Mayo Clinic investigators said facial recognition software could be used to match photos of people to facial reconstructions derived from magnetic resonance imaging (MRI) scans of their heads. The University of Pennsylvania's Aaron Roth warned this technique eventually will be used to compromise stored medical data. The University of California, San Francisco's Michael Weiner said the Mayo Clinic's findings represent a threat to privacy, citing the Alzheimer's Disease Neuroimaging Initiative as a potential target. The Initiative has MRI brain scans that include participants' faces, with identifying data removed; Weiner suggested attackers could match those MRIs to images of study subjects elsewhere .... "
