Facial recognition technology gains popularity with police, intensifying calls for regulation

Some police services in Canada are using facial recognition technology to help solve crimes, while other police forces say human rights and privacy concerns are holding them back from employing the powerful digital tools.

It's this uneven application of the technology — and the loose rules governing its use — that has legal and AI experts calling on the federal government to set national standards.

"Until there's a better handle on the risks involved with the use of this technology, there ought to be a moratorium or a range of prohibitions on how and where it can be used," says Kristen Thomasen, law professor at the University of British Columbia.

As well, the patchwork of regulations on emerging biometric technologies has created situations in which some citizens' privacy rights are more protected than others.
