摘要: In this paper, a watermarking system based on the integer wavelet transform is proposed. A set of different wavelets was chosen for propose so their performance as watermark transmission channel can be analyzed. The embedded in second decomposition level PCM signal block wise approach, coefficients are assumed to accurately modeled Laplacian channel. attacks were performed order test system’s robustness, we found that approach robust against several such additive white noise, low pass filtering, cropping, among other attacks; best suited class developing systems identified too.
