Fingerprint scanning is a standard biometric way in which authenticates a user's identity based on who they are. Even though authentication using fingerprint scanning attempts to verify identities by using a unique characteristic, it's not 100% secure or reliable.
A user's fingerprint includes a quantity of ridges and valleys around the upper skin layer. A fingerprint scanner plate using optics or capacitance collects a print sample from the pattern of ridges and valleys, converts the pattern to some number or algorithm, and compares it to other stored templates.
There are two basic kinds of fingerprint scanners, dynamic and static, using the latter being simpler to defeat because a print can be obtained from another object and used in the scanner. The dynamic scanner utilizes a small slit or opening to capture prints, which makes it much more hard to defeat.
Circumventing fingerprint scanners can be done because optical scanners can't always separate an image of the finger and the finger itself, and capacitive scanners can often be fooled with a mold of a person's finger. Some scanners have additional pulse and heat sensors to verify the finger is alive but even scalping strategies can be fooled by a gel or silicone printed mold over a real finger.
In addition to threats by posed attackers, fingerprint scanning has inherent problems, for instance in cold climates it might be too cold for fingerprints to register on the heat sensor or a finger might be too dry to close a capacitive circuit. Further, the (FAR) false accept rate and (FRR) false reject rate of fingerprint scanning compared to other biometric standards is sort of misleading due to the fact that much from the data originates from biased vendors. However, generally fingerprint scanning rates are superior to facial recognition rates but less favorable when compared to iris recognition or palm print scanning.
Remember that there isn't any perfect biometric system and every type has its own pros and cons, and should be evaluated based on its application.
To create home security systems more reliable, it's a good idea to mix biometric analysis along with other way of identification, like a password, or other multi-factor authentication systems.
We'd not recommend the fingerprint scanning biometric technique for locations or objects that need a high-level of security. If your building with highly sensitive information had fingerprint scanning as the only security device, then even a layman could lift a fingerprint from a car door, glass, etc., and gain access to the building.
Like passwords, fingerprint scanning is just a deterrent from access to information. Fingerprint scanners are utilized on many laptops today, however the primary security is through to lock it within the trunk when traveling or keep it kept in the house since with sufficient time, someone could break through password or fingerprint security.
