Secure Analytics Using Homomorphic and Injective Format-Preserving Encryption and an Encrypted Analytics Matrix

摘要

Systems and methods that provide secure analytics using homomorphic and injective format-preserving encryption and 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; 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, the keyed hashing function, and a format preserving encryption scheme to evaluate the homomorphic analytic matrix over a datasource.
