Abstract :
Achievement of digital rights management standards in digital multimedia distribution applications, while never easy, is further compounded by the persevering investigation of different ways of attacking. In this paper, we analyze a well-known fingerprinting scheme for video distribution. We show the vulnerability of this scheme to specific attacks, namely, the copy attack and the combined collusion with frame-dropping attack. Several experiments were performed to show the effects of theses attacks. Some solutions are suggested in order to prevent these attacks and to enhance the ability of the fingerprinting scheme to reach its most significant aims, namely, the copyright protection and detection of pirates. These solutions are based on valid watermarks incorporating digital signatures, and selective watermarking. Moreover, the application of this revised fingerprinting scheme on a well known multicast protocol yields a significant decrease in the bandwidth and gets around the problem of excessive length of c-secure identity strings.
