In San Francisco, government agencies are no longer allowed to use face recognition to identify citizens. The municipality of the American city has agreed, writes The Verge .

It is the first time that a city in the United States has voted for such a ban.

The ban was proposed by alderman Aaron Peskin. "This is not a policy to combat technology," he says. "But face recognition is dangerous and oppressive in a unique way."

The police can no longer just use face recognition to detect suspects in San Francisco. The ban will come into effect in a month.

Bodies wishing to use other eavesdropping technology must now be approved by a special council. Similar rules were already in force in other American cities.
