Abstract
The present invention relates to an IoT control switch and method based on fingerprint identification permission control, comprising performing user identity and permission verification through fingerprint identification, implementing a MAC layer connectionless communication mechanism between a wire-free fingerprint Wi-Fi IoT switch and a standard Wi-Fi IoT device, and carrying control information for controlling the Wi-Fi IoT device by a privately defined control information element in a unicast packet or broadcast packet without requiring a MAC layer connection; the invention requires little modification, is cost effective to implement, and the data type, manner of acknowledgement, manner of encryption, and different fingerprint security control modes may be freely combined with each other, thereby providing wide applicability. The wire-free fingerprint Wi-Fi IoT switch may complete the translation of control information to the standard Wi-Fi IoT device by sending least number of packets, so as to realize low power consumption control. The wire-free fingerprint Wi-Fi IoT switch may also connect to an internet server via a Wi-Fi access point to perform update and upgrade of firmware, fingerprint feature information list, etc.
