Facial recognition technology can be helpful in identifying possible suspects or persons of interest by performing a comparative analysis of facial attributes observed in digital images. The technology uses biometric algorithms in combination with trained analysts to compare distinguishing characteristics of a subject’s face, cross-referenced with existing databases of images. While human review in this process is imperative, the software can provide informative leads for further investigation.

This document provides a discussion of concepts and issues relevant to the accurate and ethical use of facial recognition technology.
