A Secure Quantization-Based Watermarking Scheme Using An Improved Statistical Model in the Wavelet Domain
In this paper, we have proposed a secure semi-fragile watermarking technique for content authentication of digital images. A binary image is encrypted in an efficient way and then embedded as the watermark for tamper detection. The watermark is embedded by applying a quantization index modulation process on Euclidean norm of singular values of blocks in the wavelet domain. To avoid visual degradation of watermarked image, we have enhanced a model to take into consideration blocks statistics of the host image. Experimental results are presented for well known images to demonstrate effectiveness of our method.
