"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," the company said.
Google Glass, which is still under development, uses a voice interface to allow users to take pictures, send messages, look up directions or access the Internet.
Rep. Joe Barton (R-Texas) and seven other House members sent a letter to Google last month asking a series of questions about privacy protection policies for Glass.
"Is it true that this product would be able to use Facial Recognition Technology to unveil personal information about whomever and even inanimate objects that the user is viewing," the lawmakers asked. "Would a user be able to request such information? Can a non-user or human subject opt out of this collection of personal data?"
