A Robust Double Layer Steganography Technique Based on DNA Sequences

Abstract

Security of information while transmitting between parties is an essential factor. The openness of the network increases the possibility of attacking information. Cryptography and steganography are the most significant methods that achieve secrecy. These mechanisms are different from each other, but both maintain data security, confidentiality, and integrity. A combination of cryptography and steganography or a combination of the same method leads to a secure data transmission by providing a multilevel of security. This paper aims to provide a new technique that focuses on achieving secrecy for data and robustness against attacks. The technique relies on the multilevel steganography approach by encrypting the data and then hiding it using an image-based and DNA-based steganography techniques.
