"In this age of terrorism and identity theft, many organizations want a fast, secure way of verifying that you are who you say you are. Identification is a pressing problem all over the world, so it’s no wonder that an IEEE journal that concentrates on this field turned out to be the most-cited journal in 2004.
Passports, driver’s licenses, and other government-issued picture IDs no longer suffice, because they can be readily forged. Automated face recognition, fingerprints, voice identification, corneal or retinal scans, and DNA analysis can identify individuals effectively, but they are too slow for high-volume use, as when thousands of passengers are being screened by airport security. At its core, each of those biometric techniques relies on some form of pattern recognition. A person could be recognized, for example, by the shape and highlights of the face or the colors and shapes in a cornea." [more]
