Research And Implementation Of Privacy Information Protection System Based On Android Platform Mobile Terminal

In recent years, smart mobile terminals and tablet PCs for the mainstream smart mobile devices has become the main terminal of the Internet age, which occupies a dominant market position. However, a large number of security risks seriously affect the Android system security and user privacy, malicious applications is an important security risks Android intelligent system. Android intelligent mobile phone security threats around the world and privacy protection, how to further improve the information data of Android operating system on the degree of safety will be the key research contents research institutions. Android mobile terminal platform for privacy protection is facing the following problems: the analysis of the software database in automatic detection of malware; information protection equipment operation occupies more resources, the overall operating rate of equipment slow drag.In this paper, we mainly study the privacy protection security of Android operating system, and put forward the research and implementation of mobile terminal privacy information protection system based on Android platform:a) Research and analysis of the mobile terminal privacy protection and information protection theory and technology, analysis Android intelligent system architecture, intelligent mobile terminal based platform requirements; investigation of the Android security mechanism research determined intelligent terminal of the system partition, safe mode, file system permissions, the process of the sandbox, authorization mechanism and application signatures, summarize and analyze the authority mechanism of the Android security mechanism, data storage, broadcast mechanism, malicious intent jump and decompiling security threats, identified Android file encryption security threats to the system and the foundation.b) Design of multi tier synergetic Android privacy information protection system, from the multi tier architecture of Android system of construct the APK security marked module, user switching module, dual user privacy mode in control module and information privacy control module are combined to construct process architecture and implementation of the APK security label and audit, automated user switching program and the audit process and privacy information labeling and inter component communication review process.c) The implementation of safety signs and access co ntrol security system based on, system based on A ndroid 4.1, respectively, to build the APK safety labeling module, user switching module, privacy control module and information privacy control module of the system platform, in the Android emulator system deployment, to design the system running efficiency and effectiveness are tested.The results showed that in this paper, the design of the Android platform based on mobile terminal information privacy protection system, prevent cell phone use user information data suffer from leakage and achieve Android smart APK installer package access control and user privacy protection.
