A rare photo, released by the White House, shows Barack Obama fielding calls from a tent in Brazil, to keep up with events in Libya. The tent is a mobile secure area known as a Sensitive Compartmented Information Facility, designed to allow officials to have top secret discussions on the move.

They are one of the safest places in the world to have a conversation.

Designed to withstand eavesdropping, phone tapping and computer hacking, Sensitive Compartmented Information Facilities - also known as SCIFs - are protected areas where classified conversations can be held.

Increasing use of computers and networks in business, government, recreation, and almost all aspects of daily life has led to a proliferation of online sensitive data, i.e., data that, if used improperly, can harm the data subjects. As a result, concern about the ownership, control, privacy, and accuracy of these data has become a top priority. This project focuses on both the technical challenges of handling sensitive data and the policy and legal issues facing data subjects, data owners, and data users.

The PORTIA goals are (1) to design and develop a next generation of technology for handling sensitive information that is qualitatively better than the current generation's and (2) to create an effective conceptual framework for policy making and philosophical inquiry into the rights and responsibilities of data subjects, data owners, and data users.

Response by Jack Dorsey to Verifone's accusation that Square readers are insecure: "Today one of our competitors alleged that the Square card reader is insecure. This is not a fair or accurate claim and it overlooks all of the protections already built into your credit card. Any technology—an encrypted card reader, phone camera, or plain old pen and paper—can be used to “skim” or copy numbers from a credit card. The waiter you hand your credit card to at a restaurant, for example, could easily steal your card details if he wanted to—no technology required. If you provide your credit card to someone who intends to steal from you, they already have everything they need: the information on the front of your card."
