## Functionality Overview

### Accessing Reality Defender

* Users can scan mentions for authenticity by clicking on a **mention card** in the system.

* Scanning can be triggered by selecting either the **mention title** or **mention thumbnail**

* Scan results are available within minutes in the **Reality Defender module** on the lefthand
  side of the PeakMetrics dashboard.

### Detection Methodology

**Image Detection**

Reality Defender utilizes an **Image Detector Ensemble** that aggregates results from four
distinct models to generate a comprehensive fakeness score:

1. **Diffusion Model** - Identifies fake images created using diffusion methods.

2. **Faceswaps Model** - Detects facial manipulations from face-swapping techniques.

3. **GANs Model** - Identifies artificially generated or manipulated faces.

4. **Visual Noise Analysis** - Examines texture inconsistencies to detect fake images.

### Language Support

* Reality Defender currently only processes **English-language content**.

### Image Dependency

* The tool requires **thumbnails with faces** to function properly.

* If a mention lacks a thumbnail or the thumbnail does not contain a recognizable face,
  Reality Defender will not be able to process it.

#### Thumbnail Absence

* If a mention does not include a thumbnail, the scan cannot be performed.

Reality Defender is a powerful tool for detecting media manipulation and enhancing content
authenticity within PeakMetrics.
