An airline scans your face. You take off. But few rules govern where your data goes

The program makes boarding an international flight a breeze: Passengers step up to the gate, get their photo taken and proceed onto the plane. There is no paper ticket or airline app. Thanks to facial recognition technology, their face becomes their boarding pass. The problem confronting thousands of travellers, is that few companies participating in the program, called the Traveller Verification Service, give explicit guarantees that passengers’ facial recognition data will be protected. And even though the program is run by the DHS, federal officials say they have placed no limits on how participating companies can use that data or store it, opening up travellers’ most personal information to potential misuse and abuse such as being sold or used to track passengers’ whereabouts. <br/>
