Abstract: In this paper, we describe a policy-based access control implementation for Task Computing using the Rei policy engine. Task Computing lets ordinary end-users accomplish complex tasks on the fly from an open, dynamic, and distributed “universe of network-accessible resources” in ubiquitous computing environments as well as those on the Internet. The Rei policy specification language is an expressive and extensible language based on Semantic Web technologies. The Rei policy engine reasons over Rei policies in OWL and domain knowledge to answer queries about the current permissions and obligations of an entity. To provide unobtrusive and flexible access control for Task Computing, a framework was created in which several Rei policy engines were endowed with Web Services APIs to dynamically process facts from clients, the private policies of service providers, shared policies, and common shared ontologies. The framework is implemented and deployed for Fujitsu Laboratories of America (FLA), College Park office and evaluated.

TL;DR: In this article, a semantic service description (SSD) is associated with a service, wherein the SSD comprises a semantic description of the service, including an interface parameter, according to a computer interpretable language, and, as a service grounding, a mapping between the computer-interpretable language expressing the SSD and an interface.

Context-Based Privacy Protection for Location-Based Mobile Services using Pseudonyms
TL;DR: This paper discusses the combination of a nifty pseudonym generation mechanism that is used to veil the real world identity of users with semantic user context descriptions and policy reasoning to express decisions of users and thus protects their sensitive location information.

- 20 Oct 2003
TL;DR: It is argued that "task computing" offers an incentive to device manufacturers to incorporate semantic web technologies into their devices in order to get the benefits of easier and more flexible use of their devices' features by end-users.

TL;DR: The specifications of the Rei policy language are described, which provides constructs based on deontic concepts that are extremely flexible and allow different kinds of policies to be stated.
Ontology-enabled pervasive computing applications
TL;DR: To support task computing, a Task Computing Environment including client environment, service discovery mechanism, and Semantic Web services and tools is implemented including STEER, White Hole, and PIPE.

Modeling conversation policies using permissions and obligations
Lalana Kagal,Tim Finin +1 more
TL;DR: In this paper, the authors propose a declarative representation of conversation specifications and policies in terms of permitted and obligated speech acts, which can help in agent communication in three ways: (i) to filter inappropriate messages, (ii) to help an agent to decide which speech act to use next, and (iii) to prevent an agent from sending inappropriate messages.

TL;DR: This work presents an architecture and a proof of concept implementation of a security infrastructure for mobile devices in an infrastructure based pervasive environment using "Rei", a lightweight and extensible language which is able to express comprehensive policies using domain specific information.
