Abstract
The digital watermarking schemes of today use pixels (samples in
the case of audio), frequency or other transform coefficients to embed
the information. The drawback of such schemes is that the watermark is
not embedded in the perceptually significant portions of the data. We
refer to such techniques as first generation watermarking schemes. In
this paper we introduce the concept of second generation watermarking
schemes which, unlike first generation watermarking schemes, employ the
notion of data features. We propose a scheme based on point features in
images using a scale interaction technique based on 2D continuous
wavelets. The features are used to compute a Voronoi partition of the
image. The watermark is embedded in each segment using spread spectrum
watermarking. In the recovery process the same features are detected,
and again used to partition the image. Then the watermark is extracted
from each segment separately
