"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."

Moderate changes to an image will probably still allow the technique to be used. Some cropping, moderate levels or curves adjustment, moderate sharpening all would probably be possible to work around.
More severe edits would certainly be problematic. I'd venture a guess to say the vast majority of photos taken are never edited at all, or at most have very basic editing done.

| It doesn't matter, if you printed the picture at home you already have a unseen "fingerprint" left by the printer that the FBI can analyse anyway... |

| Simple way to get around any trouble. Don't take any shots that can get you into trouble. |
