The response has left a US congress committee, which demanded clarification over some Google Glass privacy concerns, pretty ticked off.
The response was sent from Google to the Congressional Bi-Partisan Privacy Caucus on June 7, and made it loud and clear that the company wasn't willing to compromise.
- Time to be concerned about Google Glass?
The European view
Jim Killock, executive director of the UK's Open Rights Group, told TechRadar that Europe has just as much, if not even more, reason to be discussing the problems surrounding Google Glass right now.
"They should be careful," he said. "They need to be aware that privacy and data protect in Europe is more stringent."
"The data is not necessarily about one individual, it may relate to other people. Then add to that this data is then being submitted to Google," said Killock, adding that the centralisation of the data is a big concern.
The fact that this is all taking place at the same time as the Prism scandal isn't doing Google any favours either, he said.
"If facial recognition technology is applied to data collected by Google Glass, it suddenly becomes a highly intrusive CCTV that could potentially be accessed by the US government."
As Killock highlighted, the biggest worry is the fact that Prism is targeted at non-US citizens under suspicion. "When it comes to non-US citizens, they could use [Google Glass] to access anything".
