Adaptive and efficient audio DataHiding method in temporal domain

In this paper, a novel audio steganography method is proposed. In this algorithm, first embedding threshold in the time domain is estimated. Then this threshold is used for data concealment in the time domain. The performance of the proposed scheme in terms of SNR (signal to noise ratio) and BER (bit error rate) is analyzed. An estimation formula that connects SNR with embedding threshold has been provided to ensure the transparency of embedded data. The security of this method is enhanced by using of an encryption method prior to the data embedding step. Proposed scheme is a high velocity method because of its implementation in the temporal domain. Experimental results demonstrate that the proposed method has high payload, full and blind recovery and high audio quality.
