webcam capture image from client and send to server randomly
<p>I have an online exam management system that requires to capture images or detected the student trying to cheat. I currently have support for uploading the images automatically to the server website from a local directory on the client machine. </p>

<p>The very environment in which students can use a Web browser and the Internet enables them to search the Internet and to communicate with others for help during the exam.</p>

<p>One proposal was to use a Webcam to prevent cheating by randomly transmitting pictures of students during online exams. However, several soundless pictures of a student do not
show what that student is doing or why he or she is doing it,or even if cheating is taking place through Web searching, the use of saved data, or chatting</p>
