izitru article on gigaom.
izitru website.
"The real potential of izitru may be in verifying photos on online dating or citizen journalism sites that adopt the API."
Does this mean we can eliminate site council for verification of originals? Probably not since it is jpeg only it appears. But what a concept if it would/could accept raw images and you could implement it in a way to print a report on an image to include as part of a description perhaps in a portfolio. Like a stand alone version of the web version. I don't have the programming skills to do anything with the API.
"The izitru developer API makes it easy to add photo authentication to any website or app, or to integrate authentication into an enterprise content management system or file submission process. The API can provide detailed information about the results of each of izitru's six forensic tests, so you have the flexibility of deciding your own criteria for photo approval."

Tried a couple images, and found that an image shot in RAW and converted will never pass their test. The one thing they cannot detect is a photo of a photo, so that really is the "open door" to gaming their system.
Their forensic tests seem to rely on both the structure of the file and the JPEG compression settings. It gave me a "high trust" rating for a native 6D Large/Fine JPEG, but rejected a 6D image shot in RAW, converted in Lr and exported from Lr. this is because they are looking at the JPEG compression characteristics, or "fingerprint" if you will for that camera model, and the JPEG did not come from the camera.
ETA:
Interestingly, I also earned a "high trust" result with an out-of-camera JPEG using the camera's Small/Low Quality JPEG setting, resulting in a 5Mpx file only 599KB in size. So their algorithms are sophisticated enough to know that a given camera might produce a range of outputs.
