A Robust Watermarking Scheme Using DWT and SVDAuthor : B. Gopi and T. Sudha
Volume 8 No.3 Special Issue:June 2019 pp 85-89
Singular value decomposition is in use quite recently in many applications. The SVD is being used for many applications along with other techniques. In this paper a robust watermarking scheme was proposed by using SVD along with wavelet transform. In addition to normal hiding scheme a random signature was used to improve its robustness against spurious intruders. The unitary matrices are used to generate a signature which is going to be embedded into the fourth level decomposition of cover image. After extracting the watermark at the other end, it will be checked with the signature embedded. If these signatures are matched the unitary matrices will be used to extract watermark from watermarked image. Different attacks are considered and the simulation results have shown that the extraction of watermark after attacks have shown minor effect only.
