A JSON-Based Identity Protocol Suite

Achieving interoperable digital identity systems requires agreement on data representations and protocols among the participants. While there are several suites of successful interoperable identity data representations and protocols, including Kerberos,1 X.509,2 SAML 2.0,3 WS-*,4, 5, 6 and OpenID 2.0,7 they have used data representations that have limited or no support in browsers, mobile devices, and modern Web development environments, such as ASN.1,8 XML,9 or custom data representations.
