GeoSecure-B:A Method for Secure Bearing Calculation

Location-Based Services (LBS) applications are everywhere these days. Detecting the heading or bearing is crucial for many of these applications, as it indicates the direction the user is moving. This information is typically derived from the GPS trajectory of the user. However, because GPS data can reveal sensitive information, such as a user's location, there are privacy concerns associated with its use. Therefore, there's a need to devise a solution that safeguards GPS data from potential adversaries. Although multiple techniques for calculating bearing are documented in the literature, this paper presents a secure method, called GeoSecure- B,for calculating bearing based on GPS coordinates while preserving user location privacy. Our methodology is assessed using Microsoft's GeoLife dataset, demonstrating that our results closely align with bearings calculated from methodologies utilizing real GPS coordinates.
