They use CBP data for that program. They built the initial data set off of passport photos and then refined it using photos from the APC kiosks. You can opt out of biometric boarding but you cannot opt out of CBP sharing your data with 3rd parties.

No one raised a big stink or class action lawsuit about facial biometrics for boarding international flights using passport photos so now they are expanding it to domestic flights using drivers license photos. APC kiosks were the thin end of the wedge to building the biometric database that now enables you to enter the country without any paper document. Likewise, this program will in 2-3 years, allow TSA to identify you by photo without any documents.

Saw this at IAD today.

I am not sure how this supposed to speed up TSA Pre-Check process. Most times, the ID checking is not the bottleneck, it's the carry-on baggage scanning. Often, the TSA agent checking IDs has to stop so the bagger scanning can catch up.

Today at DFW D this was active and it allowed one to cut the significant PreCheck line.
