Programmable data processing method and system based on trusted execution environment

The embodiment of the invention provides a programmable data processing method and system based on a trusted execution environment, and the method comprises the steps: responding to a task execution request sent by a task initiator, creating a virtual container corresponding to the task execution request, and enabling the virtual container to belong to the trusted execution environment; determining at least one data provider according to the task execution request, obtaining a sample data set corresponding to the at least one data provider, and loading the sample data set to a virtual container; receiving model processing information sent by the task initiator, and determining an initial task model and a model training strategy corresponding to the initial task model based on the model processing information through the virtual container loading the sample data set; and training the initial task model in the virtual container loading the sample data set according to a model training strategy, and feeding back
