KeyCAPTCHA Unique Technologies
Instead of guessing symbols, our CAPTCHA offers visitors to complete an easy interactive task.
If KeyCAPTCHA hasn't been solved correctly, page refreshing doesn't take place that allows the user not to fill in the form repeatedly. It occurs since there is an initial checkup of CAPTCHAs in the KeyCAPTCHA servers before sending a filled-in form to the protected web server.
Our CAPTCHA also can be used even if your hosting provider blocks all outgoing connections.
Effective Anti-Spam Protection
The geo-cluster is used to operate KeyCAPTCHA service. Our geo-cluster includes the servers located in diverse European data centers. Some servers are in the special DDoS stable data centers in Switzerland to ensure trouble-free 24x7x365 mode service operation.
KeyCAPTCHA blocks spammers using anonymizers or anonymous HTPP proxies to distribute a hand spam.
There is no info of correct CAPTCHA solution in the visitor's browser.
CAPTCHA verification is processed by the KeyCAPTCHA servers.
Data transferring between your web server, the visitor's browser and the KeyCAPTCHA server is protected by a digital signature.
112 to 165 bit variable length password is used to generate a digital signature.
KeyCAPTCHA is a code executable in the visitor's browser. It is not a static image as used in typical CAPTCHAs.
Having received our CAPTCHA, it's virtually impossible to transfer it to third parties in order to run any task what spammers also do bypassing typical CAPTCHAs.
Probability of guessing the answer by submitting a random solution is 1 to 30,000,000.
KeyCAPTCHA-used images are transferred encryptedly.
Compatibility
KeyCAPTCHA supports two operating modes: Flash and HTML5. The KeyCAPTCHA HTML5 mode is used in most modern browsers, such as Mozilla FireFox, Google Chrome, Safari, and also used in iPhone and iPad. The Flash mode has been developed to be used in Internet Explorer and Opera. While loading, KeyCAPTCHA identifies its operating mode depending on the visitor's browser.
KeyCAPTCHA Affiliate Program
KeyCAPTCHA Affiliate Program allows publishers as well as any Internet user to collect incomes. For more information on The KeyCAPTCHA Affiliate Program, go to Our CAPTCHA Blog.
Automated spam registrations drop to zero with KeyCAPTCHA installed. It appears to be the most effective captcha solution developed. I recommend it over the others.
Their support team is also generous. After I migrated to a difficult server, they helped me install, no fee.
So far this has been working great for my site. Running Glowhost as well and havnt even had any show for that. Only issue is I just noticed that IE was having problems but support is currently working with me on it.

We have checked KeyCAPTCHA on the same IE and the same Flash. Everything looks fine. We sent you the following:
Try to open "Internet options->Security". Click "Default level" button in the "Security level for this zone" section. And click "Apply" button. After that try to check KeyCAPTCHA again.
My website is VERY international and I get people from all over the world, many who dont speak english. Not only does this CAPTCHA stop spam perfectly it is also universal so anyone of any language and keyboard configuration can do it.
can't get it to work in 4.1.9 was working great but now when you click on Human Verification manager in VBulletin settings there is no selection to let you select Keycaptcha in the list..just the default ones that come with VBulletin.
