“…For multimedia steganography, Shastri and Thanikaiselvan [20] proposed a dual image RDH algorithm using Prediction Error Expansion (PEE) and achieve good performance. Gui et al [21] proposed a novel reversible data hiding (RDH) scheme based on reference pixels and adaptive block selection, which can adaptively embed data into the smooth blocks and less modification is made to noisy ones. Cheonshik Kim et al [22] proposed adopt pixel overlapping approach, optimal pixel adjustment process (OPAP), and LSB substitution to construct the Hamming+k with m overlapped pixels DH (Hk-mDH).…”

In secure communication, finding bits that used for steganography is essential for effective and high-quality speech information hiding. This paper presents an adaptive speech information hiding method based on K-means, which can quickly find hidden bits. This method uses K-means algorithm to detect effective hidden bits through clustering and embeds secret information with different matrices to achieve good efficiency utilization of hidden bits. This proposed method embeds secret information according to the clustering result and the matrix coding at the transmitting end and extracts the secret information according to the corresponding embedding matrix ate the receiving end. Thereby implementing secure communication over VoIP. The experimental results indicate that the proposed method has better speech quality (PESQ is reduced by about 1.5%) while achieving a higher embedding capacity (up to 976 bit/s), and it shows strong concealment.
