ANCR Working Group

ANCR Working Group — Kantara Initiative

The Anchored Notice and Consent Receipt (ANCR) Working Group builds inspectable, implementation-ready artefacts for notice and consent receipt exchange. Our flagship artefact is the Consent Receipt, and its evolution into the ISO/IEC TS 27560 Notice Receipt Extension.

The Consent Receipt

The Consent Receipt is Kantara’s foundational transparency artefact: a machine-readable record, handed to a person at the point of notice, that captures who is processing their data, for what purpose, under what legal basis, and how to exercise their rights. It turns consent from an unverifiable claim into inspectable evidence.

Lineage:

1. Kantara Consent Receipt — the original specification that established the receipt as the unit of consent evidence.
2. ISO/IEC 29184:2020 (Annex B) — the Consent Receipt was adopted into ISO as the hosted consent-receipt / consent-record reference, explicitly citing the Kantara Consent Receipt specification.
3. ISO/IEC TS 27560:2023 — became the international consent record information structure.
4. ANCR (Anchored Notice and Consent Receipt) — anchors the receipt to a verifiable controller identity and a notice event, so the record is not just issued but traceable.
5. Notice Receipt Extension (now complete) — extends ISO/IEC TS 27560:2023 into a receipt-exchange profile for anchored, inspectable notice evidence.

Where to find the spec:

• ISO/IEC 27560 ANCR Profile Extension package (versioned): 27560 ANCR Profile Extension
• Current working entry point: ISO-27560 TS Extension
• Archived baselines: v1.01 and v1.02 under the same package.

Submission index (PWI 26689)

The following working-group outputs correspond to the documents submitted for ISO/IEC JTC 1/SC 27/WG 5 (PWI 26689 — Notice and Consent Records):

• 27560 Notice Receipt Extension — the receipt-exchange profile extending ISO/IEC TS 27560:2023 (the N-doc that carries the Consent Receipt into the standard).
• PWI 26689 Gap Analysis, Part 1 (Scope A) — the cross-reference of ISO/IEC TS 27560:2023 against the receipt-exchange requirements.
• WG5 / CoE Liaison materials — the plenary and Council of Europe liaison decks. WG5 Report 03-2026 materials

Note: the canonical version for the submission is a working-group decision and is not yet fixed in this repository. See the package index for details.
