Abstract |
Today, most Geographic Information System (GIS) data providers have a problem protecting their data from being copied and accessed by unauthorized users. Most of the researches in this area focus on how to copyright the GIS data using the concept of digital watermarking. However, watermarking has a lot of limitations and if it is used alone, it will not able to achieve the goal. In this paper, we will introduce a new mechanism to protect the GIS data by combining the Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA) cryptography algorithms with watermarking techniques. This mechanism can be applied to both raster and vector GIS data. |
