Planning a Member Plenary meeting October 26-ish San Francisco (Friday after IIW)

  • Are there specific cross-group items you'd like to propose to work on?
40 minInteroperable Consent Receipt demo at MyData ConferenceAll

1) Dev team status

Google drive folder for export/import of consent receipts

  • Consentua
    • Still on track - deciding on timing of code change deployment on Monday - some front end work to go after that
  • Ubisecure
    • Still on track
  • OpenConsent
    • Viewer exists, able to read consent receipts, working on the UI
    • Can consume and v1.1 CR
  • Trunomi
    • Still on track - JSON examples early next week
  • clym

2) Sequence diagram and roles status

  • Any questions?
  • No other comments

3) Storyboard status

4) Stage narrative status

  • Starting work on this now

5) Team Issues and showstoppers discussion

  • No issues reported

  • Colin - UK ICO grant funding proposal call is open now - Ubisecure, AdUnity interested in this
    • Colin was on the bidders call earlier this week

      I (Andrew) quickly reviewed the Grant info linked above, and I think there might be a fit.

      The possible research topic and solution might be:
      - purposes categories and examples for one or more industry verticals
      - use of consent receipts to inform data subjects of their ongoing rights
      - surveys of opinions of use of consent as a justification for data processing
      - research into standardization of consent management (including market surveys to document current practices)

      Submission deadline is August 17.

Next meeting

2018-08-02 same time, same number



From 2018-07-26 call:

    • n/a
  • Consentua
    • Developers have promised CR output Week of August 6-10 - we will be looking for the output in the shared google folder (smile)
  • Ubisecure
    • n/a
  • OpenConsent
    • Viewer has been started - looking to get receipts from others
    • Target is August 15 to be able to display CRs

  • clym
    • n/a
  • Telus
    • Resource and scheduling estimates for creating an external CR for an existing app


  • Q: in the spec, Services is described as a 'business service'. But these days, companies are describing this as a 'category of business purposes'.
    • A: 'Service' is the name and description of the service - an unspecified field - mainly for humans
    • A: 'Purpose category' is to describe the business service purposes
    • A: If there is a Service with the same Purposes and the same Data as anonther Service, then they are indistinguishable.
  • Q: How are we envisioning asking the 'do you consent to this' question?
    • A: The Notice part of the flows have not been worked out yet in this group, deliberately.
  • Q: Have we decided on what format/location/interface will be recommended for the 'exported' CRs?
    • A: Right now, it's files in the Downloads folder (or a user-selected folder) - the 'real' discussion about this will be deferred until after the demo in August.
  • Q: How does COEL spec relate to the IETF secevent RFC?
  • mydata session - Joss
    • OneTrust, Nixu, JLINC, Kantara
    • Andrew asked for 20 minutes for the demo
    • Joss suggests that the Kantara demo goes last then transitions to Q&A for all
    • Q: Are there special provisions needed on the mydata web site to help people interact with the demo?
    • Need to focus the mydata demo presentation to trigger 'delivery' and action instead of 'interest'

From 2018-07-19 call:

    • new internal release v2.2 is available this week
    • some enhancements to Consent Access functions - some export functions
    • created field mapping versus specification - spreadsheet has been available for a few weeks
    • has new spreadsheet with updated JSON file info - has sent to David and Andrew for pre-review
    • has drafted a 'vendor extension' - proposal for new objects to be added to the spec
    • is done
  • Consentua
    • Service is ready to go - just need to create a format for the CR spec - a configuration change, not a code change
    • work planned to start next week - planning session - will have more status on Monday
  • Ubisecure
    • Minimal prototype - no CR in product
    • They will use the CR generator to create a sample app - a bookshop
    • CR will be downloadable
  • OpenConsent
    • underway to create a Viewer plus Viewer API
    • scheduling estimates underway - target is to demo this at the interop demo
  • Trunomi (via Andrew)
    • currently in their 2-week dev sprint - will have code after next week
  • Telus
    • Resource and scheduling estimates for creating an external CR for an existing app

