ABSTRACT:
A system and method for verifying digital recordings that have a plurality of tracks. The system includes an encoder that: divides the digital recording into a plurality of sections and associates a random number with each section; calculates an identifier as a function of the associated random numbers; and watermarks sections within a block of sections with the associated random number and a portion of the identifier. A verification system is provided that extracts the random numbers and identifier portions; calculates a first identifier as a function of the extracted random numbers; calculates a second identifier based on the identifier portions; and compares the first identifier and the second identifier.
