Manchester Airport has announced a trial of retinal scanning for ‘volunteer’ passengers checking in. The retinal scanning technology is proven and is difficult to fool, although eye diseases can change the retina over time. The issues up for discussion are is it too intrusive, having a light beam shone into your eyes for ten seconds or so could be for some people, is it too expensive and what other systems should be in place to work with retinal scanning?
Fingerprint biometrics are being used in airport security and access control applications all over the world and could be a useful compliment to retinal scanning and other biometric human recognition checks. But, you may believe that fingerprint biometric systems are too easily duped? Perhaps in the past they have been ‘fooled’ as a story from Japan in early 2009 suggested. In that case some ‘special tape’ had been used by a woman with a false passport and a track record of illegal entry to the country to get through immigration controls which included a fingerprint scanner. This may suggest the sensor technology in the Japanese system was not up to scratch.
