摘要：This paper statistically analyze the effect of each bit position on Stego Image and its contribution towards signal to noise ratio (SNR) and peak signal to noise ratio (PSNR) in Image Stegnography using Discrete Cosine Transform. To statistically analyze SNR and PSNR the information is hidden in each least significant bit position of Discrete Cosine Transform (DCT) coefficients one by one and SNR and PSNR are calculated for each bit position of DCT coefficients. A comparison with the effect of each bit position on Stego Image and its contribution towards signal to noise ratio (SNR) and peak signal to noise ratio (PSNR) of Spatial domain Image Stegnography is also made and presented.
