Abstract
Information is embedded in a three-dimensional geometric model in a visible or invisible state by changing geometric parameters of a three-dimensional geometric model. The three-dimensional geometric model comprises polyhedrons, lines, a set of points, or curved surfaces which are primitives (components) of the model. Each primitive is defined by a geometric parameter. The geometric shape of a three-dimensional geometric model is defined by a set of many geometric parameters. The information is embedded by changing the geometric parameters of a plurality of primitives constituting a three-dimensional geometric model.
