This paper proposes a scheme of real-time secure communication system based on information hiding and speech recognition. The algorithm uses speech recognition to reduce the bit-rate of secret speech greatly. Then we design an information hiding algorithm by adaptively choosing embedding locations and adopting the multi-nary modulation technique.(More)
Digital steganography introduces statistical distortion to some extent. Thus, steganalysis can be used to classify an object with or without hidden information. In this paper, we present a novel approach to detect the presence of LSB (least significant bit) steganographic messages in the voice secure communication system. A distance measure, which has been(More)
