Biometric Button Assembly for Fast Secure Function Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices require passwords or passcodes for restricted functions, which can be inconvenient and may not provide secure access control, especially for devices that need to be easily accessible by authorized users.
Innovation Solution
Integration of biometric sensors, such as fingerprint sensors, into buttons to authenticate users and control access to specific functions, allowing only authorized users to perform restricted actions by matching obtained biometric data with pre-authorized data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passwords or passcodes are used for restricted functions, then access control is provided, but convenience and speed of access are reduced
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 fingerprint patterns to verify user identity, eliminating the need for manual password entry while maintaining security. This substitution of authentication mechanism directly resolves the contradiction by providing both security and convenience.
Solution Approach 2:
The biometric authentication system uses the user's own fingerprint as the authentication key, eliminating the need for external authentication devices or memory of passwords. The system automatically captures and verifies the fingerprint, providing seamless authentication that improves both convenience and speed of access while maintaining reliable security control.
2Reliability
If passwords are required for restricted functions, then security is maintained, but operational speed and efficiency are reduced
Solution Approach 1:
The system performs preliminary authentication by continuously monitoring or pre-capturing fingerprint data before restricted functions are needed. When a user attempts to access a restricted function, the authentication is already prepared or can be performed instantly through the fingerprint sensor, eliminating the time delay associated with password entry and verification, thus improving operational speed without compromising security.
Solution Approach 2:
The patent replaces the time-consuming password entry and verification process with instantaneous biometric verification. The fingerprint sensor can capture and verify authentication in a fraction of a second compared to manual password entry, directly improving operational speed and efficiency while maintaining the same level of security through reliable biometric matching.
3Adaptability or versatility
If conventional authentication methods are used, then device functionality is accessible, but user convenience and ease of use are compromised
Solution Approach 1:
The biometric authentication system allows the device to authenticate users automatically using their own fingerprint, eliminating the need for them to remember or enter passwords. This self-service approach makes the device more adaptable to different users while significantly improving ease of operation, as each user can access restricted functions simply by placing their finger on the sensor.
Solution Approach 2:
The fingerprint sensor provides a universal authentication method that works for all users of the device, replacing the need for individual password configurations. This multi-functional authentication system maintains device accessibility for authorized users while greatly improving convenience, as the same sensor serves all authentication needs without requiring users to learn or remember different credentials.
