Biometric Template Pre-Check for Secure Document Personalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing biometric document realization processes are slow and prone to delivering defective documents due to time-consuming initialization steps and the risk of template rejection, which is unacceptable for mass production.
Innovation Solution
A method that processes the biometric template with a first part of the biometric algorithm before initialization to ensure compatibility, eliminating the risk of template rejection and ensuring the template is verified and authenticated, allowing for efficient and quick document delivery by signing and encrypting the verified template.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the template is initialized during the first use of the biometric document, then the realization process is accelerated, but there is a risk that the template will be rejected during initialization
Solution Approach 1:
The patent applies preliminary action by performing template verification before personalization. The method includes a verification step that processes the template with a first part of the biometric algorithm to check compatibility before the template is stored on the biometric document. This preliminary verification ensures that only compatible templates are personalized, eliminating the risk of rejection during first-use initialization and enabling the quick delivery method to proceed safely.
2Productivity
If the template is initialized during production, then the document can be delivered immediately, but the initialization step is time-consuming and reduces productivity
Solution Approach 1:
The patent applies segmentation by dividing the biometric algorithm into two parts: a first part used during production for template verification, and a second part reserved for authentication during first use. This segmentation allows the time-consuming initialization step to be eliminated from the production process, as template verification is performed beforehand. The document can be delivered immediately after personalization without waiting for initialization, thereby improving productivity while maintaining reliability.
3Reliability
If a defective template is delivered to the user, then the document must be recalled or reissued, but this increases production costs and time loss
Solution Approach 1:
The patent applies feedback by implementing a verification step that provides immediate feedback on template compatibility before personalization. The method processes the template with the first part of the biometric algorithm and determines whether the template is compatible with the algorithm. Only compatible templates proceed to personalization, while incompatible templates are rejected and trigger a feedback loop to recapture biometric data. This feedback mechanism prevents defective templates from being delivered, eliminating rework time and associated costs.

AI summary
The present disclosure relates to a method (100) for the realization of a biometric document, said method comprising the following steps: - acquiring biometric data from a human user (U), said biometric data being intended to be used by a biometric algorithm (b Al) of said biometric document; - generating a template (Tmp) of the initial biometric data; - determining if the template (Tmp) is compatible with said biometric algorithm (bAl) by processing the template (Tmp) with a first part of said biometric algorithm (bAl), said first part of the biometric algorithm either generating a verified template (vTmp) if the template is compatible, or rejecting the template if the template is incompatible.
