[0030] The present invention and its effects will be further described below in conjunction with the accompanying drawings.
[0031] like figure 1 As shown, the system model of the present invention consists of three entities: terminal equipment, edge nodes and cloud servers. These systems are described as follows:
[0032] (1) Terminal device: The user's terminal device collects wireless signal strength RSSI data from multiple wireless sensor beacons in indoor areas (eg, shopping malls, underground parking lots, exhibition halls, etc.). In order to solve the problem of privacy leakage, the terminal device first independently performs privacy protection processing on the original RSSI data that satisfies differential privacy, and then sends the processed data to nearby edge nodes, where multi-user data aggregation is performed. End devices are considered trusted in this model.
[0033] (2) Edge nodes: Edge nodes are some intelligent gateways with data computing and storage ...
