Barton is founder and co-chairman of the Congressional Privacy Caucus, which sent a request to Google to elaborate on privacy implications for new technologies like Google Glass.

Molinari pointed to Google's recent decision to ban facial-recognition technology on Glass in the near future. She also noted that the device's camera cannot be used without the user's knowledge.
However, Barton does not think Google's response went far enough.
"I'm not anti-Google and I'm not anti-technology ... but I do think an individual still has a right to privacy in the 21st century," Barton said. "I think it's time to have a serious debate about it in the Congress with the developers. It doesn' t have to be antidevelopment, but we do need to agree that the individual's privacy is paramount, as opposed to the developer's ability to collect, disseminate and market."

Barton added that some companies, such as Microsoft have been "very cooperative" with privacy protection, while many companies and government agencies may not show similar restraint. "It's a big problem," he said.
