From the DARPA website—DARPA “BRANDEIS” PROGRAM AIMS TO ENSURE ONLINE PRIVACY

DARPA announced plans on March 11, 2015 to research and develop tools for online privacy, one of the most vexing problems facing the connected world as devices and data proliferate beyond a capacity to be managed responsibly. Named for former Supreme Court Justice Louis Brandeis, who while a student at Harvard law school co-developed the concept of a “right to privacy”…The goal of DARPA’s newly launched Brandeis program is to enable information systems that would allow individuals, enterprises and U.S. government agencies to keep personal and/or proprietary information private.

Existing methods for protecting private information fall broadly into two categories: filtering the release of data at the source, or trusting the user of the data to provide diligent protection. Filtering data at the source, such as by removing a person’s name or identity from a data set or record, is increasingly inadequate because of improvements in algorithms that can cross-correlate redacted data with public information to re-identify the individual. According to research conducted by Dr. Latanya Sweeney at Carnegie Mellon University, birthdate, zip code and gender are sufficient to identify 87% of Americans by name.

On the other side of the equation, trusting an aggregator and other data recipients to diligently protect their store of data is also difficult. In the past few months alone, as many as 80 million social security numbers were stolen from a health insurer, terabytes of sensitive corporate data (including personnel records) were exfiltrated from a major movie studio and many personal images were illegitimately downloaded from cloud services.

“Currently, most consumers do not have effective mechanisms to protect their own data, and the people with whom we share data are often not effective at providing adequate protection,,”

Currently, we do not have effective mechanisms to protect data ourselves, and the people with whom we share data are often not effective at providing adequate protection.The vision of the Brandeis program is to break the tension between (a) maintaining privacy and (b) being able to tap into the huge value of data. Rather than having to balance between them, Brandeis aims to build a third option, enabling safe and predictable sharing of data in which privacy is preserved. Specifically, Brandeis will develop tools and techniques that enable us to build systems in which private data may be used only for its intended purpose and no other. The potential for impact is dramatic. Assured data privacy can open the doors to personal medicine (leveraging cross-linked genotype/phenotype data), effective smart cities (where buildings, energy use, and traffic controls are all optimized minute by minute), detailed global data (where every car is gathering data on the environment, weather, emergency situations, etc.), and fine grained internet awareness (where every company and device shares network and cyber-attack data). Without strong privacy controls, every one of these possibilities would face systematic opposition [it should].
