Abstract :
Watermarking is a strategy to conceal the picture effectively into any covering object (picture for our situation) so any gatecrasher cant translate it by any methods. Proposed work is another plan of picture watermarking which incorporate pre-handling of cover picture with Discrete Wave Transform (DWT) and Singular Value Decomposition (SVD) Proposed work utilizing an alphanumeric key which at first alters the watermark utilizing basic XOR operation, and at the recipient end this key must be there so collector can extricate the watermark. Proposed work is likewise utilizing torus Automorphism which at first change the watermark into a scramble arrange which cant be acknowledgment as unique watermark. The work is been plan and tried on MATLAB 2013 test system.
