Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices in security systems lack reliable user authentication, often relying on complex fingerprint scanners or allowing unauthorized use, which complicates and enlarges the devices.
Innovation Solution
A system comprising a wearable device and an authentication device that uses a security token mechanism, where the wearable device transmits a signal indicating its worn state to trigger security actions, and the authentication device verifies the user's control through a secure token exchange, enabling secure and simplified user authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint scanners are added to wearable devices for user identification, then authentication reliability is improved, but device complexity and physical size increase
Solution Approach 1:
The patent extracts the authentication function from the wearable device itself and relocates it to a separate authentication device. The wearable device only needs to generate and transmit a security token, while the complex authentication logic and verification processes are performed by the external authentication device, thus maintaining authentication reliability while reducing wearable device complexity
Solution Approach 2:
The patent introduces an authentication device as an intermediary between the wearable device and the security system. This intermediary handles the complex authentication processes, allowing the wearable device to remain simple while still providing reliable authentication through the token-based verification mechanism
2Reliability
If fingerprint scanners are added to wearable devices for user identification, then authentication reliability is improved, but physical size increases
Solution Approach 1:
The authentication functionality is extracted from the wearable device and placed in a separate authentication device. The wearable device only contains the minimal components needed to generate and transmit security tokens, significantly reducing its size while maintaining authentication reliability through the external verification process
3Device complexity
If simple possession-based authentication is used in wearable devices, then device complexity is reduced, but security reliability deteriorates
Solution Approach 1:
The patent replaces physical biometric verification (fingerprint scanning) with an electronic token-based authentication system. The wearable device generates cryptographic security tokens that are verified by the authentication device, providing strong authentication reliability through mathematical verification rather than physical characteristics, while keeping the wearable device simple
Solution Approach 2:
The patent changes the authentication parameter from physical biometric data to cryptographic token verification. This parameter change allows authentication to be performed through simple token transmission and verification processes, maintaining both low device complexity and high authentication reliability through the mathematical security of the token verification mechanism
