Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable terminals, such as wristwatch-type devices, are often too large and cumbersome for continuous wear, leading to a demand for more compact alternatives with integrated authentication functions, particularly for ring-type devices that require accurate biometric authentication positioning.
Innovation Solution
An authentication device and system that includes a wearing position determination unit and an authentication unit, utilizing biometric information detected by sensors to authenticate the wearer, with features like vein pattern recognition and position guidance through LED indicators, ensuring accurate alignment and secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wristwatch-type wearable terminal is used for authentication, then authentication function is provided, but the device becomes too large and cumbersome for continuous wear
Solution Approach 1:
The patent divides the authentication system into two parts: a compact ring-type wearable terminal that can be continuously worn, and a separate authentication execution unit (such as a smartphone or authentication server). The ring contains only essential components for biometric data collection (sensor unit) and communication, while the authentication processing is performed remotely, resolving the contradiction between providing authentication function and maintaining wearability.
2Ease of operation
If a ring-type wearable terminal is made compact, then wearability is improved, but accurate biometric authentication positioning becomes difficult
Solution Approach 1:
The patent introduces an intermediary authentication execution unit (smartphone or authentication server) that receives biometric data from the ring-type wearable terminal and performs authentication processing remotely. This intermediary handles the complex authentication logic and positioning verification, allowing the ring itself to remain compact while maintaining accurate authentication capability through the coordinated action of the intermediary system.
3Ease of operation
If finger placement position is not accurately controlled, then authentication can be performed, but authentication accuracy decreases due to misalignment
Solution Approach 1:
The patent incorporates a feedback mechanism where the authentication execution unit receives not only biometric data but also positioning information from the ring-type wearable terminal. The system uses this feedback to verify whether the finger placement position is within the acceptable range for accurate authentication. If misalignment is detected, the system can request re-positioning or adjust authentication parameters, thereby maintaining high authentication accuracy while keeping the operation simple for the user.

Data Source
AI summary
An authentication device includes: a wearing position determination unit that determines a wearing position, the wearing position being a position at which a wearable article comprising a sensor is being worn on a body; and an authentication unit that performs authentication by using biometric information of the body, the biometric information being detected by the sensor at the wearing position.
