随着网络舆情对国家政治秩序和社会发展稳定的影响与日俱增，非法传播、提取，恶意篡改和伪造网络图像舆情信息成为舆情信息传播环节的最大安全隐患之一。基于数字指纹技术在国内外的应用实践，将混沌序列加密算法嵌入水印形成数字指纹，从而设计一种新的基于传输系统的图像舆情信息安全体系。经实证研究，该体系能有效防止图像信息的非法传播，避免其被恶意篡改和伪造，并能甄别其真伪，从而增强网络图像舆情信息传播的安全性、合法性。

With the increasing influence of the network public opinion on the national political order and social development stability, in-formation securities is challenged by the illegal spread, extraction, malicious tampering and forgery of public opinion information on net-work image information of public opinion. Based on the practice of digital fingerprint technology at home and abroad, this paper applied the chaotic sequence encryption algorithm to watermark, which turned to digital fingerprints to form a new image transmission system for image information security of public opinion system. Empirical research shows that this technology can not only effectively prevent the ille-gal spread of administrative information and avoid malicious tampering and forgery, but also can distinguish between truth and false so as to make the image information transmission legitimate and secure, which has important theoretical and practical significance in the trans-mission process of network image information of public opinion in China.
