Abstract
GIS data is digital content that requires high initial production cost and it is transformed into different digital content according to its usage or access level. The convenience of digital content has increased the demands of the content, but because of characteristic of digital content which can be duplicated unlimitedly, the issues on security and copyright have been raised frequently. This paper proposes multi-level access control using Delta Compress Algorithm and by granting access control based on usages and permissions of content, it prevents the illegal use of GIS data which will protect and maintain digital contents consistently. Multi-Level Access Control using Delta Compress proposed in this paper is applied to all digital content in the same way and the same application is possible to Raster Image without additional work for file format.
