Adaptive SVD-Based Digital Image Watermarking,ations have also raised concern about copyright issues and unauthorized modification and distribution of digital data. Digital watermarking techniques which are proposed to solve these problems hide some information in digital media and extract it whenever needed to indicate the data owner. In this

Robust Audio Watermarking Based on Log-Polar Frequency Index,verage Fourier magnitude over the log-polar frequency index(.), which can resist these attacks. Theoretical analysis and extensive experiments demonstrate that . is an appropriate embedding region for robust audio watermarking. This is the first work on applying log-polar mapping to audio watermark.

Blind Detection of Digital Forgery Image Based on the Local Entropy of the Gradient,ficial feather operation, which is necessary to create a smooth transition between a forged image region and its surroundings. The local entropy of the gradient is used to determine the forged region, and the credibility is computed to show the reality level of the image. Results of experiments on s
