Finger Biometric Sensor for Web Link Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current finger biometric sensors in electronic devices are not optimized for providing a user-friendly and convenient method for accessing and interacting with web links, such as social networking sites or online shopping, which often require manual login and payment entry.
Innovation Solution
An electronic device equipped with a finger biometric sensor, display, and processor that allows users to enroll fingers for specific functions, associate web links with fingers, and perform actions like opening web links or making purchases by authenticating the user's finger, thereby eliminating the need for manual login and payment entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual login and payment entry is required for web links, then security is maintained, but user convenience and operation speed deteriorate
Solution Approach 1:
The system performs preliminary actions by pre-enrolling multiple fingers and pre-associating them with various web links and payment accounts during setup. This preliminary configuration eliminates the need for manual login procedures during actual use, as the system already has the authentication data and account information ready to be automatically retrieved and applied when a finger is scanned.
Solution Approach 2:
The system implements self-service by automatically performing login and payment operations once finger authentication is provided. The biometric sensor scans the user's finger, the processor automatically retrieves the associated web link and payment account information from memory, and executes the corresponding functions without requiring manual intervention for login credentials or payment details.
2Ease of operation
If finger biometric sensor is added to enable automatic authentication, then user convenience improves, but device complexity increases
Solution Approach 1:
The finger biometric sensor and associated processing system are designed with multi-functionality to justify the added complexity. The same biometric authentication mechanism serves multiple purposes: accessing different web links, making payments, and identifying users. By associating multiple functions and payment accounts with different fingers, the system maximizes the utility of the added components.
Solution Approach 2:
The processor acts as an intermediary between the simple biometric sensor and the complex authentication requirements. The processor receives raw biometric data from the sensor, compares it with enrolled fingerprint data in memory, identifies the matching finger, retrieves associated web links and payment accounts, and executes the appropriate functions. This intermediary processing layer simplifies the overall system architecture by centralizing the complex logic.
3Adaptability or versatility
If multiple fingers are enrolled with different functions, then system versatility improves, but enrollment and management complexity increases
Solution Approach 1:
The system segments the authentication and function association process into distinct phases: enrollment phase where users associate fingers with web links and payment accounts, and execution phase where only the fingerprint scanning and automatic function activation occur. This segmentation simplifies management by separating the setup complexity from the operational simplicity.
Solution Approach 2:
Different fingers are assigned different local qualities or characteristics in terms of their associated functions. For example, the index finger might be associated with news websites while the middle finger is associated with shopping sites. This localized association allows users to quickly identify which finger to use for which function, making the system easier to manage and use despite the complexity of multiple associations.

AI summary
An electronic device may include a finger biometric sensor, a display, and a processor coupled with the finger biometric sensor and the display. The processor is capable of displaying a plurality of finger representations on the display corresponding to different fingers of a hand, enrolling respective user's fingers for the plurality of finger representations using the finger biometric sensor, displaying a menu of available functions on the display, associating at least some of the available functions with respective enrolled user's fingers, and performing a given function based upon a match of a newly sensed user's finger with a respective enrolled user's finger using the finger biometric sensor.
