Shadaab Siddiqie and Anirban Mondal working under the supervision of Prof. P Krishna Reddy presented a paper on An improved dummy generation approach for enhancing user location privacy at the 26th International Conference on Database Systems for Advanced Applications (DASFAA 2021), Taipei, Taiwan. The event was held online from 11 – 14 April.
Research work as explained by the authors: Location-based services (LBS), which provide personalized and timely information, entail privacy concerns such as unwanted leaks of current user locations to potential stalkers. Existing works have proposed dummy generation techniques by creating a cloaking region (CR) such that the user’s location is at a fixed distance from the center of CR. Hence, if the adversary somehow knows the location of the center of CR, the user’s location would be vulnerable to attack. We propose an improved dummy generation approach for facilitating improved location privacy for mobile users. Our performance study demonstrates that our proposed approach is indeed effective in improving user location privacy.
The International Conference on Database Systems for Advanced Applications DASFAA provided a leading international forum for discussing the latest research on database systems and advanced applications. DASFAA is a well-established international conference series that provides a forum for technical presentations and discussions among database researchers, developers, and users from academia, business, and industry, which showcases state-of-the-art R&D activities in the general areas of database systems, Web information systems, and their applications. The conference’s long history has established the event as the premier research conference in the database area.
