Performance Analysis of LSB Based Watermarking for Optimization of PSNR and MSE

This paper shows the synopsis of digital watermarking, an important solution used for ensuring and assisting data authentication, security of digital media and protection of copyright. The Least Significant Bit (LSB) algorithm is used for Image Watermarking. LSB embeds the image into the original image. In this paper, the original image is compared with the watermarked image using two parameters that areMean Square Error (MSE) & Peak Signal to Noise Ratio (PSNR) . Further the image after watermarking is distorted with the Gaussian noise and then watermark is detected. Its analysis is done using MATLAB.
