A critically important component of most signal processing procedures is that of computing the distance between signals. In multiparty processing applications where these signals belong to different parties, this introduces privacy challenges. The signals may themselves be private, and the parties to the computation may not be willing to expose them. Solutions proposed to the problem in the literature generally invoke homomorphic encryption schemes, secure multi-party computation, or other… CONTINUE READING
