In the digital age, image falsification has become commonplace, and verifying the authenticity of photos is an important skill, especially for journalists, researchers and anyone who wants to avoid the spread of misinformation. In this guide, we'll show you how to verify the authenticity of photos using various tools.
DISCLAIMER
Checking photographs for authenticity is a process that requires an integrated approach. Google Reverse Image Search and TinEye will help you identify the source of an image and find its original, and Forensically will help you identify hidden manipulations.
Don't forget that even the best tools have their limitations, and the final result of the test depends on your care and ability to analyze the context in which the image is used. Combining technology and critical thinking is the key to successful media content review.
Base: Google Reverse Image Search
Google Reverse Image Search is one of the most popular tools for checking images for authenticity. This tool allows you to upload an image or paste its URL to find copies of the image on the Internet.
How to use:
- Go to Google Images.
- Click on the camera icon in the search bar.
- Upload an image or paste its URL.
- Google will search the uploaded image and show all of its indexed results where that image or similar images have been used previously.
Restrictions
- Like other tech giants, Google regularly adjusts its privacy policies and search results under pressure from legislators in different countries. Therefore, for example, searching by faces can be extremely difficult if the photo is not a public person, but a private person.
- If an image is extremely popular, the first post data may not be accurate.
Image search from Yandex works in a similar way. Sometimes its results can be more accurate than Google's.
Checking with TinEye
TinEye is a powerful reverse image search tool that helps you trace the origins of images and find their originals, as well as compare different versions of a file. Unlike Google, TinEye provides the ability to sort results by date, which allows you to guess fairly accurately when an image first appeared on the Internet.
How to use:
- Go to the site TinEye.
- Upload an image or paste its URL into the search bar.
- TinEye will analyze the image and show all the sites on which it appeared, including information about the date it first appeared.
Restrictions
- TinEye does not index all images and not right away. This tool works best with viral images that were published some time ago.
Analysis using Forensically
Forensically is an online tool that provides advanced image analysis techniques such as Error Level Analysis (ELA), metadata analysis, and manipulation identification. This tool is especially useful for identifying hidden changes in images that may not be visible to the naked eye.
How to use:
- Go to the site Forensically.
- Upload the image you want to check.
- Use various analysis tools such as ELA to identify areas of the image that may have been changed or added.
Restrictions
- You should remember that this is not a magic wand and carefully study the instructions for the instrument. For example, this tool is not suitable for studying still images from videos.
