Paper Title
A Comparative Study of Digital Watermarking Techniques

Abstract
Digital image is one of the most common media used by the Society. Digital watermarking is one of cryptography methods which hide data into digital image so that the data sent cannot be recovered by the unauthorized people. Digital watermarking came as a technique to overcome shortcomings of current copyright laws for digital data. There are so many digital data falsification has occurred. The Primary objective of this paper is to overcome the falsification problem of digital data by applying the watermarking using LSB method (Least Significant Bit), DCT (Discrete Cosine Transform) and DWT (Discrete Wavelet Transform). The experiment demonstrate that on the basis of PSNR (Peak Signal to Noise Ratio) and COC (Coefficient Of Correlation) the DCT achieves better results as compare to other methods. Index Item- Digital watermarking, Least Significant Bit, Discrete Cosine Transform, Discrete Wavelet Transform.
