The information security has become one of the most significant problems in data communication. So itbecomes an inseparable part of data communication. In order to address this problem, cryptography andsteganography can be combined. This paper proposes a secure communication system. It employscryptographic algorithm together with steganography. The jointing of these techniques provides a robustand strong communication system thatable to withstand againstattackers. In this paper, the filter bankcipher is used to encrypt the secret text message, it provide high level of security, scalability and speed.After that, a discrete wavelet transforms (DWT) based steganography is employed to hide the encryptedmessage in the cover image by modifying the wavelet coefficients. The performance of the proposed systemis evaluated using peak signal to noise ratio (PSNR) and histogram analysis. The simulation results showthat, the proposed system provides high level of securit
