Design And Realization Of The Material Evidence Management System

With the deepening of reform and opening up and development of the market economy, human, financial, and material flow in large quantity leads to increasing complexity of the situation of public order, and has put forward higher requirements for the public computer information construction and applications. The information construction of public security investigation is an important link of the "Golden Shield Project". To access to evidence has always been the starting point and final goal of criminal science and technology, and it is the foundation for the public security organs to fulfill law enforcement strictly, fairly and civilized. At present, the management level of material evidence is very limited. The means of management is lagging behind, and some even stay in a few years ago on the management model, with manual labor occupying a major position.The annual rate of unsolved material evidence is maintained at a high level. Such kind of management confusion led to a series of issues getting out of line. As a result, to use modern information technology to improve the management quality, realize technological management of scientific evidence, and make up the lack of work, so as to enhance the work efficiency is the only way.This paper analyzes the development background of the material evidence management system and the condition of research and development at home and abroad; describes the main problem the system need to address briefly, the overall business conditions and demand for technology and business needs in detail, introduces the detailed system design, software architecture design, network architecture design, security design and technology, technical routes, and also the function achievement of the system in detail, the resolve of the key issues of the main system and the function of each module.The key issues this article addressed are as follows:First, the realization of material evidence storage investigation management and the integrated management after storage. The series of chain business process management includes registration management, investigation respectively management and professional testing process management of the and so on. The realization of inquiry, borrowing, transferring, destruction of the material evidence management, as well as the statistical information, and chart analysis of the material evidence; Second, the application of workflow technology, which defines the work activities decomposed, allocates upstanding tasks, roles, rules and procedures for implementation and monitoring to improve the management and efficiency. It includes settings of workflow types, customized workflow, workflow node, and other settings;Third, the system involves important material evidence of public security departments, therefore, data security and reliability are very important, which runs through the entire process of the system building. System data access and modifying both require a unified identity authentication and authorization, to ensure data security.
