DNA Encrypting rules with Chaotic Maps for Medical Image Encryption
K. S. Prasada Kumari, C.H. Nagaraju · 2021
Digital Images are widely used in medical diagnosis because of medical images contain sensitive information of patients. The most critical issues like attacks arise during storage and transmission of medical images through public network. To care for the privacy of patient's information, confidential sharing of medical images and computational time are challenges. To reduce these robust DNA rule-based sequences with chaotic map technique is presented. This method consists of three steps 1) The chaotic map generates the transformations to shuffles the Image Gray values to get high randomness in pixel positions 2) The DNA complement rules are generated for confusing hackers 3) Image gray values are substituted by unique DNA sequences for random distribution of pixels in the Image. Because of good confusion, random distribution properties and randomness of chaotic technique, image pixels sequence estimation is highly difficult to intruders. So that, the proposed technique runs sufficient security along with reduced computational time.
