The cameras that know if you're happy - or a threat
Facial recognition tech is becoming more sophisticated, with some firms claiming it can even read our emotions and detect suspicious behaviour. But what implications does this have for privacy and civil liberties?
Facial recognition tech has been around for decades, but it has been progressing in leaps and bounds in recent years due to advances in computing vision and artificial intelligence (AI), tech experts say.
It is now being used to identify people at borders, unlock smart phones, spot criminals, and authenticate banking transactions.
But some tech firms are claiming it can also assess our emotional state.
Since the 1970s, psychologists say they have been able to detect hidden emotions by studying the "micro expressions" on someone's face in photographs and video.
Algorithms and high definition cameras can handle this process just as accurately and faster, tech firms say.
"You're already seeing it used for commercial purposes," explains Oliver Philippou, an expert in video surveillance at IHS Markit.
