Abstract
In this paper we deal with correlation detection fordigital ghost watermarking.First we introduce the basic principle of digital ghost watermarking.Next we explain a method of correlation detection using hard limiter.Finally by means of computer simulation, we examine a basic characteristic of HCC(hard-decision cross correlation) vs. mixture ratio, and we consider the statistical reliability of detection.
