摘　　要：Android系统是最热门的移动智能终端之一,保护Android用户的隐私非常重要。该终端加解密隐私保护系统,利用hook技术来捕捉并劫持用户进程对文件的读写操作,通过添加具有加解密功能的函数模块,替换用户动态链接库中原有的读写函数,从而达到加解密的目的。系统的核心加解密模块采用具有易于实现且运行速度快的RC4算法,保证了运行效率。另外,在加解密过程中,用户不需要额外操作,降低了系统的使用难度。Android is one of the most popular mobile intelligent terminal operating system, and it is very important to protect the privacy of Android users. The terminal encryption and decryption of the privacy protection system uses hook technology to capture and hijack the read-write operations of the user process to the documents. By adding a function with encryption and decryption function module, it replaces the original read-write function in user, s dynamic link library to achieve the purpose of encryption and decryption. The core encryption and decryption module of the system adopts the RC4 algorithm which is easy to implement and run fast, and ensures the running efficiency. Also in the encryption and decryption process, the user does not require additional operations, reducing the difficulty of using the system.
