| Summary: | 碩士 === 長庚大學 === 資訊管理學研究所 === 96 === More and more obvious applications rely on the Location-Based Services (LBS) that offer highly personalized services to the subscriber based on their current position using the Global Positioning System (GPS) [2] and Wireless Communications. Generally, the LBS track the position of users on the network while inside the facility, and then collect this position information for the users, such as information on restaurants and stores, police stations, gas stations, hospitals, etc. When the exchange of details of service is done via an untrusted telecommunications company (TC), the privacy of the user could be in jeopardy.
In this work, we propose a new scheme for user privacy in the LBS, which does not rely on a trusted TC between the user and service provider. We believe that the scheme in the LBS will provide better privacy and security for the users.
