Abstract: 

The Jana project develops tools, methods, and systems for secure and private data access. Jana provides a practical implementation of private data-as-a-service that gives data users efficient query access to data without a priori obfuscation or de-personalization; gives data subjects peace of mind by allowing them to choose which data to contribute and when it may be used, and keeping that contributed data encrypted at all times, starting before it leaves their possession; provides practical speed, reliability, and usability at scale that supports data from a few million data subjects and concurrent query access by tens to hundreds of data users; limits results of data user queries to what data subjects are willing to reveal, as determined by policies they specify; and allows data subjects to be informed (and their policy engines to learn and adapt) when their data is used.
