A new study published in PLOS ONE shows that the high resolution images produced by modern digital cameras can be used to identify the photographer and other individuals positioned behind the camera. The researchers, from the University of York (U.K.), say that images retrieved from subjects’ corneal reflections could be especially important when the images record criminal activity – such as hostage taking or child sex abuse.
The study also notes that in a test of spontaneous recognition, the observers could reliably name a familiar face (in this case Barack Obama) from an eye reflection image.
