Collusion Secure q-ary Fingerprinting for Perceptual Content

摘要: We propose a q-ary fingerprinting system for stored digital objects such as images, videos and audio clips. A fingerprint is sequence. The object divided into blocks each symbol of the embedded one block. Colluders construct pirate by assembling parts from their copies. They can also erase some marks or cut out part resulting in shortened with unreadable marks. give constructions codes that identify colluders once found.
