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.

   Although online classes have existed for more than a decade ，the concern over cheating  has become sharper in the last year with the growth of "open online courses." Private colleges，public universities and corporations are jumping into the online education field . spending millions of dollars to attract potential students，while also taking steps to help guarantee  honesty at a distance.

Aside from the web camers, a number of other hight-tich methods are becoming increasingly  popular Among them are programs that check students’ identities using personal information,such as the telephone number they once used.

     Other programs can produce unique exam by drawing on a arge list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones ,As in many university classes ,term papers are scanned aganinest some large Internet data banks for cheating.
