In a feature straight out of the movies, Dr. Rob Jenkins and his team have demonstrated that for sufficiently high-resolution photos, recognizable images of reflected faces of the photographer and bystanders can be retrieved from a subject’s eyes.
The researchers say that in crimes in which the victims are photographed, such as hostage taking or child sex abuse, reflections in the eyes of the photographic subject could help to identify perpetrators. Images of people retrieved from cameras seized as evidence during criminal investigations could be used to piece together networks of associates or to link individuals to particular locations.
By zooming in on high-resolution passport-style photographs, Jenkins and co-researcher Christie Kerr of the School of Psychology, University of Glasgow were able to recover bystander images that could be identified accurately by observers, despite their low resolution.
Here’s some older research about reading confidential data using reflections from tea pots, glasses, eyes, and even diffuse materials like fabric. And of course, there’s the famous eBay tea kettle. (via waxy)
