Google in a race vs the NSA to encrypt data

Google is racing to encrypt the torrents of information that flow among its data centers around the world in a bid to thwart snooping by the NSA and the intelligence agencies of foreign governments, company officials said Friday.

The move by Google is among the most concrete signs yet that recent revelations about theNational Security Agency’s sweeping surveillance efforts have provoked significant backlash within an American technology industry that U.S. government officials long courted as a potential partner in spying programs.
