专抓考试作弊的新技术 To catch a test-taking thief (with technology) Now that American education has entered the era of the MOOC -- the Massive Open Online Course -- the opportunity for cheating appears greater than ever. The omniscient Google search engine is never more than a few keystrokes away for the computer-bound. So how can a proctor possibly manage the far-flung multitudes, let alone smoke out cheaters taking tests across the Internet? 美国的教育界已经迎来大规模开放网络课程（MOOC）风起云涌的时代，网上考试作弊现象也由此前所未有地猖獗起来。在电脑操控的世界，想呼唤万能的谷歌（Google）有哪些信誉好的足球投注网站引擎，也不过就是轻轻几下敲击的距离。那么，网络课堂的督导者们要怎样管理遍布各地的学员大军？要是管理众多学员的有效方法还无法确定，就更别提怎样扑灭作弊者在整个互联网世界燃起的熊熊大火了。 Using technology, of course. While proctoring services via webcam and plagiarism-detecting software have been around for several years now, an India-based startup has come to America -- Silicon Valley, obviously -- with automated, algorithm-based techniques for netting cheaters that the company claims are even more sophisticated and foolproof. Essentially, if you try to pull a fast one, your computer will rat you out. 当然，上述问题用科技手段就能解决。利用网络摄像头和检测抄袭的软件提供学监服务也不是新生事物，这个产业已有多年的根底。一家总部位于印度的业内初创公司Mettl已经杀入美国，入驻硅谷。虽说在搜捕作弊者方面只是“新人”，但Mettl拥有以计算机程式为依托的自动化技术，还自豪地声称，它捕获作弊者方式比传统做法更老到，甚至堪称万无一失。当然，有一条基本原则我们不该忘记：如果你想在参加网上考试时玩什么鬼把戏，你应试的电脑就会出卖你。 The online assessment company Mettl has incorporated a handful of technologies into its test-taking platform, creating, for the duration of an exam at least, a mini-surveillance state. 作为一家从事网上评估测试的公司，Mettl将多种技术融入了自家的测试平台，至少在一场考试所需的时间内便能创造一种小型监控环境。 Heres how it works: A test-taker signs on to Mettl and selects his/her exam from the sites library of pre-loaded tests. Facial and keystroke recognition technology verify the person that has signed in is the person they say they are, and the system records both the test-taker (through the webcam) and the test-takers screen throughout the test. 具体来说，监控环境是这样形成的：一名应试者先要在Mettl网站注册，然后就能在网站的考题库里挑选预先上传到网站的测试题。面部击键识别技术可以确认注册的应试者是否就是他们自称的那个人。不论是在应试者注册时网络摄像头拍下的应试者信息，还是整个考试期间透过电脑显示屏留下的应试者信息，系统都会悉数记录。 Mettls t
