Abstract:
JSON Proof Token (JPT) is a compact, URL-safe, privacy-preserving
representation of claims to be transferred between three parties.
The claims in a JPT are encoded as base64url-encoded JSON objects
that are used as the payloads of a JSON Web Proof (JWP) structure,
enabling them to be digitally signed and selectively disclosed. JPTs
also support reusability and unlinkability when using Zero-Knowledge
Proofs (ZKPs).
A CBOR-based representation of JPTs is also defined, called a CBOR
Proof Token (CPT). It has the same properties as JPTs, but uses the
JSON Web Proof (JWP) CBOR Serialization, rather than the JSON-based
JWP Compact Serialization.
