Research And Implementation Of Detection Of Malware On Android Platform

With the comprehensive development of science and technology, Androidoperational system for smart phones gradually becomes an important part of people’slives. Android smart phone for voice calls, send and receive e-mail, to deal with allkinds of information, People enjoy the convenience brought by Android smart phone,but meanwhile the user’s privacy is also facing a huge threat. Android smart phonesystem has become largest smart phone platform for malware’s attacking, and the stealof personal privacy has also become a major attack method. Therefore, it’s become ahotspot of research and discussion that how to protect user privacy information securityin the Android mobile phone platform.Based on the Android original security mechanism，this paper tries to design andimplement a new dual-user privacy information protection system model. The mainbody of this article includes the following two aspects:Firstly, the thesis introduces the design of information protection of personalprivacy on the Android platform. The thesis introduces the Android system framework,application components, a detailed analysis of the security mechanisms risks thatAndroid system is facing and privacy information protection in the current mechanism.Finally, in order to solve this privacy security issues, the thesis designs a dual-user modeabout privacy information protection system. The model design includes four modules:user audit module with two-user switch; the APK safety labeling module’s privacypermissions for installation package safety audit; Access to privacy information controlmodule’s achievement about privacy permissions itemized refinement and dynamicmodification; Privacy information control module by staining of privacy informationmark against the information disclosure between applications. Through four modules,the design achieves multiple protective effect of private information by completing theaudit of the APK install package sources, fine-grained permissions dynamic control,privacy and data access control and other protective means to.Secondly, the achievement and test privacy protection system model part. As forthe privacy information protection system model, the thesis analyzes the technical details of each module to achieve the information privacy protection system. Last withthe tested，the thesis distinguishes the privacy rights of installation package comingfrom different sources in different initial user mode, the privacy access to information inthe same application under different user mode, the same application in a differentprivacy permissions. Also the thesis analyzes the validity of the prohibition about theaccess to privacy information protection including data and communication, and theefficiency of the overall system.
