The work so far What have been done so far – Completion of Study Phase – Completion of Social Model Development Completion of Social Model Development – Completion of the System Design

Future targets Implementation – Developing a secure Event Heap – Developing applications so that we can test the new secure Event Heap Testing our system Evaluation of the system Writing the final technical report Completion of the final deliverables

User perspective Who interacting with and when Where the users and items Which services they can provide and I can get

Summary Joint project between KTH and Stanford University A new and very interesting area There are differences between “classic” security and ubiquitous computing security Lesson learnt
