Applications and Privacy Issues with Sensor Nets

Jason Hong

Carnegie Mellon University

some applications
Some Applications
  • 911.net
    • Rapidly deployable sensor net for firefighters
    • Rapid response when an individual in danger
  • Families
    • Am I leaving with everything I came with?
  • Personal motivation
    • Help me be more green / more active
    • Combine with social web sites (FootPrints)
  • Smart Homes
    • Home monitoring of elderly (CMU QoLT)
    • Just moved, where’s my stuff?
    • Drunk again?
privacy and sensor nets
Privacy and Sensor Nets
  • Two separate notions
    • Privacy with respect to owners of sensor net vs users
  • For owners:
    • Transparency and accountability
    • Privacy policies
    • Protection at physical layer for plausible deniability
  • For users:
    • “Did you get there safely?” vs “Where are you?”
    • Pessimistic vs optimistic privacy
  • Will we trade privacy for safety, fairness, public good?
other issues to consider
Other Issues to Consider
  • How do mobile phones fit in?
    • Are people part of sensor nets too? (Gawker Stalker)
  • What is the deployment model / business model?
    • Home Depot model? Paid service? Public city infrastructure?
  • How to maximize public good?
    • Small percentage with Lojack decreases overall car thefts
  • What is the user interaction like?
    • Is it working? Broken? Dead batteries everywhere?
    • Don’t forget sense of play (De-Tour Guide)
    • Need rapid prototyping tools to assess utility before deploy
    • Please, no more smart fridges!!!
