本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力。(In this paper, two-dimensional chaotic map based on digital image watermarking algorithm, Chaos with random noise and the likelihood of extreme sensitivity to initial conditions and so on. Two-dimensional chaotic map will be scrambling after the digital watermark embedded image signal of the low-frequency coefficients in wavelet domain, the realization of a digital watermark hidden, security and stability the use of two-dimensional chaotic map on Arnold transform scrambling watermark signal, not only enhances the confidentiality of the watermark signal at the same time improve the visual image shear resistance attacks.)

说明： 文档一体化系统是从档案管理的实际情况出发而研发的，总体上力求简明、实用和功能完备；操作风格上，尽可能地向大家所熟悉的微软产品靠近。它具有文档一体化功能，乡镇、机关档案室可以从收发文登记开始管理，以归档类目为桥梁，通过归档操作，最终完成归档工作。此系统启运方便快捷。(Document integration system is developed from the actual situation of archives management, and strives to be concise, practical and functional in general. In terms of operation style, it is as close as possible to Microsoft products that you are familiar with. It has the function of document integration. Township and government archives office can start management from the registration of receiving and receiving documents, take the archiving category as a bridge, and finally complete the archiving work through the archiving operation. This system is easy to operate.)
