Web Services

The Liberty Alliance Project has defined a framework that supports the development of identity-based, identity-consuming, and standard web services, in addition to clients of such services. This framework, which was first released publicly in 2003 and has continued to be enhanced, has been successfully implemented by many organizations. We continue to do work developing and further refining the fundamental architecture. Given its open, standards-based approach, it also lends itself well to other organizations developing services to complete more specific tasks. Our services group is focused on defining and developing such services, and has successfully completed a lot of work. Additionally, we have a public special interest group, the Web Services Harmonization SIG, working to harmonize Liberty's identity web services work with other web services specifications in the industry.

Case Studies

This presentation showcases a working implementation of provisioning secure credentials to consumers, using Liberty Alliance protocols and specifications. It is based on a proof-of-concept project between Intel, HP and BT. Their converged service proposal offers three main benefits: improved user experience, network agnostic access with universal coverage, and support for extended range of multi-mode user devices. The use case is explored in-depth in this presentation.

This piece details the Intel Identity Capable Platform, which was demoed.

The Intel Identity Capable Platform, based on Liberty's ID-WSF, is a trusted environment
which offers full lifecycle support for Manageable Identities, that can provision, update, delete, activate, deactivate, and aerialize/deserialize. Offering complete portability, it is capable of over the wire/air as well as physical provisioning with policy-controlled access and operations. This presentation details this project and its use of the Liberty standards.

A case study involving a mashup of Google Earth and fboweb flight tracking information stars in this presentation, which dissects the functionality at hand and the solution that Liberty's ID-WSF standard delivers in meeting the needs of: 1) SSO at the service level (as opposed to browser session level); 2) an identity model to identify parties in transations; 3) an identity model that supports chained transactions; 4) an interaction model that supports backend interactions; 5) a discovery model that allows per-user discovery; and 6) a token management model that allows context translation.

Liberty 2.0 Creating ID-WSF Services - John Kemp
Presented by John Kemp of Nokia
This hands-on presentation provides code and an approach for creating services for Liberty's ID-WSF Framework.

With the rapid adoption of SOA, there is an equally prominent pain point around the ability to protect the architecture as a whole. Many of the solutions currently being deployed are focused on protecting web services. However, this addresses only part of the architecture…it does not address the need to enforce policies around non-web services, the ESB, etc., and doesn’t even begin to address the proactive opportunity of enabling single sign on across the architecture in a heterogenous environment or acknowledge the roll identity has to play in the overall solution.

This webcast focuses on this business challenge, introducing a possible solution based on injecting identity into the SOA architecture through all its layers to enforce policy and enable SSO. It looks at standards such as SAML 2.0, ID-WSF, WS-Trust and WS-Security, and how they are leveraged in this solution (all you Concordia followers….this webcast is a must!). It also examines how a Security Token Service (STS) is used in this solution to enable security and translation of tokens in a heterogenous environment where we have both standards based and proprietary implementations. This webcast explores the future of federated authorization where developers can leverage XACML and SAML 2.0 as well as commerical applications that are identity aware and pluggable into and existing identity infrastructure.

This presentation reviewed current projects and activities underway in OpenLiberty.org, with an emphasis on the ID-WSF 2.0 Client Library with a sample code overview, and the FireFox ECP Plugin. Future activities are also discussed.

The ability to easily develop identity services to sit on top of Liberty's Identity Web Services Framework is largely appealing to developers. In this presentation, Sampo reviews the technology that makes this possible and some of the services that have already been created, including Contact Book, Content Services Messaging (aka ID-Messaging), Identity based Directory Access Protocol with extensible data schema, Personal Profile, Employee Profile, and GeoLocation.
