摘要
本文基于原生Android系统,在已有研究Taintdroid项目的基础上对系统进行深度优化,并编写了敏感信息监控软件PrivacyProtect,以此对第三方软件未经"授权"窃取敏感信息的行为进行实时监控。同时,本文在敏感信息外泄拦截的问题中采用"替换"的策略,即使用虚假的信息替换敏感信息,在保护敏感信息的同时保证第三方软件稳定运行。总体上,该系统能有效地实现自主可控。
In this paper, We deeply optimize the Android system on the basis of existing research projects Taintdroid.We write a sensitive information monitoring software PrivacyProtect to monitor the unauthorized sensitive information stealing of third-party software.Meanwhile, this paper adopts the ＂replacement＂ policy in interception sensitive information leakage.That＇s to say, we replace sensitive information with false information, to ensure the stable operation of third-party software while protecting sensitive information.Overall, self-control can be implemented in this system.
