CAPTCHA (Completely Automated Turing Test To Tell Computers and Humans Apart) were initially created to protect Web Forms against Robots and spammers. But by now, CAPTCHA has become a problem itself.
CAPTCHAs are difficult and annoying for standard users, very difficult for old people and almost impossible for people with disabilities. Also, CAPTCHAs are very difficult for everybody on smart-phones.
With CAPTCHA you can see your site conversion and retention go down.
While CAPTCHAs are hard for human users, they are easily understood by spambots that use advance OCR tools to read CAPTCHAs and send spam easily in the Web forms. So, Web sites have to use more and more complicated CAPTCHAs, and human users cannot read them. That's why CAPTCHA does not resolve the spam problem and make your users go away.
Keypic helps you get rid of Spam, and of CAPTCHA
Keypic doesn't require any action from the user. Keypic system analyses users' behaviour and automatically separates humans from bots and spammers.
Prevent Comment Spam in Blogs and forums
Most bloggers are familiar with programs that submit bogus comments, usually for the purpose of raising search engine ranks of some website (e.g., "buy penny stocks here").
This is called comment spam.
With Keypic, only humans can post comments on a blog, and bot actions are really restricted.
There is no need to make users sign up before they enter a comment, and no legitimate comments are ever lost!
Protect Website Registration
Several companies (Google, Yahoo!, Microsoft, etc.) offer free email services.
Most of these services suffer from a specific type of attack: "bots" that would sign up for thousands of email accounts every minute.
The solution to this problem is to use Keypic Web Service as it ensures that only humans obtain free accounts.
Free services should be protected with Keypic in order to prevent abuse by automated programs.
Prevent Dictionary Attacks
Keypic also prevents dictionary attacks in password systems.
The idea is simple: we prevent a computer from being able to iterate through the entire space of passwords by blocking access after a certain number of unsuccessful logins.
Secure Online Polls
Keypic can protect your polls from bots that try to vote with their common Bots techniques.
Yes, Keypic provides online advertising services by substituting a CAPTCHA with an ad banner but the keypic banner is hidden now with css.
Get your Keypic, and stay protected from Spam without CAPTCHA!
