WA police is using live facial recognition to make arrests: This trial is testing privacy law

Western Australia Police Force recently announced a trial of live facial recognition to find persons of interest – the first Australian police force to do so; but Edith Cowan University’s Dr Nicola Lockhart argues that a ‘trial’ without any independently verification or evaluation is effectively a ‘product launch’, and sets out a range of measures the force could take to ensure the responsible governance of the new technology.

On June 22, Western Australian Police Force (WAPOL) became Australia’s first law enforcement agency to use live facial recognition technology to find persons of interest.

In its first week, media reports put the trial at more than 130,000 faces scanned and 33 alerts. It led to 18 arrests, along with engagements with registered sex offenders. Work that would have taken weeks of conventional investigative effort has been done in days by a single van.

The trial involves a clearly marked van with cameras driving around Perth and Mandurah. It scans the faces of everyone it passes, comparing them against a watchlist of about 4,000 people. It includes those with outstanding arrest warrants, reportable offenders, people subject to lawful exclusion orders, and missing persons.

But harder questions surround its governance. Can we really call it a ‘trial’? Who gets to authorise such deployments? And who checks the safeguards?

Any trial of new technology requires success criteria defined in advance, independent evaluation, and the possibility the technology won’t be deployed on a permanent basis after the trial completes. That’s not what seems to be happening in WA.
