Touch Interface Path Authentication for Secure Device Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accurately determining the correct electronic device for wireless connections, leading to potential erroneous connections, and existing authentication methods can be cumbersome and require password memorization without independent device authentication.
Innovation Solution
A method involving the storage and comparison of touch interface path information between devices, using angles and relative distances based on reference points to normalize and authenticate each device independently, allowing for secure wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing authentication techniques are used, then connection security is improved, but ease of operation deteriorates due to password memorization requirements
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with a biometric touch-based authentication system. Users authenticate by drawing a path on the touch interface, which is captured and compared between devices. This substitution eliminates the need for password memorization while maintaining security through unique biometric path recognition.
2Measurement precision
If device authentication is performed, then connection accuracy is improved, but device complexity increases due to path information storage and comparison mechanisms
Solution Approach 1:
The patent uses copying by capturing and transmitting path information data between devices for authentication purposes. Each device stores a copy of the user's touch path pattern and exchanges this copied data with the other device to verify authenticity. This approach enables accurate device identification without requiring complex cryptographic protocols or hardware security modules.
Data Source
AI summary
A method for authentication is provided. The method includes storing, by a first electronic device, first path information in a memory. The first path information includes data representing a first path of input on a touch interface associated with the first electronic device. One or more first portions of the first path information are communicated to a second electronic device. One or more second portions of second path information are received from the second electronic device. The one or more second portions are compared to the first path information. The second electronic device is authenticated based on similarity between the one or more second portions and the first path information. The method may allow for separate authentication to be performed by each device.
