Google said it will not add facial recognition features to its products until the issues of privacy protections are resolved.
Google said: "When we started the Explorer Program nearly a year ago our goal was simple: we wanted to make people active participants in shaping the future of this technology ahead of a broader consumer launch."
"We’ve been listening closely to you, and many have expressed both interest and concern around the possibilities of facial recognition in Glass," the company said.
"As Google has said for several years, we won’t add facial recognition features to our products without having strong privacy protections in place. With that in mind, we won’t be approving any facial recognition Glassware at this time."
Google Glass is an Android powered, internet-connected device similar to a smartphone that operates on voice commands.
The hands-free Google Glass can be used to capture pictures and record video, in addition to sharing content directly through email or social networks.
Last month, the US Congressional Privacy Caucus asked Google to explain how the company will protect the privacy of people after Google Glass hits the market.
