In a digital watermarking scheme, it is not convenient to carry the original image all the time
in order to detect the owner's signature from the watermarked image. Moreover, for those
applications that require different watermark for different copies, it is preferred to utilize some
kind of watermark-independent algorithm in extraction (does not need a priori knowledge of
the watermark). In this paper we introduce a novel approach called WMicaT that employs an
independent component analysis technique in watermark embedding and extraction. Using …
