First vector and a method for obtaining the result of applying the function to the second vector, and the third first vector and a second system for determining the results of applying the function to the vector of using a processor
PROBLEM TO BE SOLVED: To provide a computational system in which multiple parties jointly compute a certain value based on individually held secret information, without revealing the information to any of the other parties.;SOLUTION: One embodiment of the present invention is a system and a method for determining a result of a function applied to a first vector 115 and a second vector 116, in which the function is a normalized sum-type function. The first vector is stored at a first processor 117, and the second vector is stored at a second processor 118. The system and the method determine a joint empirical probability distribution (JEPD) of the first vector and the second vector using a secure multi-party computation. The function is determined as a normalized summation of products of values of the JEPD with corresponding values of the function.;COPYRIGHT: (C)2012,JPO&INPIT
