Overview

Proposed digital watermarking method improves patient privacy and image quality in MRI, suggesting robust defence against tampering.

Key Points

  • This work aims to enhance patient privacy through a secure watermarking system embedded in MRI images.
  • Developed a semi-fragile watermarking scheme using DOST and LBP features.
  • Incorporated chaotic mapping and Arnold scrambling for enhanced security.
  • Evaluated performance using two MRI datasets with metrics including PSNR, SSIM, and NCC.
  • Achieved 79.84 dB PSNR and 0.9969 SSIM on TCIA MRI dataset, improving by 111.61% and 4.35%, respectively.
  • Maintained a mean NCC of 1, demonstrating strong robustness.
  • Showed resilience to noise and high sensitivity to deterministic manipulations like JPEG compression.
