Police Use DNA To Generate a Suspect's Face 100
The accuracy of these portraits is still an area of hot debate — most of them look rather generic. The NY Times staff tested it with a couple of their employees, circulating the DNA-inspired portraits and seeing if people could guess who it was supposed to be. None of the ~50 employees were able to identify reporter John Markoff, and only about 10 were able to identify video journalist Catherine Spangler. But even though the accuracy for a person's entire face is low, techniques for specific attributes, like eye color, have improved greatly. Of course, the whole situation raises a slew of civil liberties questions: "What traits are off limits? Should the authorities be able to test whether a suspect has a medical condition or is prone to violence should such testing be possible?"
