Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and security risks due to repeated login requirements across multiple devices, especially in environments with imperfect input methods or devices lacking biometric sensors, and multi-user scenarios complicate login procedures.
Innovation Solution
A wearable electronic device equipped with a communication circuit and positioning sensor facilitates automatic login by measuring its location relative to an external device, transmitting user information for seamless login when within a predefined range, and supporting multi-user login scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic login using cache is configured for user convenience, then ease of operation is improved, but security reliability deteriorates
Solution Approach 1:
The patent introduces a wearable device as an intermediary carrier for biometric information (fingerprint, iris, or voice data). This mediator enables secure automatic login by transmitting authenticated biometric data from the wearable device to the target electronic device, thus maintaining security while improving login convenience. The wearable device acts as a trusted intermediary that stores and transmits authentication credentials without requiring the user to manually input passwords.
2Ease of operation
If biometric login method is used, then ease of operation is improved, but adaptability deteriorates due to limited device compatibility
Solution Approach 1:
The patent implements multi-functionality by supporting multiple biometric authentication methods (fingerprint, iris, and voice recognition) within the same system. The wearable device can store and transmit different types of biometric information, and the system adapts to various authentication methods based on device capabilities. This universal approach ensures that the solution works across different device types and scenarios, improving adaptability while maintaining ease of operation.
3Reliability
If manual input procedure is used for login, then security is improved, but ease of operation deteriorates in imperfect touch input environments
Solution Approach 1:
The patent replaces the mechanical manual input process (typing passwords using remote controls or touch interfaces) with an automated biometric authentication system. The wearable device captures biometric data (fingerprint, iris, or voice) and transmits it automatically to the target device, eliminating the need for manual input. This substitution maintains security through biometric verification while dramatically improving ease of operation, especially in environments where manual input is difficult or error-prone.
