It isn't just privacy that is at risk in this new era of Big Data collection. Secrecy is a casualty too. It used to be classified documents were kept in a safe and seen by a select view. Now a top secret document can be accessed by hundreds, if not thousands, all with the click of a mouse. Because of that the modalities of spying have changed. Now analysts can take an infinite number of secrets with them by just putting them on a thumb drive, but it's a counter-intelligence nightmare.
