Frequently Asked Question

What are Plurilock’s false acceptance and false rejection rates?

Plurilock authentication boasts industry-leading accuracy in behavioral biometric authentication.

The false acceptance rate (FAR) and false rejection rate (FRR) metrics are typically applied to traditional biometric solutions, which unlike Plurilock rely on one momentary identity signal like a lone fingerprint scan. As a result, these metrics do not directly apply to Plurilock, which uses multiple identity signals analyzed over time.

The introduction of time into the calculation means that Plurilock has the advantage of being able to analyze a broader terrain of data, making identification easier and any single moment of data less critical to the final decision.

In a typical Plurilock deployment in which Plurilock's role is to provide MFA capability, Plurilock’s decision is paired with other identity factors like login credentials and step-up authentication. In these situations, practical FAR and FRR in the literal sense are effectively zero.
