In the last year Europe has experienced the greatest influx of people seen since the second world war. The chancellor of Germany offered asylum to Syrians as part of the effort to assist those displaced by war. The number of known people who have entered Europe to claim asylum in 2015 exceeded 2015. With the discovery that a number of people were claiming to be Syrian when entering Europe countries a number of the EU states have started to use biometric technology including face detection software to identify where migrants have come from as part of the asylum claiming process. Sweden expects to deport up to 80,000 people after discovering that their asylum claims are not valid based on this and similar technology. Other European countries are expected to follow suit in 2016. Technology and digital records is advancing to the point where it is now possible to trace where a person has come from originally and where they have been. Sweden has seen the number of new migrants entering the country fall since it brought in systematic photo ID checks on travelers on January 4.
