The main objective of this paper is to report on a pilot test for a proposed formal model for e-Healthcare readiness assessment. The model provides a tool for determining critical factors of e-Healthcare readiness such as need-change readiness, engagement readiness, structural readiness and, acceptance and use readiness. These factors constitute the main constructs of the model which are formalized...
Many e-health portal systems are implemented using off-the-shelf software components. The security features provided by such components are usually insufficient. This paper addresses the issue from the access control perspective. More specifically, we first propose a two-tier approach to access control for e-health portals. The approach supplements existing role based access control (RBAC) capabilities...
Petri nets are a well-known paradigm for simulating dynamic systems. Coloured Petri nets are characterised by tokens with attributes whose values are changed by events in the model. They cannot play an active role in the system behaviour. Using them to model human beings, with continuously changing attributes and simple decision-making abilities, would require a large number of auxiliary elements...
In applications such as e-Health systems, a user's consent should usually be obtained before his/her private information can be disclosed. For this purpose, users need to specify their privacy preferences about what data are to be disclosed to which recipients for what purposes. However, this may become a daunting task in a complicated application that involves potentially a large number of combinations...
