任何好的CAPTCHA推荐？ [英] Any good CAPTCHA to recommend?

问题描述

在Google搜索之后，我发现有很多CAPTCHA实现
PHP中的
可用。我想要一个不能（轻松）OCR能力，或者

否则可以破解。开源或商业并不重要。任何

的建议，或者特定的一个分享经验？


我在留言簿上收到了很多垃圾邮件条目，并希望保护它。 br />
我会要求用户在接受输入之前解决CAPTCHA。不过，
可能会使用CAPTCHA来保护其他表单提交。

After a Google search, I see that quite a few CAPTCHA implementations
in PHP are available. I''d like one that''s not (easily) OCR-able, or
otherwise crackable. Open source or commercial is not important. Any
recommendations, or experience with a specific one to share?

I get a lot of SPAM entries on a guestbook, and want to protect it.
I''ll require users to solve a CAPTCHA before their entry is accepted. I
might use CAPTCHAs to protect other form submissions, though.

我的经验是CAPTCHA无法正常工作。

我收到很多垃圾邮件。

My experience is that CAPTCHA doesn''t work.

I get lots of spam though.

不要使用CAPTCHA。让用户注册您的服务并检查他们的

电子邮件地址是否有效.CAPTCHA无法访问且不能跨浏览器

兼容。

Don''t use CAPTCHA. Make users sign up to your service and check their
e-mail address is valid. CAPTCHA is inaccessible and not cross-browser
compatible.
