Implementation Of The Remote Control System Based On Android Platform

With the development of mobile internet technology,smartphone is becoming increasingly common in people's daily life because of its flexibility and portability.The Android platform dominates the smartphone market gradually because of its plenty of advantages,such as open-source,system optimization,rich applications and so on.However,the increasing number of malicious software is threatening the security of Android platform.Especially,remote control Trojans aiming at Android smartphone are causing the worst damage.Malicious users can get the sensitive information,consume phone bill,even forge and deceive others by using Android smartphone Trojans,which damages the interest of phone owner.In order to reduce the damage of Android smartphone Trojans,it is necessary to make a thorough research and analysis on them.And it is an effective method that using remote control system to simulate Android smartphone Trojans.On the basis of researching the existing Android Trojan technology,including implantation technology,hiding technology,background monitoring technology,information interception and back technology,and combining with the remote control technology,this thesis designs and implements a remote control system based on Android platform.The system consists of two parts,which are the control program and the server program.The server program is transplanted to target smartphone through the bundling technology and then runs in silence on background.And the server program will execute control operation according to instructions which are from the control program.And the results will be sent to control program to display.Using this system,we can get basic information,location information,contact information,call logs and SMS of the smartphone.We can also record,take a picture,make calls and send message by using the smartphone.Besides,we can also monitor the call and the SMS constantly online.Thereby,we can control the target smartphone fully.After taking the picture,the system compresses the picture with the image compression algorithm,which improves the network transmission efficiency without image distortion.At last,the correctness and feasibility of the system are verified through the test.Using this system to simulate Android Trojans,we can analyze the operational principle and the process characteristics of Android Trojans,which provides Android smartphone malware detection with corresponding technical support,and which is advantageous for people to enhance the protection awareness.This work has fatal research significance and wider market value.
