What is Biometric Fingerprint Scanning?
Fingerprint scanning is a standard biometric method that authenticates a user’s identity based upon who they are. Even though authentication using fingerprint scanning attempts to verify identities by using a completely unique characteristic, it is not 100% secure or reliable. A user’s fingerprint consists of a number of ridges and valleys on the upper skin layer. A fingerprint scanner plate using optics or capacitance collects a print sample of the pattern of ridges and valleys, converts the pattern to a number or algorithm, and compares it to other stored templates. There are two basic types of fingerprint scanners, dynamic and static, with the latter being easier to defeat because a print can be extracted from another object and transferred to the scanner. The dynamic scanner uses a small slit or opening to capture prints, which makes it much more difficult to defeat. Circumventing fingerprint scanners is possible because optical scanners can’t always distinguish between a picture o
