| Abstract(in English) | In the previous papers, the authors proposed a data embedding method based on the phase modulation of sampling lattice. In this method, the image data are re-sampled using the two-dimensional sampling lattice whose phase was modulated according to information to be embedded. In this paper, the simplest collusion attack based on the use of the arithmetic mean of pixel value is examined. The results show that the proposed method can disclose the plural collusion users. |
