The invention provides a privacy protection diagnosis method for a low-orbit satellite diagnosis model based on joint learning, and the method comprises the steps: collecting the medical diagnosis data of a target region; constructing a medical diagnosis model through a disease model server of a ground station, and transmitting the medical diagnosis model to a ground data collection point of the target region through a satellite network; according to the medical diagnosis data, training the medical diagnosis model to obtain model updating parameters; and performing encryption protection on the model updating parameters, and transmitting the encrypted model updating parameters back to the ground station through the satellite network. Through the method provided by the invention, a data privacy protection mechanism adaptive to a high-dynamic, low-power and complex topology environment of the satellite Internet of Things is designed, and the problems of data security collection and privacy model aggregation are
