Abstract

This utility model discloses a wireless data privacy protection device, including a USB flash drive body. A fingerprint recognition device is disposed on one side of the surface of the USB flash drive body. A physical protection mechanism for physically preventing the USB flash drive from being inserted into a computer interface is disposed at the lower end of the fingerprint recognition device. The physical protection mechanism includes a limiting rod, a screw, a micro stepper motor, and a threaded sleeve. The limiting rod is movably inserted into the lower end of the USB flash drive body, and a screw is fixedly disposed at one end of the limiting rod. This utility model has good performance. When the fingerprint is not unlocked, the physical limiting rod prevents the USB flash drive from being inserted into the computer interface. Essentially, it combines biometric verification with physical structural protection to form a dual protection mechanism. This design aims to solve the potential risks of traditional fingerprint USB flash drives relying solely on software encryption (such as brute-force attacks on computer big data and side-channel attacks). By directly blocking the data transmission path through a physical barrier, the protection effect of this device can be further improved.
