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

摘要

Steganography is the art of hiding information in ways that prevent the detection of hidden messages. Thispaper presentsa new method which randomly selects position in MP3 file to hide a text secret messagebyusing Least Significant Bit (LSB) technique. The text secret message isused in start and ends locations aunique signature or key.The methodology focuses to embed one bit, two bits, three bitsor four bits fromsecret message into MP3 file by using LSB techniques. The evaluation and performancemethods are basedon robustness (BER and correlation), Imperceptibility (PSNR) and hiding capacity (Ratio between Sizes oftext 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 LSBsteganography models depending on their occurrence in the embedding position.
