Password based schemes has been the standard means of authentication over decades. Enhancements use entities like ownership (something one possess), knowledge (something one knows), and inherence (something one is) as first factor and mobile phones as token less second factor, in combinations, to offer different levels of security assurances, trading off usability. In this paper we present ‘2CA...

In open source projects, usability aspects cannot be improved unless there are ways to test and measure them. Hence, the increasing popularity of open source projects among novice and non-technical users necessitates a usability evaluation me...

There are many existing models of usability and instruments to measure it, such as the Administrative Scenario Questionnaire (ASQ) and the Satisfaction Usability Scale (SUS), and the Network Satisfaction Scale (NET). Performance metrics also exist to measure efficiency and effectiveness. However, none of these instruments have been used, separately or together, to measure the overall usability ...
