Secure analytics using homomorphic and injective format-preserving encryption and an encrypted analytics matrix

A method, comprising:

• receiving a homomorphic analytic matrix that comprises an analytic and analytic parameter set encoded by a client system using a homomorphic encryption scheme;
• utilizing at least the homomorphic encryption scheme, a keyed hashing function, and a format preserving encryption scheme to evaluate the homomorphic analytic matrix over a datasource and generate a homomorphic encrypted result;
• and
• transmitting the homomorphic encrypted result to the client system.

A system comprising:

• a client system configured to:
• encode an analytic parameter set using a homomorphic encryption
• scheme as a homomorphic analytic matrix;
• transmit a processing set to a server system, the processing set comprising
• at least the homomorphic analytic matrix and a keyed hashing function;
• and
• receive a homomorphic encrypted result;
• and
• a server system that communicatively couples with the client system and a data repository, the server system being configured to:
• receive the processing set from the client system;
• utilize at least the homomorphic encryption scheme, a keyed hashing function, and a format preserving encryption scheme to evaluate the homomorphic analytic matrix over a datasource and generate a homomorphic encrypted result;
• and
• transmit the homomorphic encrypted result to the client system.
