Robust and Secure Watermarking of Medical Images Using Möbius Transforms

Watermarking medical images is essential to ensure data integrity, authentication, and secure information transfer in healthcare systems. This paper explores the application of Möbius transforms, a non-linear transformation technique, for robust and secure watermarking of medical images. Our approach optimizes Möbius transform parameters through an evolutionary algorithm. Comprehensive experiments subject medical images to common attacks, evaluating the robustness of the Möbius transform-based watermarking (MTW) method using performance measures. The findings demonstrate significant resilience, maintaining image quality and watermark integrity. This paper enhances medical data security, contributing to secure medical imaging systems, advancing reliability, and confidentiality in healthcarepractices.
