"Higgins is an open source Internet identity framework designed to integrate identity, profile, and social relationship information across multiple sites, applications, and devices.

"The heart of the Higgins user experience is the i-card - a visual metaphor for a set of digital identity data about you, someone you know, or a website you use."
