Abstract
Watermarking has been widely famous since past some years. As the threat to protection and copyright is increased, so in order to provide security to the digital documents various methods are used and watermarking is one of them. Through watermarking it is possible to protect the documents and if in any case any changes had done with original data then there comparison with their different bits and that tells us about the document. This paper elaborates about the various effects during changes in the bits of a watermarked image and to calculate the PSNR of the images. Through this paper we try to calculate the best PSNR from the various watermarked images at various bits
