Image Manipulation Detection
Image manipulation detection is an additional layer of check to identify morphed patterns commonly found in photoshopped images, swapped selfies, and deep fakes. This provides a comprehensive liveness detection solution, enhancing the overall security of the process.
The below visualisation represents how the combined evaluation of liveness and image manipulation scores guides the system's decisions accurately.

Swapped Face Detection
Combined with current liveness detection, VIDA aims to increase the chance of detecting, mitigating, and minimizing any face morph or face wrap occurrence, especially one that’s generated by deep fake technology.

How it Works
The image manipulation feature employs an advanced algorithm to identify manipulations in selfie images, such as those created through photo editing or morphing techniques. This feature acts as a secondary layer in the backend to safeguard against deep fakes or edited selfies, with a default threshold setting at 0.95.

Scoring & Thresholds:
Image manipulation scores range from 0 to 1. The threshold for determining manipulation is set at 0.95.
A score below
0.95indicates a genuine user, and the selfie is accepted.A score of
0.95or higher signifies a manipulated selfie, leading to rejection.

When the liveness score < 0.95 and image manipulation score < 0.95
Selfie is accepted
When the liveness score < 0.95 and image manipulation score >= 0.95
Selfie is rejected
When the liveness score >= 0.95 and image manipulation score < 0.95
Selfie is rejected
When the liveness score >= 0.95 and image manipulation score >= 0.95
Selfie is rejected
