An approach of efficient and resistive digital watermarking using SVD

The validation of images taken by digital cameras has become a great concern as the digital photography is gaining rapid popularity. So, due to lack of protection of digital content as they can be easily duplicated and disseminated without the owner´s consent, publishers, artists, and photographers, however, are unwilling to distribute images or other data over the Internet. Therefore, to protect confidential images we propose an efficient digital watermarking technique to deal with this difficult issue. In the proposed technique, the image is first converted into YCbCr from RGB domain then watermark is embedded in Y component of YCbCr using Discrete Wavelet Transform and Singular Value Decomposition (SVD). The results show that our algorithm is resistant toward various attacks.
