Kantara Initiative Advance Notice and Consent Receipt WG late stage draft.ToIP – DDG: Controller Credential Specification
Version 0.7.1
July 4, 2022
Abstract
This is specification builds upon the Anchored Notice and Consent Receipt (ANCR) Record Specification and its schema to specify a controller credential. Building upon the operational privacy an transparency of the ANCR record to provide a KPI for assessing the performance of the operational privacy and its associated PII Controller security.
This is accomplished by specifying a regulated controller credential from international (non-national) standards and requirements that are reflected in laws and regulations. The Controller Credentia can then be it's holder to specify and negotiate the delegation of authority of data control and governance amongst all privacy stakeholders. This establishes the basis for standardized digital identifier governance utilising evidence of Consent to decentralized the control of personal data and it's processing.
The ANCR Record Semantic Schema Stack:

Introduction

Digital Identity Security

Document

To Address a critical security flaw native to digital identity technology, where people are a) identified before the authority to generate an identifier or process personal data has been granted b) are unable to see which PII Controllers are processing personal data and when they are processing it after it is collected.
Critical Security Flaw – notice to digital identity technology is the lack of notice or standardized transparency over who is control, prior to authentication, lack of mutual agreements on authorization,

The 3 goals of this specification are to;

Scalability

Overlay Capture Architecture

a. OCA is used to map and overlay the field name and label of the corresponding legal privacy elements, and to assess conformance of the credential information against standards, laws, and codes of conduct and codes of practice
iii.Regulated Credential Mapping
1. any stakeholder can create a controller credential, making it ideal to provide as a public utility for transparency conformance with regulation for health, safety, data disclosure, sharing, monitoring, and as permission transport vehicle in the form of a token.
a. a controller credential can be used to generate micro-credentials by signing concentric notice receipts that are generated from an ANCR Notice Record.

Security Considerations

The 0PN Decentralized Data Governance framework employs a Data Control Impact Assessment (DCIA) in order to make transparent the control and trust vectors for a specific system and service.
The Controller Credential is embedded into notices, notifications and disclosures to address self-soverign transparency requirements for decentralized data governance. This embeds the missing security for personal data control in a notice or notification.
This provides the transparency discovery mechanism for the individual to provide the authority to generate and processes a decentralized identifier.
In this way, this specification will address native security flaw in native to digital identity management systems which in effect governance of this alpha surveillance technology.
Achieving Objective 1 of this specification for a ToiP standard.
More information, The credential, and use of DiD's for verifiable credentialling is addressed in the 0PN Decentralized Data Governance – trustworthy Identity system architecture. (ref)
credential with lack of standard transparency over Authority, e.g. who a person is consenting too and what
The DCIA – provides this standardized transparency over the scope of authority and the providence of the decentralized Identifier, in order to :
1. a) create and manage digital identifier
2. b) to process and permission personal information
iii.the controller credential provides a public credential for people to more easily and use for its intended purpose, which is transparency over who is accountable
iv.the person acting on behalf of the company, as well as the accountable person safeguarding the company are roles that are regulated, providing a regulatory framework and tools set for the governance of SSI

  1. Blinding Identity Taxonomy is used to blind the PII Principals identifiers

ToiP Governance Interoperability

Mapping Governance
Key is mapping the authoritative and international standards to the ToiP gov model.
Semantics
First are the semantics, table of the different terms that are used then mapped to the ToiP framework,
Second, is the DCIA
Third is the stakeholder roles from DDG to the functional roles in the ToiP stack, e.g. holder, verifier etc. These provide governance authorities with an overarching framework for the privacy and identity assurance programs.

Governance Semantics


i.the international privacy frameworks which are represented with a privacy controller credential provide a human centric definition for some terms which differ from ToiP's, functional identifier centric glossary,
a. Identity,
b. Permission
c. Governance
d. Trust
e. DGA Registry: culture and privacy regulations are rich with these standard terms and definitions which have evolved since the 1980 Transborder flows of personal data, from best practice, to standard, to regulation, and with CoE 108 +, an international framework for robust data governance.

conformance assessment of ToiP framework


When reviewing an SSI system, First define the service point and context of identifier use. In this context identify which SSI stakeholder is the PII Controller.
1. Is it the verifier, the issuer or the holder?
2. Factors of Authority & Delegation
1. First Factor Policy: Apply legal governance rules according to the location of the PII Principle
2. Second Factor Policy: Apply contract governance rules
3. Terms
a. First Factor Policy (regulatory)
PII Principle Policy – interacting with a public (relevant to all stakeholders)
Big G – Gov – for physical and public space.
1. implementing law with codes of conduct which are used to extend regulation for a specific sector, industry, context. Reviewed and approved by a regulator.
b. Second Factor Policy (co-regulatory)
i.Parental Consent, Terms and Conditions, by laws, representing local, context specific or regional policy
c. Third Factor Policy i.ToiP Stack
d. Fourth Factor
