LSB based audio steganography preserving minimum sample SNR

Steganography is the art of hiding a secret data in another data. Audio steganography is a technique for hiding information in an audio signal. One of its methods is least significant bit (LSB) coding. The proposed system is embedding bits in LSBs while keeping the minimum signal to noise ratio (SNR) for each sample as required. This method gives a maximum number of embedding bits as possible, and increase the security by keeping secret the minimum required sample SNR. Also the length of the required audio carrier to embed the message changes according to the minimum required sample SNR.
