Towards a context aware modeling of trust and access control based on the user behavior and capabilities

During the last decade, several context based security models has been proposed to take into account the user behavior aspect. However the studied context is mainly related to device and spatio-temporal features, which may led to a weak and inappropriate contextual modeling. By using the huge and various contextual data issued from the sensors deployed in smart environments, our objective is to provide a security framework suitable for dependant people. This paper shows our approach to model both trust and access control based on the deduced user behavior and capabilities.
