Also known as: Steganalysis – Raw Quick Pair
A steganalysis method examining pairwise pixel value relationships to detect hidden data in images.
DESCRIPTION
Raw Quick Pair steganalysis analyzes pairings of pixel values to identify statistical anomalies introduced by embedding, particularly in LSB schemes. It estimates payload presence by comparing expected and observed pair distributions. The method is computationally light and effective for certain embedding rates and image types. It complements other detectors like RS analysis and chi‑square tests. Robust embedding or pre‑processing can reduce detection power, requiring ensemble methods. It is used in digital forensics and content protection workflows.
