The present disclosure provides a data processing method, an electronic device and a computer-readable storage medium. The method includes: acquiring first image data of images stored in a local device and second image data of images stored in another device; comparing the first image data with the second image data to determine a storage type of an image contained in the first image data and/or contained in the second image data; establishing a mapping relation between a first face group contained in the first image data and a second face group contained in the second image data according to the storage type; and processing the first image data and the second image data for the first face group and the second face group having the mapping relation with each other.
