FREL stands for False Reject Error Level. It is a term used in the field of biometric systems and refers to a type of error that occurs when a biometric system fails to properly identify or recognize a valid user or input as authentic. It is the opposite of a false accept error, where the system incorrectly identifies an unauthorized user as valid.
In biometric systems, such as fingerprint scanners or face recognition software, the FREL is an important metric used to measure the accuracy and reliability of the system. It represents the percentage of times the system wrongly rejects a valid identification attempt. A lower FREL value indicates a more accurate and efficient system.
The FREL is influenced by various factors, including the quality of the biometric sample, the complexity of the algorithm used for identification, and the threshold set for acceptance. If the system's threshold for acceptance is set too high, it can lead to a higher FREL because valid inputs may not meet the criteria for identification. Conversely, if the threshold is set too low, it can increase the risk of false accept errors.
To improve FREL, biometric system designers and developers often employ various techniques such as enhancing the quality of biometric samples, refining identification algorithms, and adjusting acceptance thresholds. By minimizing FREL, biometric systems can achieve higher accuracy, reliability, and security, ensuring that only authorized users are granted access.
