Strengthen Data Concealing Volume Utilizing LSB Based
Dipak Parikh · 2014
Steganography is a main part of fast developing area of concealing information. Different applications have different requirements of Steganography methods. Most important properties of digital information is that it is easiest to produce and distribute unlimited numbers of its copies. This might undermine the music, Films, Books, and Software Industries. These bring variety of problems concerning protection of intellectual and production rights that badly required solving. Goal of Steganography is to conceal a message in one to one communications. For different image file formats different Steganographic algorithm exists. However in this paper two methods are discussed IMAGE DOMAIN and TRANSFORM DOMAIN. The use of LSB algorithm for image domain reduces the MSE (Mean square error) and improves PSNR (Peak signal to noise ratio) and BER (bit error rate) values, when there is addition of bit substitution. This work is simulated on MATLAB AND RESULTS SHOWS EFFECTS OF VARIOUS MESSAGE BITS FOR CONCEAL BITS. The transform domain conceals secret information in transform space lie in frequency domain.
