BIOMETRIC FINGERPRINT TERMS R
Radio Frequency Identification (RFID)
Technology that uses low-powered radio transmitters to read data stored in a transponder (tag). RFID tags can be used to track assets, manage inventory, authorize payments, and serve as electronic keys. RFID is not a biometric.
Receiver Operating Characteristics (ROC)
A method of showing measured accuracy performance of a biometric system. A verification ROC compares false accept rate vs. verification rate. An open-set identification (watchlist) ROC compares false alarm rates vs. detection and identification rate.
Receiver Operating Characteristic Recognition
A generic term used in the description of biometric systems (e.g. face recognition or iris recognition) relating to their fundamental function. The term “recognition” does not inherently imply the verification, closed-set identification or open-set identification (watchlist).
The template and other information about the end user (e.g. name, access permissions).
The biometric data stored for an individual for use in future recognition. A reference can be one or more templates, models or raw images.
The number of pixels per unit distance in the image. Describes the sharpness and clarity of an image.
A minutiae point at the ending of a friction ridge, as illustrated below.
An image that includes fingerprint data from nail to nail, obtained by “rolling” the finger across a sensor, as illustrated below.
