High Secured Image by LSB Steganography Technique using Matlab

Abstract

Steganography is the one type of powerful technique which is science & art in which we have to write hidden messages, or we hide some important images, audio files, videos in this way that no-one, can find a hidden message which exists in cover images. Steganography is most strong techniques to mask the existence of unseen secret data within a cover object. Actually Stego means "Cover" graphy means "writing" that means It is nothing but we are hiding secret objects in cover image in which medium is different types of images. In practical feasible implementation practical approach would be to make the algorithm as strong as possible. In steganographed images are the most powerful objects that means cover objects, and therefore importance of image steganographed which can Embedding secret information inside images requires systematic computations, and therefore, at the time of designing steganography in hardware which getting high speeds in steganography. Various metrics were used to judge imperceptibility of steganography. The metrics in Matlab indicates how similar or dissimilar the stego-image compares with Cover. This paper intended to demonstrate LSB steganography, a commanding method for data and image security, its implementation on FPGA and calculate its parameters like SNR, BER for its to analyze its hiding capacity, And also Comparing these parameters of FPGA implementation with that of MATLAB implementation. In this thesis we will demonstrate LSB steganography, which is a powerful method for data and image security.
