NFC Identity Packet Generation with Biometric Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ID document verification methods using RFID chips are vulnerable to tampering and require specialized readers, making them inefficient and prone to fraudulent activities.
Innovation Solution
A system that uses a client device with an NFC reader to capture an image of an ID document, extracts printed data via OCR, and compares it with digital data from an RFID chip, ensuring authenticity through biometric verification, allowing for secure self-sovereign identity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID chip verification is used, then ID document authentication is enabled, but the system becomes vulnerable to tampering and requires specialized readers
Solution Approach 1:
The patent makes NFC readers universal by integrating them into standard mobile devices, eliminating the need for specialized RFID readers. The NFC reader can read data from both contactless smart cards and NFC-enabled ID documents, providing multi-functionality that resolves the contradiction between reliability and device complexity
Solution Approach 2:
The system creates a digital copy of the ID document data in the form of a self-sovereign identity packet that can be stored and transmitted electronically. This copy contains verified information from the original ID document, allowing verification without physical inspection and eliminating the need for specialized reading equipment while maintaining security
2Measurement precision
If biometric verification is implemented, then identity confirmation accuracy is improved, but processing time increases
Solution Approach 1:
The system performs biometric verification in advance during the ID document validation phase. The biometric data is captured and verified before the self-sovereign identity packet is generated and stored. This preliminary action ensures high accuracy while making the actual verification process fast, as the biometric check has already been completed
Solution Approach 2:
The user's mobile device automatically performs biometric verification using onboard sensors (camera for facial recognition, fingerprint sensor). This self-service approach eliminates the need for external verification equipment and reduces processing time while maintaining high accuracy through multiple biometric factors
3Ease of operation
If data is stored on NFC chip, then portability is improved, but data tampering risk increases
Solution Approach 1:
The system implements cryptographic hashing and digital signatures before data is stored on the NFC chip or in the self-sovereign identity packet. This beforehand cushioning ensures data integrity by creating immutable verification mechanisms that prevent tampering. The hash values and digital signatures serve as protective measures that detect any unauthorized modifications
Solution Approach 2:
The system incorporates verification feedback loops where the NFC reader reads data from the ID document, verifies it against the self-sovereign identity packet, and provides confirmation of data integrity. This feedback mechanism ensures that any tampering is detected and rejected, maintaining reliability while preserving portability
Data Source
AI summary
Systems and methods of generating user identity packets using biometrics are disclosed herein. An example method includes generating a user identity packet. The user identity packet is generated by verifying that data stored on a near-field communication (NFC) chip of an identification document has not been tampered with, and confirming an identity of an owner of the identification document using both a current biometric and a baseline biometric stored on the NFC chip. The user identity packet is stored on a mobile device. The user identity packet is provided in place of the identification document when a requester has asked for the identification document.
