False Rejection

Definition - What does False Rejection mean?

False rejection occurs when a biometric device rejects a genuine user and incorrectly labels that user as an intruder. Biometrics identifies unique physical traits to authenticate users.

The concept of utilizing distinguishing human physical traits as a mode of authentication is termed as biometrics. False rejection happens when a genuine user is rejected by the biometric system which treats him as an intruder. The accuracy of a biometric device is judged by its false rejection rate.

Techopedia explains False Rejection

The values gathered by a biometric system can produce a more accurate analysis by increasing the number of attempts by the same individual. Failure to acquire accurate data is one of the most important causes for false rejection. Dirty fingers used during fingerprint recognition can cause the device to interpret the print as not belonging to the user. Fingerprinting can also be affected by misplacing a finger on the sensor or changes in the skin as a result of skin conditions or wounds. Similarly, facial recognition systems needs a high-quality picture and ample lighting. The false rejection rate may also be affected by the time between analyses of a user; frequent users have lower FRRs compared to infrequent users.
