Secure Image Steganography by Utilizing DNA Properties

In the last period, Steganography is commonly used as an alternative to encryption achieve secret communication between parties. Many methods have emerged steganography, including use of spatial domain, spread spectrum, transform and etc. On other hand, attackers also developed in revealing hidden data trying retrieve it. To increase security hiding process, some researchers found hybrid that combine steganography processes. The research aims present a new method by taking advantage properties DNA, which includes random sequence nitrogenous bases (A, C, G, T), process hybridization, occurs two single strands DNA form double strand so first are complementary second strand. following steps: First, image be encrypted encoding it into series bases, then XOR performed with for tape agreed upon sender recipient, hybridization applied before after process. results show much different from original thus they added another level image. Secondly, resulting step cover using based on agreed-upon key.
