with the widespread distribution of digital information over internet, the protection of intellectual property rights has become increasingly important. Digital Image Watermarking is one such technology that has been developed to protect digital images from illegal manipulations. This paper deals with watermarking technique based on Integer Wavelet Transform (IWT) and Singular Value Decomposition (SVD). In this proposed work, the cover image is decomposed at second level into four sub-bands bands (LL, LH, HL and HH) using IWT and thereafter SVD is applied to LL sub band. The singular values of cover image are embedded with singular values of watermark by making use of scaling factor. Performance of proposed work under with and without attacks has been analyzed. Experimental results demonstrated that IWT-SVD based watermarking technique is imperceptible and robust against most of the applied attacks such as; noise addition, resizing and filtering.
