Securing Text & Image Password Using the Combinations of Persuasive Cued Click Points with Improved Advanced Encryption Standard

Abstract

Security is the main aspect for any application. The main aim is to protect the system from the illegitimate users. The online library system is considered for study and two way authentication techniques are applied on it. Two way authentication techniques are used to protect the data by using both the text and graphical passwords. Graphical password scheme is used named as persuasive cued click points (PCCP). On both the text as well as graphical password, Improved Advanced Encryption Standard (IAES) algorithm is applied to provide better security. It means system provides two step authentications with the encryption technique. In IAES, one random generated key called as SALT is added with AES key. By adding the Salt key with AES the number of combinations of attack will increase. Even if the database is compromised then also attacker cannot gain the actual text password and click points of the graphical password. Three (3) click points are provided for the user, after clicking on first area the image get expanded for the next click and so on till the third click points. Dictionary attack is removed totally.
