Optical Medium With Added Descriptor To Reduce Counterfeiting

Abstract: Functionality is described for reducing the unauthorized reproduction of optical media, such as optical discs of various types. The functionality operates by adding a physical descriptor to an optical medium, forming reference descriptor information based on the descriptor, signing the reference descriptor information to produce authenticity information, and adding the authenticity information to the optical medium. At a point of consumption, the functionality operates by reading the authenticity information and reading the descriptor. Based on the information that is read, the functionality performs cryptographic analysis and descriptor-based analysis to validate the optical medium. The functionality includes various provisions to reduce the impact of wear and tear on the above-summarized analysis. The functionality can be applied to stamped or recordable optical media.
