Pattern-Based Mobile Device Unlocking via Touchscreen Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile devices become more powerful and accessible, there is a need for enhanced security measures to restrict access to sensitive information and functions, especially in scenarios where devices may be stolen or accessed by unauthorized individuals.
Innovation Solution
Implementing a pattern-based unlocking system on mobile devices, where users draw a personalized pattern on a touch screen using their finger or stylus, which can include varying speeds and directions, and can be used as a form of authentication, potentially combined with textual passwords or animated badges for additional security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pattern-based unlocking system is implemented, then security against unauthorized access is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or alphanumeric password entry systems with a touch-based pattern drawing interface. Users draw patterns directly on the touchscreen display using their finger or stylus, eliminating the need for physical keyboards or complex password management while enhancing security through biometric-like behavioral patterns.
Solution Approach 2:
The system allows users to create and define their own unique patterns on the touchscreen display. The pattern recognition software automatically captures the drawing trajectory, speed, and pressure characteristics, enabling users to establish personalized authentication methods without requiring system administrator intervention or complex setup procedures.
2Measurement precision
If pattern tracing speed monitoring is implemented, then authentication precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system monitors multiple parameters including tracing speed, pressure, and temporal characteristics of pattern drawing. By analyzing these parameters dynamically, the system can distinguish between authorized users and impostors even when the same visual pattern is drawn, thereby improving authentication precision without requiring users to memorize complex additional sequences.
Solution Approach 2:
The system collects more data than strictly necessary for basic pattern recognition by monitoring tracing speed and pressure variations. This excessive data collection enhances security by capturing behavioral biometrics, while the system processes only the essential features to maintain ease of operation for the end user.
Data Source
AI summary
A computer-implemented method of authenticating a user with a computing device is disclosed. The method involves displaying a grid of selectable visually-distinguishable graphical elements on a device display, receiving from a user of the device a drawn pattern across the selectable graphical elements, comparing the received drawn pattern to information representing a stored authentication pattern for the user, and unlocking access to functions on the device if the received drawn pattern substantially matches the stored authentication pattern.
