On the December 6, 2018 CIS WG call, we came to a rough consensus about what scenario we would like to show in the next version of the demo: The Kantara Initiative Privacy Control Panel system.

The following is a very early draft description of the system we will demonstrate at EIC 2019 and other events.


The main purposes of the Kantara Initiative Privacy Control Panel (Kantara PCP) system are a) to allow people to see, organize, find details via a ‘data processing receipt’ construct about the conditions under which they agreed to provide information for data processing; and b) to give them tools to investigate the data processing receipts they might have received or modify the permissions they granted when they initially shared the data for processing.

In the Kantara vision, whenever an individual is asked for their personal data, or whenever their personal data is acquired, a ‘data processing receipt’ is created by the data controller. The receipt includes details about the conditions under which the data was obtained: the privacy notices provided;  the lawful basis and purposes for collecting and processing data; the terms of the agreement and other metadata related to the interaction.

These data processing receipts could be offered by the data controller’s system to the individual for storage in their personal Privacy Control Panel application. 

Once the data processing receipts are in the personal PCP, the person can organize them and inspect them to ensure they are valid, current and actually represent what happened. 

The PCP gives the person tools to take action with the receipts including view, validity check, request the data, revoke consent, change permissions, or erase the data. In other words to exercise their data subject rights.

On the consent management platform and data controller system side, standard data processing receipt APIs could be offered. The PCP utilizes these APIs. 


The Kantara Members in the Consent & Information Sharing WG can participate in the demo by showing their product features that provide the different functions needed for the PCP demonstration, for example: the PCP dashboard, the data controller functionality to generate receipts, API platform provider, the ‘app’ used by the person, receipt viewer, receipt language translator, and so on.


The concept is that the products could, with very minor enhancements, be a component of the overall Kantara PCP system. We will showcase a future vision of the data processing ecosystem where the individual has more insight and control over their data.


The detailed demo functionality will also allow the CIS WG to identify needed changes to the core specification and additional specifications in the data processing receipt family.
