Applications and Privacy Issues with Sensor Nets, at Microsoft Faculty Summit 2007
Applications and Privacy
Issues with Sensor Nets
Carnegie Mellon University
– Rapidly deployable sensor net for firefighters
– Rapid response when an individual in danger
– 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
• 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
• 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!!!
