Design And Development Of Internet-based Computer Anti-theft Tracking System

Computer anti-theft tracking system has not yet been widely applied nowadays, while a variety of serious consequences due to the loss of computer are unbearable to the computer users. Therefore, design and development of internet-based computer anti-theft tracking system becomes very necessary.In this paper, taking the background of "Internet-based computer anti-theft tracking system platform construction project" by Fuzhou Public Security Bureau(this project has been approved by the specialists of Fuzhou Digital Construction Leading Group Office.), through in-depth study of the basic theory and key technology applied to the development of this system, two kinds of key technologies of computer on-line tracking and data comparison are proposed and solved.Finally, through the functional design of the system, an Internet-based computer anti-theft tracking system of multi-level public security departments information sharing and service interworkingare realized. The main research work is as follows:1. On the basis of existing domestic and foreign computer anti-theft tracking technology research and analysis, analyze theories and technologies (such as J2EE system structure, MVC system structure, Active technology, XML, SOA, Web Service, database) required by computer anti-theft tracking system and provide support for system design,development, operation.2. Introducing computer anti-format technology and program covert operation technology into this system, propose computer on-line tracking technology and on-line data comparison technology, research respectively from two aspects of technical principles and implementation process,achieve client tracking program anti-format and covert operation, and server listening for client tracking requests, achieve feature information data comparison of suspected stolen computer.3. Based on the above theories and key technologies, design the overall computer anti-theft tracking system and design the database.For the 7 subsystems (computer information marking subsystem, secondary market management subsystem, alarm platform subsystem, location tracking subsystem, SMS management subsystem, backup management subsystem and system management subsystem), design in detail from the three aspects of system function, service process and service data flow. And taking the example of owner registration module, design module-involved window object controls, window event(function), input items, output items, program logic, classes and interfaces.4. The system applies B/S frame, Debian GNU/Linux operation system platform and JAVA, JSP, C language to finish the development. The system data amount and system performance has been tested. The system has also been applied for demonstration in Fuzhou. Basing on this system, several computer theft cases have been uncovered, which has good application result.