From 2018-07-12 call:

1) Story board discussion - Richard

  • Diagram A: "Get consent receipt"
    • This is the crux of the demo
      • How does the user know they have a CR? 
        • What will a user experience when this happens?
        • Option: make CRs optional to the user (ask them if they want a CR at all)
      • How do they know what to do with at CR?
  • Diagram B: "List Consent Receipts"
    • The location of this diagram is not specific (on purpose)
    • Two parts here:
      • 1) for any given Data Controller, how will they show a list of CR for the user, to that user?
      • 2) open question about consolidate repos for CRs from many data controllers, for the user
      • Use files to store the CRs
      • Use a filename convention (including extension)
      • Use a dedicated folder to hold the downloaded CR files
      • Use a File Manager to get a list of CRs
    • ACTION: Mark: to ask Joss if the receipt storage application is available (from the COEL work)
  • Diagram C: "View a Consent Receipt"
    • Consentua does not currently do this - who does?
    • has a viewer in the product today
      • He will have a sample JSON receipt export available this week
      • At this time, does not want to be a wallet - so no function planned to import general purpose CRs
      • There are too many wallets on the market already
    • OpenConsent is in planning stages of creating a general purpose viewer
      • Current implementation is for 'privacy receipt' which is a subset of a 'consent receipt'
    • Ubisecure
      • Viewer is not planned for this timeframe - they plan to generate CRs for download through the browser
    • Tom Jones has an XSL for diplaying CRs
  • Diagram D: "Move a Consent Receipt"
    • Open question about how to move the receipt from one system to another
      • Export/download/import (browser)
      • Share action (on mobile)
      • Drag-drop (desktop)
      • Email - do we have a MIME-type for Consent Receipts? (Nope, not yet)
      • Q: What about using an API? A: The diagrams are about user interaction patterns, not infrastructure.
  • 3) Timing for initial testing & location of repo

    • ACTION: Andrew to publish the WG's github repo location
    • ACTION: Andrew to create an publish a Google Drive folder for file exchanges (e.g. Exported CR files)
    • is almost ready to start exporting CRs

From 2018-07-12 call:

Andrew walked through the sequence diagram.

  • Richard - the 'Export' consent receipt might be too disruptive to the user - maybe
  • John Krogulski - what data formats? A: It's set out in the specification
  • Mark - should we be using JWT for transfers?
    • A: This might be a complexity that we should incorporate in later interops
    • A: This is a complexity versus future-proofing question... ANDREW to ask the list/implementers
  • ACTION: All to post comments to the wiki page about the sequence diagram, questions, clarifications etc.
  • Storyboard
    • Ready to draft a user story - aiming for delivery on next call
  • Tom - there are prior activities that are not showing on the sequence - the Data Subject has to be identified to the Controller and Platform including any consents
  • Mark - the "initial consent flow" - the sequence is not showing the bootstrapping sequence - the sequence is showing the ongoing interactions
    • ACTION: Andrew to annotate with prerequistes and assumptions of user already being set up
  • Richard
    • ACTION: to document the technical flows of Consentua in the context of the interop demo sequence
  • Sylvester's Action item:

Receipt Reader

 A receipt reader is an application that parses (reads) consent receipts automatically. A reader only handles consent receipts in it's machine readable format  and is a component of some automatic process. 

Receipt Viewer

A receipt viewer is an application that a human uses to interpret the contents of a consent receipt. An application can only be considered a receipt viewer if it presents receipt data in a human readable form.

Receipt Dashboard

A receipt dashboard is an app used by humans to store and manage consent receipts. A user can use their dashboard to perform batch operations on multiple receipts at a time.

