Overview

Provides support for Higgins clients, including the Higgins Browser Extension.

Token-based Authentication

• Get a Digital Identity

// Get a DigitalIdentity that will satisfy the RP agent's policy
// Return a DigitalIdentity token
DigitalIdentity getDigitalIdentity(RPSPolicy policy)

Example use: When the user's browser with the Higgins extension lands on a site that requires a Digital Identity for authentication, HBX sends a 'getDigitalIdentity' request to RP Protocol Support passing the Relying Party Security Policy along as a parameter.

Implementation: RP Protocol Support simply returns the result from the I-Card Selector Service's 'getDigitalIdentity(RPSPolicy policy)' method.

Connection to Higgins Client

• Create a new account on the Higgins service registered to the client (e.g. HBX)
• Verification of HBX authentication
• Returns the Terms of Service of the Higgins service (human readable text document)

HTML form filling

getFormFillingScript

If there is a form filling script for the web page currently open in the browser, retreive data from the appropriate I-Card, and pass this data along with the script the client (e.g. HBX) so that the client can fill in forms on that page

/**
 * Gets a form filling script for the specified site&user
 * @param page the browser's current URL
 * @param username the user name
 * @param form the HTML form name
 * @return a form filling script
 */
public String getFormFillingScript(String page, String username, String form) 
  throws java.rmi.RemoteException;

HTML scraping

getHtmlScrapingScript

If there is an HTML scraping script for the current page&site, pass it to client (e.g. HBX) and retreive from client attribute data that RP Protocol Support can store in a site-specific IdASCard I-Card

/**
 * Gets an HTML scraping script for the specified page
 * @param page the URL of page to scrape
 * @return an HTML scraping script
 */
public String getHtmlScrapingScript(String page) throws java.rmi.RemoteException;

RSS+SSE Support

• Acquire a card

// acquire the RSS feed from the RP site and then 
// create a new (site-specific) I-Card whose attributes are defined in the feed
acquireICard(String subscribeURL)

• Create an RSS-SSE feed that publishes the minimal subset of attributes required/supported by the RP site from the appropriate I-Card. If available, subscribe to a reverse RSS-SSE feed and use the data to update the a site-specific Card I-Card.

OpenID 2.0 Support

• <to be written>

Sign-on Confirmation Notify

// Locate the URIICard-type I-Card whose URI matches 'cref'. If no such 
// card exists, create it. Find the Digital Subject whose unique identifier 
// is 'cuid'. On the uniqueIdentifier attribute value itself: 
// (1) if 'success' is true, add/update to "now" the
//   the lastVerifiedFromSource metadata property's timestamp and
// (2) add/update the lastVerifiedAttempt metadata property's timestamp
//   to "now".
void connectionNotify(ContextRef cref, String cuid, boolean success)

• The Higgins browser extension invokes this method after it has attempted to use the username 'cuid' at the website 'cref' with the password (retrieved from the browser's password manager) along with a HTML scraping script retrieved from RP Protocol Support to sign in to this site.
