Xiaojian Wang · Dianzi Ke-ji Daxue xuebao · 2008
Watermarking is the method of embedding invisible message in digital works. In this work, by analyzing digital-analog (DA) and analog-digital (AD) process, a novel method of printed meaningful watermarking is proposed based on singular value decomposition (SVD). The distortion of printing and scanning is analyzed. The experiment result shows that the method is feasible for embedding and detecting watermarking in printing.
