Abstract: This work develops an anti-forensic steganography system using the proposed multi-bit MERs with flexible bit location embedding method (multi-bit MER_FBL embedding method) to overcome the problem of forensics and to achieve high performance including both large embedding capacity and high image quality. The proposed multi-bit MER_FBL embedding method hides multi-bit (k-bit, k ≥ 1) logo/secret data into any adjoining (starting with the ith location) k-bit b_ib_i−1…b_i−k+ of cover data only introduces MEE in the range of 0 to ±(2^k - 1)2^i−k; moreover, its flexible bit location enhances the embedded security as security increases as the embedding location closing to the MSBs of cover data. We thus develop a thresholding mechanic to evaluate the anti-forensics degree of the proposed method. Finally, antiforensics of the proposed steganography systems are demonstrated using the visual attack and the statistical attack of Chi-square analysis.
