Biometric Authentication API

Biometric software is a powerful tool used to confirm or determine someone’s identity based upon physiological or behavioral characteristics. These feature vectors are stored in a database for verification and identification purposes. Biometric verification involves comparing the person’s actual characteristics to stored information, and biometric identification compares the person’s biometric information to all of the biometric characteristics stored in the database. Biometric software that supports both biometric verification and biomatic identification is commonly available.

Types of Biometrics Software

There are many different types of biometric software.

Choices include:

Fingerprint Recognition Software

Eye Retina or Iris Recognition Software

Voice Recognition Software

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.

Some biometric systems are designed to detect and analyze the pattern of heat radiated by the human body. Others are designed to recognize and verify a user’s gait, computer keystrokes, odor, ear size, hand geometry, or palmprint. Biometric software for signature recognition and DNA verification are also available.
