Multi-device Biometric Enrollment via Preliminary Hand Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional biometric identification systems require users to visit a specific location for enrollment, which is inconvenient and limits user experience, as they need to provide identification data and biometric input data separately.
Innovation Solution
A multi-device biometric identification system that allows users to initiate the enrollment process using a general input device, such as a smartphone or tablet, which acquires enrollment data and images of the hand using visible light, and later completes the process at a biometric input device using infrared imaging, streamlining the process and eliminating the need for separate steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users visit a specific location for enrollment to provide biometric input data, then the system can ensure secure and accurate data collection, but user convenience is reduced and enrollment time increases
Solution Approach 1:
The system performs preliminary enrollment actions through a second computing device (smartphone/tablet) before the user actually uses the biometric input device. The general input device captures images and acquires identification data in advance, creating a pending enrollment that is later confirmed when the user interacts with the biometric input device, thus resolving the contradiction between advance preparation and actual use convenience
Solution Approach 2:
The system introduces a second computing device as an intermediary between the user and the biometric input device. This intermediary device (smartphone or tablet) handles the initial data collection and enrollment process, allowing users to enroll conveniently using devices they already possess, while the biometric input device serves as a confirmation point, thus improving ease of operation without compromising security
2Measurement precision
If users provide identification data and biometric input data in separate steps at a specific location, then the system can verify identity accurately, but the enrollment process becomes complex and time-consuming
Solution Approach 1:
The system merges the identification data collection and biometric image capture processes into a single unified enrollment flow. The second computing device simultaneously handles both identification data input and biometric image acquisition, then combines these with the subsequent biometric input device interaction to complete enrollment in one streamlined process, reducing complexity while maintaining verification accuracy
Solution Approach 2:
The system performs preliminary data collection through the second computing device, acquiring both identification data and biometric images before the user reaches the biometric input device. This preliminary action prepares the enrollment package in advance, so that when the user interacts with the biometric input device, the verification can be completed immediately without requiring separate steps, thus simplifying the overall process
3Reliability
If the system requires enrollment at a specific location before use, then it can ensure secure enrollment, but user experience is limited and enrollment time increases
Solution Approach 1:
The system performs preliminary enrollment actions through the second computing device (smartphone/tablet) that users already possess and carry. Users can initiate enrollment anytime and anywhere using their personal devices, eliminating the need to travel to a specific enrollment location. The biometric input device then serves as a confirmation point, completing the secure enrollment process in a single interaction rather than requiring a dedicated enrollment visit, thus significantly reducing enrollment time while maintaining security
Solution Approach 2:
The second computing device acts as an intermediary that enables users to complete enrollment remotely using devices they already have. This intermediary handles the initial data collection and prepares the enrollment package, allowing users to enroll without visiting a specific location. The biometric input device then verifies and confirms the enrollment, maintaining security requirements while eliminating the time loss associated with traveling to and waiting at an enrollment center

AI summary
User enrollment to a biometric identification system begins on selected general input devices (GID) such as smartphones. The user may enter identification data (e.g. name) and use a red-green-blue (RGB) camera of the GID to acquire a first image (e.g. hand). The first image is processed using both a first model to determine a first representation and a second model to determine a second representation. Upon presentation of a hand at a biometric input device, a second image is acquired using a first modality and a third image is acquired using a second modality. The second image is processed using the first model to determine a third representation. The third image is processed using the second model to determine a fourth representation. Given a match between both the first and third representations, as well as the second and fourth representations, enrollment is completed by storing the third and fourth representations.
