Robust Lossless Image Watermarking in Integer Wavelet Domain Using SVD
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The aim of digital watermarking is to hide some secret information or logo into the multimedia content for protecting the content from unauthorized access or illegal use .A robust and secure technique is required to protect multimedia data as it can be easily produced as illegal copies. Digital watermarking is used for Intellectual Property Rights protection and authentication. In this paper, a watermarking scheme based on Integer wavelet transform (IWT) and singular value decomposition (SVD) is implemented. The watermark image is embedded on the elements of singular values of the low-low (LL) Sub band of original image. The watermark image is extracted which is highly correlated with the original watermark image. The proposed algorithm is robust and authenticated under different attacks.
