A New Method for Color Image Steganography Using SPIHT and DFT, Sending with JPEG Format

摘要

In this research, we aim to conceal a secret data Into the cover image without noticeable degradation. In our approach, Lempelȁ3;Zivȁ3;Welch (LZW) compression and set partitioning in hierarchical trees (SPIHT) codec are used to obtain a low bit rate and high econstructed quality image compression. In the embedding process, an adaptive phase modulation (APM) mechanism and discrete Fourier transform (DFT) were adopted for secret data embedding.
