Design and implementation of investigation auxiliary platform based on Hadoop

Abstract:
Based on big data technology, under the Hadoop basic framework, relying on HDFS, MapReduce and other components to complete the storage and operation of a large number of video image files in modern case investigation, and combined with Java Web application development technology, SSH architecture is used to realize the design and development of investigation assistance platform. The system function covers the evidence collection link of case investigation, and mainly includes functional modules such as portal home page, case comprehensive processing, view comprehensive management and so on. With the help of big data technology, it realizes the distributed storage management of video images and the video analysis, research and judgment in the process of case investigation, greatly improves the query and retrieval efficiency of data information in the process of case investigation, provides necessary technical support for case investigation, realizes the function of auxiliary investigation, and makes a good attempt for the construction of public security informatization in our country.
