For more than a decade, ontologies have been proposed as a means to enable sharing and reuse of knowledge. While originally relatively narrow information landscapes have been in mi...
We present rendezvous-based access control for access control in the pre-hospital environment. Rendezvous-based access control is a simple cryptographic access control method that...
Access to distributed databases containing tuples collected about mobile physical objects requires information about the objects’ trajectories. Existing access control models ca...
In this paper, we present a solution to the problem of dynamically deploying grid service factories onto computing nodes running an implementation of the Open Grid Services Infras...
In this paper, we describe a local safety knowledge sharing system among the community. Our system makes it possible to share detailed safety knowledge, which includes location an...
