Under The Background Of Big Data: Exploring The Pattern Of Proactive Criminal Investigation

At present,in the face of the situation of increasing types of crimes,the traditional investigation mode has been unable to meet the needs of today's crime fighting.With the development of big data,we can rely on big data to collect evidence and find out criminal facts.We can also rely on big data to stop crimes when crimes are still in the preliminary stage,which is especially applicable to terrorist crimes.In addition,we can rely on big data to deploy police forces in advance to prevent crimes.It can be seen that the investigation mode driven by big data is completely different from the means,ideas and methods in the traditional investigation mode.However,what kind of influence will big data technology have on China's investigation mode? Whether the reformed investigation mode can fight against criminal activities more effectively is a question worth further discussion and an important part of maintaining social stability.In view of this,the author to use big data to detect cases of typical cases,from the perspective of big data,the theoretical circle about investigation mode for reference,based on the practical work of in-depth research,deeply analyze the effects of big data to detect model,proposed from theory and practice to explore the data of the public security organ under the background of how to make use of big data technology to change traditional mode of investigation,after the change of active crime investigation mode can be more efficient,to this end,the author in the perspective of big data,put forward the idea of investigation mode change,to render investigation related theory research and practice.By using the methods of literature survey and comparative analysis,the author made a preliminary analysis and research on the active investigation mode under the background of big data.In addition to the introduction and conclusion,this paper is divided into three chapters.First,it summarizes the big data,clarifies the concept,features and functions of big data,and then expounds the impact of big data on the investigation work.Secondly,through the literature research in this paper,the active detection mode are discussed,and carried on the thorough analysis on the active detection model,clear the form,the paper expounds the dilemma encountered by traditional investigation mode,put forward the big data driven active detection pattern is the choice of our era,and further demonstrates the active investigation mode applicable object and the crime type.Finally,in this paper,the large data model in the practical application of active investigation,clear crime clue is the key to start the active detection mode,and some active investigation in actual combat mode of several intelligence analysis methods,hoping to lead investigators in thinking when in actual investigation,the author of a power for criminal investigation.
