- W2387878704 abstract "An affine transform invariant blind watermarking technique is proposed based on secret sharing and high order spectra in this paper.Watermark is divided into n shadows to enhance security,according to secret sharing scheme,only t or more than t shadows can reconstruct the secret watermark.The watermark is embedded in the rotation,scaling,and translation invariant vector of bispectrum.Bispectrum detection is utilized to detect whether the test image contains the watermark or not.Even with small signal noise ratio,the detector can get a high detection probability.The independent component analysis is adopted,and thus the shadow could be detected as well as extracted.Before watermark reconstruction,one way hash function is employed to withstand cheating attacks.The experimental results show that the proposed algorithm is robust against a variety of attacks by watermark test software-Stirmark." @default.
