Chinese-English Translation:

验证码(CAPTCHA)是一种区分用户是计算机还是人的公共全自动程序。可以防止:恶意破解密码、刷票、论坛灌水等等,问题可以由计算机生成并评判,但是必须只有人类才能解答。

Captcha (captcha) is a public automatic program which can distinguish the user from the computer or the human. Can prevent: malicious password cracking, swiping tickets, Forum irrigation, etc., questions can be generated and judged by the computer, but only human can solve them.

验证码(CAPTCHA)是“Completely Automated Public Turing test to tell Computers and Humans Apart”(全自动区分计算机和人类的图灵测试)的缩写,是一种区分用户是计算机还是人的公共全自动程序。可以防止:恶意破解密码、刷票、论坛灌水,有效防止某个黑客对某一个特定注册用户用特定程序暴力破解方式进行不断的登陆尝试,实际上用验证码是现在很多网站通行的方式,我们利用比较简易的方式实现了这个功能。这个问题可以由计算机生成并评判,但是必须只有人类才能解答。由于计算机无法解答 CAPTCHA 的问题,所以回答出问题的用户就可以被认为是人类。

Captcha is the abbreviation of “completely automated Public Turing test to tell computers and human beings”, which is a kind of public automatic program to distinguish the user from the computer or the human. Can prevent: malicious password cracking, swiping tickets, Forum irrigation, effectively prevent a hacker to a specific registered user with a specific program brute force to try to log in. In fact, using verification code is now a common way for many websites. We use a relatively simple way to achieve this function. This question can be generated and judged by computers, but only humans can solve it. Since computers can’t answer captcha’s questions, the user who answers the questions can be considered human.

验证码这个词最早是在 2002 年由卡内基梅隆大学的路易斯·冯·安、Manuel Blum、Nicholas J.Hopper 以及 IBM 的 John Langford 所提出。卡内基梅隆大学曾试图申请此词使其成为注册商标, 但该申请于 2008 年 4 月 21 日被拒绝。一种常用的 CAPTCHA 测试是让用户输入一个扭曲变形的图片上所显示的文字或数字,扭曲变形是为了避免被光学字符识别(OCR, Optical Character Recognition)之类的电脑程序自动辨识出图片上的文数字而失去效果。由于这个测试是由计算机来考人类,而不是标准图灵测试中那样由人类来考计算机,人们有时称 CAPTCHA 是一种反向图灵测试。

Captcha was first coined in 2002 by Louis von ANN of Carnegie Mellon University, Manuel Blum, Nicholas J. hopper and John Langford of IBM. Carnegie Mellon University tried to apply for the word as a registered trademark, but the application was rejected on April 21, 2008. A commonly used captcha test is to let the user input the text or number displayed on a distorted image. The distortion is to avoid losing effect when the computer program such as optical character recognition (OCR) automatically recognizes the text and number on the image. Since this test is conducted by computers instead of the standard Turing test, captcha is sometimes called a reverse Turing test.

为了无法看到图像的身心障碍者,替代的方法是改用语音读出文数字,为了防止语音辨识分析声音,声音的内容会有杂音。

In order to prevent speech recognition and analysis of sound, the content of voice will have noise.

大多数网站的验证码都是需要点击一下填写框,然后会自动弹出验证码图片。由于验证码是随机产生的,有很大几率会出现无法清楚识别的验证码图片,所以需要注意的是,一般网站都会有相应的提示,如“看不清,换一张”等,如果没有提示,则直接点击当前的验证码图片,可以完成验证码的更换。

Most websites need to click on the fill in box, and then the captcha image will pop up automatically. Since the captcha is generated randomly, there is a great probability that the captcha image can not be clearly identified. Therefore, it should be noted that the general website will have corresponding prompt, such as “can’t see clearly, change one”, etc. if there is no prompt, you can directly click the current captcha image to complete the replacement of the captcha.
