Encryption and Secure Transmission of Telemedicinal Image in Watermarking using DWT HAAR Wavelet Algorithm

Abstract

This is a result paper .In this paper, watermarking using DWT Haar wavelet algorithm is used.In this papera patient brain image which is to be transmitted using telemedicine is encrypted and the records of patient brain condition is hidden along with patients document and is transmitted along the channel which can not be decrypted by any unauthorized section. The main aim of this paper is to hide the patient information along with the image and to encrypt and transmit the data along with images and to protect it from different kind of attacks and noise that mainly take place in channels. The purpose of using watermarking is that watermarking does not influence the diagnosis to be made by reducing the visual clarity of medical images. Watermarking is implemented here using DWT haar wavelet and the process include complete copyright protection. Experimental result show high imperceptibility where there is no noticeable change in the watermarked image and original image and the patients records is also hidden along with the image which is to be transmitted along the channel that cannot be hacked or attacked by any unauthorized section. The robustness of watermarking scheme is analysed by means of performance evaluation of peak signal to noise ratio (PSNR)
