In this age of misinformation being spread at a supersonic speed, we present to you a set of different tools that can help to identify the authenticity of picture via reverse image search.
1.Google:
Google has its reverse image search tool which is a content-based image retrieval (CBIR) query technique that involves providing the CBIR system with a sample image. The system does its search on this given image and retrieves image information. The input image can be an image or its URL, the tool constructs a mathematical model, compares the image with billions of other images on the Google databases before giving similar image results. It can also be used to find out if the given image has been edited.
2.TinEye:
TinEye is a search engine specializing in reverse image search. An input image to analyse is given to TinEye with which it creates a unique and compact digital signature nad matches it with its indexed images. Using this tool you can find places online where the same input image or similar images have been uploaded. The tool can find most changed, oldest and newest repetitions in the images.
3.Pixsy:
Pixsy tool detects needs the image to be uploaded on the Pixsy platform which it matches with the images on the internet. For unauthorised use, Pixsy offers a compensation recovery service for commercial use of the image owners work. In order to bring resolution for copyright infringement, Pixsy partners with over 25 law firms and attorneys around the world.
4.Fake Image Detector
Fake Image Detector uses the picture given to authenticate, like movie poster or an image in a magazine am the tool will allow to check the Exchangeable image file format data, or Exif data of the photo. This can include the date and time when the picture was taken, the location and sometimes even the type of camera or phone that took it as well as the name of the owner.
5.JPEG Snoop
On uploading an image here for the purpose of examination, you will be able to see all the information with regard to the image and also find out if there were any edits made in it. I can analyse images in the format of jpeg, pdf, avi and thm.

7.Photo Forensics:
Photo Forensics is a tool to tell what was changed in a photograph. The website runs on error level analysis (ELA), using which it identifies areas within an image that are at different compression levels to find what has been edited in the picture. At the end, it also tells how the picture has changed from its original state. It also tells about the EXIF-data of the image in question. FotoForensics provides the algorithms, online tutorials for self-paced learning, challenges to test your knowledge, and other resources to help you get started.
8.Ghiro:
Ghiro is an Open Source software for digital photo and digital image forensics. The forensic analysis is fully automated, report data can be searched or aggregated in different perspectives. It is used to find the manipulations done to the original image. It calculates the difference in compression levels of the two images and checks if the differences or the edits are high.
9.Forensically:
Forensically is a set of free tools for digital image forensics. It includes clone detection, error level analysis and information extraction of the desired image. It is used to find what changes have been done to the image easily, isolates noise and can identify manipulations done like airbrushing, deformations, warping and perspective corrected cloning.
10.Veracity:
An app to find fake information on images, Veracity is an Apple app that uses reverse image search and allows you to find out the subject of a photo, discover where on the internet the picture exists and the edits that have been made to the original image.
