Abstract
The applications of spatial database are more and more popular in the computer and network environments. It is the reason why information security is an important issue now in our world. The purpose of this paper is to integrate the spatial database processing technique and the access control in a hierarchy technique to enhance the security of spatial database. Combining the concepts of traditional cryptography and steganography, a new spatial database cryptosystem with double security mechanisms is proposed.
