A new audio steganography scheme based on location selection with enhanced security

Abstract

Steganography is the art and science of secret communication. In this paper a new scheme for digital audio steganography is presented where the bits of a secret message are embedded into the coefficients of a cover audio. Each secret bit is embedded into the selected position of a cover coefficient. The position for insertion of a secret bit is selected from the 0th (Least Significant Bit) to 7th LSB based on the upper three MSB (Most Significant Bit). This scheme provides high audio quality, robustness and lossless recovery from the cover Audio.
