Dynamic Authentication over Graphical Passwords using Visual Cryptography
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2015, Vol 4, Issue 10
Abstract
CAPTCHA is a test build by computer programs which human can pass but computer programs cannot pass CAPTCHA as graphical passwords (CaRP) are a graphical password scheme used for a user access authentication. It is mainly used for a security purpose to avoid the spyware attacks from website. Using this CaRP to protect the attacks from spyware access a new model to take the new experienced image spaces trouble in well graphical password taken such as different Points which is extends to insufficient password selections. Captcha is provide security , but it take s sensible security and usability and comes out to fit well with some practical lotions for different online security Captcha as graphical passwords is mixed the numbers strings and a graphical password model We take different reviewing authentication model Two Factor Authentication (2FA) is devices such as tokens and ATM cards is taken number of short comings is associated with resent passwords but they include the cost of purchasing, issuing, and managing the Tokens or cards.
