Drone Surveillance

New rules from the U.S. Federal Aviation Administration (FAA) for the commercial use of unmanned aircraft lighter than 55 pounds have opened the door to what could be a massive industry. It’s much bigger than delivery drones, which are not yet practical or legal in the U.S. First we’ll see more drones doing things like surveying real estate and inspecting infrastructure such as roofs, high bridges, cell towers, power lines, and wind turbines.

But our new drone reality has privacy advocates spooked: low-cost vehicles and sensors are likely to spur widespread adoption of a technology that can be used for persistent aerial surveillance, and bad actors could exploit gaps in existing privacy laws. It’s also not clear which government entities, if any, are responsible for addressing drone-related privacy concerns. The FAA has declined to make rules. The Federal Trade Commission, the U.S. government’s primary consumer privacy cop, is still exploring the issue. A few state laws have emerged to fill the void, but the overall landscape is inconsistent and unclear.

Drone industry advocates argue that these aircraft are not all that different from other technologies that could be used to conduct surveillance, and that state voyeurism and nuisance laws already in place will protect consumers.
