GDPR-driven Change Detection in Consent and Activity Metadata

  1. 1. GDPR-driven Change Detection in Consent and Activity Metadata Harshvardhan J. Pandit, Declan O‘Sullivan, Dave Lewis ADAPT Centre Trinity College Dublin Dublin, Ireland The ADAPT Centre is funded under the SFI Research Centres Programme (Grant 13/RC/2106) and is co-funded under the European Regional Development Fund.
  2. 2. slide#2https://openscience.adaptcentre.ie GDPR General Data Protection Regulation ● Needs ‘valid‘ given consent ● Fines 4% of global turnover ● Record of processing activity ● Data Protection Ofcer to monitor compliance ● Demonstrate compliance → Past ● Plan & Maintain compliance → Future
  3. 3. slide#3https://openscience.adaptcentre.ie Research Area and Domain ● Express legal obligations → ODRL ● Infrastructure for GDPR compliance ● Metadata modeling, storing, and querying Provenance Metadata – Activity and Entity – i.e. Consent and Personal Data lifecycles
  4. 4. slide#4https://openscience.adaptcentre.ie State of the Art Provenance - PROV Ontology (PROV-O) ● OWL2 ontology to express provenance ● W3C Recommendation 30-APR-2013 ● Interaction between Activity, Entity, Agents ● Record history (past) https://www.w3.org/TR/prov-o/
  5. 5. slide#5https://openscience.adaptcentre.ie State of the Art Provenance - P-Plan ● Extension of PROV-O ● Represent ‘plan‘ that guided execution ● Model execution that is yet to happen (future) ● Common template ● Individual instantiations using PROV-O http://vocab.linkeddata.es/p-plan/
  6. 6. slide#6https://openscience.adaptcentre.ie State of the Art ODRL – Open Digital Rights Language ● Policy language ● Permissions and Prohibitions ● W3C Recommendation 15th February 2018 https://www.w3.org/TR/odrl-model/
  7. 7. slide#7https://openscience.adaptcentre.ie Representation of Metadata ●Consent → ODRL – An agreement between user and data controller or service provider – Express permissions and restrictions ●Provenance → P-Plan + PROV-O – What activities was the consent given for? – Express what is happening or has happened with the data
  8. 8. slide#8https://openscience.adaptcentre.ie Changes in Consent ● Previously, Sue gave consent to send ads using the email address [1] ● Later, this consent was revoked ● Expressing this as ODRL, we have two objects, where the permission rules is changed to a prohibition rule
  9. 9. slide#9https://openscience.adaptcentre.ie Capturing Changes in Consent
  10. 10. slide#10https://openscience.adaptcentre.ie Changes in Activities ● Email is used for tracking ftness (as account) ● Later, email is also used to send ads ● This is a change in the activities where the use of email has changed, and therefore may require an updated consent (change!) ● Expressing this using P-Plan allows representing it as an abstract model
  11. 11. slide#11https://openscience.adaptcentre.ie Capturing Changes in Activities
  12. 12. slide#12https://openscience.adaptcentre.ie Linking Changes ● We know that consent afects activities ● We also know that activities afects consent ● For compliance purpoes, how should this information be captured and represented?
  13. 13. slide#13https://openscience.adaptcentre.ie Linking Changes using Provenance Traces
  14. 14. slide#14https://openscience.adaptcentre.ie A more relevant ontology GDPRov – GDPR Provenance Ontology ● Separation between personal data and consent activities and entities ● GDPR terminology ● Published at PrivOn workshop co-located with ISWC 2017
  15. 15. slide#15https://openscience.adaptcentre.ie A more relevant ontology GDPRtEXT – GDPR ontology ● Defnes terms using skos:Concept ● Link related terms ● 200+ concepts for GDPR ● To be presented at ESWC2018 Resource Track
  16. 16. slide#16https://openscience.adaptcentre.ie Challenges at scale ● Detect changes ● Analyse changes ● Demonstrate changes were compliant ● Refect real-world use-cases
  17. 17. slide#17https://openscience.adaptcentre.ie Fallback Solution ● If this model is not feasible at scale, can we show it working over a model of the system? ● If the model of the system is compliant, is it sufcient to say the system is compliant? ● tldr; Show changes at the model level instead of instance level
  18. 18. slide#18https://openscience.adaptcentre.ie Potential Applications ● Privacy Policies on the Web ● Can we track how they change and what the change is using the approach described in this presentation?
