While Jennifer was at hose taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer’s Los Angeles apartment , the monitor in Phoenix tracked how frequently her eyes moved form the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked — remotely — to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?
In the battle against cheating , this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven’t just searched the Internet to get the right answers.