 ACTION: All to comment on these starter definitions, on list (note that the text above has already been edited)

From 2018-06-28

  • Discussed Kartik's v1 of the sequence diagram
  • Park: the discussion about 'viewer/reader/dashboard' and the differences in functionality that those terms encompass
  • Has anyone played with the 'sand' demo app? URLs to follow by email
  • First part of the demo:
    • Data Subject interacts with Organization A and as a result, a consent receipt is created and shown to the Data Subject. The consent receipt is stored in a place that is known to the Data Subject.
  • Second part of the demo:
    • Data Subject starts their preferred app which they normally use to view and manage their consent receipts and sees a list of consent receipts that are in the place referenced from the first part of the demo. Data Subject clicks the new consent receipt and the contents are displayed.
  • ACTION: Mark/Sylvester to write functional descriptions of the 'viewer/reader/dashboard' concepts

From 2018-06-21 call:

  • John walked through the draft scenario
  • Mircea: why would the receiving org need to generate a new CR?
    • A: Depends on the interpretation of Article 20 implementation
  • Jim:'s consent feature requires that the data processor notifies the user on downstream sharing
  • Karik: Trunomi allows counterparties to be defined and data sharing rules defined up front. PSD2 scenarios - has 2 consents that are tracked - 3rd party doing payments on behalf and the financial institution
  • ACH: Would it make sense to just do the simplest thing: one data controller mints a CR and a different org displays it.
  • Richard: important to do display and that the back end system is following the CR instructions
  • Jim: has started work to 'export' a CR artifact. The user might be notified of sharing event.
  • John: starting to think that we should disconnect the demo scenario from any specific regulatory requirement - this should stay a technical demo
  • Robert: agrees - show what you received is what was sent - and show multiple receipts that display in the same way
  • ACH: related that people in unconference sessions are capable of imagining potential uses of CRs - we need to show the simplest functions
  • Kartik: conceptually makes sense - questions on the details about how multiple platforms will play
  • Mircea - need to decide on which systems take on what roles in the demo - which ones create CR, which ones consume & display
  • Richard: in principle it is OK - what does it actually look like to a User - the UX and concept of a CR moving from one place to another - there is no metaphor for this yet
  • Oscar: does not have viewer yet - so this would help to have some else's viewer to use
  • Mark: is the CR moved directly by the back end or are the actions done by the User.
  • ACH: has lined up a mobile operator as a issuer of CRs - but they have no viewer - they need the user to use someone else's viewer
  • ACH: need to do a storyboard
  • Robert: the metaphor should probably be the same as physical receipt management - one place to view them
  • ACTION: Richard to sketch a story board for this
  • ACTION: Kartik to ask questions around how consent management platforms - send to email - includes sequence diagram
  • Mircea - is each consent receipt unique? and should it stay at the originator org? then the only thing transfered would be the CR id?
  • ACTION: Jim - to list some of the high level activities that is undertaking
  • Mark: OpenConsent is planning to have a Viewer by August
  • Possible distinction: A Viewer - look at CRs one at a time. Dashboard - look at multiple CRs and act on them.

From 2018-06-14 call:

  • Jim: any project wanting to participate in the MyData consent receipt interop demo - we need you do do a mapping against the CR fields - there is a spreadsheet!
  • Need to ensure that the Use Case spotlights the user-centric approach. A motivator to show vendor-vendor interop is to demonstrate industry resilience.
  • Since the CR will contain personal data (and probably sensitive data) we must avoid giving the impression that we are unware of risks and anti-patterns.
  • There are 10 weeks remaining until presentation day!
  • Next week's call:
    • Confirm the high-level scenario for the demo
      • Should this be limited to exchange of CRs? or showing data transfer that involves CRs
    • Discuss and finalize a sequence/interaction diagram
      • Confirm the CR-related roles required for the demo (Display-ers/dashboards, the Person, CR Issuers)
    • Richard Gomer is committed to the project (per Chris (smile) ) - will have input into the UX issues
      • The Consentua WebSDK demonstrator has embodied some of these concepts
    • Pre-work assignments (due for distribution to the WG by Tuesday):
      • John - will develop a draft sequence diagram
