Design And Implementation Of Monitoring And Processing System On Mobile Phone Based On Android

Now we are embracing the era of fast technological and communication development with the mobile phone becoming increasingly popular.It has already become an indispensable part of our daily life.The mobile phone can act as tools not only for study and recreation but also for criminal activities.In recent years,criminals using mobile phones as their ways to transmit information is no news to us.Therefore,with the aim to find out the criminal activities,collect information and to crack down illegal activities relating to mobile phones,it is of great significance to monitor and analyze the personal information and input on mobile phone.The research on monitoring and processing system of mobile phone provides technical support for judiciary and detection.To this end,the paper researches and designs the monitoring and processing system on Android mobile phone,including the following three major aspects:1.The first step is to study relevant Android technology with the focus on the study and application of extraction mechanism of content in Android and broadcasting service.The requirement analysis of the system is accomplished on account of the system's need and detailed use case diagram and system flow diagram are designed to embrace the requirement analysis of Android.Requirement introduction acts as a key role in software design,for it is the prerequisite of subsequent system design.During the process of analyzing the requirement,several major functions of this monitoring system should be clarified,and then,system data flow and database needed are analyzed,in order to accomplish the analysis of system data flow and the establishment of database model.2.With specific system requirements can start of the summary design and detailed design of the system.According to system requirement analysis of the use case diagram and data flow diagrams,completed the overall design,the function of this system has been clear about the function of each case needs to be done.Then according to the overall design can put the system function modular is decomposed into several functional modules(including information extraction module,input module and monitoring module,network feed-back command message interception module),follow-up work completed the design of each module implementation,eventually integrated into a complete monitoring processing system3.Testing of the system.Through the design realized the Android based mobile monitoring processing system,need according to the system requirements for system respectively each functional design test cases to complete function test.With flash into the target cell phone test experiment,able to complete the command message interception delete function,and can effective to target mobile personal private information including SMS,contacts and call records and monitor input record,successfully achieved through the socket network communication back personal private information function,achieve the original intention of covert surveillance,make the target cell phone users.This research can improve monitoring and analysing the mobile phone of the suspects,it also can obtain the dynamic information of the phone remotely.Aftet the subsequent computer terminal updates and the subsequent processing module adds new function of analysis,it can be applied in the course of the investigation of cases,and it provide protection for combating crimes and protecting the security of the social.
