Abstract: This paper surveys the state of the art in authentication, authorisation, and auditing for ubiquitous computing. The survey covers a range of recent work, of which 12 representative contributions are compared side by side along 20 criteria. The paper also describes a vision of invisible security that integrates unobtrusive multi-factor authentication with probabilistic models that take into account social relationships and natural behaviours, such as borrowing credentials as a form of access delegation. This vision recasts current probabilistic models for authentication and argues that the traditional separation of concerns between authentication and authorisation needs to be revisited.

Keywords: access control; authentication; ubiquitous computing; context awareness; authorisation; invisible security; probabilistic modelling; social relationships; natural behaviours; access delegation; auditing.
