Is it a fake or a real picture? Graphic software & the artists involved are so good now, that it has become extremely difficult for the human eye to tell the difference between the original photo and the one that’s been doctored.
“The software, called FourMatch, analyzes the meta data in picture files to quickly determine if a photo has been modified. FourMatch relies on a comprehensive database of more than 70,000 “signatures” that are left on a file from each piece of hardware and software that goes into creating it. As the company explains in a description of the product, “Once an image has been edited and re-saved from a software product, this signature is changed to match the software rather than the original capture device.”
FourMatch is primarily intended for police and lawyers who need to determine whether a photograph has been tampered with in any way between the time it was first captured and submitted as evidence. However, the software won’t tell you exactly how the image has been altered — if it has been at all — because it only analyzes the file data rather than the image itself. For this reason, it can just tell you if a file has been touched by another application”.
“This first product we’ve put out is not a magic bullet that will tell you everything you need to know about an image,” Kevin Connor, the company’s president and co-founder who worked at Adobe for 15 years, said. “This is sort of a first step and there are certain scenarios when it will be very valuable, particularly in the law enforcement space.” Indeed, the software currently retails for $890 so it’s clearly not intended for the average consumer”.
You can validate photographic evidence
Silence questions by producing compelling evidence that images remain exactly as they were captured by the camera.
It’s possible to assess reliability of social media images
Before taking action, gain a deeper understanding of the possible provenance of images found on the web.
Flag suspicious photo submissions
By instituting a controlled workflow that requires the submission of pristine camera originals, you can easily flag images that require closer scrutiny.
