Medical images are highly sensitive and require robust methods to ensure authenticity, Data verification, and resistance to various attacks. The Proposed method “Non Blind Digital Medical Color Image Watermarking Using SVD and FFT” typically outlines a method that integrates singular value decomposition (svd) and fast fourier transform (fft) for embedding watermarks in medical images [4], [6]. This method guarantees that the watermark remains resilient against different types of attacks while maintaining the image's clarity. The non-blind nature of the watermark extraction process means that it can be done without relying on the original image, making it particularly valuable in medical imaging where maintaining the integrity and authenticity of the data is of utmost importance. Experimental results demonstrate that the method achieves high imperceptibility with minimal visual impact on the original image, ultimately; this approach ensures reliable watermark extraction, assuming the original image is available, making it suitable for secure medical image sharing and telemedicine applications.
