We have implemented the watermarking technique for the copyright protection based on 3- level discrete wavelet transform (DWT). In this technique a multi-bit watermark is embedded into the low frequency sub-band of a cover image by using alpha blending technique. Digital Watermarking is a kind of process of embedding unnoticeable signal in an image in the form of text or image in such a way that intruder is not 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. This paper embraces invisible Image Watermarking that uses Discrete Wavelet Transformation (DWT) for embedding the secret message or logo into the target image, the work has been performed using MATLAB.
