Data processing method and device, data synchronization processing method and device and electronic equipment

The embodiment of the invention discloses a data processing method, a data synchronization processing method, a data synchronization processing device and electronic equipment. A specific embodiment of the method comprises the following steps: in response to a received opposite-side data source authorization instruction, obtaining an opposite-side feature data set; fusing the opposite side feature data set and a local original data set into a to-be-processed data set; calling a program interface corresponding to the to-be-processed data set to generate a data feature value set corresponding to each piece of to-be-processed data in the to-be-processed data set; and based on the data feature value set, performing screening processing on the to-be-processed data set to obtain a processed feature data set. The implementation mode is related to federal learning, and the data processing efficiency can be improved. 本公开的实施例公开了数据处理方法、数据同步处理方法、装置和电子设备。该方法的一具体实施方式包括：响应于接收到对侧数据源授权指令，获取对侧特征数据集；将上述对侧特征数据集与本地原始数据集融合为待处理数据集；
