The Design And Implementation Of The Remote Monitor System For Android Platform

With the high-speed development of mobile Internet, people are becoming more and more dependent on the use of mobile intelligent terminal, especially the smart phones. However, more convenient intelligent terminal often save the user’s privacy information because of the needs of the users, such as phone contacts, messages, photos and so on, even including the current user’s geographic location. It is obvious that the information preservation sometimes provides the convenience for people’s daily life, and sometimes will also be a potential safety hazard. The users of mobile intelligent terminal will not really want the personal privacy information to leak out.Therefore, in view of the mobile terminal, users’ privacy information security protection research is imminent, especially in view of the Android operating system, the study of the Android mobile terminal is imperative. Because of the characteristics of open source, Android is much loved by mass production manufacturers, in the operating system market share of the mobile terminal is also rising, and there is a trend towards multi-platform development. Yet there is no information on an appropriate object of user privacy protection methods based on the Android platform, therefore decided to design a attack scenario environment which without the user’s consent to obtain information, theft the information in order to establish a prototype system to lay the foundation for further study of security methods.The Android platform remote monitoring system adopts the design of the end-to-end development for mobile terminal information acquisition subsystem and monitoring terminal information check subsystem. On the mobile terminal subsystem mainly design the testing, information acquisition and video acquisition for three big functions. The main function is non-inductive monitoring without the user’s awareness to open camera, and use H.264to code the video shooting in real time, then through the RTP protocol and the SDP file stored on the server to stream the media communication.Mobile terminal not only achieve the function of non-inductive video monitoring, and realized the function of uploading users’ privacy information in the background, basic information such as phone information, contacts, SMS, call records, the geographical position, the photographs and users’ other privacy sensitive information.In the view of server, select Tomcat as a Web server, using Mysql as database to store the upload information, and due to the users’ privacy information of mobile terminal which is uploaded contains files such as photographs and the SDP file, so be classified to upload information processing. Text information, such as contacts, messages directly deposited in the database; File information requires the server to receive, and stored in large capacity disk, then keep the file path information stored in the database.Monitor terminal information check subsystem is built into the B/S architecture, realized to check the basic information, check the contact information, check the phone records, check the short messages, check video monitoring, check the view of multimedia information and check the dynamic information as seven major functions. General information display mainly through the server to query the database data, video monitoring requires using VLC player to decode the SDP file on the server to receives the video images from mobile terminal.In summary, this paper designed the remote monitoring system based on the Android platform includes mobile terminal information acquisition subsystem and monitoring terminal information check subsystem. Finally completed the function of the video monitoring and upload information in the background. So set up a prototype system aimed at stealing the users’ privacy information, laid the foundation for the next step to research the protection method of privacy information, and achieve the initial design purpose of the system.
