Secure Visualization of GIS Data

Modern GIS systems increasingly rely on server-side rendering and Web services for the rendering of geographical and application-specific data for both efficiency and security reasons since the underlying data sets for critical infrastructures and emergency operations are typically extremely sensitive. Given that display devices can be spread in the field on mobile devices, the ability to track and trace leaking and misuse of visualization data is of critical importance. In this paper we describe a technique to insert robust steganographic markings into the rendering process for GIS data based on context-sensitive texture adaptation along with a system architecture for marking and tracing GIS service data over a standards-based communication channel
