Steganalysis of sequential steganography is presented in this paper. Abrupt change in statistics due to sequential embedding is exploited by the proposed technique. Analytical derivations are presented for several cases along with experimental results. Experiments show that the proposed method can be used quite effectively to detect locations and length of messages embedded using spread spectrum steganography.
