Hiding A Message in Mp3 Using LSB With 1,2,3 and 4 Bits

Abstract

Steganography is the art of hiding information in ways that prevent the detection of hidden messages. This paper presentsa new method which randomly selects position in MP3 file to hide a text secret messageby using Least Significant Bit (LSB) technique. The text secret message isused in start and ends locations a unique signature or key.The methodology focuses to embed one bit, two bits, three bitsor four bits from secret message into MP3 file by using LSB techniques. The evaluation and performancemethods are based on robustness (BER and correlation), Imperceptibility (PSNR) and hiding capacity (Ratio between Sizes of text message and MP3 Cover) indicators.The experimental results show the new method is more security. Moreover the contribution of this paper is the provision of a robustness-based classification of LSB steganography models depending on their occurrence in the embedding position.
