Fake News: Die erfolgreichsten Fake News: Wir zeigen Ihnen was hinter den bekanntesten Falschnachrichten steckt

# data[].attributes.attachment_link.description
Vor Fake News ist man mittlerweile fast nirgends mehr sicher. Auch Papst Franziskus, Grünen-Politikerin Renate Künast und Schauspieler Morgan Freeman wurden schon für Falschnachrichten missbraucht. Wir stellen die bekanntesten Falschnachrichten vor und erläutern die Hintergründe.

Computers have long made it possible to create highly realistic fake images. Now, thanks to Izitru - a new service launched by photo forensics firm Fourandsix - those very same computers can help us automatically detect those fakes. Izitru builds on the pioneering work that imaging guru Hany Farid has done in detecting phony photos. Unlike previous systems, Izitru is completely automated, relying on a set of six tests to help verify uploaded JPEG images.

How Izitru works

Izitru (pronounced "is it true") builds on the JPEG signature analysis first launched in Fourandsix's FourMatch plug-in for Photoshop. This test uses the fact that nearly every model of digital camera uses slightly different coefficients for doing the encoding and compression of its JPEG images. Photoshop uses a different, but consistent, set. Using its database of camera models and their coefficients - aka signatures - Izitru can verify what camera is most likely to have created the image.

Of course, now that JPEG signature analysis is a known technology, it can be spoofed with some work, so Izitru runs other tests. One test looks for signs that the JPEG has been saved more than once (perhaps with the second save designed to fake a camera signature). Another is designed to look at the structure of the JPEG encoding to determine if it is likely to have come from camera firmware or from computer software.

Final tests look to see evidence of the camera's original Bayer sensor pattern, and also whether the image may have been saved at multiple quality settings - called JPEG ghost detection. The ghost detection works by re-saving the image at a variety of quality settings and looking to see which ones are most similar to the suspect image. There will be an expected dip in the graph of differences at the quality setting used in creating the suspect image, but there may also be other dips - evidence that the image was originally saved at a different quality setting.

In my testing of the service it accurately rated as "high trust" all the camera originals I fed to it (for new camera models, images show up as "medium trust" until Fourandsix adds their JPEG signatures to its database). Basic captioning (modifying the image's metadata) doesn't affect that rating - as long as the image editor you use to do the captioning keeps the original JPEG header and image data intact.

There are limits to Izitru's automated capability. Unlike the more sophisticated, manual, tests that Farid is famous for, the automated tests don't detect particular manipulations. Instead they are designed to determine whether a JPEG image is unmodified. Fourandsix provides an iOS app for directly uploading images from your Apple mobile device to its service. That's important because Apple's iOS browser re-saves images and strips metadata before uploading, so they can't be verified unless the custom app is used.

Sharing and challenge system

Izitru lets you share your image and its trust rating by providing you with a link to a hosted version on its site. This isn't just a static link, though. If an image is in dispute, it can be challenged by anyone looking at the link. Image forensic specialists at Fourandsix will run additional, manual, tests on images that receive a high number of challenges - hopefully settling the issue once and for all. While it wouldn't have avoided controversies like the one over the World Press Photo competition winner, it should help settle plenty of disputes.

Raw files: The gold standard for image authenticity

As good as image forensic tools are, one of the best ways to prove an image is original is by being able to provide the raw file from which it is rendered. While it is not completely impossible to artificially create a raw image file, there aren't any commercially available tools that can create one, and the imaging math required to make one plausible is well beyond the reach of most would-be forgers. Some photo contests now require that images in the final judging stages be accompanied by the original Raw file.

Commercial uses

While Izitru will certainly get used for lots of bet settling between friends, its applications go well beyond casual use. The site itself, including image ratings and hosting, is free, but Fourandsix is looking forward to a variety of profitable commercial applications. Insurance companies needing to verify accident photos and online buyers needing to verify the authenticity of product shots are only two of the many possible use cases. To facilitate these applications, Fourandsix is making an API available for direct integration to its service.
