Abstract

Nowadays, it is easy to obtain, manipulate, distribute and store multimedia contents due to evolution of Internet, excellent multimedia tools and low-cost storage devices. Research community and industry has shown extensive interests in developing and implementing possible solutions via digital watermarking. Digital watermarking is distinctive depending on its techniques and applications. In general, digital watermarking is distinguished according to media type (image, audio, video and etc.), visibility (visible and invisible), robustness level (fragile, semi-fragile and robust) and the need for original data (blind, semi-blind and nonblind). The scope of this research is invisible digital image watermarking for gray-scale images using Discrete Wavelet Transform (DWT). The system consists of watermark embedding, attacks and watermark extraction. A new method called subband matching was proposed and implemented. For this method, the I-level DWT coefficients of the watermark image were embedded in 2-level DWT coefficients of the cover image for the same matching subbands. System design consists of introductory details of system input, embedding and extraction processes and system output for the proposed methods. Second section is dedicated to describe evaluations of digital watermarking system.
