Abstract
Systems and methods of secure analytics using an encrypted analytics matrix are disclosed herein. An example method includes encoding an analytic parameter set using a homomorphic encryption scheme as a homomorphic analytic matrix, wherein the homomorphic analytic matrix is generated by extracting a set of term components from an analytic and the analytic parameter set using a term generator function; transmitting a processing set to a server system, the processing set including at least the homomorphic analytic matrix and a keyed hashing function; and receiving a homomorphic encrypted result from the server system, the server system having utilized the homomorphic encryption scheme and the keyed hashing function to evaluate the homomorphic analytic matrix over a datasource.
