A privacy group has cited concerns over the expansion of biometric airport solutions.Officials from the NGO Electronic Privacy Information Center are concerned over biometric boarding pilots being launched by Jet Blue and Delta airlines in the US.”Implementation of the use of biometrics need to be scrutinized very closely,” said Jeramie Scott of the Electronic Privacy Information Center, to CBSNews. He said he is worried about the use of personal identifiers that cannot change. “Increasingly, as we consolidate biometric data into big databases and we use it more and more, those databases will become targets, and the risk of data breach increases greatly,” Scott explained. However, US Customs and Border Protection has clearly stated it's not using these devices to store photos of U.S citizens and insists privacy is a priority.
