Abstract

Even though trust is a frequently articulated topic in software technology literatures, yet the user centered point of view of trust is hardly discussed. How users perceive the trustworthiness of software systems is not trivial, in fact, if a user cannot trust a program to execute on his behalf, then he should not run it [36]. This paper identifies a potential lack in examination of trust in software systems from user's perspective and aims to develop a conceptual User-Centered-Trust (UCT) framework to model it. This model integrates both Technology Acceptance Model (TAM) and trust under Theory of Reasoned Action (TRA) nomological network. In order to integrate them, trust has been conceptualized as an attitude towards the usage of the systems having two distinct dimensions: cognitive and affective.
