Boleh Biometrics
Boleh Biometrics is a company based in Australia that provides Biometrics Solutions for companies using fingerprint technology. Their main focus is to provide education and understanding as to how fingerprint technology works to help allay any fears or skeptisism AbOUT their systems and products.
The Human Fingerprint
The human finger has two features which are used by these fingerprint scanners to identify the difference between individuals. The first feature is the points of current on the surface of the finger which occur due to the concentration of nerve endings in that area . The other feature is the individual ridges, curves, gullys and marks on the fingerprint. When light is shone on the fingerprint, the light reflects off at different angles giving an individual light template.
The Internal Workings of the Device
To measure the current and light used to identify each finger, the electronics in the system use Transducers in order to capture the signal. This signal is then altered by an algorithm which abstracts a Vector which aptly models the input data taken from the transducers. This data is then stored in a Look up Table so that when verification mode is entered The Vectors can be matched.
