We present a novel quantization-based digital audio watermarking scheme in wavelet domain. By quantizing a host audios wavelet coefficients (Integer Lifting Wav
We propose a data hidding technique in a still image. This technique is based on chaotic sequence in the transform domain of covert image. We use different chao
Energy-efficient data gathering in multi-hop wireless sensor networks was studied,considering that different node produces different amounts of data in realisti
