This paper deals with the achievement of proposed study of steganographic field. The author devised some algorithm to authenticate various images/documents in both spatial and frequency domain using 1-bit-, 2-bit-, and 3-bit-steganography. Major achievements of the proposed study are enhancement of Pick Signal-to-Noise Ratio, Image fidelity and considerable amount of lower MSE, inspite of large volume of data hiding. Most of data hiding technique obtained better/comparable results compare to existing technique. The chronological achievement in terms of PSNR, IF and MSE are shown in this paper.

Keywords: Steganography, MSE, IF, PSNR, Legal document.
