A method and a system for embedding information in document data that include text written in a page description language. The reflective body including transparent material has a transmission surface and at least one unmetallized reflection surface. An image creating unit selects a light source emitting the illumination light having the optimum emission frequency from among prepared light sources, receives reflected light of the illumination light from the selected light source, and creates the distance image showing the distance to the object. The compound elicits high level of toxicity to gynecological cancer cell lines such as MCF-7, T47D, MDA-MB-468, HeIa. The browser can receive information from the document manager.
