With the help of Dartmouth College, Reuters and Canon, Adobe will be developing a tool that will be able to distinguish the authenticity of a photo. It will come in the form of a Photoshop plugin and it can link a picture to a camera and even a specific camera. The plugin will also have the ability to track all of the changes made to a photo and even detect use of the clone stamp, a tool commonly used by photo manipulators. I'm just worried that they may find out the truth behind all of Jason's unpantsings.
