1. A processor-implemented method for training an analysis model, the method comprising:
receiving synthetic data for original data from a client apparatus;
determining a data preprocessing scheme to be applied to the original data for analysis model training using the synthetic data;
determining a hyperparameter value for training analysis model using the synthetic data;
receiving a ciphertext for the original data from the client apparatus; and
training the analysis model using the determined hyperparameter value and the received ciphertext.
