Izitru lets you check whether photos are real or fake, for free

This should be a handy little tool for ATS to take advantage of!

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.

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.

Quite a few - alleged - 'Ghost Sighting' topics came to mind when I first read about this. It could be a very easy way to verify a topics imagery as unaltered.

Here's the link to the site itself!

Very cool whats available for us to use out there.
Is it able to work off of stills from film or would those signatures be out of it's scope?

Hmm, that's a good question! I would say that it would likely only be suitable for photographs, but I wouldn't be able to give any credible response.

Perhaps we should consider the proper use?

If we don't have the original picture straight of the camera, this site will be of no use.
As soon as a picture has been cropped and re-saved then it is of no use.
We can't use the site retrospect as it were, but only to validate our own pictures that we want to provide for everyones perusal.

And then we have the Terms & Conditions:

The facilities of Fourandsix and its business partners are located around the world. As a result, information provided to us by a user may be delivered to, and processed in, a country that mandates a lesser level of data protection than does the user’s home country.

I for one will retain my own rights and copyright as well as my personal data.

Well that's too bad... but i know ghost had good intentions so thank you anyway ghost.

By the way, I've flagged this thread because it has the potential to be very educational for a lot of people!

A seemingly great idea might be reduced to nothingness (or worse) by a few seemingly minor details...

The internet... it's a trip.
