一词重新拼写？ [英] one word recaptcha?

问题描述

您好，我看到Facebook使用的是Recaptcha，但是在他们的注册页面中，他们可以显示一个验证码字词，而不是两个，然后我注意到repcatcha仅验证第一个字词，而第二个字词充当了虚拟字符，问题是我们能以某种方式告诉Recaptcha仅显示一个单词吗？而不是两个？

hello i see facebook is using recaptcha, but somehow in their register page, they can show one word of captcha instead of two, and then i notice that repcatcha validate only the first word, and the second word acts as a dummy, the question is can we somehow tell the recaptcha to just show one word ? rather then two ?

推荐答案

否。

但是，如果计算机无法读取这样的
验证码，怎么办系统知道谜题的
正确答案吗？以下是
的操作方式：将每个不能被OCR正确读取的
的新单词与另一个答案已经为$ b的单词
一起提供给
用户$ b知道。然后要求用户
读两个单词。如果他们解决了已知答案的一个
，则
系统会假定他们的答案对于新的答案是正确的
。然后，系统将
的新图片提供给其他
人，以便以较高的
信心确定最初的
答案是否正确。

But if a computer can't read such a CAPTCHA, how does the system know the correct answer to the puzzle? Here's how: Each new word that cannot be read correctly by OCR is given to a user in conjunction with another word for which the answer is already known. The user is then asked to read both words. If they solve the one for which the answer is known, the system assumes their answer is correct for the new one. The system then gives the new image to a number of other people to determine, with higher confidence, whether the original answer was correct.
