Biometric Embedded Non-Blind Color Image Watermarking with Geometric Tamper Resistance via SIFT-ORB Keypoint Matching
This research introduces a non-blind color image watermarking framework designed for robust tamper detection, especially under geometric transformations. It integrates two watermarks—a personal signature and a biometric fingerprint—into a composite watermark. This composite is embedded into the chrominance component of the cover image using a multi-level transform domain approach (DWT-DCT-SVD). The framework leverages rotation-invariant SIFT and ORB descriptors for tamper detection, mitigating "transformation-induced tamper obfuscation" (TITO) without requiring alignment. Extensive experiments show high perceptual fidelity (PSNR 50-55 dB, SSIM near 1) and resilience to various attacks, outperforming existing techniques.
Executive Impact: Key Metrics
The proposed AI solution delivers enhanced security and integrity for digital assets, crucial for industries like medical diagnostics and e-commerce. Its robustness against geometric transformations ensures reliable authentication, preventing costly data breaches and maintaining trust in digital content, directly contributing to compliance and operational resilience.

Composite Watermark Strength
0 Unified Biometric & Signature WatermarkThe fusion of a biometric fingerprint and a personal signature into a single composite watermark (W_f) enhances both identity authentication and robustness. This bit-plane level fusion preserves perceptual transparency while embedding high-level identity features, making the authentication data semantically rich yet imperceptible.

Superior Robustness Against TITO
The system achieved PSNR values ranging from 50 to 55 dB and SSIM indices near 1 across multiple benchmark images, demonstrating high perceptual fidelity. It showed notable resilience against JPEG compression, median filtering, Gaussian noise, and various geometric distortions including rotation and scaling. Comparative analysis consistently demonstrated its superiority over existing grayscale, color, SIFT-based, and DWT-DCT-SVD-based watermarking techniques, affirming its applicability in scenarios demanding secure, imperceptible, and transformation-invariant image watermarking.
Challenge: Transformation-Induced Tamper Obfuscation (TITO)
Solution: Integration of SIFT and ORB keypoint matching for geometric tamper resistance.
Result: Consistently outperforms state-of-the-art methods in PSNR, SSIM, and tamper detection accuracy under various attacks, including severe geometric distortions.
