Prevention of Geometric Attacks Using Image Watermarking Technique
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 1
Abstract
In this paper, a robust image watermarking algorithm which was based on singular value decomposition (SVD) and discrete wavelet transform (DWT) was proposed and simulated for protecting real property rights. To obtain this we divide the host image into four non- overlapping sub bands called sub images and then watermark is embedded in that sub images. Its embedding algorithm hide a watermark in sub-band blocks in the low–low (LL), low-high(LH), high-low(HL) and high-high (HH) sub-bands of a target non-overlapping block of the host image by modifying singular values (SVs) on SVD version of these blocks. The watermark extraction algorithm was designed to estimate the original coefficients. Then we will verify for various geometric and Gaussian attacks such as translation, scaling, reflection, noise, mean, median etc., and finally we will extract the attacked image and water marked image separately and will check for its robustness. Experimental results showed that the proposed scheme made significant improvements in terms of both transparency and robustness and was superior to the existing methods which were considered in this paper.
