Facebook is being hit with another lawsuit for amassing facial recognition data on potentially billions of people worldwide.

In the fourth case of its kind, an Illinois man filed suit against Facebook late last month, arguing that state law made the data collection an illegal imposition on his privacy. His complaint points out that Facebook engages in “actively collecting, storing, and using — without providing notice, obtaining informed written consent or publishing data retention policies — the biometrics of its users and unwitting non-users.” It also points out that Facebook has “created, collected and stored over 1 billion ‘face templates.’ ”
