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.

Two things for me render this product unusable for my site:

1. Failed registrations provide no visible feedback to the user.

If a registration fails, only if the KeyCAPTCHA puzzle is solved does the system alert the user of why the registration failed.

Under the default human verification system of vbulletin, the system immediately alerts the user of why a registration failed (mismatch password, invalid email address, incorrect CAPTCHA, etc.)

The 'registration' button is at the bottom of the registration page. When the user scrolls to the bottom to click the button, the KeyCAPTCHA image is no longer in view. The only alert KeyCAPTCHA provides for an incorrect puzzle solution is the display of a red crossed out circle. This red crossed out circle is not in view because the user has scrolled to the bottom of the page. So, the registration fails, and with no visible feedback provided, the user is left clueless as to why the page does nothing. The user can of course scroll back up, but the red crossed out circle displays for a couple of seconds and then disappears, most likely before a user scrolls back up. Eventually a new user would figure this out, as did I, but I would rather not frustrate new users that try to register - they might leave.

This would definetly work to stop spam bots, but also to frustrate new users.

2. The KeyCAPTCHA can be blocked by a firewall

I visited my site from behind a firewall and the KeyCAPTCHA image was not visible because it was blocked by the firewall. This means that other users that are behind firewalls may be precluded from joining my online community.

Despite the above two issues, I believe that this is a good product. It just doesn't suit my needs.

Hi, Rock Anthony,
thanks for your time and feedback.

In the most nearest time we shall add an alert warning a user when the captcha was solved incorrectly

Firewall can block any service or website, it is its purpose.
If someone uses a firewall, (s)he should configure what (s)he wants from it
(to block or not)

Thanks again for your time and valuable feedback!

[Rock Anthony]

Well, thank you for hearing me! I'm extremely gratefull that you've considered my feedback enough to implement changes in the next release. Thanks!

Thanks again for your time and valuable feedback!

What port should I tell my users to open so that KeyCAPTCHA will function?

There are cases where a person is behind someone else's firewall, and has no authority to configure that firewall (computer lab on a university campus, for example). For situations like that, it would be nice for service providers, such as KeyCAPTCHA, to use well-known ports that are not commonly blocked by firewalls. (Perhaps KeyCAPTCHA is using a well-known port, and the firewall I'm behind is blocking anyway.)

vBulletin is obviously served through well-known ports. I have no problems accessing any part of my vBulletin message board behind the various firewalls I'm protected by. I want the same for my users - including those firewalled users that would like to register, but are precluded from doing so because KeyCAPTCHA is blocked via firewall.

Consider that the default vBulletin registration page renders on the screen, with a message to assemble the KeyCAPTCHA puzzle - but there is no puzzle image displayed on the screen because it's been firewalled. There's not even a image placeholder to give hint to the user that an image should be visible, but isn't. The user took the time to complete the registration page, but is stuck and clueless because (s)he is instructed to complete a puzzle that is not there.

Despite what's stated above, so far I'm impressed enough with KeyCAPTCHA that I'm trying to talk myself into overlooking this firewall issue. Perhaps I can just put a notice on the registration form that firewalled users may or may not be able to register.

Hello, Rock Anthony,

Why have you decided that it is firewall of your users that block KeyCAPTCHA images?

KeyCAPTCHA protects thousands websites and we hear such complaint (indicating firewall, as the reason of a problem) for the first time.
There can be various reasons (like browser plugins for blocking ads, some specific configurations of your network/webserver/browsers. incorrectly installed/configured plugin, etc.)

Please open support ticket from under logged in user on our keycaptcha.com site with detailed description permitting to reproduce your problem and/or communicate with you context-sensitively and/or resolve the issue directly on your site

I had decided that the firewall is the source of my problem (and could be a problem for my users) because I only experience this issue when accessing my site from behind the firewall of a particular private network.

However, I owe you an apology. I sincerely apologize for making the assumption that the firewall is the source of my problem. You know your product infinitely better than I do, so shame on me for diagnosing the problem when I'm not qualified to do so.

