I-Card Provider
Contents
Overview
- An I-Card Provider is responsible for instantiating and managing I-Card instances (that implement the I-Card Interfaces)
- A Provider is also responsible for importing I-Cards from serialized data formats. For example a CardSpace I-Card Provider would be responsible for being able to import CardSpace format data files.
- A Provider must somehow configure themselves with resources that may be needed by their I-Cards. For example, a CardSpace I-Card Provider must know the endpoint for the local Token Issuer (STS).
- Different I-Card Provider implementations use different protocols for retreiving identity information. Some might use WS-Trust to request a Digital Identity from a local STS (for self-issued cards), others from a remote STS (managed cards). Still others provide RSS feeds to identity information stored in the Identity Attribute Service
- The Higgins project is developing these types of I-Card Providers:
- Cardspace-compatible
- RSS-P
- SSFF (ScreenScrapeFormFill)
- planned: OpenID-H-compatible Managed
- ...others
CardSpace-compatible I-Card Provider
- This provider will support interoperability with CardSpace relying parties and CardSpace/WS-Trust compatible IdPs.
- It will support both managed and self-issued CardSpace-compatible I-Cards
- It will be able to import CardSpace-format managed cards
Self-issued and Managed Cards
- Are single Digital Subject I-Cards
- The I-Cards implements the I-Card and TokenIssuerCard I-Card Interfaces:
- The TokenIssuerCard impl code manages the metadata necessary to request a Digital Identity token from a local or remote STS
Self-Issued Cards
- The self-issued card instances will implement the IdASCard interface (see I-Card Interfaces)
- The TokenIssuerCard impl code will leverage a local STS that can create Idemix compatible-tokens (in addition to the usual CardSpace-compatible token types)
- The IdASCard impl code manages manages the metadata necessary to retreive claims that are provided to the local STS Token Issuer
RSS-P I-Card Provider
- This provider "projects" a Digital Identity to an external site as an RSS+SSE feed. The relying site may optionally also be able to provide a feed in the reverse direction to allow the relying site to update the identity information
- RSS-P I-Card Providers implment the I-Card, URLIssuerCard, and IdASCard interfaces
SSFF Provider
- Implements the I-Card, IdASCard, and SSFFCard I-Card Interfaces
- The IdASCard implementation code uses IdAS to manage the identity data that is being synchronized (via HTML scraping and form filling)
- The SSFFCard implementation code returns to HBX the script necessary to perform screen scraping and form filling on the target site
