Because the proposed system has similarity to digital steganography techniques in the information processing field in that the secret data is hidden in the publicly known signal (cover data), we call it wireless steganography. In this paper we propose a realization of the system using spectrum spreading signal into other information signal. To quantitatively analyze the performance of the proposed techniques, computer simulations are carried out. The results of the simulation show the effectiveness of the proposed scheme to realize the confidential and secure
