Abstract

This invention discloses a USB storage device security identification and behavior control system and method, belonging to the field of peripheral device control technology. It includes: a device registration module for collecting protocol feature information of the USB storage device and encrypting it to generate a unique static fingerprint; a device identification module for collecting the static fingerprint and behavior features of the connected USB storage device and comparing them with a pre-set whitelist to determine the execution permissions of the USB storage device; and an access control module for performing control operations on data interaction between the USB storage device and the file server based on the execution permissions of the USB storage device. This invention, based on a USB storage device identity fingerprint authentication mechanism using static hardware features and dynamic behavior features, eliminates the risk of bypassing through USB flash drive cloning and identifier tampering, achieving accurate and reliable device identity authentication.
