Recent development in wireless communication technology like GPS as well as mobile equipments like PDA and cellular phone makes location-based services (LBSs) popular. However, because users request a query to LBS servers by using their exact locations while moving on the road network, users' privacy may not be protected in the LBSs. Therefore, a mechanism for users' privacy protection is required for the safe and comfortable use of LBSs by mobile users. For this, we, in this paper, propose a road network distance based cloaking scheme supporting user privacy protection in location-based services. The proposed scheme creates a cloaking area by considering road network distance, in order to support the efficient and safe LBSs on the road network. Finally, we show from our performance analysis that our cloaking scheme outperforms the existing cloaking scheme in terms of cloaking area and service time.

The Personal Information Protection Commission was launched in August 2020 as an integrated control tower for personal information protection, but several problems have been pointed out in the personal information protection operation system. First, despite the fact that Korea's personal information protection system has an integrated legal system that regulates both the public and private sectors, it has been pointed out that it is difficult to carry out smooth personal information protection functions due to incomplete integration of protection functions, such as the Financial Services Commission being in charge of personal credit information protection and the Korea Communications Commission being in charge of personal location information protection. Next, despite the increasing number of public sector personal information leakage incidents, there is a lack of personnel with expertise and specialized support organizations to efficiently investigate them, and there is a concern that the lack of an efficient response system to personal information infringement by global IT companies in Korea in the era of digital commerce may weaken the protection of citizens' personal information. In order to solve these problems, I reviewed overseas cases and literature and proposed the following measures. First, it is necessary to centralize the personal information protection supervision function for credit information and location information to the Personal Information Protection Commission. Second, it is necessary to secure expertise by securing specialized personnel and establishing specialized institutions to respond to public sector personal information leakage incidents. Third, it is necessary to revitalize the domestic agency designation system and establish an international cooperation system to protect people's personal information in the digital commerce era. I believe that these measures to develop the personal information protection system will lead to more systematic personal information protection.

Recently, NFC technology of short-range wireless communication using a smart phone to perform personal authentication with the electronic payment has been in the spotlight in various fields. However, the security associated with the personal information and the location information is vulnerable because it is easily fused with the existing mobile services and devices. In this paper, we propose a model for NFC payments help protect personal information and location information of NFC payment systems and services in various fields. Proposed model uses tag-based services in order to protect personal information and position information. The proposed model using the tag-based services is the place to check the various features available information in a simple Tag that can be easily accessed.

In Location-Based Service (LBS), a scheme to hide the exact locations of users is required for privacy protection, In this paper, we propose a grid-based cloaking method considering K-anonymity and L-diversity. For this, our method creates a minimum cloaking region by finding L number of buildings (L-diversity) and then finding number of users (K-anonymity). Especially, we use a effective filtering method for generating the minimum cloaking region in a fast way. Finally, we show from a performance analysis that our cloaking method outperforms the existing method, in terms of query processing time based on the size of cloaking regions.

A location information used in LBS provides convenience to the user, but service provider can be exploited depending on how much risk you have. Location information can be exploited to track the location of the personal privacy of individuals because of the misuse of location information may violate the user can import a lot of damage. In this paper, we classify the life cycle of location information as collection, use, delivery, storage and destroy and analyze the factors the privacy is violated. Furthermore, we analyze information security mechanism is classified as operation mechanism and policy/management mechanism and propose a security solutions of all phase in life cycle.

This thesis analyzes the Apple Inc.'s case from the viewpoint of the necessity for the protection of information privacy related to location data as for information society and ubiquitous community. Meanwhile, the regulatory conformity to equilibrium of contradictional value between personal data protection and utilization of information is debated from the fundamental right as for constitutional law concept to the commercial and technological structure in terms of economic and business point. Therefore, this paper reaches the conclusion that the legislative system should form a harmonious relationship between legal protection and lawful utilization to reappraise the present condition of legalization on personal data protection from guaranteeing rights and interests of information subject in the perspective of human rights to information guarantee consequently. As a result, it is required to revaluate the lawfulness of the fine on the violation of administrative duty levied by KCC(Korea Communications Commission).

이 프로젝트는 사용자의 위치 기록을 안전하게 기록 및 관리할 수 있는 앱으로, 사용자 기기의 로컬 데이터베이스를 활용하여 위치 정보에 관한 개인정보 보호 측면을 강화한다. 해당 앱은 사용자가 원할 때 기록 기록을 시작하고 종료할 수 있으며, 기기 내에 저장된 사진의 위치정보와 연동하여 이동경로와 기록 시간대에 맞는 사진을 한 눈에 볼 수 있다. 이 프로젝트는 구글 맵의 타임라인과 비슷하지만, 사용자의 위치 정보를 스스로 제어할 수 있는 부분에서 차별성이 존재한다.

본 논문에서는 사용자 위치 기반의 푸시 메시지 전달 기법을 제안한다. 제안한 기법은 푸시 메시지에 메시지 전달이 필요한 범위 정보를 내포하여, 메시지를 수신하는 모바일 장치가 사용자 위치에 기반을 두어 수신된 메시지가 적절한 메시지인지 판단한 후 디스플레이를 결정한다. 사용자 위치 기반의 푸시 메시지는 기존 사용자의 위치를 서버에 등록할 필요 없이 모바일 장치에서 사용자 위치를 판단함으로서 개인 정보를 보호하고 푸시 메시지를 사용자 위치에 기반하여 효과적으로 전달할 수 있다. 제안 기법의 응용 예로서는 위치기반 서비스 및 사용자 맞춤형 광고 서비스 등이 있다.

위치기반 서비스에 관련된 기술 연구가 활발히 진행됨에 따라 다수의 사용자가 위치기반 앱 서비스를 이용하고 있다. 그러나 위치기반 앱 서비스를 이용하는 사용자가 점차 증가함에 따라 사용자의 위치정보가 노출될 확률이 높아지고 있다. 우리는 개인의 위치 정보를 보호하면서도 서버의 작업 부하를 줄일 수 있는 self-Privacy Protection Range (self-PR)을 제안한다. Self-PR은 클라이언트의 조건(ex. 배터리 상태, 모바일 기기의 성능 등)에 따라 보호 영역을 설정할 수 있기 때문에 이상적인 질의처리가 가능하다. 반면에 서버는 클라이언트의 self-PR이 증가할수록 서버는 데이터 탐색 경로가 짧아지기 때문에 작업부하를 줄일 수 있다. 그리고 서버는 클라이언트의 self-PR 확인하고 질의 결과를 전송하기 때문에 정확한 질의 결과를 전송할 수 있다.
