The Many Faces of Identity
summary
Explains different aspects of digital identity by breaking the problem into separate challenges: naming (how things get names), discovery/knowledge (how others learn the correct name), and authentication/proof (how an entity proves it is that name). Uses this partitioning to analyze existing identity technologies and point out areas where current deployments could be improved.
