Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for capturing biometric data require an assistant and cannot be independently sent to users, limiting accessibility and convenience, especially for those in remote areas or with mobility issues.
Innovation Solution
A mobile terminal equipped with a data memory, authentication module, sensor, control unit, and verification unit that allows for secure, autonomous capture and verification of biometric data, ensuring high trustworthiness and eliminating the need for expensive infrastructure or trained personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric data capture is performed using existing mobile terminals with assistant support, then data capture capability is achieved, but accessibility and convenience are limited due to requirement of trained personnel and expensive infrastructure
Solution Approach 1:
The mobile terminal enables users to independently capture and verify their own biometric data through automated authentication and verification processes, eliminating the need for trained personnel or complex infrastructure. The device performs self-verification of biometric authenticity and automatically manages data capture without external assistance.
2Ease of operation
If autonomous biometric capture is implemented without assistant, then accessibility and convenience are improved, but trustworthiness and verification reliability may be compromised
Solution Approach 1:
The mobile terminal incorporates an automated verification unit that provides immediate feedback on the authenticity of captured biometric data. The system continuously monitors and verifies biometric characteristics in real-time, comparing them against stored reference data to ensure trustworthiness while maintaining autonomous operation.
Solution Approach 2:
The system performs preliminary authentication and verification checks before finalizing biometric data capture. The verification unit pre-validates the authenticity of biometric characteristics during the capture process, ensuring reliability is established before the data is finalized and stored.
3Reliability
If expensive infrastructure and trained personnel are used for biometric capture, then verification reliability is ensured, but costs and device complexity increase
Solution Approach 1:
The patent extracts the verification functionality from complex external infrastructure and integrates it directly into the mobile terminal. The verification unit is embedded within the device itself, removing the need for separate verification systems, trained personnel, or expensive external infrastructure while maintaining verification reliability.

AI summary
The invention relates to a mobile terminal (104) for capturing the biometric data (BD) of a user (112). The terminal comprises: - a data storage device (216) with an authorization certificate (BN) and an indication of a permissible period; - an authentication module (304); - a sensor (208, 210) for capturing the user's biometric data; - a watch (232); - a control unit (316) configured to automatically or semi-automatically capture the user's biometric data (BD) using the sensor only after successful mutual authentication of the user and the mobile terminal; - a verification unit (308) for automatically verifying the authenticity of the captured biometric data.The control unit is configured to store the captured biometric data in the data storage (216) in a protected form only if the captured biometric data is genuine according to the verification and if the current time recorded during biometric data capture falls within the permissible time period. The authentication module (304) is configured to authenticate an operator (106) to the mobile terminal using additional authentication data (AD3) assigned to the operator. The control unit is configured to allow the reading of the protected biometric data only in the event of successful operator authentication, in order to transfer the read biometric data to a security document (116).
