Aim: To propose a system for convenience in using CAPTCHA by the Visually Impaired person.Method: To make this access secure CAPTCHA (“Completely Automated Public Turing test to tell Computers and Humans Apart”) was invented. This form of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen. This traditional method receives many criticism from the disable people. Hence a finger print based CAPTCHA is introduced.Result: A CAPTCHA MONSTER, a convenient system of breaking CAPTCHA for the Visually Impaired is Proposed.Conclusion: Thus in this proposed system, it is possible to access the web services on websites for various day to day applications by effective authentication procedure.
