Behind the Technology

Problems of inaccuracy resulting from oily, soiled or cracked skins, a major impediment in fingerprint technology, have recently been tackled by the development a contactless capturing device which translates the characteristics of a fingerprint into a digitised image.

Because of the ability of the Biometric Solution to be customized for individual business and institution needs, these systems can be the key to business that is more efficient in many ways:

Abstract on Artificial "Gummy" Fingers, potential threats caused by something like real fingers, which are called fake or artificial fingers, should be crucial for authentication based on fingerprint systems. Security evaluation against attacks using such artificial fingers has been rarely disclosed. Only in patent literature, measures, such as "live and well" detection, agai英语论文网 【http://www.51lunwen.org】nst fake fingers have been proposed.

However, the providers of fingerprint systems usually do not mention whether or not these measures are actually implmented in emerging fingerprint systems for PCs or smart cards or portable terminals, which are expected to enhance the grade of personal authentication necessary for digital transactions. As researchers who are pursuing secure systems, we would like to discuss attacks using artificial fingers and conduct experimental research to clarify the reality.

Other agencies and businesses are starting to see uses for fingerprints besides criminal records. Since it is almost impossible to steal a person's fingerprints, why not use this as a "key" that can grant access to certain areas and systems? PINs and passwords can be forgotten; fingerprints cannot. ATMs, computers and even cell phones

are being equipped with these fingerprint authentication devices to add an extra layer of security. Online companies that accept credit cards online for transactions are pressing for this technology since it could drastically cut back on fraud. There are even plans for using fingerprints to collect federal assistance money and filing taxes. With technological breakthroughs and drops in prices, fingerprint authentication has found its way into our everyday lives. 

Fingerprints are formed before birth, during the development of the hands. Fingerprints aren't actually formed in the sk 本文来自：英语论文网 【http://www.51lunwen.org】
