Privacy and RFID Chips By Ayesha Begum
Agenda • What is RFID? • How does it work? • Types of RFID tags • RFID’s common uses • Benefits of RFID • Privacy and Security risks • Solutions to privacy threats
What is RFID? • Radio frequency Identification: technology that uses radio waves to exchange data between a reader and an electronic tag attached to an object, for the purpose of identification and tracking. - Wikipedia

Other points: • Chip size: about a rice grain to about a dime • Costs: 50c to $50 • depends on size, volume, and sophistication
Types of RFID • Based on mobility: • Fixed • Toll tags • Mobile • Handheld readers = reader
Types of RFID (2) • Based on performance: • Active • Battery powered • Long-distance reader • 3-8 years life • Passive • Non battery powered • Short-distance reader • Up to 10 years life
RFID all around you! • RFID credit cards • Employee badges • Toll passes • Passports • Movie tickets
For the common good • patient identification • animal tracking • Electronic Product Code (EPC) • robbery detection
Privacy and Security Risks • Privacy Risks • Rogue scanning • Eavesdropping • Security Risks • Identity theft • Tracking
Technical Solutions • ‘Kill’ and ‘sleep’ tags • Brute-force methods • Break or tear object • Place cover around object
Other Solutions ? • Educate: not all RFID bad • Demand/support legislation on RFID • Legislate applications, not technology
