DNA based SHA512-ECC cryptography and CM-CSA based steganography for data security

Abstract Providing security to all kinds of data is an essential task in the world of digital data. The data can be secured using several methods like cryptography, steganography, and watermarking. In this paper, a combination of both cryptography and steganography is proposed using SHA512-ECC and CM-CSA to secure and hide the user data into the video. Initially, the plain text is taken as an input and it undergoes IHE compression and DNA encoding. The DNA encoded data is encrypted using the SHA512-ECC algorithm. Finally, these encrypted data is hidden into the optimal pixel points of the video frames using the CM-CSA. The results confirmed that the proposed CM-CSA works well for the steganographic process for the cover media.
