Research And Implementation Of Monitoring System Based On Android Phone

With the development and improvement of android system,it has become the mainstream mobile operating system in the market.This article provides technical support for some institutions or individuals,such as monitoring suspects or secret personnel through the study of Android mobile phone information monitoring.It can monitor some special groups to prevent loss or accident.It also can be integrated into the mobile phone system ROM for the monitoring of equipment lost and so on.At the same time,it can provide technical support for malware detection and prevention and has a certain reference value.The main research work of this paper is as follows:1.In this paper,the framework layer of Android system is deeply studied.It mainly analyzes the technology of information acquisition technology,background monitoring principle,data storage technology,multimedia technology,positioning technology,HTTP network connection,SMS sending and receiving technology of Android mobile phone.This article also focuses on the principles of the database system,PHP operating MySQL database,PHP and web interaction,the application of reverse analysis of implant technology.2.It implements a monitoring system for Android phones,which includes listening clients,remote controllers and servers.The monitor client is mainly used to obtain all kinds of information in real time in background of mobile phone and it can send all kinds of information to the server;Remote control side includes two forms,Android sender for the realization of the order of sending,contact inquiries,history saving,and other functions;GSM MODEM remote control instruction transmission system for the end of the page command control;The server is used to receive all kinds of information returned by the storage listening client and to resolve the display information.3.In addition,in order to install the monitor,this article also made some research on Android application implantation,realized the implantation method based on smali language and system ROM implantation.After the test of the system,the listener clients successfully obtained all kinds of information,information upload and receive success,to achieve the default function.The test verifies the feasibility of the monitoring system and has good practical value.
