The design and implementation of security defense system based on Android

Abstract

With the rapid development of mobile Internet technology and the popularity of smart phones, more and more people have taken the smart phones as the necessities for mobile work, online learning, communication and entertainment. Smart phones are quietly changing our work and lifestyle. Android system has occupied large market share because of its powerful function and easy development features. Due to the open-source feature of Android platform, hackers can easily find and crack its vulnerabilities. Therefore, Android system has become the preferred target for hackers' attacks. However, according to the 2016 mobile security report released by 360 mobile guards, more than 99% of mobile phones are vulnerable. The security of Android has drawn more and more attention in recent years, and engineers are working tirelessly to improve it. In summary, this paper provides a solution of Android-based phone security defense system. It first introduces the system architecture of the security defense system based on Android and clarifies the design of system function modules, then describes in detail the implementation of key technologies that including the use of MQTT (Message Queuing Telemetry Transport) protocol, fingerprint recognition and privacy file encryption, and last summed up some deficiencies of system. After the completion of the system, it works well and has some guiding significance for the development of security projects based Android.
