Design And Implementation Of Automatic Invigilation System

With the development of society and economy,school and university have better hardware facilities,especially computer labs for computer education.This also makes the paperless examinations begin to popularize.The paperless exam has many benefits,such as normalize the form of exams,save the exam resources,improve the efficiency and extend the kind of question.It also provides students with result analysis and good problem-solving experience,all of which are traditional exams cannot fulfill.However,due to the properties of the computer platform and the complexity of managing a computer lab,the paperless examination also brings new challenges to school.In the paperless examination process,the violation of the examination discipline no longer includes simple ways such as look at other people's answers,bring materials without permission,but also includes the use of electronic media,connected to outer networks,use some forbidden software and other new ways.These actions are hard to track,so therefore even if the teacher has good training,it is still very difficult to detect.We introduces the design and implementation of an automatic invigilation system.Though the information gathering module,evidence preservation module,remote control module and encryption transmission module,we can monitor the examinees'activities and keep the evidence without strictly depending on the computer environment.We also make the system to adapt high concurrency and it performed well in real situation.
