  • Patent number: 12381724
    Abstract: The present disclosure provides a data maximum/minimum value (max/min) aggregation method and system for privacy protection. A Paillier cryptosystem is used to encrypt user data, so as to protect privacy and security of user health data. Further, time aggregation is implemented to help a control center obtain an overall health condition of a client in one aggregation period. By using a homomorphic property of the Paillier cryptosystem, the present disclosure implements aggregation of a max/min of privacy protection, and helps the control center obtain a max or a min of health data of the client in the aggregation period.

  • 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.

  • Patent number: 11631408
    Abstract: The present disclosure provides a method for controlling data, a device for controlling data, an electronic equipment, and a storage medium. The method for controlling data includes receiving a first voice signal for a virtual object displayed on a first electronic device collected by the first electronic device; obtaining a first recognition result by parsing and recognizing the first voice signal; generating, based on the first recognition result, a control instruction for controlling the virtual object to perform an action corresponding to the control instruction; and sending the control instruction to the first electronic device and at least one second electronic device in the same virtual space. The disclosure is capable of controlling a process of the virtual object performing a live streaming interaction by using a voice interaction mode, thus reducing user operations and improving user experience.
