Abstract

Abstract: With the rapid growth in application and requirement for sharing geographical data, the problem of geographical data security arises prominently. The security of geographical data not only affects the healthy development of the geographical information industry, but also has connections construction of national defense and national security. Digital watermarking and encryption control techniques have become frontier techniques and effective solutions for achieving protection of geographical data. Recently, the research and application of digital watermarking techniques have experienced fast development. In this study, the research background and requirements of digital watermarking and encryption control is introduced. In addition, this paper analyzes and evaluates their theories, models and research progresses and discusses the related software development and application status. Finally, the future routes of theoretical research and applications of digital watermarking are prospected based on the developing trend of geographic information industry and information techniques.

Key words: geographical data security, digital watermarking, encryption control, research progress, application
