Researchers have developed a new framework to evaluate the utility of synthetic trajectory generators, which are used to protect privacy in human mobility data. The study highlights that while these generative models offer a promising approach to balancing privacy and utility, privacy evaluation remains a significant challenge. The paper proposes an adversarial evaluation method, including a new membership inference attack, to address these privacy concerns, especially in light of EU regulations. AI
