Abstract: Sensitive information of medical images related to the patients is important to secure from intruder. DNA cryptography is very importantmethodology to provide Security. In this paper three level Genetic based DNA cryptographic technique is proposed. In the first level the logistic Chaotic mapsareapplied to shuffle positions of Pixels in Medical Image. In second level a mutation and crossover operations of GA are used for exchanging position of binary values within the gray values.In the third level Encoding rules of DNA are applied to selected part of inImage to generate diffused unique DNA structure which is difficult to understand by the intruders. The proposed system provides high-level security and resistant to the varies attacks.
