This paper looks at privacy issues with cell phone cameras and similar gadgets.

Policy Relevance

Technology could be used to ease privacy concerns.

Main Points

  • Cell phone cameras, voice recorders, and other small devices that can travel anywhere make it more likely that privacy violations will occur.

  • Technology can help reduce privacy concerns. Recorded images can be encrypted, so that any of the people in a recording could veto its public release at any time.
    • No event could be recorded without the consent of everyone present.
    • A person’s decision to keep information private would be confidential.

  • New laws could recognize this technology to buttress privacy.

  • This technology is less restrictive than total bans on recording devices in an area, or laws banning recording entirely.
