The Research On The Technology Of Listen And Anti-listen In Android System

At present, there are too many applications which are based on smart phoneto choose by the users of smart phone. The diversification and complex ofmobile service allow the issue of information security of the smart phonebecome more and more important and more complex. The research on thetechnology of listen and anti-listen in Android system is very important andvaluable to protect users’ information on the smart phone to steal by malware.Published by Google, the Android mobile system is the first open mobilephone platform of the world. It is completely designed for mobile devices. TheAndroid is composed by a series of application software, operating systems,middleware and user interface. As the current mainstream mobile platform, theAndroid has a large user group. In this paper, we combined the technology ofAndroid application development and security of user’s message. We study theways which are used to listen user’s message by the malware and how toprevent the listening.Firstly, there is a brief introduction about the Android platform. It includes theanalysis about the characteristics of Android system architecture and makesthe roles of each layer in Android system clear. What is more, we explain thesecurity mechanisms in Android system and the principles of security design indetail.Secondly, we focus on the handling mechanism about the SMS in Androidsystem. And we understand the entire system process of receiving and sendingSMS. Moreover, we analyzed and designed the modules of the listen andant-listen system in Android.Thirdly, we elaborated how to build the Android development environmentand the way to implement. According to the actual conditions, we tested themain module of the system.Finally, there is a summary about what we have done and a plan that we willcomplete in the future.
