The security analysis of the SARI algorithm
Ping Li · Journal of Shandong University · 2007
The SARI algorithm is the JPEG compression tolerant multimedia content authentication technique,which was proposed by LIN and Chang et al in 2001.Its security depends on the grouping function and the threshold.The cost of eliminating the watermark is small because of its linear function and the single threshold.Theories and experimental results show its weaknesses.Some novel methods are proposed to enhance the system security by using encryption and coding techniques.
