Experimental project
This is a sandbox project, which contains experimental code for developer use only.
PICATCHA™ is a unique image-identification CAPTCHA that effectively protects your website from Internet abuse - spam and automated bots. It is a well known fact that websites loose approximately 3-18% of user interactions (comments, sign-up etc) due to the additional burden of re-typing the squiggly garbled text CAPTCHAs. Imagine if your website is being visited from a tablet device or a smartphone - the end user is left to zoom/pan, decipher the text and typing with auto-correction makes the whole experience frustrating. It is also inevitable that mobile Internet will eclipse desktop Internet, and we believe that as a website administrator you make the right CAPTCHA choice and be ready for this shift.
Hence, PICATCHA™ was designed keeping all these factors in mind - to give the highest levels of user experience to your website visitors while ensuring the strongest defense against spam on all kinds of devices. PICATCHA™ presents the website visitor with an array of thumbnails. The visitor clicks and selects them to verify that he/she is a human interacting with your website and not an automated bot. PICATCHA™ changes the standard CAPTCHA test of "are you a human?" from a necessary evil to a positive experience.
PICATCHA™ is a FREE web service developed initially at UC Berkeley, USA by a team of students and professors with research focus in user-interface design, web security and system design. You may enable it to stop spam on sign-up forms, registration pages, comments, polls and many more. We developed plugins for all versions of Drupal - 5x, 6x, 7x for your convenience.
