Polygraph Technology Application Research Of Duty Crime Investigation Practice

With the progress of science and technology, polygraph technology today has tend to mature, the application in our country's duty crime investigation practice more widely and frequently, the effect is becoming more and more significant, which is the attorney industry favor. But, because of the lie detector technology applied in judicial practice, especially the duty crime investigation in practice time is shorter, polygraph professionals lack, hardware construction is not perfect, and the lack of law related to all these problems lie detector technology application caused great impact. Lie detection technology is applied in our country, the author of this paper, therefore, the duty crime investigation practice, principle of polygraph technology and method system is introduced, combined with lie-detection technique is applied to the typical cases of duty crime investigation practice, necessity and reality of the application of polygraph technology effect is analyzed. And in view of the current detecting technology applied in the practice of duty crime investigation objective problems, put forward from the legislation for lie detection technology and its conclusion accurate angles such as legal position to regulate and perfect the idea of polygraph technology application, in order to make lie detector technology to play a more active role in the practice of duty crime investigation.This article mainly USES the following research methods:one is the literature reading method. With the aid of the library, network and so on various channels to obtain about the polygraph, development and application of information technology, read documents, newspapers and magazines, paper journals at home and abroad for lie detection technology are reviewed, such as master of polygraph technology application in judicial practice. Through to the reference literature, periodicals such as reading, learned scholars and other researchers for lie detection technology evaluation and views, and thus provide theoretical reference and support for their writing. Second, the comparative research. Compared to foreign polygraph technology application and the practical application of polygraph technology in our country, summarizes the polygraph technology in our country's duty crime investigation practice the role and the insufficiency. Three is the practical research method. Use myself in procuratorial organs work convenience, collect the polygraph technology applied to the practice of duty crime investigation research materials and actual case studies, and then to collect and analysis, provide real and reliable basis for the paper writing.This paper is divided into five parts:the first part, introduction to the theory of lie detection technology, from the meaning of the polygraph technology, introduces the principle, characteristics and method, and contrast analysis of polygraph technology in abroad and domestic development and application of history. The second part, this paper discusses polygraph technology applied in our country should have the condition of duty crime investigation practice, a program using a polygraph and which factors will affect the conclusion of lie detector technology. The third part, it is lie detector technology applied to the analysis of duty crime investigation practice, how to lie detector technology applied in the duty crime investigation has the workability and necessity is analyzed, and combining the relevant case analysis lie detection technology was applied to the reality of duty crime investigation practice. The fourth part, the polygraph technology applied to the problems existing in the practice of duty crime investigation, respectively from different point of view of problems existing in the practice are discussed. The fifth part, on how to perfect the polygraph technology applied in duty crime detection is presented, mainly from the attaches great importance to the cultivation of talents, strengthen the lie detector hardware construction, strengthening the legal supervision on the application of the polygraph and establish the status of polygraph conclusion from the law Angle is discussed.
