Research On Theory And Application Of Technical Investigation Measures

Technical investigation measures as organs of investigation is a special investigationmeans is with modern science and technology innovation as well as the development ofscience and technology is gradually used in criminal process produced, high-tech crimeincreased as well as in combating crime in the process of investigating the increased difficulty,also make the investigation organ gradually introduced a new technical means and methods tocombat and prevent crime. The investigation organ from the reverse of investigative conceptand case investigation to reverse and forward investigation of both the investigative modealso resulted in the rapid development of technical investigation measures. Throughout theworld, in the investigation of crimes in the process of using the technical means to detectcrime is a kind of trend, this helps to save the cost of justice and judicial resources is moreconducive to improving the efficiency of the crime and the realization of judicial justice. Withthe progress of science and technology of new crime means being applied to the drug crime,organized crime and other crimes, also makes countries will new technology and detectionmethod are applied to these major crime investigation. And with the measures of technicalinvestigation in China’s criminal investigation in the process of practice is more and moreapplied and development, in the theoretical circle, is also more and more attention.This paper is divid into four parts of the technology development and application ofinvestigation measures make the preliminary discussion, on the foreign technical investigationmeasures and the application of legislation on the basis of introduction our country technicalinvestigation measures legislation present situation as well as in the investigation of crimes inthe operation process of the specific application of investigation measures.The first part, an overview of technical investigation measures, this part focuses on thetechnical investigation measures the meaning exactly defined, and the measures of technicalinvestigation is described. After the argument in now high-tech crime situation measures oftechnical investigation basis of existence, namely the crime of high-tech detection methodimprovement. Then the technical investigation of similar and related concepts were initiallydefined, namely technical investigation measures and detection technology, technologyinvestigation and technical investigation measures and secret investigation and measures of technical investigation and the right of privacy in relation to do some analysis anddemonstration.The second part, technical investigation measures of development, this part mainlyintroduces the technical measures to detect the history and development of the process. Firstintroduced the investigating authorities in the investigation of criminal cases in the course ofapplication technology investigation measures and significance, introduced the secondtechnical investigation measures of the development and the application process, and thenintroduces abroad in China and the measures of technical investigation and the application ofprovisions of the current situation, on the basis of the analysis of Chinese and foreigntechnical investigation measures application and comparison of the regulations.The third part, the application of technical investigation measures, this part introducesthe measures of technical investigation of specific application means and methods and theapplication of technical investigation measures of case examples, for electronic eavesdropping,Micronesia shoot secret recording, electronic surveillance, GPS satellite positioning, infraredthermal imaging system, and mobile phone positioning technology and police the networkapplication is introduced, in the specific measures on the basis of the investigation organusing measures of technical investigation of crime investigation process of facing problemsare discussed in this paper. In the final analysis of existing technology on the basis ofinvestigation measures, with the development of science and technology may also in criminalinvestigation process and the application of technical investigation measures are introduced.The fourth part, technical investigation measures and problems in application process,this part summarizes above technical investigation measures based on measures of technicalinvestigation on problems in application are summarized and analyzed, while putting forwardthe question on how to solve the existing problems and put forward some theoreticalproposals.In this paper, as a result of the information obtained is limited, for the investigationorgan in the criminal process in the specific application of technical investigation measures,as a result of these measures are related to state secrets for many reasons the investigationorgan rarely announced specific measures used, the author only in the specific practice andthe learning process by contact and according to the limited information gain measures discussed, so the measures of technical investigation is also very limited. This is the authorthe work in the future as well as the learning process needs further research fields.
