A Survey on Image Cryptosystems based on DNA Inspired Approaches

The image data are large in size with highly correlated adjacent pixels. Therefore, the conventional data encryption technology is inadequate to effectively deal with such kind of data for ensuring their security. Deoxyribonucleic Acid (DNA) encryption is a frontal encryption technology as DNA molecule has a large data capacity, vast parallelism and has low ultra power requirement. Over the years, different image cryptosystems have been proposed with the use of DNA based encoding/ decoding and its sequential operations. The present paper provides an indepth analysis of the research carried out by different authors in the last decade uptill now as reported in the literature. It also provides a pathway for further research in the area.
