A Novel Security Scheme against Spyware using Sequence Selection of CAPTCHA as Graphical Password

our proposed work will be founded on Click-based graphical secret word plans require a client to tap on an arrangement of focuses on one or more exhibited foundation pictures. With Pass Points, clients make a secret word by clicking five requested focuses anyplace on the given picture. To sign in, clients should accurately rehash the succession of snaps, with every snap falling inside of a satisfactory resilience of the first point. To actualize this angle, alongside a plan changing over the client entered graphical secret key into a cryptographic check key, a "vigorous discretization" plan. It comprised of three covering lattices (imperceptible to the client) used to figure out if the snap purposes of a login endeavor were sufficiently close to the first indicates be acknowledged
