Deepfake Detection
Prepare for Advancing Deepfake Technology
The "Deepfake Detection Solution" is a solution that detects unnatural aspects that humans cannot distinguish from fictitious images, videos, and audio data generated by deepfake technology, and determines whether they are real or not.Deepfake technology is evolving rapidly, and we are now moving into an era where even individuals can easily create fake media. While the social impact and concerns are growing, it is said that measures need to be taken urgently, especially in the financial and media industries, where personal authentication and the credibility of information are important. Here, we will introduce an overview of deepfake detection technology and the solutions that NABLAS possesses.

What is a deepfake?
This is a general term for technology that uses deep learning to create fake videos and audio with a high degree of accuracy. Not only can it create images and voices of non-existent people, but it can also generate images and voices that look exactly like a specific individual, and the technology has advanced to a level where humans can no longer distinguish them. There are concerns that it could be used for crimes such as impersonating others or fabricating evidence, and the number of cases that develop into criminal cases is increasing worldwide.

NABLAS Deepfake Identification Solution
NABLAS plans to provide an authentication solution that can be applied to media suspected to have been generated using deepfake technology. There are two methods of provision: "simple authentication" that allows for quick authentication using API, and "detailed authentication" that is highly reliable and conducted by authentication experts. Please use the method according to your purpose. Please contact us for details.
The details of the detection technology are explained below.
Deepfake Detection Technology for Images and Videos
Techniques for detecting artifacts
A classic method is to determine whether an image is a fake by focusing on specific parts of the image and detecting unnatural points.
For example, in the image on the left, the pupil shape is a perfect circle, whereas in the generated image on the right, the shape is distorted. By paying attention to the shape of the pupil, it is possible to determine whether the image is fake or not. In addition, the following features are known to be effective in detecting fake images:
Loss or partial loss of eye color or light reflexes
◼︎ Uneven color and grayscale in the video itself
◼︎ Pupils, blinking patterns, and frequency
◼︎ Facial expressions and head movements
◼︎ Characterize the correlation and actions of each part
