We present two new schemes for digital steganography of point-sampled geometry in the spatial domain. To the best of our knowledge, our schemes are the first in the literature for such types of geometry. Both schemes employ a principal component analysis to translate the points' coordinates to the new coordinate system, resulting in a blind approach. In the first scheme, we establish a list of intervals for each axis according to the secret key. We then embed a bit into each interval by changing the points' position. In the second scheme, we locate a list of macro embedding primitives (MEPs), and then embed c bits (2=
