Abstract

This chapter explores medical signal security enhancement using chaotic map and watermarking techniques. This new approach provides security to both the medical image and also maintains the confidentially of both the patient and doctor. Medical image encryption is done by using 2D Gaussian iterated map and BARCODE ECC200. Personal data is encoded in barcode. The encrypted image and barcode are embedded using DCT and DWT, which provides high PSNR values and higher NC value, which help to provide more security.

Background

Different approaches have been proposed for providing security to medical images. Like medical image encryption, authors generate pseudo random numbers by using chaotic maps and applying XOR operation with each bit of image pixels. Some approaches provide security to both personnel and medical image at the same time. The following section deals with the work done by different researchers in this area.
