Recently the utilization of GIS (Geographical Information System) is becoming rapidly pervasive. Consequently new methodology of archiving and managing images is pressing problem for GIS users. It is also expected that as the utilization of GIS become widely spread, protecting copyright and confidential images are more important. In this paper we propose a three-layer image data format that makes it possible to synthesize two kinds of related images and analysis information in one image data size. To achieve the confidentiality of one hidden image, we apply the private watermarking scheme, where algorithm is closed for public. In the proposal model, encoder netlist embedded in 3^<rd> layer is generated by FOL prover to achieve more secure and less information to decode it compared with one operation of another block cipher such as RSA. Proposal system users can process two images without the cost of maintaining key and decoding operation.
