Transcript

  • 1. Applications and Privacy Issues with Sensor Nets Jason Hong Carnegie Mellon University
  • 2. 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?
  • 3. 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?
  • 4. 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!!!
