Kantara Initiative - Advanced Notice & Consent Receipt - ANCR-WG Charter


(1) WG NAME (and any acronym or abbreviation of the name):  

Advanced Notice and Consent Receipt Work Group


The ANCR WG will address the technical gaps, and take advantage of recent legal and standards development, to update version 1.1 of the Consent Receipt Specification.

Context: V1.1 was published on 20 February 2018 before GDPR was enacted. V1.1 was included in ISO 29184 Online Privacy Notices and Consent (released on 6 June 2020) as Appendix B where it is defined as a Consent Receipt Notice.

(3) SCOPE: 

  1. Publish a Notice and Consent Receipt Specification to address the technical gaps in the current specification and include recent standards and other technical and legal developments.
    1. Update the initial consent receipt specification by specifying the explicit consent record fields for legal proof(s) of notice and proof of consent.
    2. In the update take advantage of ISO 29184 and other relevant technical standards, laws and policy developments.
    3. Address technical gaps in the initial consent receipt specification, with new specifications, e.g.  a data privacy vocabulary.
    4. Innovate in accordance with Kantara Operating Procedures and promote a consent notice receipt (a receipt that is a notice of consent) as an international tool for human, legal and decentralized identity governance and interoperability.

(4) DRAFT TECHNICAL SPECIFICATIONS: List Working Titles of draft Technical Specifications to be produced (if any), projected completion dates, and the Standards Setting Organization(s) to which they will be submitted upon approval by the Membership.

Software developers, and product managers as a means of achieving interoperability across a wide range identity, security, and privacy of use cases. Developers of decentralized governance and next generation internet services.

Regulators looking for technical controls to implement legal requirements.

For human beings, as the implementation of the notice and consent receipts provides an alternative/complement to terms and of services and privacy policies to provide something that can be understood by people. This is in contrast to the “biggest lie on the Internet”, namely that privacy policies and terms of service address privacy concerns and provide safeguards of personal information.

Operators of identity, privacy, security, and consent systems in the real world.
