| Abstract: | A survey of the fundamentals, current activities and future directions of the digital watermark is given in this paper, and classifications of the digital image watermark are analyzed in particular Two major algorithms are briefly described: LSB in spatial domain and DCT in frequency domain. Furthermore, some typical strategies to the attacks and counter-attacks of the digital image watermarks are also discussed. |
