Given that biometrics is a truly unique identifier, concerns about privacy and data sharing are common. IMS’s fingerprint images are not saved, but digital mapping templates of each fingerprint are saved in a digital format. As a result, there is no actual fingerprint saved in the system, but a digital template of different regions of a user’s finger. Unique algorithms rate the likelihood of matches against this template. IMS biometrics uses multi-spectral imaging, adding additional levels of ID security in that it can detect living flesh from non-living flesh or other organic or synthetic materials. Prevent “spoofing” or the creation of a “gummy fingerprint”.
Many gate access implementations result in fingerprint templates being destroyed within a period of time once a ticket is activated and associated with an individual. Most other applications involve associating a fingerprint with a customer account, not unlike associating a credit card to an individual. In both instances, the advantage of biometrics is the difficulty in duplicating or replacing the identifier (a fingerprint) once an account association is made.
