| Talk Title: | Digital Fingerprinting in Digital Cinema Systems |
| Slides: | 4-5.ppt |
| Abstract: | Digital fingerprinting is a forensic technique to assert authorized ownership and counter piracy of multimedia content. To combat illegal redistributions and digital theft, a distributor uniquely marks every copy by embedding traceability (TA) codes with collusion-secure and frameproof properties, making the deterrence and persecution of a coalition of dishonest users possible. With the advent of digital cinema systems in recent years, TA codes may very well offer the best security and protection measures for new digital releases against movie piracy. It is thus the purpose of this research to investigate TA codes, analyze their applicability in digital movies, and implement an embedding scheme in a digital cinema context. Practical issues to be addressed include robustness and security of embedded TA codes under data compression and format conversion. Overall performances and further applications of the embedding scheme will also be discussed. |
