Multi-touch Authentication via Touch Pattern Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for information handling devices are either insecure or cumbersome, as traditional text-based/number-based passwords impose cognitive burdens and require physical interaction, while biometric solutions are costly and add weight to devices.
Innovation Solution
A multi-touch input authentication method that detects and associates user inputs on a touch-sensitive surface, such as taps, clicks, and gestures, to form a comparison representation for user authentication, eliminating the need for complex codes and additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional text-based or number-based passwords are used for authentication, then users can protect access to their devices, but the authentication process becomes cumbersome and imposes cognitive burdens on users
Solution Approach 1:
The patent replaces traditional mechanical/password-based authentication with touch-sensitive surface interaction. Users provide authentication through touch patterns, gestures, or sequences on a touch screen, eliminating the need for memorized passwords and reducing cognitive burden while maintaining security through biometric-like touch characteristics
Solution Approach 2:
The authentication system leverages the user's own touch characteristics and natural interaction patterns with the device as the authentication mechanism. The system learns and recognizes the user's unique touch behavior patterns, making the authentication process intuitive and automatic without requiring external credentials
2Reliability
If biometric solutions are implemented for authentication, then authentication security is improved, but device cost and weight increase
Solution Approach 1:
The patent makes the existing touch-sensitive surface serve dual purposes: both as a user interface for normal device operation and as an authentication mechanism. By leveraging the universal touch screen already present in the device, the system provides biometric-like authentication without requiring separate dedicated biometric hardware such as fingerprint sensors or facial recognition cameras
Solution Approach 2:
Instead of using physical biometric traits captured by specialized sensors, the system creates a digital representation or copy of the user's touch interaction pattern. This virtual model of user behavior serves as the authentication credential, eliminating the need for physical biometric collection hardware while maintaining security through unique interaction patterns

AI summary
An embodiment provides a method, including: detecting, at a touch sensitive surface of an information handling device, user input including at least one multi-touch input; said detecting comprising detecting two or more substantially simultaneous user inputs to the touch sensitive surface; associating, using a processor, a number with the at least one multi-touch input; determining, using the processor, if the user input matches expected user input; and responsive to determining a match, authenticating a user. Other embodiments are described and claimed.
