Abstract :
In this research, we aim to conceal a secret data Into the cover image without noticeable degradation. In our approach, Lempel-Ziv-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.
