In a Google Plus remark, Google said that it would block all facial recognition apps from Google Glasses
Glass and Facial Recognition
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. 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.
#IfIHadGlass winners are expected to begin receiving their Glass prototypes over the coming weeks. Clearly, this move is to help the new wave of non-developers get along in a skeptical world.
