Robust Image Watermarking using Three Domains of SVD
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 11
Abstract
In this paper robust watermarking scheme is proposed using SVD. Initially singular value decomposition is applied to the host image. After SVD, watermark is embedded in three domains i.e., in D, U and V. Watermark is embedded in individual domain as well as combination of domains. Embedding in D domain is implemented by modifying bits. Embedding in U and V domains is implemented by changing coefficient values. Robustness of the proposed algorithm is verified by applying attacks like rotation, rows removal, cropping, salt & pepper noise, speckle noise and gaussian noise. Results indicate the proposed method is able to survive for different attacks.
