You mean in the general case, for an image obtained from an unknown
camera?

Because if you only want to do it for your own camera(s), you can do
what the Wikipedia article describes, and use a calibration image to
determine the sensor “fingerprint”, so you can subtract that from all
images you intend to publish.
