[](https://wiki.niamonx.io/uploads/images/gallery/2025-11/GIBnFlS0K23JGYiM-rec.JPG)
#### **Overview of the Service**
The **Visual OSINT** module β available as part of the NiamonX investigation suite β is an advanced **photo forensics and metadata analysis tool** that helps identify image manipulation, origin, and authenticity indicators.
It integrates multiple forensic technologies β including **FotoForensics-style artifact analysis**, **ExifTool-based metadata extraction**, and **CASIA AI prediction** β to deliver a complete visual intelligence assessment for investigators, journalists, and security analysts.
---
### 𧩠What the Tool Does
**Visual OSINT** performs a deep, server-side forensic analysis of uploaded images, combining pixel-level inspection, metadata parsing, and AI-driven anomaly detection.
Supported file types: **JPEG, PNG, WebP** (up to 25 MB).
Each file is securely uploaded to NiamonXβs processing server, analyzed through a FotoForensics-like API, and returned with visual and statistical breakdowns.
The system enforces a **cooldown of 30 seconds per request** and allows up to **90 seconds for processing**.

### π Core Analysis Features
1. **Image Forensics (Visual Analysis)**
The tool generates multiple forensic artifacts and comparisons:
- **Original / Compressed Copy**
- **Diff & Amplified Diff** (highlights pixel-level differences)
- **Overlay & Artifact Grid** (visualizes edited regions)
- **ELA (Error Level Analysis)** β identifies compression and tampering zones
- **Noise Map** β isolates sensor and noise inconsistencies
- **CASIA Prediction** β AI model inference from CASIA dataset to detect manipulation patterns
2. **EXIF & Metadata Extraction**
Metadata is extracted using **PHP EXIF and ExifTool** modules, including:
- Camera and software data
- Creation timestamps
- GPS coordinates (if embedded)
- Editing traces and unusual tags
- Hidden text or string data (binary text extraction)
3. **String Analysis**
The tool detects **embedded ASCII or Unicode strings**, sometimes hidden within images.
Long strings can indicate **metadata injection** or **hidden payloads**.
4. **GPS & Geolocation**
If available, GPS coordinates are extracted and highlighted for quick mapping or cross-verification.

### βοΈ Risk Score System
Each image receives a **heuristic Risk Score**, assessing the likelihood of manipulation or sensitive content presence:
- **High Risk:**
GPS data present, strong ELA/diff indicators, suspicious or inconsistent tags.
- **Medium Risk:**
Rich EXIF metadata, CASIA neutral or borderline prediction, potential editing hints.
- **Low Risk:**
Minimal tags, no GPS, stable compression, and no visible tampering evidence.
> β οΈ The score is **heuristic** β not absolute proof β and should be interpreted as an analytical indicator rather than forensic certification.

### π§ Tips for Use
- Hover the mouse over **artifact thumbnails** to use the built-in **magnifying glass (4x zoom)**.
- Enable **auto-scroll** to jump to results automatically after processing.
- Some files may return **partial artifacts** depending on compression level or EXIF structure.
- Long embedded strings or missing ELA layers can be signals of **steganography** or **format re-encoding**.

### πΎ Request History
- Stored **locally only** (up to 50 entries).
- Records include: filename, file size, GPS presence, calculated risk score, and main detected features.
- No data or images are stored on NiamonX servers after processing completion.
---
### π‘οΈ Security & Privacy
All image uploads and forensic analyses are processed via **secure, encrypted channels**.
The service never retains or shares the uploaded files or results.
Each request is isolated and deleted after processing to maintain strict **data confidentiality** and **user privacy**.
Users are encouraged to perform analyses only on **legally obtained images** and to respect privacy and consent regulations when handling visual materials.
