What do the Clearview.ai and PimEyes cases reveal about modern face-search engines?

They scrape billions of public photos to let anyone identify a stranger from a single image — Clearview.ai (~3 billion photos) was even used privately to ID a daughter's date; PimEyes (~900 million) surfaces a person's name, job, and more.

Both are face search engines built on mass-scraped portrait photos:

• Clearview.ai (Jan 2020): ~3 billion scraped portraits. In one real case, billionaire John Catsimatidis used it in a restaurant to identify his daughter's date ("I wanted to be sure he wasn't a charlatan").
• PimEyes (Jul 2020): ~900 million portraits. Upload a photo and it finds all publicly available images of that person, often revealing name, profession, and other personal info via the linked sites.
• FBI & driver's-license databases: the FBI queries state driver's-license databases for face searches, often without the subjects' consent, raising serious legal and ethical questions.

Switzerland's data-protection authority (EDÖB) has repeatedly warned about personality-rights violations from scraping face images off the internet without consent.

Tip: The shift here is from "the police can identify you" to "anyone with a photo can" — face-search engines democratise mass de-anonymisation.
