Design and Implementation of Digital Watermarking System for Geospatial Data
摘要
Abstract
It has become popular to apply the security managing system for the geospatial data based on the digital water-marking system today. A digital watermarking system is designed and implemented for the geospatial data after analysis of its current requirements. This system could effectively protect the copyright of the data producer,track the illegal data, and control the area of data usage,etc. Thus,the security of geospatial data is ensured. Now this system is applied suc-cessfully,and may have a more broaden view of application.关键词
