“Geometric and Math CAPTCHA”
by Suttikeat Meelap, Nuttanont Hongwarittorrn in the Proceedings of CIT and UniNOMS, March 2013


This research presented a geometric CAPTCHA which was not created from images in any database, but it is an image of a geometric shape that randomly generated from a program and its edge was incomplete. Geometric CAPTCHAs were tested with users to identify the number of angles from a shape and to do a simple calculation. Users must type a right answer to pass the CAPTCHA test. Geometric CAPTCHAs were test run with other similar three CAPTCHAs in terms of time for task completion, number of errors, and user's satisfaction. This paper was a pilot study for designing a new image- based CAPTCHA, and the improved design will be made in the short future.
