The applications of spatial database (2D and 3D vector maps) are more and more popular in the computer and network environments. It is the reason why information security is an important issue. Data hiding schemes may include map data authentication, secret communication for the purposes of copyright protection, integrity authentication, or secret communication. The purpose of this paper is to proposed novel StegoHash algorithm to enhance the security of spatial database. This algorithm is more appropriate for hiding data in vector maps because the distortions can be removed after the hidden data have been extracted.
