash value stored in the content certificate coincide with each other, the data processor performs the content playback processing by using the first content and the second content.
