摘要
Android系统是最热门的移动智能终端之一,保护Android用户的隐私特别是图片信息非常重要。目前常见的Android加密工具通常采用手动选取图片的方式对图片进行加密保护,这种手动加密方式在加密实时性与用户体验上存在不足。针对这种情况设计实现了一种透明图片加密系统。该透明图片加密系统通过对Android拍照动作进行监听,能够自动拦截并获取系统最新的拍照图片,并利用128位AES加密算法实现图片快速加密保存。实验结果表明,该系统可以实现图片的自动加密,且在图片加解密过程中,系统透明进行,用户不需要额外操作,降低了系统的使用难度。
Android operation system is one of the most popular mobile intelligent terminals. For Android users,the protection of personal privacy is of great importance. At present,the common Android encryption tool usually uses the method of manually selecting the picture to encrypt the picture. This manual encryption method is deficient in the realtime encryption and user experience. In this case, a transparent picture encryption system was designed and implemented. This system could intercept and catch the newest picture automatically by monitoring the photograph action,and then took advantage of AES-128 encryption algorithm to encrypt picture quickly. Experimental results showed that this scheme could encrypt picture automatically,meanwhile,the process of encryption and decryption were transparent for users which could reduce the difficulty of use without additional operations.
