Verifiable Claims


Verifiable Claims is a Claim that can be verified.

Verifiable Claims when verified is then a Verified Claim

Verifiable Claims typically refers to the (W3C) Working Group focusing on standardizing a number of signed claims or assertions regarding a person, entity or thing.

Verifiable Claims has a close relationship to the Verifiable Credentials Working Groups' work although the relationship is not well defined.

Verifiable Claims is an Architecture and not a specific Design or Implementation

Verifiable Claims is a draft specification proposes a data model for claims about entities having to do with identity profiles. A claim in the Verifiable Claims system has these elements:

The proposed charter states: “It is currently difficult to express banking account information, education qualifications, healthcare data, and other sorts of machine-readable personal information that has been verified by a 3rd party on the Web.”

The specification discusses self-sovereignty briefly but does not provide a solution for this element at this time. The Verifiable Claims architecture document calls for a registry of globally unique identifiers but the specification does not provide a solution for this element at this time.

There is discussion ongoing in the Verifiable Claims community about a formal role for Linked Data.

A "Verifiable Claims" is a trusted assertion an issuer makes about an subject to an Inspector-verifier who is authorized to request such n. More specifically, it is machine-readable statement made by an entity that is Cryptographically authentic (non-Repudiation). A "credential" (aka attestation) is defined to be a set of Verifiable Claimss that refer to a qualification, achievement, personal quality, aspect of an subject such as a name, Government Identity, preferred Payment Processor, home address, or university degree typically used to indicate suitability. The VCWG was established on the notion that there is currently no widely used User-centric standard for expressing and transacting Verifiable Claims via the Web. As such the aspects to be standardized by the VCWG are the set of Verifiable Claims that consists of the Subject Identifier, the Claims (about the subject), and the Claims Set Metadata. All claims are digitally signed by its issuer. The architecture of the proposed Verifiable Claims ecosystem follows that of the classic “four-corners” model used in the Payment Card industry.
