"This year we'll begin testing a machine learning-based age estimation model in the U.S.," wrote Jenn Fitzpatrick, SVP of Google's "Core" Technology team, in the blog post. The Core unit is responsible for building the technical foundation behind the company's flagship products and for protecting users' online safety.
"This model helps us estimate whether a user is over or under 18 so that we can apply protections to help provide more age-appropriate experiences," Fitzpatrick wrote.
