Fingerprint Recognition Software
Fingerprint recognition software is designed for use with scanners that use electrical capacitance to sense the ridges of a person’s finger and produce a digital image. The digital images are then compared to a database with biometric information about authorized users.
Voice Recognition Software
Voice recognition software is also available. There are two types of products: automatic speaker verification (ASV) and automatic speaker identification (ASI). Both types of biometric software compare a person’s actual voice characteristics to stored information.
Retina Recognition Software
Retina recognition software and iris recognition software confirms or determines a person’s identity based upon eye characteristics. With retinal recognition, a person looks through a lens at an alignment target. With iris scanning, the person remains several feet away from the biometric device. Retina recognition is one of the most secure and reliable biometric techniques, but iris recognition systems are usually more cost-effective.
Facial Recognition Software
Facial recognition software is also commonly available. Some types of this biometric software uses the location and shape of specific facial features such as chin, eyes, eyebrows, lips, and nose. Other facial recognition biometric software performs an overall analysis of the face image.
