The Steganography Lab in Omni provides tools for detecting and extracting hidden data from images using various techniques.

Features

LSB Visualization

Displays the Least Significant Bit plane of an image, making hidden data patterns visible to the analyst.

LSB Text Extraction

Attempts to extract text data hidden in the LSB of image pixels. Supports multiple encoding schemes.

Channel Isolation

Isolate individual color channels (R/G/B) to analyze data hidden in specific color planes:

• Red Channel: Extracts and displays only red pixel values
• Green Channel: Extracts and displays only green pixel values
• Blue Channel: Extracts and displays only blue pixel values

Chi-Square Analysis

Performs chi-square distribution testing to detect statistical anomalies that may indicate steganographic content.

This statistical test compares observed pixel value distributions against expected distributions to identify hidden data.

Usage

1. Upload an image file to the Metadata Lab.
2. Navigate to the Stego Lab tab.
3. Select the analysis method:
   • LSB Visualization
   • LSB Extraction
   • Channel Isolation
   • Chi-Square Test
4. Review results for hidden content indicators.

Technical Details

The StegoAnalysis component in src/components/steganography/ handles all steganographic analysis operations client-side for privacy.

Results can be exported to PDF for forensic reporting along with other investigation findings.
