Your digital photos can be traced

Virtually all modern electronics leaves a trail. Just walking around town with a cell phone allows your movement to be tracked.

Here's a story that shows how even photos now leave an electronic ghost behind.

Scientists 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.
