eKYC & IDA Working Group - Charter
The eKYC and Identity Assurance (eKYC & IDA) WG is developing extensions to OpenID Connect that will standardise the communication of assured identity information, i.e. verified claims and information about how the verification was done and how the respective claims are maintained.

eKYC & IDA Working Group Charter
1) Working Group name
eKYC and Identity Assurance Working Group
2) Purpose
Maintain OpenID Foundation specifications for providing Relying Parties with identity information, i.e. verified Claims, along with an explicit attestation of the verification status of those Claims (what, how, when, according to what rules, using what evidence). These specifications are aimed at enabling use cases requiring strong identity assurance, for example, to comply with potential regulatory requirements such as Anti-Money Laundering laws or access to health data, risk mitigation, or fraud prevention.
Build upon OpenID Foundation specifications for providing Relying Parties with identity information with particular focus on:
- Attachment of binary elements (needed for conveying identity evidence in some use cases)
- Representation of when a subject has authority to act for another entity such as person authorised to act for a legal entity or person authorised to act for another person
- Extension to enable RPs to request that the return data be data minimised in specific ways
Terminology
[SOURCE: ISO/IEC 24760-1:2011, 3.1.2, modified – entity has been replaced by subject, added mapping of attribute to claim]
identity information verification
process of checking identity information and credentials against issuers, data sources, or other internal or external resources with respect to authenticity, validity, correctness, and binding to the entity
verification
process of checking information by comparing the provided information with previously corroborated information
verifier
actor that corroborates identity information
person
human being
subject
person whose identity is being proofed
identity
set of attributes related to a subject
identifying attribute
attribute that contributes to uniquely identifying a subject within a context
Note: in the context of OpenID Connect represented as a “Claim”.
supporting attribute
attribute that is used in identity proofing but not as an identifying attribute
identity information
set of values of attributes optionally with any associated metadata in an identity
evidence of identity (EOI)
evidence that provides a degree of confidence that a subject is represented by the identity being claimed
authoritative evidence
holds identifying attribute(s) that are managed by an authoritative party
Note: A point in time copy of the identifying attribute(s) is liable to become out of date and therefore becomes corroborative evidence.
Note: This is one type of evidence of identity.
authoritative party
entity that has the right to create and responsibility to own and directly manage an identifying attribute
Note: Law sometimes nominates a party as authoritative. It is possible that such a party is subject to legal controls.
corroborative evidence
holds identifying attribute(s) that are not managed by an authoritative party
Note: The identifying attributes in corroborative evidence may not be as up-to-date or accurate as authoritative evidence.
Note: This is one type of evidence of identity.
proofing information
information collected for identity proofing
proofing party
party that performs identity proofing of a subject
Authority (or authority to act)
From Britannica Dictionary “the power or right to direct or control someone or something” Note: the “someone” for the purposes of this specification is a “natural person”, and the “something” is a “legal entity”. That power or right will often clarify any ambiguity around the scope or purpose of the action allowed.
3) Scope
- Maintenance of OpenID for Identity Assurance Specifications
- Development of profiles of the OpenID for Identity Assurance with work on a mechanism for registering re-usable values at key parts of the Identity Assurance metadata
- A mechanism to represent, request and provide claims about the authority a natural person may have to act for another natural or legal person
- Development of a specification that enables attachment of binary objects into an identity assurance payload
- Extension to the request – response capabilities of OIDC to allow for more granular data minimisation
- Not making breaking changes to existing OpenID Connect specifications
Out of Scope:
Legal or regulatory advice, Identity Proofing, identity information verification
4) Proposed specifications
OpenID Attachments 1.0
OpenID for Authority 1.0
OpenID Connect Advanced Syntax for Claims 1.0
5) Anticipated audience or users
- Identity Verifiers
- Application Developers (acting as RPs)
- Age assurance providers
- Ecosystem architects and designers
- Identity Providers (IDPs) or Claims Providers
- Trust Framework operators
6) Language
English.
7) Method of work
Mailing list and telephone/internet conference calls combined with F2F (where needed) and
information sharing/collaborative working via online tools.
8) Basis for determining when the work is completed
WG consensus based on implementation experience. The work will be completed once it is apparent that maximal consensus on the drafts have been achieved, consistent with the purpose and scope.
