Copyright Protection for GIS Vector Data Production

摘要：

Limited by the characters of GIS vector data,such as variety and complexity of expression,universality,mass,disorder and pretty good privacy,etc.,the traditional copyright protection methods for image and audio productions cannot be applied into GIS vector data productions directly.In this paper,a solution to copyright protection of GIS vector data productions is proposed.Firstly,information characteristics,data organization and storage characteristics and attack characteristics of GIS vector data are comprehensively analyzed.Secondly,based on hash,file filter driver,dynamic encryption and decryption,the key techniques including zero-watermarking generation,access control,and data content protection are described.Finally,an copyright protection frame of GIS vector data is put forward.
