Abstract

A method for performing secure computations on records, comprising: receiving a request to apply a computation on a record; assigning a respective partial record of a plurality of partial records of the record to each of a plurality of computational processes; instructing each of the plurality of computational processes to perform a computation scheme comprising: applying a semi honest multiparty computation on the partial record; iteratively repeating a predetermined number of times: using a secure multiparty arithmetic computation to generate random terms; using the secure multiparty arithmetic computation to assign the random terms and an outcome of the application to at least one predetermined equation; verifying an integrity of the semi honest multiparty computation by comparison of the assignments to the at least one predetermined equation to at least one constant; and when the integrity is valid, combining the applications of the semi honest multiparty computations on the partial records.
