  • A

    Automated Fingerprint Identification System (AFIS)

    The Automated Fingerprint Identification System (AFIS) is a biometric identification (ID) methodology that uses digital imaging technology to obtain, store, and analyze fingerprint data.

  • B

    bifurcation

    In the biometric process of fingerscanning, a bifurcation is a point in a finger image at which two ridges meet.

  • BioAPI Consortium

    The BioAPI Consortium is a group of over 90 organizations whose goal is to encourage and promote the growth of biometric technology by developing an industry-wide application programming interface (API.) The consortium's API defines how a software application interacts with a biometric verification device; it is compatible with different operating systems, vendor applications, and types of biometric technologies including voice and facial recognition, iris and retina scans, signature verification, hand and earlobe geometry, and fingerprint analysis.

  • biometric authentication

    Biometric authentication is a security process that relies on the unique biological characteristics of an individual to verify that he is who is says he is. Biometric authentication systems compare a biometric data capture to stored, confirmed authentic data in a database. If both samples of the biometric data match, authentication is confirmed.

  • biometric payment

    Biometric payment is a point of sale technology in which a customer submits biometric data, such as a fingerprint, to authorize the deduction of funds from a bank account... (Continued)

  • biometric verification

    Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits... (Continued)

  • biometrics

    Biometrics is the measurement and statistical analysis of people’s physical and behavioral characteristics.

  • Bring Your Own Authentication (BYOA)

    Bring Your Own Authentication (BYOA) is a computing concept in which employee-owned devices are used as authentication credentials within the enterprise.

  • C

    capture

    Capture is the process or means of obtaining and storing external data, particularly images or sounds, for use at a later time.

  • E

    electro-optical fingerprint recognition

    Electro-optical fingerprint recognition is a biometric technology that provides for the scanning, comparison, and identification of fingerprints without the traditional need for ink and paper.

  • F

    false acceptance (type II error)

    False acceptance, also called a type II error, is a mistake occasionally made by biometric security systems.

  • false rejection (type I error)

    False rejection, also called a type I error, is a mistake occasionally made by biometric security systems.

  • FIDO (Fast Identity Online)

    FIDO (Fast ID Online) is a set of security specifications for strong authentication. Unlike password databases, FIDO stores authentication data locally on the user device.

  • finger vein ID

    Finger vein ID is a biometric authentication system that matches the vascular pattern in an individual's finger to previously obtained data...(continued)

  • fingernail storage

    Fingernail storage is a method of writing data onto a human fingernail using a pulsed laser. The fluorescence of the nail, when exposed to ultraviolet (UV) light, is increased at points where data is written. Data can be read from the fingernail using a microscope while irradiating the nail with UV energy.
