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.”

    Some developed countries are far from leading the way when it comes to making road infrastructure safe. In fact, says the Road Safety Foundation's Joanne Hill, they learn a lot from what is happening in emergent nations. A new report from the Road Safety Foundation, 'Saving Lives, Saving Money - the costs and benefits of achieving safe roads', makes some startling assertions about attitudes to road safety. Although concerned predominantly with the UK, there are some universal lessons to be learned, accordin

Public-private partnerships (P3s) are becoming increasingly favoured as a means of cost-effectively delivering much-needed public transit projects across the US. Previously, researched examples have tended to be on the large-scale while information on the potential for smaller, more localised schemes has been comparatively sparse.

    McCain is to upgrade San Francisco’s traffic signal infrastructure through the introduction of 400 M advanced transportation controller (ATC) cabinets over the next three years. Reza Roozitalab, McCain’s vice president of hardware engineering, says: “Our M ATC cabinet features two front side-by-side doors, ideal for areas with narrow sidewalks so maintenance teams can work inside without completely blocking the walkway.” Also, the M ATC cabinets feature a ‘lamp out monitoring algorithm’ which identifies
