Abstract: Provided are systems and methods for performing a secure machine learning analysis over an instance. An example method includes receiving, from a client, by a server in an environment, an encrypted machine learning data structure that is formed by using a homomorphic encryption scheme to encrypt a machine learning data structure. The machine learning data structure is generated by training a machine learning model that contains the data structure. The method includes extracting, by the server, a previously unseen instance of data. The method continues with evaluating, by the server, the encrypted machine learning data structure over the previously unseen instance of data using the machine learning model, to generate an encrypted result about the previously unseen instance of data. The method concludes with sending, from the server, the encrypted result to the client. The encrypted result is configured to be decrypted at the client using the homomorphic encryption scheme.
