要验证或不验证[关闭](To captcha or not to captcha [closed])

我想知道您如何为注册表单添加验证码机制？

我注意到许多网站在注册表单中不使用验证码机制（例如： http : //djdesignerlab.com/2010/04/14/25-cool-sign-up-and-login-form-designs/ ）。

我想打开这个主题来看看人们的想法。

我一直认为我们应该尽可能保证我们的表格安全，但从另一个角度来看，有很多用户在注册页面填写验证码并不需要太多的耐心。

- 您认为将此机制添加到注册页面可以大幅减少长期注册用户的数量吗？

- 在注册页面不能包含这种机制有多危险？

I would like to know what do you think about adding captcha mechanisms to registration forms?

I notice that many sites don't use captcha mechanisms in their registration forms(examples: http://djdesignerlab.com/2010/04/14/25-cool-sign-up-and-login-form-designs/).

I would like to open this topic to see what people thinks.

I always thought that we should make our forms as secured as possible, but from another point of view there are many users out there that don't really have to much patience to fill a captcha at a registration page.

-Do you think adding this mechanism to a registration page can drastically drop the amount of registered users at long term?

-How dangerous can it be not including this mechanism at a registration page?

最满意答案

我在我的系统上设置验证码有一个主要原因：要知道注册或注册的用户实际上是人。 不要忘记，验证码不仅用于注册和/或登录安全检查。 例如， 如果它在很短的时间内感觉到相同问题上的编辑太频繁，就会发生验证码错误。 在这种情况下，验证码是检查编辑器是否是人而不是机器人。

从本质上讲，你必须做出一个很好的决定，你想在哪里使用captcha（如果你打算使用它）以及它如何用于你的目的。

希望这可以帮助。

I setup captcha on my system for one main reason: To know that the user who register or is registered is actually human. Don't forget that captcha is not only used for registration and/or login security checks. SO, for example, have captcha if it senses that there's too frequent edit on the same question/answers in a very short time span. Captcha, in this case, is a check to see if the editor is human instead of a robot.

In essence, you have to make a good decision of where you will like to use captcha (if you're planning to use it) and how will it serve for your purpose.

Hope this helps.
