Implementation of medical image watermarking technique using FPGA

Abstract

Protection and confidentiality are essential for Medical Image Watermarking because thorough analysis on health pictures is needed for proper diagnosis. In this paper we address this problem and designed a watermarking algorithm for medical images. Protection resolutions are increasingly joined alongside biomedical images. The patient data and patient fingerprint are added to the medical images, without disturbing the essential information in an image. Consequently, watermarking algorithms that involve embedding the patient report and finger print are proposed. In this method we are separating Region of Interest and Region of noninterest pixels from medical image using MATLAB. We have used RONI for adding watermark (patient report and fingerprint) to the medical cover image. In this paper we designed a new method to protect and authenticate medical images. We developed Independent Component Analysis on A Field programmable Gate Array (FPGA) and applied to RONI image that enables the addition of watermark. In this way X ray or scan report are utilized for watermark creation and for patient authentication. The aim of proposed technique is assembly of Independent Component Analysis watermarking to insert two autonomous data’s for accuracy and authentication.
