Touch Pattern Authentication via Area Shape and Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack diverse and secure unlocking methods, relying primarily on password or pattern inputs, which may not adequately protect user data from unauthorized access.
Innovation Solution
An electronic device with a touch screen and processor that detects touch area, shape, and number of touches to create a reference pattern for unlocking, allowing for variable and secure input patterns based on these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standardized unlocking methods (passwords or patterns) are provided, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent changes the parameters of touch input by detecting and analyzing multiple characteristics including touch area size, touch shape, number of touches, and touch position. These parameter variations create a more complex authentication pattern that maintains ease of use while significantly improving security, as the system recognizes legitimate user patterns based on multiple touch parameters rather than simple password or pattern input
2Reliability
If touch area, shape, and number of touches are detected to create variable patterns, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent makes the touch screen serve multiple functions: it acts as both the display interface and the authentication sensor. The existing touch screen hardware is utilized to detect various touch parameters (area, shape, position, number of touches) without adding separate authentication hardware, thereby improving security while minimizing the increase in device complexity
3Reliability
If multiple touch parameters are analyzed to create reference patterns, then security is improved, but ease of operation is worsened
Solution Approach 1:
The system performs self-learning by automatically analyzing the user's natural touch patterns during the setup phase and creating a reference pattern without requiring the user to manually configure complex parameters. During unlocking, the system automatically compares incoming touch data against the stored reference pattern, making the process simple for the user while maintaining high security through multiple parameter analysis

AI summary
An apparatus and a method for controlling security in an electronic device are provided. The operating method of an electronic device includes detecting at least one touch input of a sequence of touch inputs, detecting at least one of a contact size, a contact shape, or the number of simultaneous contacts in case of a multi-touch input, which correspond to each of the at least one touch input, and creating a reference pattern for the unlocking, based on at least one of the contact size, contact shape or the number of simultaneous contacts in case of a multi-touch input, which correspond to each of the at least one touch input of a sequence of touch inputs.
