Identity Management: Strengthening One-Time Password Authentication through Usability

Usability in HCI (Human-Computer Interaction) is normally understood as the simplicity and clarity with which the interaction with a computer program or a web site is designed. Identity management systems need to provide adequate usability and should have a simple and intuitive interface. The system should not only be designed to satisfy service provider requirements but it has to consider user...

Enhanced User Graphical Password Authentication with an Usability and Memorability

Authentication is the process to provide guaranteed information security and the graphical password authentication method is a convenient and easy process to provide authentication. The major problem of user registration, mostly text base password, is well known. If the login user be inclined to select a simple password which is frequently in his mind it becomes straightforward for attackers to...

On the Usability and Security of Graphical Password Schemes

In recent years, graphical passwords have been proposed as an alternative to traditional alphanumeric passwords, which demonstrate weakness in necessitating exact recall and thereby promoting the selection of insecure passwords. Because there is much evidence to suggest that humans have a greater capacity to recall images as compared to text, graphical passwords hold promise as a form of authen...

Authentication Using Graphical password: Effects of Increased Security on Usability

Graphical User Authentication (GUA) is a method that uses images as passwords, instead of alphanumeric characters. We propose PassDecoy, a shoulder surfing resilient GUA system, and through previous research has been shown to have a higher degree of security when compared to PassPoints (Chaisson et al. [3]). However, previous work has exposed a password problem, where the effect of increased se...
