Abstract

Ubiquitous computing systems collect and share a great deal of information upon the users and their environment; including private or highly sensitive personal information. Unless users are confident enough that their privacy is protected, many will be deterred from using such systems. This paper proposes a privacy type system that controls the behaviour of concurrent, context-aware and mobile processes to ensure that private information is not accidentally disclosed. We prove the subject reduction property and the soundness of the proposed type system; which guarantee that a well-typed process cannot accidentally disclose private information. We demonstrate the pragmatics of our approach with a case study.
