Abstract: Watermarking is a popular method for copyright protection. This technique seems to be very popular and helpful for protecting the privacy of patients by doing watermarking procedure on medical images. In this watermarking scheme a text image is created which may vary from patient to patient and is embedded on the MRI images to generate a secure image which contain hidden patient data (not visible to naked eyes). Two methods are implemented for watermarking i.e. Discrete Wavelet Transform and Singular Value Decomposition. The PSNR (between original MRI image and generated secure image) and correlation (between patient text information and extracted watermark image) are calculated to check the robustness and capacity of the scheme.
