Image manipulation in identity verification has become a significant concern for businesses across the globe. In this post, we will find out what exactly is image manipulation, and how technologies like AI, CNN, and Special CV filters can help us detect this manipulation.
Identity theft is a serious issue all over the world. Every year, countless individuals and organizations fall victim to identity fraud. As cyber attackers are using different tactics to steal personal identity, organizations must set up advanced ID verification solutions to safeguard their records.
Nowadays, image manipulation in identity verification has become a big headache for many businesses. Let’s find what exactly it is.
What is Image Manipulation?
Image manipulation or photo manipulation is a process that involves altering or transforming a digital image using different techniques to achieve desired results.
The photo manipulation technique is widely used to create magazine covers and photo albums. Though it is a skillful artwork, the method has also been used for fraudulent claims and to deceive the public.
Some minor changes in images are acceptable. We all make some modifications to our photographs. For example, we adjust contrast, color, and white balance to diminish flaws in pictures.
But unfortunately, over the past few years, fraudsters have started using image manipulation for carrying out financial crimes, malicious attacks, spreading disinformation, and accessing someone else’s identity.
Why Do Fraudsters Use Image Manipulation?

Image manipulation in identity verification has become quite common nowadays. Fraudsters are manipulating images for a wide range of unlawful acts. A few common ones are listed below.
To Create Fake ID Documents
In the majority of cases, cybercriminals use image manipulation techniques for creating fake IDs, which further can be used to gain access to a system or service illegally.
Fake ID documents are identical to original ones and carry a doctored photo of the authorized user. Fake IDs have been excessively used for identification.
Making fake IDs have become quite easy – thanks to the easy availability of low-cost, high-resolution printers, and photo-editing software.
To Gain Access to PII (Personally Identifiable Information)
A fraudster can manipulate your image to gain access to your personally identifiable information such as name, address, social security number, license number, bank details, and more.
To Gain Access to Biometric Face Recognition System

Scam artists can also manipulate images to get access to the facial recognition system. It is becoming a common scenario in corporate identity theft. Fraudsters are using 3D masks, and printed photos to bypass biometric face authentication systems even.
Therefore, companies need state-of-the-art identity verification solutions that can verify government-issued identity documents in real-time and catch fake IDs.
How Can Image Manipulation Be Detected
Undoubtedly, technology is making the world a better place to live. However, the technologies we use to make positive changes can also be turned against us, and image manipulation is one of its examples.
The image manipulation technique helps us achieve artistic effects. Still, on the flip side, some people misuse this technique for deceptive purposes, especially in identity verification.
So like any technology, image manipulation has been used for both the best and the worst of our imaginations. However, it does not mean we can’t prevent the misuse of image manipulation in identity verification.
Numerous identity verification providers are coming forward to help individuals and businesses detect image manipulation with the help of different technologies. Let’s get to know about those technologies one by one.
Detecting Image Manipulation using Computer Vision

Computer vision special filters are one of the effective techniques to identify the manipulation of images. It can prove a handy method when it comes to identity verification. This forensic technique lets you know if the image is digitally modified or not.
Spotting Image Manipulation Using CNN & AI

Fortunately, there is a way to verify the authenticity of such images. In 2013, the IEEE Information Forensics and Security Technical Committee launched a first forensic challenge to address this problem.
The committee produced an open dataset of digital images taken under various lighting conditions. Then they manipulated images using algorithms that included:
- Content-aware fill and patch match (for copy and paste)
- Content-aware healing (for copy/paste and splicing)
- Clone-stamp (for copy/pasting)
- Seam carving (for image retargeting)
- Inpainting (for the reconstruction of damaged parts)
- Alpha Matting (for merging)
Many people were asked to participate in this challenge and identify images as faked or never manipulated. Some of the participants were able to detect forged areas in pictures using their human visual cortex. Based on the results, researchers saw potential in CNN to detect image forgery. CNN has features similar to our visual cortex.
CNN or Convolution neural network is a class of machine learning that helps in analyzing visual imagery. Many giant tech companies are already using CNN for image classification and recognition because of its high accuracy.
Yann LeCun designed CNN in the late 90s, who was a computer scientist. CNN implements a hierarchical paradigm that works on building a network and provides fully-connected layers where all neurons are linked to each other.
Some of the famous examples of CNN in image classification include:
- Automatic tagging in Facebook
- Product recommendations in Amazon
- Google also uses it to search for users’ photos.
As fraudsters are using advanced technology to carry out image manipulation in identity verification, you can’t rely on traditional techniques to cope with this challenge.
AI or Artificial intelligence can be beneficial in detecting image manipulation. Researchers across the world are developing various forensic tools with the help of AI to determine image manipulation by examining the noise distribution, lighting, and pixel value of a photo.
Already there are some tools out there that can help you trace digital manipulation of photos. Adobe itself is finding new capabilities in artificial intelligence to detect image manipulation.
Though AI-enabled tools are in the initial stage yet, they have great potential to provide a deep understanding of a photo’s authenticity in the coming years.
