Paper Abstract

A new steganographic method for data hiding in jig swap puzzle images is proposed. First, a color image is taken as input and divided into blocks. Second, each block is rearranged to a new position according to the secret data and a stegokey. The resulting image is a perfect jig swap puzzle. The original image is needed for extracting the secret data. Under the assumption that the receiver and the sender share some common images, the receiver can extract the secret data from the jig swap puzzle image. We also present a scenario for secret data transmission based on an online jig swap puzzle. Experimental results show that the proposed method is undetectable and robust under lossy image compression and format conversion.
