An evaluation of MP3 steganography based on modified LSB method

Least significant bit (LSB) is one of the classical methods commonly used for steganography audio. Because of its simplicity, many researchers have interested to develop it. This paper aims to determine the maximum limit of adding bits and its effects on audio quality based on modified LSB method consisting of LSB+1, LSB+2 and LSB+3. Then, this method is evaluated by counting steganography capacity, peak signal to noise ratio (PSNR) and bit error rate (BER) values. Evaluation results show that LSB+3 has the best performance by obtaining the maximum bit of steganography capacity and acceptable of PSNR value.
