[0053] Example 1
[0054] figure 1 An application architecture of an IOT device secure access method based on the RFID signal provided by the present invention. like figure 1 As shown, the IOT device security access method provided by the present invention relates to a security device group, to be connected to the device, a security terminal, and an RFID reader.
[0055] The basic idea of the IOT device security access method provided by the present invention is, by recording the user's activity habits and user-defined access actions, training the CNN-LightGBM model that can be identified through the RF signal change. When the RFID signal to be accessing the device generates a signal fluctuation that is sufficiently high enough for the respective motion of the probability of prediction probability, it is considered to access the device to be accessed in the room. Since the RFID signal penetrates the outer wall of the room, there is a huge attenuation, so the change in the RFID ...

[0088] Example 2
[0089] image 3 An application example schematic diagram of an IOT device security access method provided by the present invention. In this embodiment, the safety terminal is a smart gateway for all IOT equipment in the room, including smart TV, smart speakers, and smart table lamps in the room, and ordinary devices include printers, to access devices for a smart sweeping robot. The RFID reader is a normal RFID reader. Among them, the smart gateway provides Wi-Fi hotspots as an AP end. The original smart TV in the room, the smart speaker and the smart desk lamp are connected by Wi-Fi, and the smart sweeping robot is used as the access device to be taken into the room. Smart TV, smart speakers, smart table lamps and smart sweeping machines include RFID tags. The user's behavior mode database has been established. The CNN-LightGBM model that can be identifiable will have been well trained. The user-defined action is stringing up and down three times. The specific ...
