Abstract:
Data hiding (steganography or watermarking) involves embedding secret data into various forms of digital media such as text, audio, image and video. In this paper we propose two variants of vector quantization (VQ) based steganography method to hide secret speech signal in host public speech coded by the AMR-WB (Rec. G.722.2). The secret bit stream is hidden by using the basic principle of binning scheme which is carried out in the split-multistage vector quantization of G.722.2 immittance spectral frequencies (ISF) parameters.
