Encrypted image-based data hiding technique using elliptic curve ElGamal cryptography

COVID-19 continues to dominate world news because of its severe damage to human health, which may lead to death. It has been forcing people to handle their work, studies, and examinations in the public cloud. In this situation, data security should be ensured to prevent data from being hacked or altered. One of the most promising fields in data security is DNA cryptography, which refers to using DNA molecules in storing, hiding, and transmitting the information. This systematic review discusses some cryptographic techniques and their progress. History of CryptographyCryptographic art emerged along with writing art. As civilizations evolved, humans organized into groups, families, tribes, and kingdoms. Cryptography originated from the Egyptian and Roman civilizations. More than 4,000 years ago, the ancient Egyptians used hieroglyphs to write their messages. These hieroglyphics are the oldest cryptographic algorithm, and they confirmed that hieroglyphs were used for cryptography.
