Design And Implementation Of Digital Forensics System For Intelligent Terminal

With the rapid development and progress of mobile communication,multimedia communication and Android system,intelligent terminal based on Android has been widely used and widely used.Android intelligent terminals for people to provide voice calls,short messages,data transmission and other functions to improve the convenience of people's lives,but also for criminals using Andrews intelligent terminals for criminal activities to provide a new tool to use intelligent terminals to send and receive criminal information,It can also snoop,spread the privacy of others,so the intelligent terminal has become a new criminal tool in the mobile communication era,and the criminal activity is more rapid and hidden,the impact of a wider range,so the development of digital forensic intelligent terminal system is particularly important.In this paper,the theory and model of digital forensics for Android smart terminal are analyzed in detail.The key technology of the development and implementation of digital access system is described,which are Net Beans IDE,Java programming language,Spring technology,MVC technology,SQL Server database technology.Secondly,the paper analyzes the requirements of the system and derives the logical business functions of the system,which are digital acquisition function,data analysis function and post-processing function.A good business process flow is constructed,and the system security,consistency and reliability are analyzed..Then,the paper describes the design principles of the system,from the overall process of the system,the logical structure of the design,while the system's key functional modules in detail the design,given the core function of each system code files.Finally,the paper describes the system implementation environment,and gives the key technology of system implementation.It analyzes the function realization of each key system,which is the algorithm flow of data acquisition realization,data analysis realization,database realization and data verification.Part of the system running screenshots.Digital forensics system can effectively meet the intelligent electronic terminal Andrews access,analysis and processing functions,improve the efficiency of handling public prosecution law.
