Abstract: A method of determining a geofence based on user locations belongs to the field of computer technologies. The method of determining a geofence based on user locations includes: obtaining user locations in a plurality of pieces of user data; aggregating the user locations according to similarities in latitude and longitude coordinates of the user locations, to determine aggregation points and a central aggregation point; denoising the aggregation points according to distances between the aggregation points and the central aggregation point; and sorting, according to values of longitude coordinates or latitude coordinates, aggregation points obtained after the denoising, to determine geofence boundary data in a preset format.
