Notice Controller Credential builds on the Kantara ANCR, Consent Receipt Record format, to provide a digital controller credential,


In privacy regulations and for decentralized identity, transparency is a key requirement. As identifiers are personal, used to track, surveil and profile its not only important to know who controls  personal information, but it's required for consent, a critical component of security and a pre-requisite for digital privacy.  Most notices, notifications, T&C's don't use standards to provide the transparency over who control's personal information.

Specification Overview 

This specification builds upon the Kantara ANCR Record specification (and Consent Reciept)(ref) to build a notice controller credential for specifying all of the PII Controller's information in a eNotice record. 


ISO/IEC 29184 - Online Privacy Notice and Consent Controls  - 

Fields Added to ANCR Record to Create Verifiable Credential

ANCR Record spec - is here (enter link)


  1. Controller Type[Ctype]:  
    1. Notice Controller,  
    2. PII notice controller,  
    3. PII controller,    
    4. PII surveillance controller , (info not provided by PII Principle) 
    5. [Ctype] controller operator, 
  2. Accountable Person Type


ANCR Record provides a PII Controller Digital privacy transparency KPI, be assessing a notice for digital and physical controller identification and privacy access information, as required for the operational use and management of digital identifiers. 

The Controller Credential assessment tests this credential for its transparency performance. 

Security Considerations

The use of blinding identity taxonomy for personal identifiers includes the Accountable person identifiers, which are required to be published and available in accordance to local legislation. 

The identifiers used in the controller credential are specified according to regulation and implemented with standards in order to be subject to regulation and regulatory considerations, 

Mitigation Risk

Using standard framework for transparency of control with data control defaults

Information technology — Security techniques — Privacy framework

ISO/IEC 29100:2011 provides a privacy framework which

  • specifies a common privacy terminology;
  • defines the actors and their roles in processing personally identifiable information (PII);
  • describes privacy safeguarding considerations; and
  • provides references to known privacy principles for information technology.

W3C DPV  0.01Data Privacy Vocabulary
  • legal ontology for technically breaking down and mapping legal ontology to a data legal ontology - 
  • the Notice +  CR V1.2 and W3C DPV, also use a common set of purpose categories. and the Kantara CR v1.1 for purpose specification
