Digital cameras leave fingerprints behind - Scientists have found away to trace what camera was used to take a photograph.

NYU logoScientists can now work out which specific camera make and model a photo was taken on. Researchers at the Polytechnic University in Brooklyn, New York, have discovered that digital cameras leave a fingerprint in the pixels of every image taken. If this proves viable in further testing it could be used by forensic scientists in kidnap situations. Photos of the victim taken by the kidnapper could be traced back to the camera it was taken on and then this information could be used to find out where the camera was purchased and by who.

The system works as every digital camera has demosaicing software that translates each pixel into usable brightness and colours.  According to the research team the demosaicing software is made specifically for a particular camera type and the software algorithms are designed to work out what colour a particular screen pixel should be without clashing with the other neighbouring pixels colours.

Nasir Memon and his team have found a way to work backwards through theses neighbouring pixel values to discover which model-specific algorithm made it.

Early tests have show the technique can identify cameras with a 90% accuracy and further tests are to be carried out to collect more data.

You would have thought looking at the EXIF would be easier!!! I bet your average kidnapper doesn't know that EXIF even exists.

Now if it was like a fingerprint of an actual camera (which is suggested), rather than a make and model then I might be more impressed!

Kidnappers, in the scale of things, aren't that common, but if it could be used in cases of disputed copyright infringement, that's a different kettle of fish!

And why make it public?

Surely now kidnappers are aware, they can now try to work out some way of combatting it; they're not all thick....

Bang on Kris. Once again, 'The Authorities' shoot themselves in the foot.

And this method is useless if the image was shot in RAW and demoasic'd on a computer!!
