Solution Overview
Problem
Biometric scanning devices integrated into touch-enabled devices lack efficient methods for secure and accurate biometric data capture, particularly for security and identification purposes, as existing technologies do not effectively utilize the touch interface for biometric data acquisition.
Innovation Solution
A biometric sensor system is integrated into touch-enabled devices, featuring a luminescent layer that emits photons upon contact with a biometric object, which are then captured by an image sensor to produce electrical signals indicative of the biometric data, allowing for secure and accurate biometric data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biometric scanning device is integrated into a touch-enabled device, then security and identification capabilities are improved, but the device complexity increases
Solution Approach 1:
The patent combines the biometric scanning function with the existing touch-screen interface by integrating a luminescent layer and image capture component beneath the touch-screen surface. This merging approach allows the device to serve dual purposes: maintaining touch interaction capabilities while adding biometric identification, thereby improving security without significantly increasing overall device complexity.
Solution Approach 2:
The touch-screen surface is designed to serve multiple functions: it acts as both a standard touch input interface and a biometric scanning surface. The luminescent layer and image capture component enable the same physical surface to capture both touch interactions and biometric data (such as fingerprints), making the device more versatile and secure without requiring separate dedicated components.
2Measurement precision
If a luminescent layer is added to the touch screen, then biometric image quality is improved, but the device structure becomes more complex
Solution Approach 1:
The luminescent layer and image capture component are nested within the existing touch-screen structure. The luminescent layer is positioned between the touch-screen surface and the image capture component, which itself is integrated into the touch-screen assembly. This nested arrangement allows multiple functional layers to coexist in a compact configuration, improving biometric image quality while minimizing structural complexity increases.
3Measurement precision
If photons are emitted upon touch contact, then biometric data capture accuracy is improved, but energy consumption increases
Solution Approach 1:
The luminescent layer emits photons periodically or on-demand upon detecting touch contact, rather than continuously. This periodic activation is triggered only when a user interacts with the touch surface, allowing the system to capture biometric data accurately when needed while minimizing energy consumption during idle periods. The image capture component is similarly activated only during touch events.
