Today eight members of the U.S. Congress have sent a letter to Google's Larry Page, asking him to address a number of privacy concerns about Google Glass. In the letter (PDF), they brought up the company's notorious Street View data collection incident, and asked how the company was planning to avoid a similar privacy breach with Glass. They also ask how Google is going to build Glass to protect the privacy of non-users who may not want their every public move to be recorded. Further, they ask about the security of recordings once they are made: "Will Google Glass have the capacity to store any data on the device itself? If so, will Google Glass implement some sort of user authentication system to safeguard stored data? If not, why not?" Google has until July 14th to respond.
