Biometric Enrolment via Powered Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometrically authorisable devices, such as smartcards, face challenges in enrolment due to size constraints, limited power resources, and the need for secure and accurate biometric data processing, especially when relying on harvested power without internal storage.
Innovation Solution
A method and system for biometric enrolment that includes a biometrically authorisable device mounted on a holder with a power source, where the power is deactivated during delivery and activated by user manipulation, enabling enrolment via a biometric sensor without external systems, allowing for secure and accurate biometric data storage and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the biometrically authorisable device uses harvested power without internal storage, then the device size and power resource constraints are addressed, but the enrolment process becomes unreliable due to insufficient power availability
Solution Approach 1:
The system is divided into two functional parts: a passive biometrically authorisable device for secure operations and an active holder containing the power source and display for enrolment support. This segmentation allows the device to remain small while the holder provides necessary power and user interface functions during enrolment.
Solution Approach 2:
The holder acts as an intermediary that provides power and display functions during the enrolment process. It mediates between the external environment and the passive device, enabling reliable enrolment without requiring the device itself to have internal power storage.
2Ease of operation
If the power source is always active in the holder, then power is always available for enrolment, but security is compromised during delivery and storage
Solution Approach 1:
The holder is pre-configured with a power source and switching arrangement, but the power supply is kept inactive during delivery and storage. The system is prepared in advance for enrolment while maintaining security by deactivating power until the user actually needs to perform enrolment.
Solution Approach 2:
The power supply state dynamically changes from inactive during delivery to active during enrolment. The switching arrangement enables the system to adapt its power state based on the operational phase, providing security when needed and availability when required.
3Ease of operation
If external systems are used for biometric enrolment, then enrolment can be performed, but security is reduced due to network transmission requirements
Solution Approach 1:
The enrolment capability is extracted from external networked systems and integrated directly into the passive device and holder combination. This allows enrolment to be performed locally without network transmission, eliminating the security vulnerability while maintaining enrolment functionality.
Solution Approach 2:
The system performs enrolment autonomously using the integrated biometric sensor and local processing. The holder provides power and display, while the passive device stores biometric data securely, enabling self-contained enrolment without external system dependency.
4Measurement precision
If the same biometric sensor is used for both enrolment and authentication, then identification accuracy is improved, but the device complexity increases
Solution Approach 1:
The biometric sensor in the passive device serves multiple functions: both enrolment and authentication. This universal use of the same sensor maintains high identification accuracy while avoiding the added complexity of separate sensors for different functions.
Data Source
AI summary
A method is described for biometric enrolment of a biometrically authorisable device having a biometric sensor for identification of an authorised user and a processor capable of permitting access to one or more secure feature(s) based on authentication of the user's identity. The enrolment method includes mounting the biometrically authorisable device to a holder in order to form an enrolment system arranged to be delivered to the end user by mail. The holder has a power source such that during delivery the supply of power is deactivated and the holder includes a switching arrangement configured to activate the supply of power in response to manipulation of the holder. The enrolment system is delivered to the user and the supply of power is activated in response to manipulation of the holder by the user.
