San Francisco bans facial recognition software

Lawmakers in San Francisco have voted to outlaw the use of facial recognition tools.

It is a move which will have implications for police surveillance – and also for transit agencies.

It was reported last year that Bay Area Rapid Transit (7357 Bart) was considering the introduction of face recognition software on its cameras, for example – but Bart will not now be able to do so.

The 8-to-1 vote by the Board of Supervisors means San Francisco is the first city in the US to take this step – and the decision may form a precedent which other cities feel bound to follow.

Some police forces are already using live facial recognition (LFR) tools for surveillance.

Civil liberties group Big Brother Watch said last year that the London Metropolitan Police’s use of LFR in public spaces was “98% inaccurate – it identified people correctly only 2% of the time”. Elsewhere in the UK, South Wales Police’s live facial recognition “was inaccurate 91% of the time and had resulted in the misidentification of 2,451 people”.

In an interim report earlier this year, the UK government’s Biometrics and Forensics Ethics Group concluded: “There are a number of questions about: the accuracy of LFR technology; its potential for biased outputs and biased decision-making on the part of system operators; and an ambiguity about the nature of current deployments.”

The drive to create autonomous vehicles has caused a re-evaluation of what is needed to safely navigate today’s roads and the development of systems that can replace the driver in many scenarios. However, many manufacturers are not waiting for ‘tomorrow’ and are already incorporating these systems in their new cars as Advanced Driver Assistanc

    Despite law changes, drivers’ bad habits have been creeping back in. TRL’s Dr Shaun Helman tells Adam Hill why using a phone at the wheel is just as distracting as driving after a few drinks esearch from as far back as 2002 (see box) suggests that driving while making a phone call – either hands-free or holding a handset to your ear – creates the same amount of distraction as being drunk behind the wheel. While it is notoriously hard to predict how alcohol will affect an individual (due to the speed of
