Perceptual Hashing: Robust Fingerprint Generation
Creating robust image fingerprints is crucial for distinguishing malicious manipulations from legitimate transformations. RDIAS employs advanced perceptual hashing to ensure high sensitivity to changes in semantic meaning while tolerating benign operations like resizing or transcoding.
| Method | Sensitivity (Higher is Better) | Robustness (Higher is Better) | Discrimination (Lower Collision Prob. is Better) |
|---|---|---|---|
| Average Hash (aHash) | Moderate | Low | 1.02 x 10-5 (100-bit, τ=0) |
| Difference Hash (dHash) | Moderate | Moderate | 1.01 x 10-14 (100-bit, τ=0) |
| Wavelet Hash (wHash) | Moderate | Moderate | 5.54 x 10-7 (100-bit, τ=0) |
| Perceptual Hash (pHash) | Highest (Consistently) | Highest (for τ > 2) | 1.09 x 10-51 (256-bit, τ=0) |
| Facebook's PDQ | High | High | 4.22 x 10-55 (256-bit, τ=0) |
| Apple's NeuralHash | High | Moderate | 2.69 x 10-16 (96-bit, τ=0) |
Conclusion: pHash with 256-bit fingerprints emerged as the most suitable method, balancing high sensitivity to malicious changes with robustness against legitimate image transformations and a virtually zero collision rate. This ensures that RDIAS can reliably distinguish authentic images from manipulated ones.
Imperceptible Watermarking: Securing Image Integrity
Embedding authentication information into images without degrading visual quality is a key challenge. RDIAS utilizes advanced deep learning-based watermarking to achieve high robustness and imperceptibility.
TrustMark: The Chosen Embedding Solution
After evaluating various deep watermarking methods, TrustMark was selected for RDIAS due to its superior performance. TrustMark consistently demonstrated the highest Bit Accuracy Rate (BAR), averaging 99.08% across diverse transformations like transcoding, resizing, noise, and filtering (Table 2).
Crucially, TrustMark also excelled in preserving image quality, achieving a PSNR of 44.04 dB, SSIM of 0.997, and LPIPS of 0.001 (Table 3). These metrics confirm that the embedded fingerprints are virtually imperceptible to the human eye, ensuring RDIAS's practicality for widespread adoption.
Ensuring Fingerprint Integrity with ECC
Image transformations and manipulations can introduce bit errors into the embedded fingerprints. RDIAS incorporates Error Correcting Codes (ECC) to reliably recover the original authentication information, ensuring system robustness.

Select BCH Codes (Optimal for Short Messages)
Rationale: Through detailed analysis of error patterns—uniform distribution, symmetric bit flips, and non-bursty errors (Figure 5, Table 4)—BCH (Bose-Chaudhuri-Hocquenghem) codes were identified as the most suitable ECC method. BCH codes are computationally efficient and highly effective for the relatively short message lengths (256-bit fingerprints) used by RDIAS, outperforming Reed-Solomon codes in efficiency (Figure 6).
Real-world Performance: AI Manipulation & Platform Robustness
RDIAS underwent rigorous end-to-end evaluation against sophisticated AI manipulations and realistic transformations by social media platforms, demonstrating exceptional accuracy and robustness in challenging scenarios.
99.0%
DeepFake Detection Accuracy
The system achieved an impressive 98.11% accuracy for detecting general AI-powered manipulations (object addition/removal, cropping) and an outstanding 99.0% accuracy for DeepFake face manipulations (Expression Change, Face Swap), with 100% recall and low false alarm rates (Tables 5, 7).
RDIAS also maintained high accuracy (above 93%) even when images were sequentially uploaded and downloaded across multiple platforms (Facebook, Telegram, WhatsApp), each applying different transformations. With immunization taking under 850 ms and verification under 50 ms, RDIAS is designed for real-time, scalable deployment, including as a web-browser plugin (Table 13, Figure 9).
