摘要:	A method for creation of a new-style mosaic image, called tile-overlapping mosaic image, for the purpose of information hiding is proposed. Each tileoverlapping mosaic image is created by varying the overlapping degrees of the adjacent rectangular constructing units - tile images. A secret binary data stream is embedded into a cover tile-overlapping mosaic image by utilizing the overlapping degrees of adjacent tile images. And data recovery is accomplished by detecting the overlapping degree of every pair of adjacent tile images in the resulting stego-image. Experimental results show the feasibility of the proposed method.
