스마트폰의 확산과 위치정보를 활용한 다양한 서비스가 확대됨에 따라 전 세계적으로 위치기반서비스(LBS) 시장이 활성화 되고있다. 하지만, 개인 위치정보 침해사례에 대한 논란이 증가하고 있어 이에 따라 규제 정비에 대한 관심도 높아지고 있다. 위치정보 규제는 이용자의 개인정보와 프라이버시를 보호할 수 있으나, 다양한 서비스의 개발과 산업 활성화 측면에서 부정적인 영향을 끼칠 수 있다는 양면성이 있다. 특히 우리나라는 전 세계적으로 유일하게 위치정보 관련 독립적인 '위치정보보호법'을 제정하여 높은 위치 정보 규제를 적용하고 있어 LBS 산업이 활성화 되지 못하고 있다는 지적과 산업 활성화를 위한 규제 완화가 필요하다는 비판이 지속적으로 제기되고 있다. 국내외 LBS 시장 성장과 관련 규제를 비교 분석하여 LBS의 규제가 산업 활성화와 음(-)의 관계 즉, 규제가 강화 될수록 시장 진입 및 사업 활동에 제약이 있음을 확인하였으며, 또한 프라이버시와 직접적인 관련이 없는 규제를 완화함으로써 LBS 산업을 활성화 할 수 있음을 확인하였다.

Recently, location based service(LBS) expended based on personal specialized service, however since commercialized GPS based emergency rescue service comes with shadow zone for GPS signal such as inside building, the accuracy and reliability are not guaranteed. Therefore to improve such problem, we propose an active location detecting algorithm using RFID-TAG and Yagiantenna. To track the location of RFID-TAG where signal is generated, location tracking device in which Yagi-Antenna is installed moves around. Since directed wave and reflected wave co-exist during signal reception, final signal generated location is searched by setting up multiple of locations where signal can be generated on the map and moving location tracking device along minimum length of path. The algorithm proposed in this paper was verified of its technical validity through simulator.

LBS must manage various context data and make the best use of this data for application service in ubiquitous environment. Conventional mobile object data management architecture did not consider process of context data. Therefore a new mobile data management framework is needed to process location context data. In this paper, we design a new context management framework for a location based application service. A suggestion framework is consisted of context collector, context manager, rule base, inference engine, and mobile object context database. It describes a form of rule base and a movement process of inference engine that are based on location based application scenario. It also presents an embodiment instance of interface which suggested framework is applied to location context interference of mobile object.

The spread of wireless Internet technology development and applications with location information in the form of location-based services are more varied. In particular, where you recognize the location of objects such as people and things, and to provide valuable services based on ubiquitous, location-based services (Ubiquitous Location Based Services: u-LBS) is emerging as an important service. In this paper precise location data to the car crash through the location and offers related service system. In this paper the precise location tracking proposed by the concept of the Rail, road, to extract the location Data Matching Data and the current location is obtained. System used in GPS Packet and information about the location of the vehicle collision and the collision time, the vehicle consists of NodeID is about. Using these data, a packet is to be created when the conflict between vehicles in the vehicle will be sent to Gateway. Gateway to the packets that were sent from the Server to determine whether the conflict is that in an emergency situation, Emergency Center for location information and let me know whether or not the conflict will be measured. Also, for those on the outside of an emergency such as a family related to the wireless terminal wireless (PDA, cell phone) is to let me know. Server get into the conflict that was configured to store information on the Database. Additionally, the proposed u-LBS system to verify the validity of the experiment was performed.

Recently, spread of large amount Smartphones made users to download location-based service applications, which provided by application developers. These location-based service applications are convenient tool for users. Location-based service use technology to find location of user and provide information of user's location. Leakage of information of user's location and expose of privacy life raised new controversy. In this thesis, it will analyze relations of increase of Smartphone market, usage of Location-based service and severity of personal information leakage. Also, it will analyze examples of user's case of damage which caused by leakage personal information and find solutions to reduce damage of personal information leakage. In research, it will find cases of damage that cause by Location-based service. Also it will analyze and research cases of damage and present with graph and chart. In conclusion, to reduce and prevent from damage which caused by leakage personal information, it is important that users and application developers to realize danger of private and personal information leakage. Also, user's personal information must deal with cautiously and application developers have to research and develop the application with powerful security.

Recently, in according as rapid improvement of telecommunication markets and wireless internet technology, Location- Based Services (LBS) have been discussed as new 'Killer' application. The purpose of LBS is to determine location of user through mobile handset and to offer location information service to end-user. This paper has suggested an efficient transmission scheme of maps data as one of the important content services relating to data transmission of LBS in mobile environment. The basic system consists of three parts : (1) GIS (Geographic Information System) Server for storing, processing and handling map data, (2) Middleware Server for transmitting of map data by request of client, and (3) Client for requesting map data to Server and displaying them on handset. Also, in order to transmit map data, we are to expand WKB (Well Known Binary) in conformance to Simple Feature Specification of OGC (Open GIS Consortium), and increase efficiency of data transmission by developing trans mission data format to be able to transmit lightweight data and considering data compression technology.

Location Based Service (LBS) provides high-value added service to users and various works about IBS have been actively performed. The core technology or LBS is positioning of the users. In the field of positioning, outdoor positioning and indoor positioning are developed separately. We are proposing a design of an outdoor-indoor positioning system, implementing a prototype of the system, and verifying the usefulness of the system through experiments. Our experimental results shows that the average error of our system is 4.8 m in the case of out-door positioning and it is 3.3 m in the case of in-door positioning.

최근 수많은 모바일 어플리케이션이 개발되고 있는 가운데 위치기반 서비스(Location Based Service)를 이용하여 위치정보를 제공하는 어플리케이션들이 인기를 얻고 있다. 예를 들어 스마트폰은 기기 안에 장착된 GPS 칩을 이용하여 프로그램을 실행 시키는 것만으로 나의 위치를 찾을 수 있고 목적지의 위치를 쉽게 찾을 수 있다. 하지만 이러한 기존의 위치정보제공 어플리케이션은 기본적으로 사용자 개인 한명의 위치만 파악할 수 있으며 현재 위치에서 목적지 위치까지의 정확한 방향을 찾을 수 없다. 본 논문에서는 이러한 기존의 LBS를 이용하여 위치정보를 제공하는 어플리케이션의 문제점을 개선한 모바일 어플리케이션 시스템 개발 사례를 제안한다. 제안하는 시스템은 증강현실(AR: Augment Reality)을 이용하여 방향을 찾을 수 있도록 하였으며 다중 사용자간의 위치정보를 공유할 수 있도록 함으로써 일상생활에서 사람과 약속을 하고 서로의 위치가 엇갈려서 만나는데 어려움을 겪게 되는 경우 매우 효율적일 것이라 사료된다.
