Technology has advanced to the point where research study participants can be identified by their MRI scans even after all other identifying information has been stripped, according to an experiment detailed yesterday in the New England Journal of Medicine and reported on by the New York Times.

Why it matters: If stored medical data were leaked, it could potentially be used to identify study participants for marketing, scams or even stalking.

The big picture,per the WSJ: These “results are the latest to find technology has outflanked privacy protections in health care, where an aggressive push is under way to amass and mine medical data from patient medical records, research, medical devices and consumer technology such as smartwatches.”

Details: An MRI includes a person’s entire head, and imaging technology is advanced enough to create a reconstruction of the face from the scan.
