Wear Device Authentication Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart wear systems face challenges in efficiently recognizing and authenticating users across different devices while minimizing power consumption, as they need to continuously sense and transmit data to function effectively.
Innovation Solution
A wear system and method that detects authentication information in a low-power state, transmits it to a server, and upon authentication, switches to a higher power state to gather user data, which is then transmitted back to the server to generate a user profile and provide relevant services, allowing seamless service provision regardless of the smart wear device used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart wear continuously powers components to sense user presence, then user recognition and service provision are maintained, but power consumption increases significantly
Solution Approach 1:
The system performs preliminary authentication by detecting authentication information (such as biometric data or device identifiers) when the wear device is first put on, before entering continuous monitoring mode. This preliminary action establishes user identity early, allowing the system to transition to lower-power states while maintaining service capability.
Solution Approach 2:
Instead of continuous sensing, the system uses periodic detection cycles where the wear device switches between active sensing states and low-power states. The device periodically checks for user presence and authentication status, maintaining reliability while significantly reducing average power consumption compared to continuous operation.
2Measurement precision
If the smart wear requires authentication information to be registered beforehand, then user identification is accurate, but the system cannot recognize users wearing different smart wear devices
Solution Approach 1:
The system implements a universal authentication mechanism where multiple types of authentication information (biometric data, device identifiers, cloud-synced profiles) can be used across different wear devices. The server stores user profiles that are not tied to a specific device, allowing any authorized wear device to recognize and authenticate the user, thereby achieving both accuracy and cross-device versatility.
Solution Approach 2:
The server acts as an intermediary that stores and manages user authentication information and profiles. When a wear device detects authentication information, it communicates with the server to verify identity and retrieve user data. This intermediary approach decouples the authentication process from specific devices, enabling accurate user identification across multiple wear devices without requiring pre-registration on each individual device.

AI summary
The present disclosure provides a wear system for providing a service. The wear system may comprise a wear device configured to detect authentication information regarding a user wearing the wear device in a first state, to transmit the authentication information to a server, and if authentication of the user is complete through the server, to detect user data of the wear device in a second state and to transmit the user data to the server and the server, upon detecting identification information regarding the user using the authentication information received from the wear device, to complete the authentication of the user, to generate a user profile based on the user data received from the wear device, to store the user profile corresponding to the identification information, and to provide service information related to the user to the wear device.
