一种基于Android平台的图像加密方案

Image Encryption Scheme for Android Mobile Platform

智能手机等移动终端在现实生活中已经被广泛使用,由其引发的图像安全性问题也越来越突出,保护智能手机等移动平台中的图像信息安全迫在眉睫。传统计算机平台下的图像加密技术已经得到了广泛的研究和应用,但移动平台受限于当前的硬件架构,无法直接继承传统平台的安全性技术。针对智能手机等移动平台中的图像信息安全问题,提出了一种基于Android移动平台的图像加密方案,该方案创新了灰度变换和图像置乱的结合方法。实验研究表明,所提出的方案在图像加密上具有更高的效率,能有效保护移动平台中图像信息的安全性,具有广泛的应用价值。

Mobile platform has been widely used in our real life, such as smart phone, which causes the image security problem is becoming more and more prominent. It is extremely urgent to protect the image information security of smart phone. The image encryption technology by traditional computer platform has been be widely researched and applied, but the mobile platform is limited by the current hardware architecture, so that it can not inherit traditional security technology platform directly. Based on Android mobile platform, an image encryption scheme was put forward in this paper which aims at the image information security problems of smartphones and other mobile platforms. And the scheme is an innovation of the combination between gray level transformation and image method. Experiments show that the proposed scheme has higher efficiency in image encryption, which can effectively protect the security of image infor- mation in the mobile platform, and has extensive application value.
