ABSTRACT:
An apparatus and method for watermarking that uses elemental images of an integrated image having three-dimensional information as a watermark are disclosed. The watermarking apparatus in accordance with an embodiment of the present invention includes i) a computational pickup unit, which picks up an elemental image watermark computationally by placing an object three-dimensionally, ii) an embedding process unit, which embeds into a two-dimensional image the elemental image watermark obtained by the computational pickup unit, iii) an extraction process unit, which extracts the elemental image watermark by receiving through a transmission channel the watermarked two-dimensional image embedded by the embedding process unit, and iv) a computational reconstruction unit, which computationally reconstructs the elemental image watermark extracted by the extraction process unit to a distance-based image.
