摘要：An apparatus and method for embedding a watermark into original information,transmitting the watermarked information, and reconstructing the watermark areprovided. The method includes (a) embedding a predetermined number of componentsof a plurality of components constituting the watermark into the original information,and (b) using the remaining components as keys for reconstructing the watermark.According to the method, since the size of data to be embedded is greatly reduced,degradation of watermarked information is prevented, and the information becomesmore robust against attacks occurring in a variety of ways when transmitting theinformation.
