Abstract
An example method for performing a secure probabilistic analytic includes acquiring, by a client, an analytic, at least one analytic parameter associated with the analytic, and an encryption scheme. The encryption scheme can include a public key for encryption and a private key for decryption. The method further includes generating, using the encryption scheme, at least one analytical vector based on the analytic and analytic parameter, and sending the analytical vector and the encryption scheme to at least one server. The method includes generating, by the server based on the encryption scheme, a set of terms from a data set, evaluating the analytical vector over the set of terms to obtain an encrypted result; estimating, by the server, a probabilistic error of the encrypted result; and sending, by the server, the encrypted result and the probabilistic error to the client where the encrypted result is decrypted.
