izitru, An Image Hosting Website for Authenticating Photos

izitru is an image hosting website by image analysis and forensics company Fourandsix Technologies that allows users to upload images that are put through rigorous automated tests in order to authenticate them and prove they are what they say they are. Each image is assigned a trust rating, and more controversial images can be challenged in order to have humans attempt to certify it.
