SECURE MULTIPARTY DIFFERENTIALLY PRIVATE MEDIAN COMPUTATION

Abstract:

In an example embodiment, a differentially private function is computed via secure computation. Secure computation allows multiple parties to compute a function without learning details about the data. The differentially private function is performed via probability distribution, which then permits computation of a result that is likely to be very close to the actual value without being so exact that it can be used to deduce the underlying data itself.
