Everyday very huge amount of data is distributed over the internet. The distributed data can be easily replicated without error, putting the rights of their owners at risk. Even when encrypted for distribution, data can easily be decrypted and copied. These challenges motivated researchers to carry out intense research in the field of watermarking. In our approach wavelet based video watermarking technique in reversible image is proposed, initially original video frame is undergoing a alternative pixels share further one of the share is transposed and merged with remaining share form reversible image. Next wavelet is forced on the reversible image and marked the secret information in the medium level band of wavelet coefficients. Finally, the inverse wavelet transform is applied and rearranged the shares in the proper structure for yield the watermarked frames. This approach can withstand the quality of the host image after copyright information is marked and robustness.
