Increasing need for telemedicine in healthcare industry created a great necessity to secure and transmit the data among medical centres. In this paper, DNA Based Approach for Partial gray scale Image Encryption have been presented. In this algorithm, original gray scale image split into eight binary layers. 4-DNA planes are obtained by applying the DNA encoding process for original gray scale image. Based on the chaotic map sudoku like random image is generated. Random image also undergo DNA encoding process to produce 2 DNA sequence based bit planes. According to random bit plane selection table, select a 2-DNA planes and perform a DNA addition with the chaos based 2-DNA planes. Finally apply the DNA decoding process to get the Partial encrypted gray scale images. Simulation result shows that the proposed algorithm suitable for the medical information security.
