How to Spot Deepfakes

Posted by Peter Clay on Mar 6, 2023 1:59:21 PM
 The evolution of machine learning and artificial intelligence has led to the generation of deepfakes, images, and videos created to impersonate real people. Spotting deepfakes on audiovisual calls can be challenging.  

However, there are a few signs that can help identify deepfakes. 

  1. Unusual or distorted facial expressions: One of the most obvious signs of a deepfake is unnatural or distorted facial expressions. This can include unnatural movements of the mouth, eyes, or other facial features, as well as sudden changes in facial expression.

  2. Inconsistent lighting or shadows: Deepfakes can sometimes have inconsistent lighting or shadows, which can indicate that the video has been manipulated. This can include sudden changes in the lighting, shadow patterns, or areas of the video that look unusually dark or light.

  3. Audio discrepancies: Deepfakes can sometimes have audio discrepancies, such as unnatural pauses or changes in the speaker's voice. This can include sudden changes in the volume or pitch of the speaker's voice or parts of the audio that sound muffled or distorted.

  4. Unusual backgrounds: Deepfakes sometimes have unusual or unrealistic backgrounds, indicating that the video has been manipulated. This can include sudden changes in the background or elements of the background that look out of place or unrealistic.

  5. Inconsistent body movements: Deepfakes can sometimes have inconsistent body movements, which can indicate that the video has been manipulated. This can include sudden changes in the position or movement of the person's body or parts of the video where the person's body looks unusually stiff or unnatural.

It is important to note that these signs can sometimes be difficult to spot, and deepfakes can often look and sound very realistic. Therefore, it is always best to verify the authenticity of the video or audio before accepting it as genuine.
