digital watermarking technology is an important method of copyright protection.A new algorithm is proposed by using HVS and encryption.Watermarking information is embedded into red,blue and green component of color image respectly.It can receive better results through comparing performance when watermaring is embeded into three components respectly.The experimental results show that the watermarks are invisible and robust against common attacks,especially JPEG compression when watermarking is embeded into middle frequence band of green component in DCT domain.
