Imagine the situation: you are trying to post to social networks is quite a harmless photo with corporate parties (bachelor, fishing etc). And after a while someone armed with new technology, processes reflected in your pupil, and there ... everything that was happening at this time on the other side of the camera, and perhaps not meant for the public eye.
This is not fantasy, it's true: Modern technologies allow to find out what (or whom) you were looking at a moment when you photographed, and therefore, in whose company were and perhaps even what they do. For some it can be a great help and an alibi to prove his innocence, and someone can seriously get stuck due to inadvertently lined long ago shot.
It is known, for example, many cases where criminals photographed hostages for whom hope to get a ransom or perverts shoot their victims "in memory". Now pictures can help uncover such crimes. In addition, pupils are sometimes victims are recognized and details of the situation in which you can set her whereabouts.
Of course, the image reflected in the pupils of persons to be not too crisp. However, even in these images, as shown by an experiment conducted by specialists of the School of Psychology at the University of Glasgow, allows us to identify the individual with an accuracy of about 90 percent.
Judge for yourself: you should be able to recognize that someone you know well, despite the fact that this image is only 16 × 20 pixels
And, last but not least the advent of this technology have an opportunity to review the archives and find answers to old mysteries
