The MP3 steganography algorithm based on linbits

This paper presents an improved LSB (Least Significant Bits) steganography algorithm based on linbits by analyzing the structure of MP3 bitstream and the characteristics of the linbits of MP3 encoding. The algorithm is improved by considering the distribution of MP3 frequency coefficient and the selection of block type in MP3 decoding. Experimental results show that the algorithm keeps transparency and has good real-time performance. In addition, it has high steganographic capacity with low complexity and is easy for embedding and extraction.
