Claim of US Patent No. 10,069,793

1. An identity verification method, adapted for an internet of things (IoT) gateway device, comprising:establishing a look-up table comprising a valid media access control (MAC) address list and a valid receiver signal strength indicator (RSSI) range of at least one valid client device by an IoT gateway device;
receiving connection request sent from at least one client device by the IoT gateway device, wherein the connection request comprises a MAC address of the client device;
obtaining the MAC address and a RSSI value of the client device by the IoT gateway device according to the connection request;
comparing the MAC address and the RSSI value of the client device with the valid MAC address list and the valid RSSI range by the IoT gateway device;
determining the client device is the valid client device by the IoT gateway device if the MAC address is determined to be the valid MAC address and the RSSI value falls within the valid RSSI range;
if the client device is the valid client device, establishing a wireless connection by the IoT gateway device; and
if the client device is not the valid client device, rejecting the connection request and blocking the client device by the IoT gateway device.
