The last protocol is POSEIDON. The paper extends SPINDLE (Privacy-Preserving Training and Evaluation for Generalized Linear Models) by building a new system (named POSEIDON) that enables privacy-preserving training and evaluation of more complex neural network models in a distributed setting through multiparty HE, providing end-to-end protection: training data for all parties, the resulting model, and evaluation data for the querier. The weights of the neural network models are always encrypted during training and evaluation.
