Presentation Transcript

  1. RFID Applications Presented by: Renato Casipe Date : May 3, 2010

  2. RFID (Radio Frequency Identification) • Radio Frequency Identification • Tags objects • Identifies object

  3. RFID and The “Internet of Things” (IoT) • Key enabler • MIT’s Auto-ID Center (1999) • Internet of Things refers to a ubiquitous network society in which a lot of objects are “connected.”

  4. RFID Already a Part of Our Lives • Keyless car entry • Gas payment (i.e. Speedpass) • Ski pass • School ID

  5. Sample RFID Applications Credit Card

  6. Sample RFID Applications Toll Pass

  7. Sample RFID Applications Passport

  11. RFID System Structure Yan et al., 2009

  12. RFID Components • Tag • Coupling Units • Chips • Sensors • Electronic Product Code (EPC)

  13. RFID Components • Reader • Read • Write • Mobile • Fixed

  14. RFID Components • Antenna • Transducer

  15. RFID Components • Backend System

  16. Tag Types • Passive • No battery or onboard power source and • Backscatter • Active • Onboard power source • can transmit signals autonomously • Semi-active / Semi-passive • Small battery

  17. Tag Classes

  18. Tag Memory • Passive tags can typically contain about 32 bits to 128 kilobyte of data. • Active tags have up to 1 Megabyte of memory (AIMGlobal, 2006).

  19. Tag Frequencies

  20. EPC EPCglobal.org, 2010

  21. EPC Minimalist Approach • Functionality • away from tag • Into the network • Electronic Product Code (EPC) • Object Name Service (ONS ) • SAVANT • Transponders

  22. Major RFID Adopters • Wal-Mart • 22 distribution centers • 15,000 suppliers • $2 fee/pallet without RFID tag • By 2010

  23. Major RFID Adopters • Department of Defense • RFID tagging will be required for all DoD manufacturers and suppliers packaged within • palletized unit • to any DoD location

  24. Major RFID Adopters • Others • USDA • Animal tagging • MasterCard and Visa • Paypass and Wave • Sun Microsystems • Java System RFID Software

  25. ROI Seen • Tagging at container level • Item level for higher value stuff • Sensors

  26. RFID Adoption Barriers • Privacy Concerns • Cost • ROI • Business Processes Change • Standards

  27. Privacy Concerns Syverson et.al., 2005

  28. Privacy Concerns • Should EU RFID policy draft be implemented • 40% no; 15% Yes; 25% Needs modification; 20% don’t know (RFID journal poll). • New Hampshire HB 478 (vote of 186-170) • Notification • Disable on demand • Human implantation on consent • No tags on state issued id’s. • o

  29. Privacy Concerns • Encryption algorithms • Traditional Security features.

  30. Privacy Concerns

  31. Security Threat • Corporate espionage threat • Competitive marketing threat • Infrastructure threat • Trust perimeter threat

  32. Privacy Threat • Action • Association • Location

  33. Privacy Threat • Preference • Constellation • Transaction

  34. Privacy Threat • Breadcrumb • Cloning

  35. Privacy Threat

  36. Some Solutions to Privacy Threat • Killing • Sleeping • Password • Pseudonyms

  37. Some Solutions to Privacy Threat • Encryption • Proxy • Blocking

  38. Specific RFID Applications • Product Monitoring • Online Payment • Attendance System

  39. RFID in Product Monitoring

  46. RFID in Online Payment • Motivating Scenario • Renato forgot his credit shopping at Lowe’s. • A miscreant consequently picks up Renato’s credit card and uses it for unauthorized purchases online • Renato lost mental peace, and credit card company waste resources investigating the dispute. • $11.6 Billion online payment transaction on 2009

  47. Current credit card transaction for remote shopping

  48. Proposed architecture for remote credit card transactions

  49. System Operation • Registration Phase • Transaction Phase • Reset Phase

  50. Role of mobile-phone
