KUR-Algorithm: From Position to Trajectory Privacy Protection in Location-Based Applications
Sprache des Titels:
Database and Expert Systems Applications
Some obfuscation techniques may fail to protect user privacy because of the moving context as well as the background knowledge of adversaries. In this paper, we propose a novel scheme to distinctly protect user privacy not only from user position but also from user trajectory. Furthermore, we present kUR-algorithm, which is context-aware and can be employed as either an independent method or a supportive technique, to give the high-level user privacy protection against privacy disclosure and privacy leak. Last but not least, we analyse other potential privacy problems which usually emerge as outliers and show how well our proposed solution overcomes these scenarios.
