Location Based Service(LBS) is various and widely spreading service based on the Location information. Those services are under the control of Privacy Act for Location Information to protect from misusing or overusing of personal location information. In this paper, we analyze a concept and a feature of personal location information and how to use and control the flow of location information by the Location Information Act. As the result of this paper, we expect to use the location information in various fields to develop more efficient service.

This paper proposes a model for the location information grading policy. Location information grading policy is that government would give a public notice of criterion for location information quality, and location information operators should elucidate the grade of provided location information. As the quality grade of services is provided in the 'terms of use' with the detailed quality specification and quality range, the user can understand the quality of location information, and can select more suitable service for their purposes. Additionally, the qualiy grading policy can enforce the location information operators and location service providers to support more stable and reliable service quality. In this paper, we propose the model of location information grades, the typical classification of quality, and the realitic policy applying model. Recent enacted 'Location Information Law' are expected to activate korean information market. In this situation, proposed location information grading policy take a role in protecting location privacy and improving the reliability of location information services.

The Location Based Services comprised GIS and Telecommunication allow users to receive various services based on their geographic location. It is need to legislation to encourage the provision and use of location information by providing privacy protection to users. But the contents of the legislation proposed by Korean government have problems conflicted between protection of a person's location information and invigoration of location-based services. The purpose of this study is to search complementary measures for privacy protection of location information from a viewpoint of effective management strategy for geographic information.

It is essential to ensure public use of and privacy of location information for promoting the location based services. The grade designation for location information is required to accomplish them. The grade designation for location information can increase the reliability of location information and reinforce the right of choice for user. Therefore the institution of grade designation for location information should be introduced rapidly to keep up with the growth of the location based services industry.

Location Information is an information about a place where an individual exists or had existed. As smart phones are popularized, location information becomes more than simple information about the place. As a result, services using an individual's location information became the trend. However, problems arising from discharging Private Information can damage an individual, because it causes financial and economic loss but also detects individual's location and route directly. In realities, the guide that regulates Location Based Service for administering Private Location Information is insufficient. Therefore, this paper proposes check items, which contain standards of judicial action, financial loss ratings, importance of Private Location Information, and criticality of check lists, during the Private Location Information audit at the level of analysis, design, and management of the Information System, in order to prevent the infringement and disclosure of the Private Location Information. Moreover, the proposed check items were verified for its suitability by the professionals' survey.

As the mobile device and broadband wireless internet such as WiBro, HSDPA is widely spreading, various types of advertisement and services based on personal location information can be provided. However, with convenience supported by these services, it is possible to be increased an invasion of privacy such as personal location and moving pattern. In this paper, we analysis an essential element for protection of privacy related on location information in mobile environment and propose location privacy protocol for managing location privacy self-control. And we design and implementation prototype of location privacy self-control system which is able to manage user's location privacy condition oneself using the proposed location privacy protocol.

Currently, various kinds of contents using smart phone's location information are developed and provided to users. The market size of the location-based service industry utilizing location information is also increasing every year and the majority of smart phone users occupy university students and most of the university students are using their owns smart phones, and they are the biggest users of location-based services and the main target of location information collection. In this paper, we conduct to a survey how university students understand about location information. Based on the results of the survey, we will deeply examine which one is needed to improve understanding of university students' location information collection and usage and what should be considered for the development of the location-based service industry and education of location information and then we propose some helpful suggestion.

There are wireless location acquisition technique, LBS platform technique, and LBS application technique in the important technical elements of the LBS. In this paper, we design a location data management system which is the core base technique of the important technical elements of the LBS. The proposed system consist of an application interface of LBS, a query processor of application. service, a location estimator of the moving objects, a location information manager, a real-time data receiver, and a database of location data. This system manages efficiently the location change information of the moving objects using the database technique, suggests some useful inform to the users of LBS, and supports operation and facility of location estimation to process continuous location data of the moving objects. On the basis of location data triggering, this system supplements the problem of the related location data management systems to complement the loss of location data in the environment of real-time.

Location Based Service (LBS) is a service provided to the subscribers based on their (or others') geographical location. Interest in LBS has increased not only in the aspect of promoting utilization, including the public usage such as emergency rescue, but also in the aspect of protecting the personal location information of the subscribers. This study aims to suggest and classify the business models for LBS services, focusing on the flow of the personal location information. Each business model is reviewed from the perspective of protecting the location privacy of the subscribers.

This paper proposes the location acquisition methods and LBS(location-based services) system using RFID(radio frequency identification) tags with location information in ubiquitous city. Location information is checked using RFID tags attached to various buildings. stores and road signs. And various LBSs are provided based on the location information. Traditionally, when the location information is obtained by a GPS, the precision of the location information may deteriorate due to geographical displacement of a satellite and GPS receivers, for example shadow zone by building, in-door environment, and heavy cloud. The objective of this paper is to provide a ULID(universal location identification) data structure, a ULID-based location acquisition method and an LBS system, in which precise location information is extracted using RFID tags attached to various buildings, stores and road signs and ULID and also danger of information leakage is minimized so that an LBS of ubiquitous environment can be provided to a user.
