  • Publication number: 20250193031
    Abstract: The present invention discloses a method for private set intersection in a smart city system, a device, and a storage medium. According to the present invention, a threshold secret sharing technology is adopted to share a private set among three parties, so that an intersection cardinality is hidden and security of private set intersection is improved. Before two parties perform the private set intersection, a blockchain is used to verify identities of the two parties, which protects security of data of the two parties to a certain extent. In addition, according to the present invention, the private set is divided into a plurality of subsets with labels, which implements an interaction manner with finer granularity. Therefore, compared with a private set intersection solution in a previous smart city system, the present invention is greatly improved in practicability, security, and other aspects.
