Novel concept of bionic Morse coding for mimicry covert underwater communication

A novel method for covert underwater communication based on Bionic Morse coding mimicking using humpback whale songs is presented in this article. Information entropy is used to transform heterogeneous humpback whale vocals as a cetacean Morse code. The Natural singing of male humpback whale was designed for transmission of covert signal; The transmitted signal will not be detected due to similarity with the natural signal and interceptor will not detect the transmitted signal as it is similar with the natural singing of male humpback. The proposed novel gives lesser approach of recognition of natural sound. It has high imperceptibility and have zero chance of deciphered as we have presented an exemplary covert hydro communication. For each character of English language, a mimicry Morse code is developed and compared with conventional coding methods. Proposed method results higher covert data rate with less complexity. The secret and stealthy communication is achieved with the transmission rate of 1 character in each second of time.
