Abstract
A system and method for verifying digital recordings that have a plurality of tracks. The invention provides a protection system and method that verifies ownership of a digital recording by requiring the presence of the entire or significant portion of the medium (e.g., CD) as it existed when the digital recording was originally distributed. Verification is accomplished by providing a mechanism that can generate a watermarked digital recording that comprises a plurality of first sections interleaved with a plurality of second sections, wherein the second sections include watermark information relating to data contained in the first sections. A compliant device is also provided that examines the watermarked digital recording and compares the data contained in the first sections with the watermark information to determine if any of the first sections have been removed or modified.
