SAN FRANCISCO - Facebook on Tuesday said facial recognition technology applied to photos at the social network will be an opt-in feature.
The change that began rolling out to users around the world came as the leading social network remains under pressure to better protect privacy and user data, including biometric information.
Nearly 2 years ago, Facebook introduced a face recognition feature that went beyond suggesting friends to tag in pictures or videos but could let user know when they were in images they had permission to see elsewhere on the service.
Facebook is doing away with a "tag" suggestion setting in favor of an overall facial recognition setting which will be off by default, according to a post by artificial intelligence applied research lead Srinivas Narayanan.
"Facebook's face recognition technology still does not recognize you to strangers," Narayanan said.
"We don't share your face recognition information with third parties. We also don't sell our technology."
People new to Facebook or who had the "tag" feature operating will get word from the social network about the face recognition setting along with an easy way to turn it on if they wish, according to Narayanan.
"People will still be able to manually tag friends, but we won't suggest you to be tagged if you do not have face recognition turned on," Narayanan said.
"If you already have the face recognition setting, you won't receive a notice."
The move comes amid growing concerns about facial recognition technology by law enforcement and government agencies, and with widespread use of the system for surveillance in parts of the world including China.
