A facial recognition system in Ireland has identified 62 cases of serious identity fraud since being introduced in 2012, saving the country millions of euros in fraudulent welfare payments.Niamh O'Donoghue, Secretary General of the Social Protection Department, told the Public Accounts Committee (PAC) that in dozens of the cases people were claiming multiple identities.The official added that overpayments of over 1 million euros (US$1 million) have been assessed, while claims worth a further 1.5 million euros have been stopped.O'Donoghue said 1.4 million ID cards have been issued using the technology since 2012, with this figure expected to reach 3 million by the end of 2016.O'Donoghue said that while the overall saving that will be made in terms of the cards reducing fraud can't be quantified, it will be “in the millions”.
