US 11,240,659 B2 · Privacy protection mechanisms for connected vehicles

Abstract

Various embodiments are generally directed to techniques for providing improved privacy protection against vehicle tracking for connected vehicles of a vehicular network. For example, at least one road side unit may: identify a set of vehicles that require pseudonym changes and send an invitation for a pseudonym change event to each of the vehicles, determine at least a total number of the acceptances, determine whether the total number meets or exceeds a predetermined threshold number, send acknowledgement messages to the accepting vehicles if the threshold number is met, and form a vehicle group to coordinate the pseudonym change event during a privacy period. During the privacy period, the RSU and the vehicles may communicate with each other in a confidential and private manner via key-session-based unicast transmission, and coordinate transmission power and vehicle trajectory adjustments to maximize the benefits for safety and obfuscation for privacy.

Dependent claims

An apparatus, comprising:

memory to store instructions;
and
processing circuitry, coupled to the memory, operable to execute the instructions, that when executed, cause the processing circuitry to:
identify a set of vehicles that require pseudonym changes;
send an invitation for a pseudonym change event to each of the identified vehicles, wherein the invitation includes at least a location and a time for the pseudonym change event;
determine which of the vehicles respond with an acceptance to the invitation and a total number of acceptances;
determine whether the total number of acceptances meets or exceeds a predetermined threshold acceptance number;
send acknowledgement (ACK) messages to the accepting vehicles if the total number of acceptances meets or exceeds the predetermined threshold acceptance number;
form a vehicle group, the vehicle group including at least the accepting vehicles;
and
coordinate, for vehicles in the vehicle group, the pseudonym change event during a privacy period.

8 more elements

A system, comprising:

first processing circuitry, coupled to memory, operable to execute instructions, that when executed, cause the first processing circuitry to:
identify a set of vehicles that require pseudonym changes;
send an invitation for a pseudonym change event to each of the identified vehicles, wherein the invitation includes at least a location and a time for the pseudonym change event;
determine which vehicles respond with an acceptance to the invitation and a total number of acceptances;
determine whether the total number of acceptances meets or exceeds a predetermined threshold acceptance number;
send acknowledgement (ACK) messages to the accepting vehicles if the total number of acceptances meets or exceeds the predetermined threshold acceptance number;
form a vehicle group, the vehicle group including the accepting vehicles;
and
coordinate, for vehicles in the vehicle group, the pseudonym change event during a privacy period.

6 more elements

At least one non-transitory machine-readable storage medium comprising instructions that when executed by at least one processor, causes the at least one processor to:

identify a set of vehicles that require pseudonym changes;
send an invitation for a pseudonym change event to each of the identified vehicles, wherein the invitation includes at least a location and a time for the pseudonym change event;
determine which vehicles respond with an acceptance to the invitation and a total number of acceptances;
determine whether the total number of acceptances meets or exceeds a predetermined threshold acceptance number;
send acknowledgement (ACK) messages to the accepting vehicles if the total number of acceptances meets or exceeds the predetermined threshold acceptance number;
form a vehicle group, the vehicle group including the accepting vehicles;
and
coordinate, for vehicles in the vehicle group, the pseudonym change event during a privacy period.
