Object-Aware Touch Unlocking via Camera and Pattern Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch screen unlocking methods for portable devices lack enhanced security measures, making them vulnerable to unauthorized access.
Innovation Solution
A method and apparatus that utilize a camera to capture an image of an object and combine it with touch input recognition to determine if the user's touch input matches the object's boundary or texture, with additional security layers including stored images and touch inputs for verification, location-based unlocking, and password recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional button pressing or code entry methods are used for unlocking, then the operation is simple and fast, but the security level is low and vulnerable to unauthorized access
Solution Approach 1:
The patent combines multiple authentication factors (object image recognition via camera, touch input pattern recognition, and location information) into a unified unlocking system. The processor integrates these different verification methods to determine whether to unlock the device, creating a multi-layered security approach that maintains user convenience while significantly enhancing security.
Solution Approach 2:
The patent introduces an object as an intermediary element in the authentication process. The user places a specific object on the touch screen, and the system captures an image of this object to verify its presence and characteristics. This intermediary object serves as a physical token that enhances security without requiring complex user interactions or memorization of codes.
2Reliability
If multiple verification steps are added to enhance security, then the security level increases, but the unlocking time and user convenience decrease
Solution Approach 1:
The system performs preliminary actions by continuously monitoring and analyzing the object image and touch input patterns before the actual unlocking decision is made. The camera captures the object image in advance, and the processor analyzes the touch patterns as they occur, enabling rapid authentication decisions without requiring multiple sequential verification steps that would delay the unlocking process.

AI summary
An end device may include a camera configured to capture an image of an object, a touch screen configured to receive a touch input and a processor configured to determine to unlock the end device based, at least in part, on the image of the object and the touch input.
