False Acceptance Rate (FAR)

A critical metric in digital identity verification systems, the False Acceptance Rate (FAR) measures the rate at which unauthorised users are incorrectly granted access. In simpler terms, it represents the percentage of times a system mistakenly identifies an imposter as a legitimate user. A low FAR indicates a more secure system, while a high FAR signifies a higher risk of unauthorised access.

Understanding False Acceptance Rates

FAR essentially reflects the number of false positives within a digital identity verification system. Imagine someone trying to unlock your phone with facial recognition. A false acceptance occurs if the system unlocks the phone for an unauthorised person whose face is mistakenly recognised as yours.

Calculating False Acceptance Rate

FAR is calculated as a percentage using the following formula:

FAR = (Number of false acceptance ÷Total Number of Unauthorised Access Attempts) × 100%

The Importance of Minimizing FAR

A low FAR is essential for robust digital identity security because it minimises the chances of:

• Security Breaches: Unauthorized access to accounts or systems can lead to data breaches and financial losses.
• Identity Theft: A high FAR can facilitate identity theft attempts, where imposters gain access to user accounts.
• Erosion of User Trust: Frequent security breaches due to high FAR can erode user trust in digital identity verification systems.
