"Because Google Glass has not yet been released and we are uncertain of Google's plans to incorporate privacy protections into the device, there are still a number of unanswered questions that we share," the Bi-Partisan Privacy Caucus, led by Rep. Joe Barton (R-Texas) wrote in a letter to Google CEO Larry Page.
Eight members of Congress signed the letter, and they want information from Google by June 14. They cited specific examples of privacy issues in Google's history to support the concerns about privacy.
Google Glass has received a lot of buzz, but its capabilities largely are limited at this point. Still, privacy and security are two of the major concerns for Google Glass, and at least one bar has. Users could seemingly videotape or photograph others without their knowledge, and it's unclear what provisions are in place to protect users' information, particularly as more developers create apps for the computing eyewear.
