基于小波变换技术的煤矿重要信息的网络安全传输与保存技术

Research on Security Transmission and Preservation of Important Information in Coal Mine on Network Based on Wavelet Transformation

为了在网络上安全传输与保存煤矿重要信息,给出了一种把信息隐藏在风景图像中,从而迷惑攻击者的方法。利用小波变换技术把重要信息隐藏在图像中,不改变图像的视觉效果和质量,然后在网络上传输隐藏了信息的图像,并把图像保存在服务器的数据库中。当我们要使用重要信息时,再从这幅图像中提取出来。仿真实验说明该方法是有效的,能在网络上安全传输保存煤矿的重要信息。本文还发现把信息嵌入到载体图像的小波变换后的中频分量中是最佳方案。

In order to transmit the important information of coal mine safely on the network and save it safely,a method of hiding the information in a landscape image to confuse the attacker is developed in the paper.The important information of coal mine is hidden in a landscape image by using wavelet transformation.The hiding does not change the visual effect and quality of the image.The image is then transmitted over the network and is saved in the server database.When we want to use the important information of the coal mine,the hidden important information of coal mine is then extracted from this image.The simulation experiment proves that the method given in this paper is effective and with the help of method,the important information of coal mine can be safely transmitted on the network and can be safely saved in the server database.It is also found that the best scheme is to embed the information into the medium frequency component of the carrier image decomposed by wavelet transformation.
