Optical Wireless Transmission under Static Image Information Hiding Method Exhibits the Simulation

为了更好的保障光无线通信环境下图像信息传输的安全性与质量性,需要进行光无线传输下静态展品图像信息隐藏。但是采用当前方法进行图像信息隐藏时,无法保障图像的隐藏质量,存在图像信息隐藏误差大的问题。为此,提出一种基于LSB的光无线传输下静态展品图像信息隐藏方法。该方法先融合于同态公钥加密方法在隐藏前依据密钥选择图像需要隐藏的信息像素,采用差分扩展方法将像素的各比特数据嵌入到其它像素中,在此基础上组建图像的伪像素,在隐藏后替换需要隐藏的信息像素,采用Logstic方程设计出图像置乱的混沌序列发生器,生成随机混沌序列,依据其结果完成光无线传输下静态展品图像信息隐藏。仿真证明,所提方法图像信息隐藏质量高,为保障光无线通信环境下图像信息传输质量提供可行的依据。

In this paper, we propose a method for information hiding of image of static exhibit under wireless transmission of light. Firstly,integrated with the method of homomorphism public key encryption, the information pixel to be hidden was selected according to secret key before hiding, and difference extension method was used to embed each bit data of pixel into other pixel. Then, on that basis, pseudo - pixel of image was built and information pixel to be hidden was replaced after hiding. Moreover, using Logistic equation, a chaos sequence generator of image scrambling was designed, and random chaos sequence was generated. Finally, according to the results, the information hiding of image was completed. Following conclusions can be drawn from simulation that the method has high quality of information hiding of image and can provide feasible gist for ensuring quality of information transmission of image under wireless communication of light.
