Location Cheating: A Security Challenge to Location-based Social Network Services
Wenbo He, Xue Liu, Mai Ren

TL;DR
This paper investigates the security vulnerabilities of location-based social networks like Foursquare, demonstrating how attackers can cheat location verification at scale and discussing potential defenses to prevent such attacks.
Contribution
It introduces a novel location cheating attack that bypasses existing verification mechanisms and analyzes large-scale cheating possibilities using real-world data from Foursquare.
Findings
Automated large-scale location cheating is feasible.
Current verification mechanisms can be easily bypassed.
Insights into potential defense strategies are provided.
Abstract
Location-based mobile social network services such as foursquare and Gowalla have grown exponentially over the past several years. These location-based services utilize the geographical position to enrich user experiences in a variety of contexts, including location-based searching and location-based mobile advertising. To attract more users, the location-based mobile social network services provide real-world rewards to the user, when a user checks in at a certain venue or location. This gives incentives for users to cheat on their locations. In this report, we investigate the threat of location cheating attacks, find the root cause of the vulnerability, and outline the possible defending mechanisms. We use foursquare as an example to introduce a novel location cheating attack, which can easily pass the current location verification mechanism (e.g., cheater code of foursquare). We also…
