    The initial phase of the deployment of Vehicular Ad-Hoc Networks (VANETs) has begun and many research challenges still need to be addressed. Location privacy continues to be in the top of these challenges. Indeed, both of academia and industry agreed to apply the pseudonym changing approach as a solution to protect the location privacy of VANETs'users. However, due to the pseudonyms linking attack, a simple changing of pseudonym shown to be inefficient to provide the required protection. For this reason, many pseudonym changing strategies have been suggested to provide an effective pseudonym changing. Unfortunately, the development of an effective pseudonym changing strategy for VANETs is still an open issue. In this paper, we present a comprehensive survey and classification of pseudonym changing strategies. We then discuss and compare them with respect to some relevant criteria. Finally, we highlight some current researches, and open issues and give some future directions

    Emerging privacy challenges and approaches in CAV systems

    The growth of Internet-connected devices, Internet-enabled services and Internet of Things systems continues at a rapid pace, and their application to transport systems is heralded as game-changing. Numerous developing CAV (Connected and Autonomous Vehicle) functions, such as traffic planning, optimisation, management, safety-critical and cooperative autonomous driving applications, rely on data from various sources. The efficacy of these functions is highly dependent on the dimensionality, amount and accuracy of the data being shared. It holds, in general, that the greater the amount of data available, the greater the efficacy of the function. However, much of this data is privacy-sensitive, including personal, commercial and research data. Location data and its correlation with identity and temporal data can help infer other personal information, such as home/work locations, age, job, behavioural features, habits, social relationships. This work categorises the emerging privacy challenges and solutions for CAV systems and identifies the knowledge gap for future research, which will minimise and mitigate privacy concerns without hampering the efficacy of the functions

    BACK TO KATZ: REASONABLE EXPECTATION OF PRIVACY IN THE FACEBOOK AGE

    Part I of this Note discusses the evolution of Fourth Amendment jurisprudence in reaction to advancing technology, the Supreme Court and circuit courts’ disposition in dealing with electronic “beeper” tracking (the technology that predated GPS), and the legal doctrine governing the government’s use of cellular phones to conduct surveillance of individuals both retroactively and in real-time. Part II examines the developing split among the federal circuits and state courts over whether GPS surveillance of vehicles constitutes a search, as well as the parallel concerns raised in recent published opinions by magistrate judges as to whether government requests for cell-site information from third party service providers require a warrant. Part III of this Note argues for the adoption of a rule that GPS surveillance constitutes a search and seizure and should require a warrant because the privacy expectation—that the government is not tracking its citizens twenty-four hours per day—is still one that society considers legitimate. It also argues that increasing public use or consent to third party use of GPS technology does not destroy an individual’s reasonable expectation of privacy in his movements, nor indicate that society no longer views these expectations as reasonable. In fact, increased public awareness of recent technological invasions of privacy may be producing an increased demand for control over information

    A Framework for Integrating Transportation Into Smart Cities

    In recent years, economic, environmental, and political forces have quickly given rise to “Smart Cities” -- an array of strategies that can transform transportation in cities. Using a multi-method approach to research and develop a framework for smart cities, this study provides a framework that can be employed to: Understand what a smart city is and how to replicate smart city successes; The role of pilot projects, metrics, and evaluations to test, implement, and replicate strategies; and Understand the role of shared micromobility, big data, and other key issues impacting communities. This research provides recommendations for policy and professional practice as it relates to integrating transportation into smart cities
