Matrix-based robust joint fingerprinting and decryption method for multicast distribution of multimedia

A VQ-Based Joint Fingerprinting and Decryption Scheme for Secure and Efficient Image Distribution

“…The flexibility of maximum capacity of fingerprint [15] Yes Higher Yes [16] No Higher Yes [17] No Higher Yes [18] Yes Higher No Our scheme Yes lower Yes where and denote the embedding rate and the modified blocks, respectively. (n+1)/2 n denotes the maximum embedding rate.…”

“…Comparisons with Related Mechanisms. The functionalities of the proposed method are further discussed and compared with mechanisms [15][16][17][18]. Table 2 illustrates the comparisons of our method and related mechanisms.…”

“…Although the improved functionality of [18] achieves a blind fingerprint extraction, the computation and communication overheads are still higher, and the total amount of embedded fingerprint is still constant and inflexible due to the fact that the total amount of the fingerprint can only be equal to the block size of the specified VQ image. The performances of [15][16][17] are less satisfactory in terms of transmission cost. In addition, schemes [16,17] cannot achieve a blind fingerprint extraction.…”

“…The other was to utilize the dynamic-tree and session key into the substitution process. Recently, a larger number of JFD schemes on the basis of Lin et al method have been proposed [15][16][17][18]; in these schemes, the security of JFD methods was further enhanced and applied into different types of practical scenarios. Unfortunately, there still exist some problems to be solved for the original scheme [14].…”

Parallel Joint Fingerprinting and Encryption for Social Multimedia Sharing Based on Game of Life

“…In [15], the authors proposed a new genetic fingerprinting scheme for multicast video protection. Joint fingerprinting and decryption (JFD) schemes are proposed for multimedia security [16][17][18].…”
