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.

I just was getting ready to set this up on my forum until I noticed this part:

3. Go to the "vBulletin Options" - "Human Verification Manager" page and switch radio-button to Disabled. Click "Save" button.

Does this mean I can not use this in conjunction with the built in vbulletin checks?

I want to use this but not if it means turning off all other forms of verification, I do not trust ANY of them alone, I want to use multiple methods.

Hi, biggazillakilla,
we are analyzing statistics from 800+ websites using our KeyCAPTCHAs. If we see that any our particular captcha exhibits an abnormal low rate of correct solutions or increased time in its passing, we remove it from the pool of captchas.

We are constantly working to simplify them. So, already after this thread start we:

• released jigsaw puzzle-type KeyCAPTCHAs
• added thumbnail of an image sample to be restored

Thanks, again, you for drawing our attention to this issue.

We missed it because we concentrated on the desi5257's number 1 rule of web design that captchas' tasks should have been clear without (reading) an explanation

Hi, Hornstar,
thanks for helping us.
We've changed the title of this post (increasing its anti-spam context) and plan to announce it in forums of VBulletin of other versions.

Meanwhile, please note that you can download and install KeyCAPTCHA plugin for VBulleting 4.x (as well as for 3.7-3.8.5 versions) directly from our site https://www.keycaptcha.com/?changelang=en . It is free but you should register to find instructions because they are specific per each of many different supported CMSs .

Thanks again for your help and interest,
KeyCAPTCHA Team

Yes, you understood it correctly.
We do not have plans to change it in the nearest releases.

but on other side it is great work to prevent the spamers as well as users too....

Hi, Nazia,
no need to hire anybody. Our KeyCAPTURE is free with free support.
Recently, we released a new type, (jigsaw) puzzle, that, as we believe, is much simpler. Everybody played it in childhood

One may try it online on our www.keycaptcha.com site

It is supposed to be intuitive and passable without any instructions

Hi. Thank You For Sharing this Interesting Mod.

The Add-on doesn't work on Internet Explorer 6.

It don't Display the Image Verification.

Many Persons in the World Still Use Internet Explorer 6 and Windows XP, is Important that the Add-on Works on them.

It'd also be Nice the Support of other Languages like Spanish.

It'd also is Important to have the Option NOT to Replace the Image CAPTCHA System but to Work Appart from it. It'd be Nice to have the Option to have BOTH Systems Working on the Boards.

My Best Regards.

Hi, inciarco,

Internet Explorer and Opera, all versions, should have Shockwave Flash

KeyCAPTCHA requires "Shockwave Flash Object" plugin installed in all versions of Internet Explore and Opera.
In all other supported browsers and mobile devices KeyCAPTCHA uses HTML5

If Flash is disabled or not installed then a visitor will see on KeyCAPTCHA in a browser the text telling that it requires Adobe Flash 9.0.115 or higher to be installed.

We re-tested KeyCAPTCHA on IE6+Windows XP.

If this message is not shown then it is possible that a website visitor has, for example, Ad Blocker plugin for blocking Flash.

[s]We plan to start supporting Spanish in our KeyCAPTCHAs in a month.[/s]
Upd: Spanish is currently supported

[s]At this moment we do not have plans of adding such option but we are contemplating on reconsidering our priorities.[/s]
Upd: We tested and could not reproduce this problem. Plz open support ticket to look into your issue specifically

Best,

Hornstar, wow,
We seemed to initially miss this your third already helpful to us hint to understand why there are so many requests for having more than one protection (in earlier posts by inciarco and by Kestryll

After some googling we found that many articles on internet advise to install second protection as the (only?) way to stop the spam surge due recent reCAPTCHA (used by vBulletin forums) cracking on 4th of January 2011.

We should stress that reCAPTCHA cracking was quite obvious and expectable, due to may reasons, suffices to say that Google Inc., owning the reCAPTCHA, does not use it by its own services, for ex., Gmail registration, etc. Some obvious weaknesses of reCAPTCHA were already explained on internet before.

Though, KeyCAPTCHA is conceptually different service having multiple levels of novel mechanisms of protection and it was never cracked yet.

KeyCAPTCHA anti-spam service is unique in that it is platform specifically developed to overcome many drawbacks of other (previous) anti-spam services. For example, in contrast to other captchas, KeyCAPTCHA allows to easily and fast change the type of employed captcha without the need to re-install its plugin in protected webservers of our old customers, in case it is broken.

Does Keycaptha have a ToS ?

Maybe integrate this with spam-o-matic to provide multi-layered protection?
