基于不可见水印的电子文件传递安全策略探析
|
摘要
不可见水印技术的发展为解决电子文件打印、复印和扫描传递使用中产生的安全风险问题提供了新思路。本文通过对三种代表性的不可见水印技术进行安全性评价,设计出一种面向不可见水印的电子文件传递安全策略,提出利用虚拟打印机实现水印嵌入和利用移动终端实现水印提取的业务流程,论述电子文件传递安全策略的应用场景,并给出了电子文件传递安全策略的系统实现方式与预期效果评价。本文提出的电子文件打印输出后的传递安全策略,可以实现电子文件打印输出后的纸质文件的所有权和使用权的跟踪,能够抵抗恶意的复印和扫描攻击,满足电子文件流转跟踪的安全应用需求。
The development of invisible watermarking technology provides a new idea for solving the security risks caused by the printing,copying and scanning of electronic records.Through analysis of the security of three representative invisible watermarking technologies,we design the transmission security strategy after the printout of electronic records based on invisible watermarking technology.Firstly,we propose typical business processes of the transmission security strategy using virtual printer to realize watermark embedding and using mobile terminal to realize watermark extraction.Secondly we analyze the application scenarios of the transmission security strategy.Finally,the implementation method and the expected effect of transmission security strategy of electronic records are presented.This transmission security strategy can realize the tracking of ownership and use right of paper documents after the electronic records are printed out.The application of this strategy can resist the malicious copy and scan attacks,and meets the security application requirements of electronic records tracking.
