Digital Cameras Leave Unique 'Fingerprints'

Will Knight writes on NewScientistTech:

A new forensic technique means many digital photographs can now be traced to the individual cameras that took them. The method works by analysing imperfections in the cameras' light sensors.

Jessica Fridrich and colleagues at Binghamton University in New York, US, analysed more than 3000 digital images taken using 11 different models of digital camera. They found that minute flaws in each camera's sensors left their mark on the images, making it possible to link each picture to a particular camera.
