Cryptography with dynamic DNA depending on edge detection

Abstract EN

Making the data secure is more and more concerned in the communication era.

This research is an attempt to make a more secured information message by using both encryption and steganography.

The encryption phase is done with dynamic DNA complementary rules while DNA addition rules are done with secret key where both are based on the canny edge detection point of the cover image.

The hiding phase is done after dividing the cover image into 8 blocks, the blocks that are used for hiding selected in reverse order exception the edge points.

The experiments result shows that the method is reliable with high value in PSNR.
