Axon CEO Says Face Recognition Isn’t Accurate Enough For Body Cams Yet

Axon CEO Says Face Recognition Isn’t Accurate Enough For Body Cams Yet

Face recognition is coming to schools, stadiums, and airports, but surprisingly not to body cameras—yet. On an earnings call Tuesday, Rick Smith, CEO of Axon, one of the largest body camera manufacturers in the US, said the reason was simple: In addition to privacy and policy concerns, face recognition isn’t accurate enough.

The “accuracy thresholds,” Smith said on the call, aren’t “where they need to be to be making operational decisions off the facial recognition.”

He continued, “This is one where we think you don’t want to be premature and end up either where you have technical failures with disastrous outcomes or… there’s some unintended use-case where it ends up being unacceptable publicly in terms of long-term use of the technology.”

Smith may be right that a premature rollout would sour people to the technology, but frankly, there’s plenty to be freaked out about already.

In the UK, police used face recognition software that falsely flagged thousands of people at a sporting event as being criminals. The false positive rate was a staggering 90 per cent. In the U.S., Amazon’s facial recognition software, called Rekognition, drew massive criticism after the ACLU used it to match congress members against a database of criminal suspects. Rekognition falsely claimed 28 congress members were in the database. Police officials in the UK have said they’ll refine their technology to improve its accuracy, while Amazon countered the ACLU’s results.

Amazon’s AI chief emphasised that the ACLU’s experiment considered a “match” to occur anytime the software was 80 per cent confident a congressperson was in the arrestee database. Amazon, however, recommends police use a confidence threshold of at least 95 per cent. With this guidance, police using Rekognition wouldn’t necessarily have considered many of the congresspeople to be a match.

Countering Smith’s thesis, law enforcement agencies and Silicon Valley both seem fairly set on face recognition as an inevitability, despite bad press about inaccuracies. And to be clear, confidence is not accuracy. Even if the ACLU raised its threshold to 99 per cent, Rekognition would still be incorrect in saying there was even a single match.

Accuracy in facial recognition is essential. But, in the context of policing, there are innumerable caveats. It’s not reassuring to anyone to hear that the police are working towards better omni-surveillance. It’s good if tech companies are concerning themselves with public opinion, but there’s no indication that will deter them from building a surveillance state.
