Special Case Investigation And Research Under The Background Of Information Technology

Under the background of the rapid development of information technology,both the criminal situation and the investigation and crackdown means have changed greatly.While the number of criminal crimes is increasing year by year,the crime presents the characteristics of professionalism,network,intelligence,industrialization and cross-regional culture,and the difficulty of criminal investigation work is greatly increased.Criminals use convenient information technology means to commit crimes,and the crime efficiency has been greatly improved.With the popularity of the Internet,the proportion of non-contact crime has also increased dramatically.This kind of crime implemented with the help of cyberspace is characterized by low crime cost and strong concealment.Crime information makes the crime location no longer confined to the physical space,but expands to the virtual space.Virtual cyberspace provides convenient conditions for suspects to escape,leading to victims spread all over the country.However,the new crimes of high intensity,high difficulty and high complexity require more police resources input,which further aggravates the tension of police resources in China.In the face of such a high-pressure crime situation,the traditional special case investigation organization form shows many defects and deficiencies,and it is difficult to adapt to the attack needs of the new period.Although the special case investigation work has formed a relatively mature case handling mode in practice,the theoretical research is relatively scarce,and a relatively perfect system has not been formed.The special case work will be carried out in the form of a temporary special case group.Due to the lack of a mature guarantee mechanism for the special case investigation,the enthusiasm,responsibility and execution of the investigators of the task force will be greatly reduced.The full application of information technology in the special investigation activities can effectively improve the investigation efficiency and thus reduce the investigation cost.Under the background of information,the optimization of special investigation system is conducive to improving the efficiency of special investigation and giving full play to the advantages of special investigation in the information age to meet the needs of fighting crimes under the new situation.Make full use of the dividends brought by the information age,apply the information technology to the special case investigation work,and transform it into a realistic public security combat effectiveness.The introduction part expounds the origin and significance of the topic and the status of research at home and abroad,and forms the writing ideas by consulting relevant materials.The first chapter is about the basic theoretical problems of special case investigation,which clarifies the nature,concept and characteristics of special case investigation.By comparing and analyzing the views of scholars,the connotation of project investigation is clarified,so as the theoretical basis of the subsequent content.The second chapter discusses the influence of information on crime and special investigation,thus introducing many problems in special investigation activities.The influence of information on crime includes crime extension to virtual space,diversified crime means,significant reduction of crime cost,increasing proportion of non-contact crime;information influence on project investigation changes from passive to active,small scale,change in the scope of cases,and high expansion of project investigation information resources.By combining some actual cases,analyzes the current situation of the current project investigation,analyzes the problems existing in the project investigation practice,such as: project investigation start not standard,astonished investigators select random,organization command and project requirements do not adapt,the allocation of investigation resources and project investigation requirements do not match,overlapping between projects,etc.Through the research and demonstration of the basic theory of special investigation and the above problems,the third chapter puts forward the optimization ideas of changing the thinking of special investigation,improving the organization process of special investigation and improving the guarantee mechanism of special investigation.The ultimate goal of improving the organization process and related system of special investigation is to explore a new way to improve the efficiency of special investigation,in order to inspire and benefit the standardization of special investigation.
