Designing for trust

Information systems exist in every aspect of our life. Therefore we need to make sure that users trust these systems in order to continue to use them. However, developing a trustworthy system is a challenging task for the right operation of the system as well as system's acceptance from the users' perspective. Ensuring well-placed trust always depends on the trustworthiness of the trustee, i.e. the system. Therefore, properties that belong to the trustworthiness highly influence to the development of trust. Nevertheless, trust has to be considered from a holistic perspective, since it covers a wide range of issues that belong to different disciplines. In this paper, we present the relevant properties of trust and trustworthiness from a holistic perspective and we define trustworthiness as the competence and ability of a system.
