Identity Document Chip Authentication With Pre-Stored MRZ Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity verification methods involving physical handling of identity documents, such as passports, are time-consuming and prone to errors, leading to lengthy queues and authentication failures.
Innovation Solution
A method that minimizes document handling by using a secure communication channel with an identity document's electronic chip, authenticated via a public key pair, without retrieving biometric data or reading the automatic reading zone, allowing contactless verification using a contactless communication means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical handling of identity document is required to read automatic reading zone, then authentication can be performed, but authentication time increases and queues become lengthy
Solution Approach 1:
The patent stores the optical reading datum (MRZ) in advance in a database during document issuance or registration. During authentication, the system retrieves this pre-stored MRZ data and compares it with biometric data, eliminating the need to physically read the MRZ zone from the document during the authentication process. This preliminary storage action resolves the contradiction by maintaining authentication reliability while dramatically reducing authentication time.
2Extent of automation
If automatic reading zone is read to access biometric data, then chip authentication can be performed, but document handling complexity increases
Solution Approach 1:
The patent extracts the MRZ reading step from the authentication process by storing it in advance in a database. The authentication system only needs to perform biometric comparison against the pre-stored MRZ data, without requiring physical document handling or optical reading of the MRZ zone during authentication. This extraction simplifies the operation while maintaining full automation.
3Reliability
If biometric data is read from electronic chip, then secure authentication is achieved, but data security risks increase during data transmission
Solution Approach 1:
The patent extracts the biometric data from the chip during an initial enrollment phase and stores it in a secure database. During authentication, only the MRZ data (which was pre-stored) and biometric templates are compared, without requiring continuous reading or transmission of sensitive biometric data from the chip. This reduces data transmission security risks while maintaining authentication security through secure storage and comparison protocols.

AI summary
A method for checking an individual having an identity document on a medium comprising an electronic chip in which a reference biometric datum of the individual is stored and capable of displaying an automatic reading zone representing an optical reading datum of the identity document, the method includes carrying out by a checking device of acquiring a candidate biometric datum on a biometric trait of the individual, retrieving from the candidate biometric datum in a memory, an optical reading datum associated with the reference biometric datum corresponding to the biometric trait of the individual, and opening a secure communication channel with the electronic chip of the medium of the individual's identity document using said retrieved optical reading datum.
