Legislators in San Francisco have voted to ban the use of facial recognition, the first US city to do so.
The emerging technology will not be allowed to be used by local agencies, such as the city’s transport authority, or law enforcement.
Additionally, any plans to buy any kind of new surveillance technology must now be approved by city administrators.
Opponents of the measure said it will put people’s safety at risk and hinder efforts to fight crime.
Those in favour of the move said the technology as it exists today is unreliable, and represented an unnecessary infringement on people’s privacy and liberty.
In particular, opponents argued the systems are error prone, particularly when dealing with women or people with darker skin.
“With this vote, San Francisco has declared that face surveillance technology is incompatible with a healthy democracy and that residents deserve a voice in decisions about high-tech surveillance,” said Matt Cagle from the American Civil Liberties Union in Northern California.
“We applaud the city for listening to the community, and leading the way forward with this crucial legislation. Other cities should take note and set up similar safeguards to protect people’s safety and civil rights.”
The vote was passed by San Francisco’s supervisors 8-1, with two absentees. The measure is expected to be officially passed into city law after a second vote next week.
