Remote Biometric Authentication for Electronic Device Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices often require users to remember and enter passwords or passcodes for limited access features, which can be cumbersome and may lead to frustration, especially when multiple users share devices with differing preferences, and can result in a time-consuming re-authorization process if access is lost or forgotten.
Innovation Solution
An electronic device with an access controller that uses biometric data from remote sensors, such as fingerprint or retina scanners, to authenticate users and enable or disable operational settings, eliminating the need for traditional passwords by comparing detected biometric characteristics against stored templates and determining similarity exceeding a set threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional passwords or passcodes are used for access control, then security is provided, but user convenience deteriorates due to the need to remember and enter codes
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a biometric authentication system using fingerprint sensors. The fingerprint sensor captures and compares biometric data to verify user identity, eliminating the need for users to remember or manually enter passwords, thus improving ease of operation while maintaining security
Solution Approach 2:
The patent creates a digital copy of the user's biometric特征 (fingerprint) and stores it as a template for comparison. This biometric template serves as a unique identifier that replaces traditional passwords, enabling automatic recognition and authentication without requiring users to recall or input access codes
2Adaptability or versatility
If multiple users share an electronic device, then device utilization is improved, but access control complexity increases due to different user preferences and authorization levels
Solution Approach 1:
The system automatically identifies and authenticates users through biometric scanning without requiring manual intervention for user selection or password entry. The access controller automatically compares the captured fingerprint against stored templates and grants appropriate access based on the verified user's authorization level, eliminating complex manual access control procedures
Solution Approach 2:
The biometric authentication system serves multiple functions: it identifies the user, verifies their identity, determines their authorization level, and automatically applies the appropriate access profile. This single biometric system replaces multiple password management functions, simplifying access control while supporting multiple users with different preferences
3Ease of operation
If biometric authentication is implemented, then ease of operation is improved by eliminating passwords, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The patent integrates the fingerprint sensor and biometric processing capabilities directly into the remote control device, combining multiple functions (biometric capture, template comparison, authentication decision) into a single integrated unit. This merging reduces the need for separate authentication devices and simplifies the overall system architecture while maintaining ease of operation
Data Source
AI summary
An electronic device having at least one operational setting, such as a power setting, with at least a first state and a second state. The electronic device may also include an access controller that can receive state data and authorization data from an external source such as a remote control. The access controller may enable a state of the operational setting upon receipt of proper authorization data received from or related to the output from at least one biometric sensor associated with the remote control.
