Figure 4A and B shows the original and encrypted horizontally adjacent pixels of the image. Figure C and D shows the original and encrypted vertically adjacent pixels of the image. Figure E and F shows the original and encrypted iagonally adjacent pixels of the image. Fig 4. Medical images for co-relation analysis The image indicates the high correlation existed between the adjacent pixels in the original image is now distributed in the resulting encrypted images. 5. Conclusion Fully Homomorphic Encryption scheme is proposed. The Fully Homomorphic Encryption scheme supports both addition and multiplication.The input images and the corresponding encrypted images are shown. The DICOM image is taken as the input image. The analysis like keyspace analysis, Key sensitivity analysis, histogram analysis,correlation analysis, PSNR and MSE analysis,Noise anlysis are performed. The results are tabulated. The analysis that is performed helps us to verify the efficiency of the proposed method in medical image security. 650 A.M.
