Improved Authentication scheme using password enabled Persuasive Cued Click Points

In Today's world Authentication plays a vital role. Traditionally text based passwords are used for authentication which have several drawbacks. The study shows that graphical pictures could be used for authentication which have various advantages over text based password. Shoulder surfing and hotspot are the two main issues in Graphical passwords. Sonia Chiasson et. al. proposed the method of a persuasive cued click-point which reduces the hotspot problem, but provides no security mechanism for shoulder surfing attack [1]. In order to address these issues, the proposed work enhances the persuasive cued click point based method with a major change, having a additional invisible password input for each points. Moreover concept of fingerprinting is used to ensure that the system is securely used by users.
