The work centers around how to work with private data without exposing all the data. For example, how do we get data for medical research - such as the number of cases where both X and Y are found - from a number of hospitals without getting all the patient records? How can we store data in the cloud encrypted, and query it without giving away the keys to the whole data set? How can we prove a theory without showing the proof?
The work includes HElib to do computation on encrypted data and Functional Encryption for fuzzy identity based encryption (Sakai,Waters - 2005).
