Hybrid Speech Steganography System using SS-RDWT with IPDP-MLE approach

Generally, defence applications need the high secured communication over channel. Most of defence-based communications are performed through audio and speech signals in environment. To provide security to these digital media signals, considerably advanced technologies implementing last two decades. However, transmission unsecured channels creating several big problems data transfer due equivalence works, plasticity, ease replication unauthorized use format data. The possible solution is secure by cover writing using steganography, so effectively hid speech. overcome problems, this article mainly focussing on securing message hybrid steganography approach. This system implemented with spread spectrum-based redundant discrete wavelet transform (SS-RDWT) additional pause removal properties. input signal contains a larger size, requires higher power usage, computational time extra storage capacity. Thus, an intelligent detection protocol (IPDP) remove pauses reduces size signal. performance IPDP improved maximum likelihood estimation (MLE) procedure. Finally, SS-RDWT along IPDP-MLE-based mechanism. simulation results show that proposed method gives better against various noise attacks robustness, imperceptibility as compared conventional approaches.
