摘要：Digital Watermarking is a process of embedding unnoticeable signal in an image in the form of text and image in such a way that intruder is no able to trace the signal to enhance Copyright Protection. This Paper presents an efficient Watermarking Technique for Digital Media Content Protection and Copyright Protection. Watermarking is a technique to embed hidden and unnoticeable signal into digital media in such a way that if an intruder wants to copy it, he can be caught on the basis of Copyright protection and Ownership Identification. There are many Techniques that are available to watermark the data, proposal we are discussing DWT Technique which is most robust to attacks rather than LSB for the protection of Digital Images. We are going to find the Quality loss after the addition of watermark after applying various attacks on Watermarked Image, the more the quality loss will be there lesser will be the efficiency of Watermarking. There will be many factors that can effect the quality of the Images after the addition of Watermarking that are discussed in Later Section. The Creating on GUI and Implementation of our purposed Algorithm is realized using MATLAB.
