| 目的 为了提高信息隐藏通信技术的安全性，提出一种自毁式数字水印隐藏通信技术，即使非法者截获信息的载体也无法获得信息内容。方法 将生成的含水印信息的图像分切成图像碎片以此破坏内嵌的水印信息，使水印信息无法从单个的图像碎片中提取，必须经过图像碎片拼接算法合成原始含水印图像后才能提取水印信息。结果 通过实验仿真分析，对于大小为32×32像素的8×8个图像碎片，复原的含水印图像无任何图像碎片拼接错位，拼接平均耗时为1.59 s，因此能实现实时在线拼接复原并顺利提取出水印信息。结论 从信息的嵌入到最后信息的提取都能顺利地隐藏信息的内容和信息的存在，信息传递过程中信息的安全性能好，因此，自毁式数字水印信息隐藏通信技术是一种可行性极高的信息隐藏通信技术。 |
| 英文摘要: |
| 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. |
