The Practical Dilemma And Breakthrough Of Big Data Investigation

Now is the era of data explosion,our clothing,food,shelter and transportation traces can be recorded in the form of data,mass data makes data statistics,mining,analysis possible So big data is widely used in transportation,commerce,finance,shopping and other industries.Compared with other fields such as commerce and finance,the application of big data in the field of investigation started relatively late,in recent years,big data in the field of investigation,but the development speed is very fast.All the local investigation organs are committed to the construction of big data investigation system,the use of massive data information in the investigation activities,the use of big data for data mining,data analysis,crime portraits to help deal with cases.With the development of big data investigation,the academic research on big data investigation is increasing and deepening.This paper discusses the big data investigation from four aspects.First of all,from the concept of big data,characteristics and its application of big data analysis,and then the introduction of big data into the investigation is discussed.To clarify the definition of the concept and scope of big data investigation,this paper explains the concept of big data investigation from the aspects of thinking idea,system mechanism,concrete behavior method and so on.Then,combined with the application of big data in the field of investigation,the application status and practical value of big data analysis,the advent of big data era to the investigation has brought a qualitative leap,with great practical value.The use of big data can optimize the choice of investigation ways,promote the application of multi-thinking in investigation,expand the application possibility of active investigation,especially the correlation analysis and predictive function of big data can improve the efficiency of investigation To make the investigation more extensive and deep.Therefore,big data is widely used in the links of criminal information collection,Criminal Information Research and judgment,and the arrest of criminal suspects,etc.It plays an important role in expanding the sources of intelligence,improving the research and judgment technology of criminal information,and promoting the upgrade of the files of the investigation and synthetic warfare.Big Data has brought a lot of innovation and change to the investigation work,and some people will have the view that "big data investigation can do anything",but ignore the practical predicament that it may face.In fact,the application of big data in investigative work still has a lot of places to be perfected.Therefore,this paper discusses the practical difficulties of big data investigation,including the limitations of the big data itself,such as the promiscuity and asymmetry,the inability to link up with the traditional investigation,and the inability to meet the requirements of judicial proof Lack of legal regulation of big data investigation and so on.Finally,this paper puts forward some corresponding suggestions,such as promoting the construction of the database,integrating the big data investigation with the traditional investigation,clarifying the legal regulation of the big data,in order to help the investigators better use the big data tools to improve our detection capabilities.
