A Huffman Coding Section-based Steganography for AAC Audio

Jie Zhu, Rang-Ding Wang, Juan Li and Di-Qun Yan

Steganography techniques can be used to embed secret information into audio signals. A Huffman coding section-based steganographic scheme for MPEG-2/4 Advanced Audio Coding (AAC) audio is proposed in this study. Based on the characteristics of Huffman coding section, the scheme hides secret information by modifying the sections of Huffman coding without affecting its normal process of encoding. Experimental results are given to show that the proposed scheme not only has a larger capacity, 15 bits per frame averagely but also does not change the statistical properties of the audio carrier which means having certain undetectability. In addition, the scheme does not affect the quality of audio carrier, having good imperceptibility.
