Privacy - Preserving Multi-Party Conditional Random Selection
Stefan Wüller, Benjamin Assadsolimani, Ulrike Meyer, Fabian Förg, Susanne Wetzel · 2019
The primitive of conditional random selection allows the selection of a data record uniformly at random from the subset of data records that meet a specified condition. In this paper, we extend a previously introduced privacy-preserving two-party protocol (that implements this primitive in the context of passive adversaries) to the multi-party case. Additionally, we provide a comprehensive performance analysis of the newly designed protocol and discuss application scenarios.
