Web behind Web - A Steganographic Web Framework

This paper presents a Web framework as an application of steganography. The framework enables us to stealthily organize a tree of Web objects behind another. The Web objects to be embedded are automatically assigned to cover files appropriately. When embedding is done, we obtain stego-objects those can be uploaded to a Web server as ordinary Web objects. We can retrieve files embedded in stego-objects by a common Web browser via a dedicated proxy.
