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.

Looks like a very clever idea. I like that the adverts are optional.

I wonder how accessible it is though? i.e. for partially sighted or physically disabled users.

I personally use text CAPTCHAs such as a simple arithmetic question for accessibility reasons.

We are planning to develop a version of KeyCAPTCHA for disabled persons.
But at the time there are only what you see.

Really good to know, thank you!
And please don't think I was being negative about your module, it really does look very interesting.

That's ok )

For anyone trying to implement this now, it seems that KeyCaptcha no longer send verification emails out in order to get a private key, making this obsolete. Unfortunately reCaptcha no longer works either. Does anyone know of any other solution?

Hi!
Could you tell me your email to activate your account?
* you can send it to support@keycaptcha.com
Sorry for inconvenience(

For anyone in a similar position as me, using phorum, under spam attack, and looking for an alternative to the deprecated V1 reCaptcha, KeyCaptcha isn't a solution. I used it in tandem with the GIF spam hurdles, and have had massive spam attacks from bots that made it through both KeyCaptcha and javascript GIF captcha.

Use the StopForumSpam module.
