Abstract
For possible use in an electronic content distribution system, automatic recognition of compact discs or other storage media containing particular content, and corresponding account crediting is described. In an electronic content distribution system, such as those providing music available by digital downloading or streaming technologies, a user may ordinarily pay a full price to receive the music. A user who possesses and apparently owns a compact disc containing particular content can be conveniently offered a discount or credit usable towards the purchase of the analogous particular content in a form provided by the electronic content distribution system. Preferably, compact discs are uniquely identified by determining whether their digital fingerprint matches a known reference fingerprint for a compact disc containing the particular content.
