Transcript

  • 1. Expressive RFID data access policies for thePharmaceuticals supply chainMiguel Pardal, Mark Harrison, Sanjay Sarma, José Alves MarquesConsulting
  • 2. Traceability queries
  • 3. http://trakchain.net/
  • 4. US Pharma supply chain
  • 5. Threats• Prevent illegitimate products from enteringthe supply chain• Returns of counterfeit or stolen products inreplacement of legitimate products through awholesaler• Criminal wholesalers orpharmacists/pharmacies.
  • 6. US Pharma numbers• 1,400 Manufacturers• 70 Distributors– Big 3• 166,000 Pharmacies
  • 7. DataMatrix & RFID• You can have both 2D barcodes and RFID– GS1 compatibility layer• Industry has chosen barcodes foritem level identification
  • 8. Point-of-Dispense AuthenticationEuropean model
  • 9. European Stakeholder Model“ensuring patients have access to safe medicines”
  • 10. ESM Euro Hub
  • 11. Document-based electronic Pedigree“US” modelCA, FLDPMS
  • 12. Network-centric electronic PedigreeEPC IS
  • 13. Prototype
  • 14. Data capture screen
  • 15. Manufacturer viewThe manufacturer can see its own events andthe receiving event of the distributor
  • 16. Distributor viewThe distributor can see all the history prior toacquisition of the drug and its own events.
  • 17. Pharmacy viewThe pharmacy sees all the chain-of-custodyevents only for the product they receive
  • 18. PoD vs DeP vs NeP
  • 19. Classification
  • 20. Capture storage
  • 21. Capture cost
  • 22. Query cost
  • 23. DeP required secure connections
  • 24. PoD and NeP secure connections
  • 25. Conclusions• PoD is the most lightweight approach– stores less information– limited number of secure connections• DeP stores the most data– partial pedigrees– requires 10 times more secure connections• NeP is a middle ground between PoD and DeP– stores more data than PoD– semi-centralized architecture minimizes secure connections– same infrastructure – EPC IS and the EPC network – can supportmultiple applications– start with PoD and later evolve to full pedigree
