Security is a critical requirement for the e-health system because the patient's sensitive information can be accessed remotely and this makes the entire system vulnerable to malicious attacks. In this paper, we present a novel role-interaction-organization security model and apply it to the e-health system which is modeled as a multi-agent system. The roles in our proposed model do not only determine access rights passively, but also initiate requests to interact dynamically with the agents who meet the security requirements. The interaction and the organization models help to identify the actions and responsibilities that a role can assume in the system within the organization and any dynamic interactions it can partake. A simple case from the e-health system is given to illustrate the application of the model.
