Patent number: 11407423Abstract: Systems, apparatus, methods, and techniques for an ego vehicle to respond to detecting misbehaving information from remote vehicles are provided. An ego vehicle, in addition to reporting misbehaving vehicles to a misbehavior authority via a vehicle-to-anything communication network, can, take additional actions based in part on how confident the ego vehicle is about the evidence of misbehavior. Where the confidence is high the ego vehicle can simply discard the misbehaving data and provide an alternative estimate for such data from alternative sources. Where the confidence is not high the ego vehicle can request assistance from neighboring vehicles and roadside units to provide independent estimates of the data to increase confidence in the evidence of misbehavior.Type: GrantFiled: December 26, 2019Date of Patent: August 9, 2022Assignee: INTEL CORPORATIONInventors: Xiruo Liu, Liuyang Yang, Manoj Sastry, Marcio Juliato, Shabbir Ahmed, Christopher Gutierrez

Publication number: 20220174479Abstract: 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.Type: ApplicationFiled: December 10, 2021Publication date: June 2, 2022Applicant: INTEL CORPORATIONInventors: Xiruo LIU, Shabbir AHMED, Ralf GRAEFE, Christopher GUTIERREZ, Marcio JULIATO, Rafael ROSALES, Manoj SASTRY, Liuyang YANG
