SteganPEG: A New Benchmark for Image Data Hiding Efficiency Image steganography faces a permanent trade-off between payload capacity, visual imperceptibility, and computational speed. Traditional benchmarks often evaluate these metrics in isolation, failing to reflect real-world performance on modern compressed image formats.

SteganPEG introduces a unified benchmarking framework designed specifically to measure data hiding efficiency within JPEG pipelines. By evaluating how algorithms exploit standard quantization tables and entropy coding, SteganPEG establishes a rigorous standard for modern steganographic tools. Key Evaluation Metrics

The SteganPEG framework standardizes performance across three core dimensions:

Capacity Efficiency: Measures bits embedded per non-zero AC coefficient.

Visual Fidelity: Quantifies degradation using structural similarity (SSIM) indexes.

File Distortion: Tracks the unwanted inflation of the final JPEG file size.

Processing Speed: Benchmarks execution time during high-throughput batch encoding. Framework Architecture

Unlike older benchmarks that rely on uncompressed pixel-domain analysis, SteganPEG operates directly on the discrete cosine transform (DCT) domain. It simulates realistic transmission channels by applying varying JPEG quality factors (from QF50 to QF95). This stress-tests the payload’s resilience against re-compression artifacts and statistical steganalysis detectors. Why SteganPEG Matters

As privacy demands grow, security professionals require transparent metrics to deploy data-hiding solutions safely. SteganPEG provides an open-source, reproducible testing suite that bridges the gap between academic theory and practical, secure digital communication.
