  • Anti-spam revenue generation through advertising;
  • Social advertising protected against spam;

  • Instead of asking visitors to guess symbols, our CAPTCHA gives a simple interactive job.
  • If KeyCAPTCHA hasn't been correctly solved, page refreshing won't happen, preventing the user from filling out the form more than once. It happens because a form's CAPTCHAs are initially checked in the KeyCAPTCHA servers before being sent to the secure web server.

  • To create a digital signature, a password with a variable length of 112 to 165 bits is employed.
  • The visitor's browser is where the code for KeyCAPTCHA is executed. It is not a static image like those found in standard CAPTCHAs.
  • When someone receives our CAPTCHA, it is practically hard to transfer it to a third party so they may perform any operation, like spammers can do when they get around standard CAPTCHAs.
  • A random solution has a one in 30,000,000 chance of correctly predicting the solution.
  • Images used by KeyCAPTCHA are sent through encrypted channels.
