A distinctive data hiding method based on Jigsaw Sudoku is proposed in this paper. Different from other methods, the proposed method is based on Jigsaw Sudoku which is a kind of irregularly shaped Sudoku. Due to the novelty of Jigsaw Sudoku, the proposed method can provide a safer scheme for data hiding than that with pure Sudoku. The proposed method can hide a certain number of 9-ary numbers in a steganographic image which has a corresponding specification. With a 256*256 key matrix stretched from a size 9*9 Jigsaw Sudoku, secret message can be hidden in a vector image byte by byte in the form of pictures. Experimental results show that, the proposed method has a better peaksignal-to-noise-ratio (PSNR) compared with some other data hiding methods.
