Cloud Storage Research On Criminal Investigation Video Data

With the modernization of the city's economic development,the necessity of building a harmonious society growing more increasingly demand for video surveillance.Exponentially enhance the definition of the video cameras and other video capture devices.The monitoring large is increasing year by year.And the demand of computing is increasing,however,the development of cloud computing gives a new way to video monitoring system.Therefore,the direction of this research is to present a large-scale high-definition video surveillance system based on cloud computing.You can store massive privatization of read-only storage cloud storage technology forensic video data on the cheap untrusted nodes forensic video data,and to provide efficient and reliable access.Use of cloud storage technology to store video forensic data storage costs can not only greatly reduce video forensic data,and video forensic data can be convenient and efficient access.Contents of this subject has good practical significanceAccording to the cloud computing technology introduction and demand analysis of the video monitoring system,this paper presents a new architecture of video monitoring system based on cloud.And then it gives deep analysis and design to the system.Finally it completes the security system design and the system test,and also gives a conclusion.
