Driver's licenses are used to claim that we are capable of operating a motor vehicle, university degrees can be used to claim our education status, and government-issued passports enable holders to travel between countries. This specification provides a standard way to express these sorts of claims on the Web in a way that is cryptographically secure, privacy respecting, and automatically verifiable.

A verifiable claim is a qualification, achievement, quality, or piece of information about an entity's background such as a name, government ID, payment provider, home address, or university degree. Such a claim describes a quality or qualities, property or properties of an entity which establish its existence and uniqueness. The use cases outlined here are provided in order to make progress toward possible future standardization and interoperability of both low and high-stakes claims with the goals of storing, transmitting, and receiving digitally verifiable proof of attributes such as qualifications and achievements. The use cases in this document focus on concrete scenarios that the technology defined by the group should address.

This specification defines how to secure Verifiable Credentials with JSON Object Signing and Encryption (JOSE) especially as explified by JSON Web Signatures (JWS) [RFC7515] and with CBOR Object Signing and Encryption (COSE) [RFC8152]. This enables the Verifiable Credential data model [VC-DATA-MODEL]to be implemented with standards for signing and encryption that are widely adopted.

Credentials are a part of our daily lives; driver's licenses are used to assert that we are capable of operating a motor vehicle, university degrees can be used to assert our level of education, and government-issued passports enable us to travel between countries. This specification provides a mechanism to express these sorts of credentials on the Web in a way that is cryptographically secure, privacy respecting, and machine-verifiable.

Among other things, the [VC-DATA-MODEL] specifies the models used for Verifiable Credentials, Verifiable Presentations, and explains the relationships between three parties: issuers, holders, and verifiers. Critical pieces of functionality referenced throughout the [VC-DATA-MODEL] are the that of of verifiability, extensibility, and semantic interoperability. This specification provides a mechanism to make use of a Credential Schema in Verifiable Credential, leveraging the existing Data Schemas concept.
