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.

Well had this installed on 2 of my Forums and it worked Great but I have a 3rd Forum now and when I install the product and configure it as per instructions I do not see it in the list of options to use. I am using vBulletin 4.1.12 Patch Level 1. I see the options to set up but not the option to use this product.
Warning: fsockopen() [function.fsockopen]: unable to connect to back7.keycaptcha.com:80 (Connection timed out) in [path]/includes/class_humanverify_keycaptcha.php on line 52
now if its installed and I only want it in the registration process is that possible I dont want members having to use it every time they make a thread.
Warning: fsockopen() [function.fsockopen]: unable to connect to back7.keycaptcha.com:80 (Connection timed out) in [path]/includes/class_humanverify_keycaptcha.php on line 52
Any fix to the class_humanverify_keycaptcha.php ?

The only issue I found was wondering where the human verification manager was.
I thought it was in options "human verification options" and couldn't see the radio button.
After a bit of googling I spotted it was "human verification manager" and this is separate to the options list. Just click "Settings" and you'll see the "human verification manager" just above social bookmarking.
Anyway... thanks again! Very good, useful and enjoyable plugin!
i installed it and you can tell right away what a relief it is going to be for the new members to signed up, thanks great system, it seems regular captcha was just getting to much , I cant read it almost 80 percent of the time, refresh refresh uggggg : ( but i have to give credit to them also hard to keep up woth the bots

my internet explorer version: 9.0.8112.16421 version of update: 9.0.9
