Wearable Payment Device State-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current payment systems lack a seamless and secure in-person transaction experience, as they often require repeated authentication and may be vulnerable to fraud when the wearable device is removed or lost.
Innovation Solution
A wearable device that authenticates users upon initial use and maintains payment functionality without re-authentication as long as it remains in a closed state, using NFC or network connections, while revoking access when it is opened or removed, thus preventing unauthorized transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device requires repeated authentication for each transaction, then security is improved, but user convenience and transaction speed deteriorate
Solution Approach 1:
The system performs authentication in advance when the device is first worn or activated, storing the authenticated state for subsequent transactions. This preliminary authentication action eliminates the need for repeated authentication during multiple transactions, resolving the contradiction between security and convenience by maintaining security through state persistence while enabling frictionless subsequent transactions.
Solution Approach 2:
The wearable device automatically manages authentication state and transaction authorization without requiring user intervention for each transaction. The device self-monitors its authenticated status and automatically enables or disables payment functionality based on whether it is worn, eliminating manual re-authentication and providing seamless user experience while maintaining security.
2Ease of operation
If the wearable device allows continuous payment functionality after initial authentication, then user convenience is improved, but security against fraud when device is removed or lost deteriorates
Solution Approach 1:
The system continuously monitors whether the wearable device is being worn through sensors (accelerometer, gyroscope, proximity sensors) and provides feedback by automatically enabling or disabling payment functionality based on the detected state. This real-time feedback mechanism ensures that payment capabilities are only available when the device is on the user's body, resolving the contradiction between continuous convenience and security by dynamically adjusting functionality based on usage state.
Solution Approach 2:
The payment functionality is made dynamic rather than static - it automatically activates when the device is detected as worn and deactivates when removed. This dynamic state management allows the system to provide uninterrupted payment capability during normal use while automatically preventing fraud when the device is taken off or lost, eliminating the need for manual security interventions.
3Reliability
If the wearable device immediately disables payment when opened or removed, then security is improved, but transaction continuity deteriorates
Solution Approach 1:
The system employs periodic sensing and state checking to monitor whether the device is worn, rather than relying on a single static authentication event. Sensors continuously or periodically check device state, and payment functionality is adjusted based on these periodic assessments. This approach ensures security by detecting when the device is removed while maintaining transaction continuity by quickly restoring functionality once the device is worn again, resolving the contradiction between security and productivity.
Data Source
AI summary
A wearable device receives authentication information from a user. In response to verifying the authentication information, the wearable device provides the user with access to one or more payment capabilities of the wearable device. In response to determining that the wearable device has been switched into an open state, the wearable device removes access to the one or more payment capabilities of the wearable device.
