description In a watermark embedding method and apparatus, a layered three-dimensional model is aligned in a printing direction based on a layering direction of the layered three-dimensional model. Then, a watermark having a predetermined pattern is embedded into the aligned three-dimensional model in a direction orthogonal to the printing direction so that the embedded watermark is not associated with the printing direction.
