水印技术在检验数据安全保护中的应用

在安全生产形势仍然严峻的大背景下,社会对矿山安全日益重视,检测检验机构为矿用产品安全认证提供的检验数据,为矿用产品提供了准入依据。不少企业为了公示其产品合格的依据,将纸质文件以数字图像的方式存储送入互联网,在促进了信息传播的同时,也给非法分子带来了复制、篡改检测数据的机会。文中针对检验报告图像文件的安全保护提出了一种嵌入水印算法。经理论分析和计算机仿真实验,表明该算法计算复杂度高、密钥多、具有高度的顽健性,所隐藏的水印信息具有很好的不可见性,实用性较强。

Watermarking Technology in the Application of Inspection Data Security Protection

In the background of production safety situation is still severe, along with the increasing attention of society to mine safety, detect inspection institutions provide the inspection data for mine product safety certification, provides access basis for mining ＇products. Many products enterprise in order to public the basis of its products, the paper documents to digital image storage into the Internet, which promoted the spread of information at the same time, also brought to the illegal molecular reproduction, tamper detection data, this paper inspection report image files of the security a watermark algorithm is put forward. By theoretical analysis and computer simulation show that the algorithm has high computational complexity and more keys, good robustness, hidden watermark has good invisibility and practice.
