  4. Introduction • There is a heightened level of wireless connectivity • Wireless networks are vulnerable to eavesdropping • Eavesdropping can infringe on location privacy

  5. Scenarios • Provider cross-referencing corporate info with public network info (that they serve) • Leveraging persistent addressing (MAC) • Monitoring an individual’s network access • Leveraging probe request frames (SSID) • Extrapolating provider network statistics • Leveraging packet sequence numbers

  6. Challenges • Balancing the need for names to address devices with keeping them from being identifiable by name • Discover and use resources without revealing the action or past history • Designing protocols to avoid leaking identifying information through physical characteristics of transmissions, control information, etc.

  7. Conclusions • “This paper argues that wireless networks pose new threats to privacy” • Prior efforts to anonymize communication still leak explicit identifiable information

  8. Other Methods • Foursquare, Facebook • Seekdroid, Lookout, Find My iPhone • Google Maps, WiGLE, Skyhook

  9. Conclusions • Wireless location privacy issues will only continue to grow as an issue as wireless connectivity increases • Security is limited by our standards and protocols, but also by human vulnerability
