Abstract

The proposed speech steganography method exploits the sparse representation to embed secret messages into the cover signal. Here proposed a novel wavelet domain speech steganography method, called the DWT-SD method, by exploring the sparse representation of wavelet coefficients. The low frequency wavelet sub-band is sparsely represented over the dictionary estimated from the high frequency wavelet sub-band. The secret messages are embedded into elements of the sparse representation. The secret bits are embedded and they could be decoded at the receiver side.
