Strength of function for authenticators

Read the latest draft!

NIST staff are reviewing comments and will release updates soon. The authors can be reached at sofa@nist.gov.

The basics

The Strength of Function for Authenticators – Biometrics (SOFA-B) Discussion Draft is the next step in NIST’s efforts to produce a framework to evaluate and compare the strength of authentication solutions. The SOFA-B model incorporates three aspects: matching performance, presentation attack detection (aka spoof detection), and Effort (to break a system). The ultimate goal of this work is a measure for comparing and combining authentication technologies.

Approach

NIST has engaged the community to develop a document that will best support decision-making around biometric authentication technologies. To do so, the authors solicited feedback via GitHub. GitHub has enabled NIST to engage the community in near real time to more quickly create a better product.
