Coverless Data Hiding in VoIP based on DNA Steganography with Authentication

[摘要] Data hiding in Voice over Internet Protocol (VoIP) using coverless approach improves the undetectability bypreserving the cover bits from modification. This paper focuses on hiding the secret message in VoIP streams usingDeoxyribonucleic Acid (DNA) steganography approach. DNA steganography is known for its low cracking probability. Theembedding process is done in two steps. The first step converts the VoIP sample, secret message and a user generated key (forAuthentication) into m-RNA pattern during transcription and the second step converts the m-RNA to form a triplet duringtranslation process to create a protein array, where the secret message is embedded. The secret message is extracted from theprotein array by applying reverse translation and Transcription. The proposed approach improves the undetectability byleaving the cover bits unmodified with Perceptual Evaluation of Signal Quality (PESQ) values 84% comparatively greaterthan the state of art techniques.
