Revision as of 23:20, 8 December 2006

This page describes the one mandatory I-Card interface that all types of Higgins-compatible I-Cards must implement, as well as these optional interfaces:

  • TokenCard
  • URICard

Base ICard Interface

All I-Cards must implement the ICard Interface:

// Return the human friendly name of the card
String getDisplayName();

// Set the human friendly name of the card
void setDisplayName(String);

// Return true if this card only manages information about a
// exactly one Digital Subject
boolean isSingle();
 
// Returns if 'isSingle()' is true, an optional contextually-unique identifier for the Digital Subject
// Otherwise return null.
String getCUID();

// A card identifier that is unique to the card issuer. Or at least that
// is what we believe the semantics that Microsoft intended and we currently
// see no reason not to follow
// Return the identifier   
String getCardID();

// Returns the human friendly name of the card issuer, originator, creator
String getIssuerName();

// Sets the card's human friendly name of the card issuer, originator, creator
void setIssuerName(String name);

// Returns a background image of the card
Image getCardImage();
 
// Sets the background image of the card
void setCardImage(Image image);

// Return the mime type of the background image (JPEG or GIF)
String getImageMimeType();

// Returns when the card was first issued, created, orginated
Date getTimeIssued();

// Returns (optionally) the time after which the card should
// be considered expired, invalid. Otherwise returns null
Date getExpiredTime();

// Set the expiration date and time
void setExpiredTime(Date date);

// Return the date and time after which the card should be 
// treated as expired and invalid. If there is no expiration 
// If card handles only simple claim types then 
// return a list of all possible types of claims that are supported
// throw exception otherwise
// This is here for backward compatibility with CardSpace cards
List getSupportedSimpleClaimTypes();

// If card handles complex claim/attribute types then
// return a data structure containing nested lists of claim types and 
// string values (this needs work!)
TBD getSupportedComplexClaimSchema();

// Retrieve the value of a simple claim type
// Note: Implementations of this method will likely retrieve and cache all 
// supported simple claim type values in a single operation 
// Returns the value of the claim type ClaimType
String getClaimValue(String ClaimType);

// TBD: how to retrieve the value of complex claim types

// Given a relying party policy Policy, return true
// if this card can provide the claims required/desired by the relying party
// else return false
// Note: we have discussed the need (esp for Idemix support) to indicate the
// degree of match, not just a boolean.
boolean isMatch(Policy);

// Return whether the user wishes to be asked for explicit release of
// this card's information (i) every time it is requested (ii) only 
// the first time it is requested (iii) never 
ReleasePolicy getReleasePolicy();

// Set the release policy of this card
void setReleasePolicy(ReleasePolicy);

// Return a list of the types of expored card data stream formats supported
// ?? presumably a CardFormat also mentions XML language and/or version number
List getSupportedExportFormats();

// Return a data stream containing a serialization of the card
// The format depends on the kind of card 
// E.g. CardSpace I-Cards will export CardSpace format data
String export(CardFormat format);

To Do

  • Need methods to get/set the access control list idea (see I-Card)

TokenCard Interface

Some types of I-Cards may implement this interface.

// If card is of type (1) then return a Digital Identity 
// that satisfies the policy policy
// The credential parameter used to authenticate to the 
// Token Issuer–-may be null if Token Issuer policy doesn’t require it
DigitalIdentity requestDigitalIdentity(Policy policy, DigitalIdentity credential);

// Return the EPR of the card issuer
// For CardSpace cards this is either the local STS endpoint (for
// self-asserted cards) or a remote STS (for managed cards)
EndpointReference getCardIssuerEndpoint();

// Return a list of {endpoint references, credential hint, credential selector}
List getTokenServices()

// Return a list of supported token types
List getSupportedTokenTypes(); 

// Is the RP identity required in the token request message?
boolean getRequireAppliesTo()

// Returns the issuer that is referenced in the returned RSTR (or null if no issuer is listed)
String getIssuedTokenIssuer();

URICard Interface

Some types of I-Cards may implement this interface. The card object encapsulates a ContextRef URI (that may be an XRI) that refers to an identity attribute-providing service (usually a network endpoint).

The I-Card Providers developed as part of the Higgins project use the Identity Attribute Service to connect to the remote (or local) Context data referenced by this ContextRef

(Note: If ICard.isSingle() is true, then implementations can invoke ICard.getCUID() to retreive the CUID of the Digital Subject with the Context returned by .getContextRef() below.)

// Return a URI --the ContextRef 
String getContextRef();
