In accordance with some embodiments, an apparatus that enables trusted location tracking includes a housing arranged to hold a user equipment, one or more devices, a local communication device, and a controller at least partially supported by the housing. The apparatus obtains, via the one or more devices, a first set of data characterizing a location of the user equipment. The apparatus further establishes, via the location communication device, a local communication channel with the user equipment. The apparatus also obtains through the local communication channel a second set of data characterizing the location of the user equipment. The apparatus also determines a trust score characterizing the second set of data based on the first set of data. The apparatus additionally triggers an alert in accordance with a determination that the trust score is below a threshold.

A method and system for detecting if a relay is present in a PEPS system for a vehicle is provided which includes (a) transmitting LF signals from antennas associated with a vehicle to a key fob using a 3D LF receiver to measure the LF signal level on the x, y and z-axes; (b) selecting two or more parallel antennas associated with the vehicle that are orthogonal to the antenna at the PEPS triggering location; (c) normalizing the x, y and z vectors that are measured by the key fob for the selected two or more parallel antennas associated with the vehicle; and (d) determining if the normalized x, y and z vectors for the selected two or more parallel antennas associated with the vehicle are within a predefined range.

Methods and devices for privately verifying and enhancing location data by a distributed ledger system are disclosed. A location-based services server receives a possible location of a mobile device. A location verification system determines a detected location of the mobile device. A distributed ledger system uses a private set intersection technique to determine whether the possible location corresponds to the detected location without the possible location or detected location being shared. Probabilities associated with the possible and detected locations can also be combined to enhance the accuracy of the possible location.

The exemplary embodiments of the present disclosure provide a method and an apparatus for detecting an abnormal roaming request which acquires information of user equipment which sends a roaming request message, calculates a risk of the roaming request message using a roaming request location and a roaming request time of the user equipment, and safely processes the request according to the risk.
