What:

Sterling Crispin’s “Data Masks” are haunting portraits that don’t actually depict any one person. Instead, they use raw data to show how technology perceives humanity. Reverse-engineered from surveillance face-recognition algorithms and then fed through Facebook’s face-detection software, the Data Masks “confront viewers with the realization that they’re being seen and watched basically all the time,” Crispin says.

How:

“Facebook actually makes masks out of everyone’s faces,” the artist explains. The social network analyzes every face that appears in photos on its servers and renders them into three-dimensional models. “It’s happening whether you get tagged in the photo or not,” Crispin says.