I've opened support tickets on your site, and can attest that you've been nothing but useful and helpful. And you have a wonderful product that fulfills a great need.

I followed the link that you provided. I will revisit that private network that I mentioned and check the browser settings. If I'm unable to remedy the problem, I'll open a ticket on your support site.

Please accept my apology.

Sincerely,
Rock Anthony

Rock Anthony,
you are welcome!
We'll be happy to help anyone.

I used to get around 20 spam bots registering on the site, now it is basically zero.

KHALIK,
we appreciate your feedback in forum just now because we liked to have it as last post.

We appreciated it through PM much earlier, so it is not a lack of consideration.

I Share The Following Tips to KeyCAPTCHA Users to Stop and Control SPAMMERS, TROLLS and LEECHERS, From Registering in Your vBulletin Boards, I Like to Post it on All the KEYCAPTCHA Mod Topics because I Know this Will Benefit All vBulletin Board Administrators:

Is 100% Impossible to STOP SPAMMERS (Persons) From Registering, (NO SYSTEM CAN Simply Because Humans Find Ways to Try and Joke Any Registration System), but You Can Implemment and Configure Other Systems to Reduce That From Happening:

1. KEYCAPTCHA (Stops 100% of SPAM BOTS), So USE IT.

2. Create and Set "User Profile Fields", and Force Users to Write Answers in Them, so that They Have to Write Coherent Answers, (SPAMMERS, TROLLS, and LEECHERS Will Provide Wrong Answers and those You'll BAN For doing that because those are SPAMMERS).

3. Use the "COPPA Registration System", so that No Person Can Write ANY Birth Date, and Also to NOT Accept Registrations Under 13 Years Old.

4. Set To YES the "Moderate New Members" Option on the "User Registration Options", so that You Can Review the Answers that Users Make to the "User Profile Fields" Before Accepting their Accounts. Give Yourself the Opportunity to BAN TROLLS and SPAMMERS that Write TRASH on those Fields, they for Sure Will Be SPAMMERS.

5. Set "Follow Forum Moderation Rules If no, posts are always placed into moderation queue" on "Post / Thread Permissions" as "NO", for Usergroups Not Approved ("Not Activated" and "Pending Approval"), so that Every message They Post is Moderated, and that Way NO SPAM from HUMAN SPAMMERS or TROLLS is Viewed (can be Posted but NO ONE WILL SEE IT), and that way if they Post SPAM You BAN THEM and Delete their TRASH Posts. NEVER Allow those Usergroups to Create New Threads.

6. Use Also an Additional System as "vMail - Verify Mail before registration", so that No User Can Register Without Validating His/Her Contact E-mail Address.

7. Use Also another Additional System as "NoSpam! for vBulletin 3.7", so that Users Have to Answer a Validation Question (like a Mathematical Question or whatever related to Your Web Site), so that No User Can Register Without Knowing the Answer to that Question.

8. There are other thing More to Tell, but with the Previous Ones You'll STOP SPAMMERS, TROLLS, and LEECHERS, so much, that You'll Reduce their Registrations and Keep Them Under Control. Also Many Users Will be Annoyed by that, but You Have to Choose if You Want QUALITY Users Registering or Just QUANTITY (The Quantity don't Participate, they're Just LEECHERS).

I 100% Recommend KEYCAPTCHA, Because is a Beautiful AntiSPAM-BOT System, and Also Provides a PUZZLE System that Only Humans Can Solve.

Thank You Very Much KEYCAPTCHA. :up::up::up:

My Best Regards.

inciarco!
thanks for your time and support

I answered to Morrus in the thread where he had reported the issue.

Still we believe that additional measures are helpful in extreme cases of attack
but usually the correct engagement of KeyCAPTCHA leads
- to less administrative maintenance,
- less complexities in installing/maintaining permitting to refuse from multiple (multi-layered) plugins installation/configuration
- to increase user-friendliness (we have multiple reports when users switch off moderation upon starting to use KeyCAPTCHA)
