New Graphical Password Scheme Containing Questions-Background-Pattern and Implementation

Abstract

Security of authentication is needed to be provided superlatively to secure users' personal and exchange information, since online information exchange systems have been developed according to internet speed. Therefore, aim of the chapter is to develop current graphical password scheme based on recall, create and implement a new graphical password scheme composed of three layer verification. We programmed our scheme in order to use in section of anonymous information exchange system and user's registration of trading chat room. While we conducted survey on user by accessing participant to our system lied in participants' local network and we analyzed in accordance with the average length of their created password and statistical significant of entropy bit. From the survey of total participants, our scheme has statistical significance, furthermore it was proved that it can secure form a variety of attacks as entropy bit was high.

A Hybrid Graphical User Authentication Scheme in Mobile Cloud Computing Environments

“…Afterward, the authentication server shows images as a challenge in the authentication process and users must pick the correct im a ge to answer the given question. A graphical recall-based authentication scheme in [13] involves triple verification layers. The authors improved the security of PassGo scheme by adding secret questions, responses, and background images.…”
