Popis: A color image steganography method to conceal a secret data into the cover image in the frequency domain is suggested. In this method, Lempel–Ziv–Welch (LZW) compression is used to obtain a low bit rate; Also Linear Feedback Shift Register (LFSR) technique is used to enhance the security of the scheme. In the embedding process, an Adaptive Phase Modulation (APM) mechanism and Discrete Fourier Transform (DFT) are used for secret data embedding. Abilities of the proposed method are high speed and security, because of using hardware element LFSR and Data Encryption Standard (DES) cryptography.
