The wavelet coefficients in 2-D discrete wavelet transform (DWT) subspaces have a peaky, heavy-tailed marginal distribution that can be well described by a Gaussian mixture statistical model. In this paper, a multiscale implementation of fragile watermarks based on the Gaussian mixture model is presented. The presented new method can embed a message bit stream, such as personal signatures or copyright logos, into a host image. With the embedded message bits spreading over the whole image area,doi:10.1109/icassp.2004.1326569 dblp:conf/icassp/YuanZ04 fatcat:dinqomb7c5drhfdfv3frtemfma
