What is it? TinEye is a reverse image search service which allows users to look up various instances of an image in question. Determining prior occurrences of an image is one way to reveal if the image is being used in a factual context.
How to use it to verify information: After uploading an image or its URL, TinEye will gather all the exact duplicates of the image. This allows the user to verify the exact date and time the image was first published as well as to review the various contexts in which it has been published in order to determine if an image is being used inaccurately/in the wrong context.
