Mimic Geographic Information System<bold> </bold>

With the development of the Internet, the geographic information system gets a chance to develop rapidly. Aiming at the security problems of existing geographic information systems, a Mimic Geographic Information System, i.e. M-GIS, based on mimic defense is proposed to improve the security of geographic information systems. The system consists of heterogeneous redundancy geographic information execution bodies pool, request distributor, scheduler and arbiter. Firstly, the scheduler dynamically selects the geographic information execution bodies set for processing, and then makes a mimic decision on the processing results. The experimental results show that the mimic system is more security than traditional system.<bold> </bold>
