Questions answered in this file

Can facial recognition identify a suspect with certainty?

No. It produces ranked candidate matches that must be reviewed and independently corroborated before anyone is treated as identified.

Is facial recognition biased?

NIST testing found accuracy varies between algorithms, with some showing higher error rates for certain demographic groups.

Does photo quality affect facial recognition?

Greatly. Blurred, angled, poorly lit or low-resolution old photographs produce much less reliable results than modern frontal images.

Have facial recognition errors caused wrongful arrests?

Yes. Several U.S. wrongful arrests have been linked to over-reliance on facial recognition without adequate further investigation.

Should I publish a name suggested by an online face search?

No. Such tools can misidentify people; pass potential leads to investigators instead of publishing them.
