问题描述

我讨厌验证码，您认为有更好的解决方案

i hate captcha, do you think there is a better solution

推荐答案

您可以检查实用的非基于图像的验证码方法吗?

我早些时候问过一个问题需要建议/想法易于使用但安全的验证码

I asked a question earlier Need suggestions/ideas for easy-to-use but secure captchas

但是，如果由于验证码的存在而导致用户面临的困难而使您感到恼火，那么对此进行了很多辩论，人们仍在努力提出一种通用的解决方案，该解决方案甚至可以正常工作适用于非常受欢迎的网站.

However if you are irritated due to the difficulty faced by users because of the very existence of captchas, then there has been a lot of debate over this and people are still trying hard to come up with a universal solution which can work even for very popular sites.

您应该看到 http://nedbatchelder.com/text/stopbots.html 负验证码的实现.但是遗憾的是，据我所知，这对于特定于站点的垃圾邮件攻击(当您的站点非常流行时)仍然无效.作者说，他已经成功地将这些技术用于不太受欢迎的网站.最新的负面验证码的总体结论是，无论您使用哪种技术，垃圾邮件发送者都可以对他们的机器人进行编程，以使其在一定时间内如果定位到您的网站，就可以将其破解.当它变得非常流行时，他们可能会以您的网站为目标.但是您可以肯定使用它们，直到您的网站不太受欢迎为止.

You should see http://nedbatchelder.com/text/stopbots.html for implementation of Negative captchas. But sadly, this is not effective as yet for site specific spam attacks (when your site gets very popular) as far as I have understood. The author says he has been using these techniques successfully for less popular sites. The overall conclusion with the state-of-the-art negative captchas is that whatever technique you use, spammers can program their bots to crack it in some time if they target your site. And they will probably target your site when it gets very popular. But you can definitely use them till your site is not very popular.
