Design And Implementation Of Electronic Evidence Forensics Management System For Police Department

This paper discusses the security of electronic evidence inquisition software design and implementation of management system. The purpose of the system is facing the increasing computer crime cases of electronic evidence in the acceptance, investigation, analysis, maintenance, supervision and other aspects of the challenges faced by the management, and improve the previous in electronic forensics management tool is not comprehensive enough and adaptability is not flexible enough.This paper first outlines the development of theoretical basis of the system, technology basis and application background review, the next inspection requirement analysis management system for public security of electronic evidence is discussed, focuses on the analysis of the most commonly used pre approval module, module, module, security module supervision requirements, and established the model of the main case. Based on the demand analysis as a guide, this thesis discusses the design method of software design of the system architecture, database design and main modules, finally, from a procedural point of view the security electronic evidence inquisition implementation and test case management system, gives some running examples and test cases.On the basis of fully studying the key factors needed for the implementation of the project, combined with the current business model of the public security organs, the function subsystem is divided. And use the B/S structure, LAMP platform and workflow technology, solve the public security organs inspection business information flow and data exchange activities in all kinds of complicated problems in E-evidence, significantly enhance the efficiency and standardization of our Bureau Inspection Management of electronic evidence, especially the entrusted units and law enforcement and supervision departments and master of electronic evidence inspection schedule and evidence preservation state, is conducive to improve the operation efficiency and inspection procedures for inspection of electronic evidence identification laboratory standardization.At present, this system has been put into trial operation, the operation results show that the system has good performance, reliable operation, convenient use, improve the public security organs electronic evidence inquisition laboratory efficiency, enhance the ability to combat crime, to achieve the desired results.
