Gesture Authentication for Wireless Payment Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
NFC-equipped mobile devices face security challenges in transmitting sensitive payment information due to lack of secure authentication methods, making them vulnerable to unauthorized access and eavesdropping, especially for users with disabilities who find traditional password systems cumbersome.
Innovation Solution
A gesture-based authentication method that allows users to define and store personalized payment gestures on their mobile devices, which are compared to authenticate and authorize wireless transmission of protected payment data to NFC readers, enhancing security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password systems are used for authentication, then security is provided, but ease of operation deteriorates for users with disabilities
Solution Approach 1:
The patent replaces the mechanical/physical interaction required by traditional keypads and password entry with acoustic field-based authentication. Voice commands and audio patterns allow users to authenticate without physical dexterity, substituting acoustic interaction for mechanical input methods that are difficult for users with disabilities.
Solution Approach 2:
The patent changes the authentication parameter from visual/tactile (passwords on screens or keypads) to acoustic (voice patterns and audio recognition). This parameter change enables users with visual or physical impairments to authenticate through voice, improving ease of operation while maintaining security through voice pattern recognition.
2Device complexity
If virtual keypads are used for password entry, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The patent replaces the visual/tactile interaction required by virtual keypads with acoustic field-based voice recognition. This substitution eliminates the need for users to visually locate and physically tap small screen elements, replacing it with natural voice commands that are easier to execute and more accessible.
3Ease of operation
If simple authentication methods are used, then ease of operation is improved, but reliability deteriorates due to unauthorized access
Solution Approach 1:
The patent replaces simple but insecure methods like basic PIN entry with acoustic pattern recognition that analyzes voice characteristics,语调, and speech patterns. This provides more robust security while maintaining ease of operation, as the system automatically verifies acoustic patterns without requiring complex user input.

AI summary
A method of gesture based authentication for wireless payment by a mobile electronic device is disclosed. In one aspect, the method includes determining that an applied gesture above a touch receptive area of a target device is associated with a user-defined payment gesture stored locally within the mobile electronic device. The method may include comparing the applied gesture above the touch receptive input area of a mobile electronic device with a user-defined payment gesture stored locally within the mobile electronic device. If the applied gesture above the touch receptive input area of a mobile electronic device matches the user-defined payment gesture stored locally within the mobile electronic device, the method includes permitting the wireless transfer of protected payment data resident on the mobile electronic device to an external reader using near-field communication technology.
