SPOT: Secure and Privacy-preserving prOximiTy protocol for e-healthcare systems. (arXiv:2212.00381v1 [cs.CR])

This paper introduces SPOT, a Secure and Privacy-preserving prOximity based
protocol for e-healthcare systems. It relies on a distributed proxy-based
approach to preserve users' privacy and a semi-trusted computing server to
ensure data consistency and integrity. The proposed protocol ensures a balance
between security, privacy and scalability. As far as we know, in terms of
security, SPOT is the first one to prevent malicious users from colluding and
generating false positives. In terms of privacy, SPOT supports both anonymity
