WASHINGTON (AP) -- Google says it's improved the encryption technology for its flagship email service.
The change will make it harder for the National Security Agency to intercept messages moving among the company's worldwide data centers.
Among the most extraordinary disclosures in documents leaked by former NSA systems analyst Edward Snowden were reports that the NSA had secretly tapped into the main communications links that connect Yahoo and Google data centers around the world.
Google has previously said it was outraged over the practice. It didn't mention the NSA in Thursday's announcement, except in a veiled reference to what it called "last summer's revelations."
