The work aims to improve the security of information hiding communication technology and propose a self-destruction type digital watermark hiding communication technology. With this technology, even if someone illegally intercepts information carrier, he cannot get the information content. The image that contained watermark information was segmented into fragments to destroy watermark information inside, so that watermark could not be extracted from a single image fragment. To extract the watermark information is required to synthesize the original watermark image through the image fragment splicing algorithm. Through the experimental simulation analysis, for 8×8 image fragments with pixel size of 32×32, there was no mosaic mismatch of any restored image fragment with watermark image, and the average time of stitching is 1.59 s. Therefore, the algorithm could achieve real-time online mosaic restoration and smooth watermark extraction. The content and existence of information can be hidden successfully from the embedment to the extraction of the watermark through the algorithm. The security of information is higher in the process of the information transmission. Therefore, the information hiding communication technology based on self-destruction type digital watermarking is a technology of high feasibility.
