The Effect of Data Hiding at Various Bit Positions on Audio Stegnography in DCT Domain

In this paper the authors presents the statistical analysis of various quality measuring parameters of audio stenography, e.g. Signal to Noise Ratio (SNR), Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE), for different bit position substitution in an audio cover file in Discrete Cosine Transform (DCT) domain. Interestingly the resulted Mean Square Error (MSE), Signal to Noise Ratio (SNR) and Peak Signal to Noise Ratio (PSNR) for each bit position shows very insignificant variations in the values of the quality measuring.
