Abstract :Tele-radiology is an emerging field in the stream of medical diagnosis in which maintenance and transmission of the medical reports like MRI, CT-Scan and X-Ray can be done through internet. The main objective of Tele-radiology is automated report handling of the patients and accessing the report by proper authorization. The issue arises at verification, validation of the medical images sent through the internet. To address the issue of verification, in this paper we have used a secret key image with bit-x-or encryption methodology, first a key image of the physician is taken, as a reference and a secret key is generated by using bit-X-OR operation which is further used as original key for encrypting the watermarked image . The validation of medical images authenticates the patient image to whom the particular report belongs and this process is addressed by using watermarking methodology implemented through wavelet based counter let transform (WBC). The encryption of the image is done post to the watermarking. The efficiency of watermarking methodology is verified with PSNR, MSE and Correlation Coefficient, significant improvement is observed in proposed methodology.
