RFID Tag Pseudo ID Authentication for Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
RFID tag data protection is inadequate as tags can transmit information to unauthorized RFID readers, compromising privacy, especially during transactions.
Innovation Solution
Implementing a pseudo ID authentication system where only authenticated RFID readers receive a key to access the tag's information, ensuring that only authorized devices can read the tag's data by generating and verifying a pseudo ID using a shared key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID tag transmits data to any RFID reader, then ease of operation is improved, but information security deteriorates
Solution Approach 1:
The patent introduces a pseudo-ID as an intermediary between the RFID tag and readers. Instead of transmitting the real RFID identifier directly, the tag transmits a pseudo-ID that serves as a mediator. This allows legitimate readers to access tag information through authentication while preventing unauthorized readers from obtaining sensitive identification data, thus resolving the contradiction between ease of operation and information security.
2Object-affected harmful factors
If RFID tag uses authentication system with pseudo ID and key, then information security is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-storing the pseudo-ID and authentication key in the RFID tag during manufacturing or initial setup. This preliminary configuration enables the tag to perform authenticated communication without requiring complex real-time generation or management of security credentials, thus improving information security while minimizing the increase in device complexity.

AI summary
A radio frequency identification (RFID) tag, an RFID privacy protection system, and an RFID privacy protection method are provided. The RFID privacy protection method includes a pseudo identification (ID) used to authenticate the RFID reader and a key used to generate the pseudo ID are received; if the pseudo ID is received in response to an information request signal for reading information of the RFID tag comprising the pseudo ID, the key is transmitted; and if a pseudo ID generated using the key is equal to the pseudo ID received in response to the information request signal, an RFID of the RFID tag to read the information of the RFID tag is received.
