| Abstract: | To improve the concealment and statistics security, the paper proposed an AMR (Adaptive Multi-Rate) FCB (Fixed CodeBook) Adaptive steganography scheme (AFA), which is based on the search principle of AMR FCB and the correlation of non-zero pulse positions. The key contribution of the scheme is the design of the cost function and the additive distortion function. The optimal probability of pulse and the pulse correlation in the same track were introduced to cost function to improve the statistics security of the proposed algorithm. The hit function b(n) which is used to search for optimal pulse position was added to additive distortion function to improve the concealment of the algorithm. The experiment results show that the proposed scheme has better hearing concealment and security performance to resist the detecting of the existing steganalysis algorithms than the other steganography schemes.
