[WHOA...] Is That Picture Real?
Social media of all kinds - Facebook, Twitter, Instagram, etc. - are rife with disinformation spread by people with ulterior motives. It’s a huge problem; you never know if what you’re looking at is real or fake. Many users react emotionally to provocative fake photos and posts, sharing and commenting on them, perpetuating the false impressions and outright lies.
Verifying Authenticity Of Photos
In a recent study, I read that lots of people pass along these bogus items on social media without bothering to venture beyond the photo or the headline. You don’t want to be one of those people, right?
Doctored photos are a favorite tool of propagandists. There are many free photo editing tools online, making it dead simple to alter or create a fake photo. As an example of this sort of disinformation campaign, we can turn to the Charlie Hebdo massacre in France, January, 2015.
Almost immediately after news of the attack on Charlie Hebdo’s HQ broke, dozens of fake images and false comments on them flooded every social media outlet. The message was always the same: “They are lying to you.” The intent was to sow FUD - fear, uncertainty, and doubt - about legitimate news reports, and to blame “the Jews,” “the Freemasons,” “the Illuminati,” or some other mysterious group that “really runs the world.”
And then there are the hoaxsters, who create outlandish images by using photo editing tools such as Photoshop. The "Giant Squid on Santa Monica Beach" photo is one such example. The Gallery of Fake Viral Images has many more examples of doctored and misrepresented photos that have been passed along by lazy or unthinking people. (See also the Field Guide to Fake News Sites and Hoax Purveyors from Snopes.)
You don’t want to be one of those people, and you don’t want to be their unwitting tool by falling for and spreading their manure.
Unfortunately, a lot of people fall for it and spread it even further. If they had the knowledge and had taken the time, they could have discerned that the photos they shared were entirely bogus. Here is how you can do it, and avoid being a pawn of hoaxsters and propagandists.
How to Identify Fake Photos
Step 1: When was the photo taken? Doctoring a real photo of a tragedy is a complicated and time-consuming process. It’s much simpler to take an older photo out of context and link it to a news story about the tragedy. If you can determine that an image was made before a tragedy, but it claims to depict the actual event, you can be sure it’s fake.
One way to check a photo’s age is to look for prior use of it. Google's reverse image search feature will find matches and near-matches to virtually any suspect image. If you use the Chrome browser, the simplest way to perform a reverse image search is to right-click the image you see on a website, and then click "Search Google for this image." You can also search using the image URL, or drag and drop the image. See the reverse image search help page for instructions.
TinEye.com is a dedicated reverse-lookup image index. Just right-click on the suspect image, select “copy image address,” and paste that address into the search box at TinEye. If you find a suspect image in a context that puts it clearly before the date of the real event, consider it fraudulent.
Videos are misrepresented in the same way, and can have even more powerful disinformation effects because video is more “credible” than still imagery. There is no reverse-lookup site for videos; the technical challenges are greater. Amnesty International has partnered with YouTube to create a YouTube DataViewer but its limitations make it unreliable.
First, it only covers videos uploaded to YouTube; contrary to appearances, that does not include every video ever made. Second, if a video is edited in any way, even by trimming off a few seconds, its metadata will no longer match the original and it won’t be found in a DataViewer search.
Take a Look Under the Hood
Perhaps the most reliable information about a photo is stored in the photo itself. Called EXIF Image Data, this hidden text includes such valuable information as when a photo was taken; what kind of camera took it; and even the geolocation coordinates if it was taken with a smartphone that had “location services” enabled. You can right-click on the photo and click "Properties", then "Advanced", to take a look at the EXIF data. Jeffrey Freidl’s Image Metadata Viewer can even pin a photo to a map, if it includes geolocation data.
If you find that a heartbreaking photo of a little girl covered in mud and holding an equally sad puppy was actually taken in Australia, you can be sure it is not a photo of a Bosnian war orphan. EXIF data can be altered to deceive, but most of the people who spread disinformation this way are not that technically savvy. You will catch a lot of fake images by looking at EXIF data.
Also, consider the source of an image. If someone in New Jersey is feverishly posting outrage-inducing photos “in real time” of an incident taking place in Germany, it just doesn’t make any sense. As Judge Judy loves to say, “If it doesn’t make sense it probably isn’t true.”
Twitter’s Advanced Search enables you to rule out such frauds by restricting searches to the location where you know the event is or has occurred. Facebook can also tell you the location of a user.
Bottom line, don't believe everything you see online. You can avoid looking foolish, or playing into the hands of ill-intentioned scoundrels by doing a few seconds of research before passing along a photo or story.
