"Identity & context for a changing world"

Published:13 November 2009Publication History

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
