Police using facial recognition cameras at Victoria's busiest stations

Victoria Police declined to discuss the rate of false positives, other than to insist that "since the rollout of these [iFace] cameras in 2015, police have always had the ability to override any decisions made by the system at any time". "During offender processing at locations where an iFace camera is in use, there are a range of techniques in place to prevent someone being linked to the wrong image," the spokeswoman said. Victoria Police's iFace program uses algorithms to measure features such as face width and the distance between nose, eyes and mouth before comparing the image against the facial characteristics of known offenders to generate a match. It currently has no capability to run searches against CCTV footage or video, police say, because "all searches require a still image and are performed after an offence has occurred". Human rights and privacy advocates say there is not enough transparency surrounding the network, and some have called for tighter safeguards to ensure that vulnerable people are not unfairly targeted.
