In a long-term perspective of development of spatial information industry, security regulation, such as limiting public picture resolution of aerial photographs, needs a rational improvement. However, unplanned deregulation of spatial information could lead problematic results such as national security issues because its present security management system is not established in reasonable manner. The main purpose of this research is to suggest the improvement plan of spatial information security management system to meet the reducing security regulation in accordance with changes of political and economic condition including current national spatial information security polices and spatial information industry. From an analytical standpoint, we examined the overall aspects of legal, operation management, and technical system while we maintained especially integrated perspective of spatial information security management. Followed by investigation of spatial information security issues, as well as its regulation and policies in overseas, rational improvement plan of security management is proposed in the aspects of legal, operation management, and technical system. It is also suggested the three-step improvement plan of reducing regulation of security management system.

In the spatial database systems, it is necessary to manage spatial objects that have two or more aspatial information with different security levels on the same layer. If we adapt the polyinstantiation concept of relational database system for these spatial objects, it is difficult to process the representation problem of spatial objects and to solve the security problem that is service denial and information flow by access of subject that has a different security level. To address these problems, we propose a polyinstantiation method for security management of spatial objects in this paper. The proposed method manages secure spatial database system efficiently by creating spatial objects according to user's security level through security-level-conversion-step and polyinstantiation-generation-step with multi-level security policy. Also, in case of user who has a different security level requires secure operations, we create polyinstance for spatial object to solve problems of service denial and information flow.

The utilization of underground space has recently increased with the complication of road, the rise of the land price, and the development of green technology. Underground space ranges from classical excavations to subway, underground cities, and shopping malls where there are crowds of people. At this time, government has spent a lot of money in installing various types of safety facilities for preparations of increasing potential disasters. Therefore, an effective facility management system is required. In this paper, we propose an information retrieval process to effectively extract the facilities' information based on the ontology and spatial analysis in underground space. The ontology-based searching supports hierarchical and associated results as well as knowledge sharing with hierarchy concepts. The spatial analysis based searching has "Buffer" and "Near" functions to operate on a map without understanding any property of the facility information.

Establishment of safety net for the socially disadvantaged attracts large attention because of the recent crime increasing against vulnerable groups. For the successful establishment of social safety net, the test-bed for evaluation and realization of crime-related research results is required. However, previous R&D test-bed projects such as The Korean Land Specialization Program or U-Eco City project remains only to the stage of verification. Therefore, there are limitedness for realization of result technologies or sustainable operation & management of test-bed after projects finished. So, sustainable operation & management system and guideline of test-bed are necessary. Therefore, this study reviews the strengths and weaknesses of existing test-bed cases and intelligent security researches. After reviewing, the concept of a Intelligent Security Test-bed is established and appropriate test-bed selection criteria is also suggested. Based on objective criteria, selected test-bed can achieve sustainable management even after finishing the project and contribute the construction of standard model for citizen's safety.

This research suggests construction processes and security solutions for security control center as management measures for security management improvement in domestic electronic security companies. Security control center (SCC) is the central nerve of electronic security service, and no matter how well the on-site response system has been built, if SCC ceases to work due to an incident or disaster or security control personnel are harmed, the electronic security system cannot perform its proper functions. It is divided to a spatial structure, the infrastructure, control equipment, control solutions and operating structure in a construction process in the security control center. And a solution can be presented for physical security, information security, and personnel security in the way to security solutions.

The emergences of GeoSensor and researches about GIS have promoted many researches of u-GIS. The disaster application coupled in the u-GIS can apply to monitor accident area and to prevent spread of accident. The application needs the u-GIS DSMS technique to acquire, to process GeoSensor data and to integrate them with GIS data. The u-GIS DSMS must process big and large-volume data stream such as spatial data and multimedia data. Due to the feature of the data stream, in u-GIS DSMS, query processing can be delayed. Moreover, as increasing the input rate of data in the area generating events, the network traffic is increased. To solve this problem, in this paper we describe TRIGGER ACTION clause in CQ on the u-GIS DSMS environment and proposes data source management. Data source weight table controls GES information and incoming data rate. It controls incoming data rate as increasing weight at GES of disaster area. Consequently, it can contribute query processing rate and accuracy

Recently, as the spatial information and various multimedia are fused together, the demand for the high value-added spatial information contents and the necessity of technology for spatial information security are increasing. However, since the current security policy is being managed independently by each system, there is a problem with unreliable or costly to modify or revise the security policy. Such problems occur frequently in the process of coordination or integration of the spatial information management systems that are used in public institutions and private companies. Therefore, in this paper, the access control system that could provide an integrated security policy for many spatial platforms and systems with expandable grammar and semantics was designed and implemented based on GeoXACML proposed by OGC. As the GeoXACML-based access control system designed and implemented in this paper follows the international standard specifications, it provides high portability and interoperability. Finally, in this paper, the efficiency of the system was proved by applying it to a virtual scenario on the military area requiring the access control.
