Forensically is a web-based tool that can analyze whether a photo has been edited in any way. It's built to use only your browser and doesn't require you to upload anything online.
Created by Jonas Wagner, this amazing tool Forensically able to see if someone has “photoshopped” the regular photo and made changes to present their work as a “professional” photo, or if the photo they uploaded to the Ashley Madison website has been modified to make the person appear more attractive.
Dubbed photo forensics software, Forensically comes with a wealth of tools to help you find the areas of the image where someone has made modifications to the original.
The first tool is a magnifier that magnifies the pixels of the photo and their contrast. This tool is ideal for high-resolution images, where the smallest specks of dust found in the camera lens can be explored.
As Mr. Wagner stated, “With these powder specs, one could match an image to a specific camera based on the lens configuration, just as bullets can be matched to a gun based on the ballistic engravings from the gun barrel.”
The second tool is Clone Detection, which was developed specifically to detect the “clone tools” of various photo editing software, such as the tools someone uses to copy one part of an image to another part of the same photo. If you use Photoshop, you will know exactly what we are referring to and what this feature does.
The third tool included in forensically is an Error Level Analysis system that can detect when an image has been compressed multiple times in a row, a process that usually occurs when the image is altered. Forensically highlights these areas, such as those that are too light or too dark, compared to similar areas in the same image.
Forensically’s fourth tool is called Noise Analysis and can be used “to detect image manipulations such as airbrushing, distortion, warping, and cloning for perspective correction.” As Jonas Wagner specifically states, this tool “works best on high-quality images.”
The fifth tool included in the package is a simple metadata viewer (metadata or tags viewer), which can easily reveal information about the last editing date and the software used to do this editing, only of course in case the person who did the editing had no idea about metadata and how it is stored in each image and thus did not remove it from the photo's header.
If a photo also contains geolocation data, the Geo Tags tool will extract this data from the meta tags and display it on a map.
But these two tools rely on data stored in the caption of each image, which can be edited by anyone with the appropriate tools, and so the information in the captions is generally considered unreliable.
Last but not least, there is also the Thumbnail Analysis tool.
Since most cameras and editing software also create a smaller thumbnail of the image that is used by various operating systems to preview the file, this tool can be used to show the differences between the thumbnail and the full resolution of the image.
If the photo editing software did not make the corresponding change to the thumbnail (which is usually only stored in high-resolution images), it can easily be used at a quick glance to detect changes to the photo.
Forensically is available for use, and it works only within your browser, uses no add-ons, and doesn't require you to download anything online. It uses various JavaScript-based tools to analyze photos locally.
