Mobile Wallet Activation from Locked State via Gesture and Fingerprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices face inconvenience in performing shopping services due to the need for multiple operations to execute payment applications, especially when the device is in a locked or disabled state.
Innovation Solution
A mobile device equipped with a sensor to detect user gestures and fingerprint recognition, enabling the display unit to execute a wallet application and perform payments directly from a locked state by matching preset gesture information and fingerprint verification, allowing communication with external apparatuses for seamless transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple operations are required to execute payment applications, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-registering fingerprint information and preset gesture information in advance. When a user needs to make a payment, the system only requires a simple gesture input followed by fingerprint verification, rather than requiring multiple sequential operations. The fingerprint data is captured and stored beforehand, enabling rapid authentication when needed.
2Reliability
If the device remains in locked state for security, then security is improved, but productivity deteriorates
Solution Approach 1:
The system introduces gesture recognition as an intermediary mechanism between the locked state and payment execution. The gesture sensor detects specific gestures (such as swiping patterns or button combinations) that serve as a preliminary authentication step, allowing the system to transition from locked state to payment interface more quickly while maintaining security through the subsequent fingerprint verification.
3Reliability
If complex authentication procedures are used, then reliability is improved, but device complexity deteriorates
Solution Approach 1:
The system implements a universal authentication framework where the same gesture sensor and fingerprint sensor can be used for multiple purposes: gesture recognition for application launching, fingerprint verification for payment authentication, and potential integration with other security features. This multi-functional approach reduces the need for separate dedicated components for each authentication method, thereby reducing overall device complexity while maintaining robust security.

AI summary
A mobile device is provided. The mobile device includes a display unit, a sensor configured to sense user's touch done on a surface of the display unit in a disabled state of the display unit, a storage unit configured to store preset gesture information, a controller configured to enable the display unit when a user's touch operation matched with the gesture information is sensed, execute a wallet application, and display an execution screen, and a communication unit configured to transmit information for a selected payment option to an external apparatus when the payment option is selected on the execution screen and perform a payment. The payment is simply done.
