Collaborative approach to secure agents in ubiquitous healthcare systems

Abstract

In sensitive domain such as healthcare, lives of people are controlled and it is very important to have fast access to health information especially in case of emergency (e.g., chronic diseases). For that, agent paradigm is very promising in ubiquitous healthcare systems. But, the inherent complexity of information security is bigger because agents are characterised by autonomy, intelligence and not under the control of a single entity. Indeed, the big challenge in agent-based ubiquitous healthcare systems is to assure that emergency workers and doctors can access personal information fast and whenever needed but with high level security. The idea, in this paper, is to lighten agents with simple cryptography concepts while strengthening the surveillance and make it collaborative. Consequently, all agents of the system are concerned by security and collaborate to maintain it. The proposed agents are implemented in JADE-LEAP platform designed for restricted devices.
