Location leakage in distance bounding: Why location privacy does not work
In many cases, we can only have access to a service by proving we are sufficiently close to a particular location (e.g., in automobile or building access control). In these cases, proximity can be guaranteed through signal attenuation. However, by using additional transmitters an attacker can relay signals between the prover and the verifier. Distance-bounding protocols are the main countermeas...
متن کاملQuantifying Location Privacy Leakage from Transaction Prices
Large-scale datasets of consumer behavior might revolutionize the way we gain competitive advantages and increase our knowledge in the respective domains. At the same time, valuable datasets pose potential privacy risks that are difficult to foresee. In this paper we study the impact that the prices from consumers’ purchase histories have on the consumers’ location privacy. We show that using a...
متن کاملLocation Depersonalization for Location Privacy Protection in Location-Based Services
A spatial region with K different footprints indicates that it has been visited by K different people. An adversary may be able to identify all these users, but will not know who was there at what time. This observation gives us a new direction to investigate location depersonalization in location-based services (LBSs). We propose to leverage users’ historical location samples, each being a foo...
متن کاملLocation Privacy in Bluetooth
We discuss ways to enhance the location privacy of Bluetooth. The principal weakness of Bluetooth with respect to location privacy lies in its disclosure of a device’s permanent identifier, which makes location tracking easy. Bluetooth’s permanent identifier is often disclosed and it is also tightly integrated into lower layers of the Bluetooth stack, and hence susceptible to leakage. We survey...
