Image watermarking resistant to geometric attacks based on SIFT feature
Wei Na, Kazuhiko Yamaguchi (UEC) EMM2011-71
Abstract (in Japanese) (See Japanese page) 
(in English) In image watermarking issue,geometric attacks are known as important and difficult problem to resist,which can desynchronize the location of the watermark and hence causes incorrect watermark detection.In this paper, we propose a new content based image watermarking based on SIFT(Scale Invariant Feature Transform) detector.The proposed scheme has strong tolerance toward geometric attacks.The embedding of the scheme is as follows.Firstly, we choose the feature points which are stable for embed watermark from the original host image by using SIFT detector,and decide the circular regions for the points.Secondly the watermark is embedded into DCT(Discrete Cosine Transform)regions within the circle using the QIM(Quantization Index Modulation)method.Experimental results show that the proposed image watermarking is not only invisible and robust against geometric attacks, but also can embed more watermark information than the previously known method.
