Using Forensic Software to Spot Fake Photos

I wasn't sure where to post this article, but I thought that it might be of interest to a few OCC members.


Excerpt


Try reverse image searching


A reverse image search in Google looks for images that are exact matches, as well as those that are thematically similar.


Before you start trying to CSI an image too hard, you can often debunk a faked photo by finding its source using a reverse image search. Google includes this function as part of its Images suite and looks for the exact image, as well as images that are similar in both subject matter and color aesthetics.


Another powerful tool is Tineye, which performs a similar function, but often returns fewer results that are closer to exact matches, which can make them easier to sort through.


“Often if you just do a reverse image search, you’ll find it right away,” says [Hany Farid, a professor of computer science at Dartmouth College who specializes in photo forensics]. “You’ll see the original image that someone took from Getty Images and then added a UFO to the sky or something like that.”


Reverse image search can also be a useful tool if you suspect someone is stealing your social media photos and impersonating you. Upload your own photos to the tools and you can see where they appear on the web.
