Authentication Using Session Based Passwords

Abstract

A very severe issue in today's computing world is the ‘ACCESS’ to an authenticated user. The most common and popularauthentication mechanism is to use alphanumerical usernames and passwords including special characters and digits. But, textual passwords are most of the time prone to dictionary attacks, shoulder surfing, etc. Hence, graphical passwords have been introducedin this paper as an alternative to authentication schemes. Though the graphical password schemes help in generating more userfriendly passwords, they are still vulnerable to shoulder surfing. To address this issue, text along with images can be combined togenerate more secured passwords. Session passwords, as the name suggests can only be entered once and then, a new password isgenerated for the next session; thereby making the authentication process much stronger.
