摘要：This work contributes to the multimedia security fields by given that more protectedsteganography technique which ensures message confidentiality and integrity. An AdvancedLeast Significant Bit (ALSB) technique is presented in order to meet audio steganographyrequirements, which are imperceptibility, capacity, and robustness. An extensive evaluationstudy was conducted measuring the performance of proposed NLSB algorithm. A set of factorswere measured and used during evaluation, this includes; Peak Signal to Noise Ratio (PSNR)and Bit Error Rate. MP3 Audio files from five different audio generators were used duringevaluation. Results indicated that ALSB outperforms standard Least Significant Bit (SLSB)technique. Moreover, ALSB can be embedding an utmost of 750 kb into MP3 file size less than 2MB with 30db average achieving enhanced capacity capability.
