Presentation Transcript

  1. National Centre for     Geographic & Resource Analysis in Primary Health Care (GRAPHC) Enabling Location Privacy Without Loss of Location Accuracy Michael Hewett National Centre for Geographic & Resource Analysis in Primary Health Care (GRAPHC),Australian Primary Health Care Research Institute (APHCRI), Australian National University (ANU)

  2. Primary Health Care Research GIS Resource • Spatially enabling data • Providing spatial linking mechanisms • Improving availability of tools & processes • GIS skills resource • Web based mapping Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  3. Primary Health Care Research & Privacy • Especially important in Health Care Research context • Legal and Ethical Protections • Researchers • Doctors/Data Originators • Trust • Researchers need to Share Data • Research Validation • New research • Involves more than just the research data Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  4. Cartophobia Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  5. Privacy: De-identification • Replace name with patient ID. • Remove Location • Use coordinate • Use Suburb or Postcode • Replace location with ID Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  6. Privacy: Coordinates?....... Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  7. Privacy: Suburb or Postcode?....... Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  8. Privacy: Location ID? • Location ID • Cross Linking • Must link to location for processing • GeoHash • Decodable To Location • Encryption • Decryptable • Must be decrypted before Analysis • Cross linking even without decoding Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  9. Other Options • Ethical/Legal clearance to use addresses and coordinates • Pre-aggregation • Third party secure data environments Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  10. So where next? Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  11. - Location without Context- Context without Location GRAPHC - Location User - Context GTAG Patient details • GTAG • Address/Location Name • Point location Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  12. Point LocationsHigh Resolution Analysis And Resampling Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  13. Address Registration Address GTAG Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  14. Authorisation And Geocoding Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  15. Analysis/Geoattribution GTAGs Analysis Result Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  16. Leveraging ESRI Technology GRAPHC Databases & Geodatabases ArcGIS Desktop - Map And Data Layers Model Builder – Geoprocessing Models Custom Code and Scripts leveraging ESRI APIs & libraries Independent Custom Code ArcGIS Server Custom Web APIs GRAPHC ArcGIS Online Maps & Apps Health Landscapes External ESRI users - Desktop, Online, Explorer, etc GRAPHC Custom Tools & Apps 3rd Party Custom Tools & Apps Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  17. Accessing GRAPHC Data Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  18. Indirect Engagement • GTAGs are already being engaged by: • A major data extraction company • A secure data service environment • Several Medicare Locals • Other Universities • Research Projects • Under Review for use by: • CSIRO, CRCSI, • Potential for anywhere that location privacy is important Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  19. How Much does this cost???? • Free location registration and administration. • Cost Recovery Model • Community Cost Sharing • Commercial Use – Contact GRAPHC Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)

  20. Live Demo Michael Hewett, GRAPHC (http://graphc.aphcri.anu.edu.au)
