Abstract :
A novel steganographic scheme within AAC bitstream is proposed in this paper. Based on the structure of AAC bitstream, the scheme hides secret information using the characteristics of the sign bits of Huffman codeword. The structure of original bitstream and the length of AAC file will not be changed after steganography. Experimental results are given to show that the proposed scheme has high capacity, good imperceptibility, and certain undetectability.
