数据信息安全的移动信息化平台优化研究

Data information security of mobile information platform optimization

当前高校及移动信息化平台发展的关键问题依然是信息泄露、信息安全存储的问题,文中针对平台应用的小波信息安全的问题进行了改进。首先对小波分解频带和隐藏位置的确定进行了优化,通过改进算法的抗攻击性测试得出,算法系统对于滤波及噪声等常见攻击具有一定的抵抗力。进一步提出了一种基于小波变换域的信息隐藏算法,实验结果表明算法得到的嵌入图像的不可见性及安全隐蔽性相对比较好。这一研究,对外高校移动信息安全问题的改进具有一定的实际意义。

The current informatization and mobile platform development is still the key problem of information disclosure, information security storage, in accordance with the wavelet of platform information security problem is improved. Frequency band of wavelet decomposition and optimized for hidden position,for improving the algorithm＇s resistance to aggressive tests,system for filtering algorithm and the common attacks such as noise resistance. Further it presents an information hiding algorithm based on wavelet transform domain,the experimental results show that the algorithm the embedded image invisibility and security in the form of concealment is relatively good. The study on foreign university mobile information security improvement has a certain practical significance.
