Abstract

Statistical undetectability is a common problem in current MP3 steganography. In this paper, a novel adaptive scheme of MP3 steganography is proposed for obtaining higher secure payload under the framework of distortion minimization. To avoid disabling MP3 encoder in the embedding process, a mapping construction algorithm using Huffman codes of equal length is realized to hold the length of stego codestream. Furthermore, a content-aware distortion function is designed to achieve optimal masking effect via the psychoacoustic model (PAM). Experimental results show that our method achieves better performance
than others in terms of security and secure payload, the detection accuracy of the proposed method is lower than 55% under 128kbps when the relative payload is equal to 0.25.
