Fast Fourier Transform based Hybrid Image Watermarking using Arnold Scrambling
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 2
Abstract
Aiming at the problem of poor robustness of existing digital watermarking algorithms to signal processing and geometric attacks, this paper provides modification in SVD, which is neglected by many researchers. This research work proposes a new integrated watermarking technique which will integrate DCT, DWT, FFT and modified SVD. The SVD will be modified by Arnold transform. Proposed algorithm will combine the advantages of the well-known watermarking techniques FFT, DCT, DWT and modified SVD. DCT will be applied to the input cover image. Then FFT will come in action, and followed by DWT to form sub-bands. To accomplish inaudibility HH wave band will be selected for additional wave level decomposition. Modified-SVD will be then applied to HH and values will be adapted with the values of the image going to be watermarked. Thus the proposed technique has better results because the insertion is more secure as followed by several well-known techniques. Thus the results are more efficient even in case of some well-known techniques.
