FINGER RECOGNITION SYSTEMS
With the advancement of technology biometric systems became more advance for Digital Security, until now probably you have heard about fingerprint recognition in which the requirement was to touch the device and you are authenticated. But the latest approaches show that we could have a finger scanner with no-touch activity, NIST (National Institute of Standards and Technology) has just started funding a number of startup companies to develop a touchless finger recognition system. In contactless biometric security, personal presence is needed, but from meters away. Special Fingerprint scanners have already been used by Samsung and Apple in their smartphones to authenticate users, and in the near future, fingerprint scanners are believed to be part of many other locked devices that could be unlocked using fingerprints. Just to add an extra layer of authentication, fingerprint scanners are used to authenticate between two fingers. Fingerprint sensors are one of the most commonly used identification systems in biometric technology or access control technology. Fingerprints require the comparison of print patterns, the patterns include minutia points and aggregate characteristics of the ridge, and they are the unique features present in the patterns. To employ successful imaging technology for fingerprint scanners we also need to know about the skin properties and patterns of the skin.
