Zusammenfassung:	Implementations this specification provide a method and an apparatus for determining data processing model parameters through multiparty cooperation. An example method performed by a data party device includes secretly sharing a first product with a cooperation partner device, based on characteristic data and a share of an original model parameter; communicating with the cooperation partner device, based on the share of the first product and a garbled circuit corresponding to an activation function, to obtain a share of a value of the activation function; secretly sharing a gradient of a loss function with the cooperation partner device, based on the characteristic data and the share of the value of the activation function, to obtain a share of the gradient of the loss function; and computing a share of a new model parameter.
