Abstract
An information processing apparatus includes a data processing unit that verifies data recorded on a disk and reproduces content recorded on the disk if a verification condition is satisfied. The data processing unit verifies the validity of an ID inserter that has recorded, on the disk, an ID corresponding to the disk. The data processing unit acquires an ID inserter certificate containing an apparatus ID of the ID inserter that has recorded the ID corresponding to the disk on the disk and an ID inserter blacklist having apparatus IDs of invoked ID inserters registered therein, determines whether the apparatus ID contained in the ID inserter certificate is registered in the ID inserter blacklist so as to verify the validity of the ID inserter that has recorded the ID corresponding to the disk, and stops reproduction of the content if it is determined that the ID inserter is not valid.
