Notice & Consent Task Force

Notice & Consent for people relies on clear communication. 

Decentralized identity relies on contextual legal semantics and notices by implementors in order to be compliant with sovereign data rights.  These semantics need to be standardized to be used by decentralized identifier based technologies for human interoperable data governance.  

The more unified across ecosystems the notice and risk semantics, the more human centric the service becomes as it lowers the burden on humans and increases the understanding of risks, benefits and (human) consent.

Specification proposal:  to extend Decentralized Semantic Governance for a dynamic data control ( DDC) architecture for active control transparency that people can use.

 Privacy Privacy Controller Receipt Credential (Control Provenance Credential) 


  1. The accountable person may or may not be an employee of the organization. 
  2. Different jurisdictions name/define and reference this role differently 
  3. Some jurisdictions, like the UK have a data controller registry, where this binding is public and legally required (benefit in this case, challenge where absent)
  4. Some jurisdictions, like the EU require an accountable data controller representative in the jurisdiction where a service is operating, in order to address legal data privacy and security issues that may arise. 
  5. 2 or more Controllers might be accountable for processing of personal data.
  6. Identify in context of service for any user the controller and accountable person.
  7. The privacy law in some jurisdictions, can itself break privacy law in other jurisdictions by requiring the accountable person information to be published publicly, 
  8. Specifies how to by a VC (in this case the Privacy Controller Credential) for trust assurance for privacy assurance
  9. International Notice & Control protocol for  Unified Data Control & Portable semantics for governance interoperability between domain and jurisdictions.


 specification requirements

Develop this controller credential specification with a set of rules for the use, maintenance, and lifecycle of a privacy controller credential, that is independent of the privacy controller. 


  • a record format that MUST blind the identity of the accountable person,
  • be usable as a linked data in a notice of control receipt, which provides only the controller information required for the purpose of credential use. 
  • record, so as to provide a profile of the bound controller credentials in a manner that can show the controlling person before, during and after the use of a decentralized digital identifier.
  • control providence begins with the person making the assertion to the accountable role using laws and standards to bind privacy rights request to a legal entity  



Supporting Decentralized Data Controls with Identity Governance for Data subject’s (data) rights. This task force mission is to enhance identity and data governance interoperability  with standardized notice of Control and accountability for processing personal data (with the  ToiP layered governance model.)


This specification will provide a nested schema to record a privacy controller credential for transparency over the control of processing.  This privacy controller credential is intended to use a stack of standards and specifications to provide a standard set of identity control semantics, that can then be used in notice and notification by people to control personal data directly to provide Privacy assurance. 

Background of this Stack

  1. A key challenge to interoperability is addressed with the International ISO/IEC standards framework 29100 and 29184. This provides a semantic control framework to address the lack of semantic harmonization for personal data control  which provides security for the portability and control of private information and is a required for people to be able to independently consent and control personal information.  This challenge first presented the W3C DoNotTrack Conference in Berkeley California. 'Opening Up the Online Infrastructure
  2.  This turned into a Kantara Specification effort in 2014 and now, last year, ISO voted to fast track this to a standard 27560, to be used with ISO 29184 to address what was know by the  phrased of the Biggest Lie on the Internet, was a focus of a movie Terms and Condition's May Apply. With an international governance rule set, people can use independently of Terms and Conditions. 
  3. With the success of this work as an international standard this Task Force aims to collaborate to support an International data governance authority framework as an open resource for master identity control transparency over personal information (with standardized notification for the PII Principle)

Decentralized Semantic Governance Stack

The Identity and Data Governance semantic based line is the international ISO/IEC 29100 security and privacy techniques framework, this is mapped to Legal jurisdiction notice schema and the differnces and risks (in terms of rights and the performance of data controls) is provided as a component of the notice of control.
