Abstract: A method and a system are provided for recognizing a disc. In one example, the system receives a disc, such as, for example, a Blu-ray Disc. The disc includes a content certificate and data files. The content certificate includes a unique text file that certifies the disc complies with predetermined disc parameters. The data files are the actual audio and/or video content on the disc. The system reads the content certificate or reads the data related to the data files. The system generates a hash value by applying a hash function to the content certificate or to the data related to the data files. The hash value is a unique identifier for the disc.
