RFID Applications Presented by: Renato Casipe Date : May 3, 2010
RFID (Radio Frequency Identification) • Radio Frequency Identification • Tags objects • Identifies object
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.”
RFID Already a Part of Our Lives • Keyless car entry • Gas payment (i.e. Speedpass) • Ski pass • School ID
Sample RFID Applications Credit Card
Sample RFID Applications Toll Pass
Sample RFID Applications Passport
RFID System Structure Yan et al., 2009
RFID Components • Tag • Coupling Units • Chips • Sensors • Electronic Product Code (EPC)
RFID Components • Reader • Read • Write • Mobile • Fixed
RFID Components • Antenna • Transducer
RFID Components • Backend System
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
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).
EPC EPCglobal.org, 2010
EPC Minimalist Approach • Functionality • away from tag • Into the network • Electronic Product Code (EPC) • Object Name Service (ONS ) • SAVANT • Transponders
Major RFID Adopters • Wal-Mart • 22 distribution centers • 15,000 suppliers • $2 fee/pallet without RFID tag • By 2010
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
Major RFID Adopters • Others • USDA • Animal tagging • MasterCard and Visa • Paypass and Wave • Sun Microsystems • Java System RFID Software
ROI Seen • Tagging at container level • Item level for higher value stuff • Sensors
RFID Adoption Barriers • Privacy Concerns • Cost • ROI • Business Processes Change • Standards
Privacy Concerns Syverson et.al., 2005
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
Privacy Concerns • Encryption algorithms • Traditional Security features.
Security Threat • Corporate espionage threat • Competitive marketing threat • Infrastructure threat • Trust perimeter threat
Privacy Threat • Action • Association • Location
Privacy Threat • Preference • Constellation • Transaction
Privacy Threat • Breadcrumb • Cloning
Some Solutions to Privacy Threat • Killing • Sleeping • Password • Pseudonyms
Some Solutions to Privacy Threat • Encryption • Proxy • Blocking
Specific RFID Applications • Product Monitoring • Online Payment • Attendance System
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
System Operation • Registration Phase • Transaction Phase • Reset Phase
