EU pilots AI border agents to mine microexpressions


In 2018, the EU announced iBorderCtrl, a six-month pilot led by the Hungarian National Police to install an automated lie detection test at four border crossing points in Hungary, Latvia, and Greece. The system uses an animated AI border agent that records travellers' faces while asking questions such as "What's in your suitcase?". The AI then analyses the video, scoring each response for 38 microexpressions. Travellers who pass will be issued QR codes to let them through; those who don't will be referred to a human agent. The team behind the system, which includes researchers at Manchester Metropolitan University, believes it will be able to raise the system's accuracy to 85% - but even that rate will swamp the border with misidentified liars if the system is rolled out EU-wide.
