Private Private Information With Kevin He and Fedor Sandomirskiy
Omer Tamuz, Professor, Department of Economics, Caltech,

A private private information structure delivers information about an unknown state while preserving privacy: a signal contains information about the state but remains independent of sensitive or private information. For example, we might want to design a recommendation system that delivers information about an applicant's fit for a position, while not revealing anything about a protected characteristic. We study how informative such structures can be and characterize those that are optimal in the sense that they cannot be made more informative without violating privacy.
