Back in October, the startup tech firm Silent Circle ruffled governments' feathers with a surveillance-proof smartphone app to allow people to make secure phone calls and send texts easily. Now, the company is pushing things even further—with a groundbreaking encrypted data transfer app that will enable people to send files securely from a smartphone or tablet at the touch of a button. (For now, it's just being released for iPhones and iPads, though Android versions should come soon.) That means photographs, videos, spreadsheets, you name it—sent scrambled from one person to another in a matter of seconds.
