Abstract

This chapter discusses on forensic tracking through digital watermarking for secure multimedia distribution. The existing watermarking schemes are elaborated and their assumptions as well as limitations for tracking are discussed. Especially, an Independent Component Analysis (ICA) based watermarking scheme is presented, which overcomes the problems of the existing watermarking schemes. Multiple watermarking techniques are used where one watermark is used for ownership verification and the other one is used to identify the legal user of the distributed content. In the absence of a priori information, i.e. the original data, original watermark, embedding locations as well as the strength, our ICA technique provides efficient watermark extraction scheme with the help of side information. The robustness against common signal processing attacks is presented. Lastly, the challenges in the forensic tracking through digital watermarking techniques are discussed.
