ABSTRACT
This talk presents how an Identity Enabled, Policy Based, Context Aware - Composition of Federated Content and Services will be the basis for addressing service delivery in a "Changing World". Context STARTS with a User (and his/her identity) and a sub-context;
Task or Enterprise Context (user's activity/activities as an employee, doctor, citizen, etc.)
Social Context (friends, family, mentor, coach, redskin fan, etc.)
Personal (physical and mental attributes about a user)
Spatial-Temporal or Mobility Context (attributes such as time, location, movement, calendar, etc.)
Environmental Context (users surrounding - including entities, such as others, devices, etc.)
Therefore an Extensible and Flexible Identity System, can handle any type of a "Construct of Credentials for a Given Context as the Identity of an Individual for a given use case", support several hundred mechanisms associated with Authentication, support various mechanisms of Access Control and Authorization (including ABAC), support multiple Service types -- including multi-media (regardless of the underlying technology - .Net, JEE, etc.), multiple content types, document types and more. Beyond AuthN Context and AuthZ/Security Context, other Intelligence about the User (Attributes) is critical to address contextual delivery of service -- since the context is ever changing (including: Identity & Authentication Assurance Levels, Reputation Ratings, Attribute Aggregation and Analysis, Risk Ratings, Trust Attributes, and more). This Keynote is based on the 3rd book in the series on Identity - "Identity & Context", published in 2009

Context-based matching for Web service composition
In this paper, we propose a novel matching framework for Web service composition. The framework combines the concepts of Web service, context, and ontology. We adopt a broad definition of context for Web services, encompassing all information needed for ...
A context type model for context-aware discovery of web services
ACST'07: Proceedings of the third conference on IASTED International Conference: Advances in Computer Science and TechnologyA service registry such as UDDI is an important component for service discovery in an open Web services environment. Service discovery is refined if the registry is context-aware, i.e. realising the contexts of the querying service consumers as well as ...
Towards a context-based multi-type policy approach for Web services composition
The objective of this research work is to look into the role of policies and context in framing the composition of Web services. Context supports the development of adaptable Web services and policies specify the behavior of Web services engaged in ...
