This problematic emerged with the advent of different safety-achieving techniques provided by IoV applications. There exist many techniques that cope with the identity and location privacy problem but while sacrificing safety. In our thesis, we focus on the solutions that are based on the pseudonymity concept and many techniques related to this category were proposed. With this said, we provide a comprehensive survey that deals with the aforementioned problem. then, we propose three techniques that ensure high level of location privacy while considering road-safety as an objective. The obtained results show that road-safety can still be achieved in conjunction with location privacy while using our techniques.enIoV, VANET, identity and location privacy, road-safety, location tracking, pseudonym changing, silent period, transmission range changing techniques.IoV, VANET, confidentialité de l’identité et de l’emplacement, sécurité routière, suivi de l’emplacement, changement de pseudonyme, période de silence, techniques de changement de portée de transmission.Thesis
