The recent scandal over Facebook's use of personal information has shone fresh light on one of the most pressing issues of the 21st century:  How can we protect our privacy when we are willingly—or unwillingly—giving vast amounts of data to companies like Facebook, Google, or Amazon. But those technology companies aren’t the only ones using personal information. This kind of data is also at the core of the work of international agencies delivering humanitarian aid. In this week's episode we speak with Dan Scarnecchia, a researcher with the Signal Program on Human Security and Technology based at the Harvard Humanitarian Initiative. Scarnecchia and his colleagues recently wrote the Signal Code, which represents a human rights approach to privacy and data during crises. We'll examine how the humanitarian field is now grappling with ever-changing technology and increasing reliance on data and personal information.
