RST Invariant Wavelet-Based Image Watermarking Using Template Matching Techniques

Securing any type of multi media data by digital watermarking techniques has gained publicity as a curtail issue for research in the present word. To meet certain market requirements a thorough research work was carried out, the findings of which is presented in this paper. The undertaken procedure has been based on proposing a new image-watermarking algorithm to overcome the RST attacks. The so-called Fourier domain for embedding a template has been employed and the watermark has embedded in Wavelet domain. LPM domain and phase information of the image were used to determine RST attacks. Verifying experiments prove that this algorithm leads to acceptable results with a little computational complexity.
