Multi-tier Identity RFID Chip Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RFID chips lack selective multi-tier functionality, which can compromise security in sensitive environments by revealing identities unrestrictedly, and they have limited power reception and data transmission capabilities.
Innovation Solution
The RFID chip employs a processor, radio transceiver, and memory to differentiate between generic and unique identities based on the frequency band it is hailed on, providing selective multi-tier information and enhanced security through authentication processes, while also receiving power and transmitting data in higher power frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional RFID chips transmit identity unrestrictedly, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The identity information is segmented into multiple tiers: a first tier containing generic identity information and a second tier containing unique identity information. The RFID chip selectively transmits different tiers based on authentication results, allowing unrestricted generic identity transmission for ease of operation while protecting unique identity information for security.
Solution Approach 2:
Different parts of the identity information have different security characteristics. The generic identity information in the first tier is accessible without authentication for ease of operation, while the unique identity information in the second tier requires authentication for security. This local quality differentiation resolves the contradiction between ease of operation and security.
2Productivity
If RFID chip uses higher power frequency bands for data transmission, then productivity is improved, but use of energy deteriorates
Solution Approach 1:
The RFID chip performs partial action by transmitting only the necessary first tier identity information in lower power frequency bands for routine operations, and reserves second tier unique identity information transmission in higher power frequency bands for authenticated scenarios requiring higher productivity. This partial action approach balances energy consumption with data transmission rate requirements.
Solution Approach 2:
The system changes operating parameters (frequency band and transmission power) based on authentication status and data tier. Lower power frequency bands are used for first tier generic identity transmission to conserve energy, while higher power frequency bands are activated for second tier unique identity transmission when higher data transmission rates are needed and authentication has succeeded, managing the trade-off between productivity and energy use.

AI summary
A method of transmitting a first tier of information by a radio frequency identity (RFID) chip when hailed in a first frequency band and transmitting a second tier of information by the RFID chip when hailed in a second frequency band. The method comprises receiving a first hailing radio signal in a first frequency band by an application executing on a processor of an RFID chip, in response to receiving the first radio signal, transmitting a first tier of information stored in the RFID chip in the first frequency band by the application, receiving a second hailing radio signal in a second frequency band by the application, and, in response to receiving the second radio signal, transmitting a second tier of information stored in the RFID chip in the second frequency band by the application.
