Authentication and Access Control Agent Framework for Context-Aware Services

A key challenge in a ubiquitous network society is the design of effective authentication and access control schemes that adequately meet the unique security issues posed by the context-aware service paradigm. Despite recent advances in Web services security approaches, issues remain that impede the development of context-aware authentication and access control framework for the ubiquitous computing environment. In this paper, we propose a distributed system based on authentication and access control agents characterized by autonomic policy decision, network federation and dynamic access control for context-aware services. We will describe the travel navigation service system implementation as one of the context-aware services and also report unresolved issues, which include network mobility support, trust relationship among agents and device interconnection.

Integration of collaborative and systematic approaches for service design

This paper discusses how collaborative and systematic approaches can be integrated for service business planning. We have surveyed several business startups in our company and concluded that service startup can be considered as a sequence of measures to reduce the uncertainty of the most important issue. In addition, it has been concluded that collaboration between the service provider and service users can reduce those uncertainties. Assuming that business planners will adopt this conclusion as the guiding policy for their planning, we propose a business planning procedure using both collaborative and systematic approaches.
