Abstract(in English)	We have recently studied digital watermarking techniques based on modifying the spectral coefficient of an image, and have presented a model of the watermark embedding and extracting processes and a model of watermark distortion caused by image processing and attack of a watermarked image. In this paper, based on these models, we formulate the watermark detection problem as a kind of blind deconvolution problem. Then, we discuss a solution to this problem using Bayesian estimation.
