Title:
METHOD AND DEVICE FOR AUTHENTICATING PASSIVE RFID TAG
Document Type and Number:
WIPO Patent Application WO/2021/164039
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for authenticating a passive RFID tag, comprising: acquiring a tag fingerprint of a first tag as a first tag fingerprint, the first tag being a real tag; acquiring a tag fingerprint of a second tag as a second tag fingerprint, the second tag being a tag to be authenticated; comparing the first tag fingerprint with the second tag fingerprint, and if the first tag fingerprint is consistent with the second tag fingerprint, determining that the second tag is a real tag; and if the first tag fingerprint is inconsistent with the second tag fingerprint, determining that the second tag is a forged tag. The tag fingerprint is power-off maintenance time enabling the passive RFID tag to operate normally during a discharge process of discharging after the completion of charging. The present invention has the following beneficial effects of being high in robustness to the change of environment and high in authentication accuracy and capable of being directly deployed on an existing commercial RFID device without modifying hardware of the tag and a reader.
