Abstract
A method for identifying the contents of a compact disc manipulating a received table of contents (TOC) identifier associated with the compact disc. The method parses portions of the TOC comprising a series of numbers corresponding to track offsets for each track of the compact disc. The method further determines the first number from the series of numbers, subtracts the first number from each number in the series of numbers to form an altered series of numbers, and concatenates the altered series of numbers to form an altered string that comprises the altered TOC identifier. The altered TOC identifier may then be compared to a plurality of canonical TOC identifiers to identify the contents of the compact disc. Another method generates a generic TOC identifier for a plurality of compact discs known to contain the same data.
