In the last two decades, it has been observed that there have been remarkable advancements in digital media communication. It has lots of advantages and business potential as it needs no physical media or transport. However, digital media can also create several big problems for media owners due to unauthorized use, ease of replication, plasticity, and equivalence of works in digital form. The possible solution is to secure digital media by cover writing which can also referred as steganography. Therefore, this article focusing on development of hybrid speech steganography system using spread spectrum-based redundant discrete wavelet transform (SS- RDWT). In general, speech steganography utilizes cover speech to embed the secrete message, however, the cover speech might be larger in size and contains many pauses, which requires more storage capacity, higher computational time, and even higher power usage results in system performance degradation. Hence, in addition to the proposed SS-RDWT approach, an intelligent pause detection protocol (IPDP) with maximum likelihood estimation (MLE) technique is employed for removing pause from cover speech signal, which reduces the transmission bandwidth, storage capacity and power consumption as well. Simulation results demonstrate that proposed hybrid steganography using integrated SS-RDWT with IPDP-MLE approach obtained superior performance as compared to state-of-art approaches.

“…This section describes the performance analysis of proposed hybrid speech steganography using SS-RDWT with IPDP-MLE approach. Several speech samples from various age group of male and female versions are tested with proposed SS-RDWT with IPDP-MLE approach and disclosed the superior performance as compared to existing speech steganography methods like FFT-based approach [7] and DWT-based approach [8]. In addition, it is also compared that SS-RDWT and SS-RDWT with IPDP-MLE approach for demonstrating the effectiveness of pause removal system in speech steganography applications.…”
