Research Of Investigation Innovation Under The Background Of Big Data

In the age of big data,there is no bystander.The rapid development of information and network technology makes big data a research hotspot in the current academic and practical circles.The explosive increase of data and the accompanying various problems bring human society unprecedented opportunities and challenges.In the domain of criminal investigation,big data criminal investigation has become a hot research field.On the one hand,the processing,analysis and sharing of big data,together with its advantages of diversity and application synergy,repeatable exploitation and decision-making assistance,have triggered a series of revolutions in ideas,benefit,thinking and organizational modes of criminal investigation,which further caused the change of detection modes.But on the other hand,benefits and risks coexist.While enjoying the huge convenience and wealth of big data,we have to bear the subsequent risks,whose concrete result in the criminal field is making the latter generate new diversified,activated,dynamic and organized changes and trends.All these changes and trends are sure to give rise to a series of changes in the field of criminal investigation.The big data criminal investigation is generated and developed under the dual function of epochal progress and criminal situation.It is of great necessity to clarify the interaction of era development,criminal situation and criminal investigation system in the theoretical research and application of big data criminal investigation.It can not only define the necessity and feasibility to develop big data criminal investigation,but also points out some misunderstanding in the current practice,thus pointing out the right direction for the application and development of detection practice.In the practical research of criminal investigation,based on the two basic functions of criminal investigation,that is,criminal detection and crime prevention,this thesis discusses the application thinking,suitable targets and key emphasis in work of big data in the field of detection.In this way,a systematic system of big data criminal investigation research established in crimes as a whole and balancing theories and practice,thus making some contributions to the basic theoretical research and innovation of criminal investigation.This thesis is divided into 5 chapters.Chapter 1 is introduction,which mainly introduces the research background and relevant research status of big data criminal investigation.Meanwhile,it also clears up the research method,research significance and innovation points of the thesis.Chapter 2 is the summary of big data criminal investigation,which mainly defines and summarizes detection from the visual field of big data in terms of concept,connotation,boundary,function as well as basic theories.Chapter 3 is an important chapter for innovation.Itis the theoretical principle of big data criminal investigation,in which the author constructs a three-level dynamic system including factors of era,crime and detection.And meanwhile,the author also has a discussion on the interaction of big data,crime system and detection system on different levels,thus further exploring causes of the difference in the adaptivity and regularity of detection and crime.In this way,it is helpful to find out methods of narrowing such differences and improving detection efficiency under the background of big data,that is,proactive criminal investigation and accurate criminal investigation with big data.The fourth chapter and the fifth chapter are the practical application of big data criminal investigation.Chapter 4 is about proactive criminal investigation with big data.It mainly analyzes and discusses critical issues in proactive criminal investigation,believing that the starting point of proactive criminal investigation is criminal threat,and that the impetus of detection originates from the description of criminal threat based on various types of intelligence information.In terms of functions,it is mostly characterized by the function of predicting and preventing crimes,and the final purpose is to cut down incidence of crimes.This chapter mainly analyzes and expounds the working principles,thinking and practice difficulties of proactive criminal investigation.Chapter 5 talks about accurate criminal investigation with big data.It mainly offers a systematic discussion of accurate criminal investigation,believing the starting point of criminal investigation is criminal behavior.It is a process that after the occurrence of criminal behavior,investigators accurately find out the breakthrough points,uncover the cases and capture the suspects by dealing with the grasped data.This chapter mainly analyzes and discusses criminal types applicable to accurate criminal investigation,major features,feasibility and necessity,implementation paths as well as the organization mechanism to guarantee the maximum benefits of accurate criminal investigation.
