摘要：As there are formations there will also be every possible ways to obstruct the growth or to destruct the grown. So the world filled with technologies needs improvisation at every stride of its way to be reached out. This is more predominant when it comes to the plight of communication a major surface without which life has become a nihility. There is always a thrive to overcome the security attack and every time produce a next step ahead technology to avoid invaders via communication. And in such way boomed a technology called cryptography, where different encryption techniques emerged with their own specialities in safeguarding the essential data from out the window access. Here in this paper a combo of two techniques namely Deoxyribo Nucleic Acid (DNA) encryption and famous rule set encryption have been proposed for various Digital Imaging and Communication in Medicine (DICOM) images. This encryption technique has proven good results when checked with their correlations, Number of Pixels Change Rate (NPCR), information entropy and histogram analysis.
