Self-authentication scheme based on semi-fragile watermarking and perceptual hash function

In this paper, we propose a secure semi-fragile self-authentication watermarking technique based on embedding of perceptual hash derived from discrete wavelet transformation of jpeg2000 encoder. The original image is transformed on wavelet domain using JPEG2000 encoder. Then, we extract LL sub-band coefficients in order to perform perceptual hash. This hash will be embedded back into the same sub-band as a watermark using QIM approach. The experimental results show that the proposed scheme is capable to detect the authenticity of watermarked image while preserving the visual quality.
