Video Content Supervision System Design Based On Analysis Of Steganography

With the rapid development of Internet,video has become important way of rapid access to information for people in daily life.Video is used to spread useful information,at the same time,also spread bad information.Video information security problem is becoming more and more important.At present,there is some research in the area of network video content regulation and governance,network video content regulation and governance research based on the analysis of the video steganalysis is much less.Based on the research of video steganalysis technique,this paper designs and develops a video content supervision system based on the video steganalysis.The main research content includes the following several aspects.First of all,this thesis has carried on much research in the area of the video processing technology and the existing video steganography and steganalysis method.Summarize the advantages and disadvantages of existing methods,and select the steganography and steganalysis based on motion vector analysis method as the key technology in video content regulation.To fufill the requirements of company's integrated information platform,this thesis puts forward a method of static and dynamic dual regulation,listen and supervise the video content from the center of the video files and RTP data packet transmission in the gateway.Secondly,in view of unction and performance requirements for this video content regulation system,design overall technical architecture and main function modules(including:Video data acquisition module,Video Steganalysis module,Analysis and processing module).Video data acquisition includes static acquisition and dynamic acquisition.Static acquisition:get video data from file center;Dynamic acquisition:grab network packets from the gateway,identify the RTP packets,and restore RTP video data,as the analysis video data source.Through analyzing Video Steganalysis module and analysis and processing module,analysis and processing.Through the adoption of content filtering and blocking to protect the video data of integrated information platform transmission safely and reliably.Finally,this thesis takes the comprehensive test for the prototype system of video content supervision,and display the key pages,Then analyze the key function modules test results,as well as the main performance test results.
