Abstract:
The disclosed systems, and methods are directed to a method for Privacy Preserving Inference (PPI) comprising receiving a first set of matrix information from a client device, generating kc−1 matrices by operating a first CSPRNG associated with the server with kc−1 seeds, computing inferences from the set of kc matrices, generating a matrix Ss, generating ks−1 random matrices, computing a matrix Yks in accordance with the inference matrix Y, the matrix Ss and the ks−1 random matrices, transmitting a second set of matrix information to the client device, the second set of matrix information includes ks−1 seeds corresponding to the ks−1 random matrices and the matrix Yks, receiving a matrix U from the client device, and computing an inference value y from the matrix U.
