Design And Implementation Of E-evidence Cloud Storage Platform For Police

We have entered the era of big data at present,The sustained development and improvement of computer technology at home and abroad?The development of computer technology has stimulated the Traditional industry and traditional technology transformed.In this article take the criminal investigation work for example?E-evidence obtained by investigative technique increasing,but lack of effective means and methods to save.It cause a lot of valuable E-evidence loss and often cause legal disputes.How to save E-evidence has become a common problem troubling Grass-roots law enforcement units.In this article,on the basis of investigation through computer technology and the demand of Grass-roots law enforcement units.Development “E-evidence cloud storage platform for Police” employ development framework by Struts Spring Hibernate and Hadoop open source cloud computing.First we have brief introduction on the Architecture of the platform,Operation mode,Safety,development environments of Hadoop.And its feasibility of using Hadoop cloud storage platform to store E-evidence is analyzed.Secondly we have analyzed the work responsibilities of department of the public security branch and the law enforcement process.Design the structure of “E-evidence cloud storage platform for Police”Thirdly Development “E-evidence cloud storage platform for Police” employ development framework by Struts Spring Hibernate.Implement the following main functions:User login,File management,Back-stage management,System monitoringFinally a performance test has been carried out to confirm the feasibility of the platform.Test the function of login,File upload,File download,Cluster management,System robustness.The test results reached the expectation.
