Real Time Medical Image Encryption Based on Digitial Hologram in Various Optical Domains

Abstract The use of digital hologram (DH) in optical medical images is analyzed in this paper. These analyses are done in various domains of double random phase encoding and it has been proposed. The domains are fractional Fourier, Gyrator, Fractional Hartley and Fresnel. In order to use in real time scheming, this proposal are used many medical images such as MRI Scan, X-ray and mammograms. These medical images are optically explored with the various domains of double random phase encoding. At that time, various encryption areas in double random phase encoding (DRPE) are considered with boosted confidence of security. The encryption and decryption process in various domains makes the complete chart analysis for all kind of medical images which can be used for real time processing. Simulation analysis and results shows the legitimacy and efficiency of proposed scheme.
