Semi-fragile Watermarking Resisting Geometrical Attacks Based on EBCOT
In image watermarking, geometrical attacks can cause the loss of synchronism between the watermarking embedding and the detection, thus lead to the failure of detection.This paper, proposes a method of embedding a perceptually transparent digital signal, named semi-fragile watermarking in the wavelet domain, utilizing the characteristics of EBCOT. So as to detect attacks inflicted on the content and use an algorithm to specify the character of the attack.
