可见光图像的加密和隐藏信息识别技术

Encryption and hiding information recognition technology of visible light image

为了提高可见光图像的安全性,获得理想的可见光图像加密结果,提出一种新型的可见光图像的加密和隐藏信息识别方法。首先根据原始可见光图像得到辅助密钥与初始密钥,然后采用Logistic和Chebyshev形成的两个混沌序列,并将它们组合在一起得到一个复合混沌序列,最后采用混沌序列对可见光图影像进行加密操作,使密钥隐藏于原始可见光图像中。经过仿真实验对性能分析,可以得到:加密后的可见光图像相邻性相关性很少,很难发现原始可见光图像的信息,具有较高的安全性和保密性。

In order to improve the security of the visible light image and obtain good result of image encryption, a new method of image encryption and hiding information recognition is presented in this paper. Firstly, auxiliary key and initial key are obtained according to original visible image, and then the two chaotic sequences of Logistic and Chebyshev formation are produce and combine together to get a complex chaotic sequence, lastly, chaotic sequence is used to encrypt the visible image, the performance od which is very and the key is hidden in the analysis, we find that the adjacent property of difficult to find the information of the original original image. The simulation experiment is used to get the encrypted image is very small of the proposed meth- image, and has high security and privacy.
