Spread-Spectrum Digital Watermarking & Military Communication
Xin Wang · Journal of Military Communications Technology · 2005
Information security is the principal problem of military communication in infor-mation war,and information hiding is an effective complement of the conventional encrpytion techniques,which yield better results in hiding information in the military.In this paper,the research background of information hiding was introduced,spread-spectrum watermarking model and algorithm were discussed and experiments on two basic communication watermakings were made.The results demonstrate this spread-spectrum digital watermarking is very feasible.
