Gesture Unlocking via Word-Induced Object Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face security vulnerabilities due to the use of simple objects for unlocking the lock mode, which can compromise user privacy.
Innovation Solution
An electronic apparatus and method that displays a specific word on the screen, allowing users to set an object related to the word as the unlocking information, and uses similarity matching with predefined objects to ensure a more secure unlocking process, preventing the use of simple objects like checkered shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple object is used for unlocking lock mode, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent introduces a word as an intermediary element between the user and the unlocking object. Instead of directly setting a simple geometric shape, the user first selects a word, and then draws an object associated with that word. This intermediary word layer adds semantic depth and prevents direct use of simple shapes, thereby resolving the contradiction between ease of operation and security.
Solution Approach 2:
The patent requires preliminary selection of a word before allowing the user to draw the unlocking object. This preliminary action of word selection adds an additional step that prevents direct use of simple geometric shapes, while still allowing users to easily recall and draw objects associated with their chosen words.
2Reliability
If word induction is added to object setting, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent employs self-service by utilizing the user's own cognitive associations between words and objects. The system automatically induces relevant objects based on the selected word without requiring complex manual configuration. The user simply needs to draw the object they associate with the word, and the system handles the complexity of object induction and validation automatically.

AI summary
An electronic apparatus is disclosed. The electronic apparatus includes a display, and a processor configured to, based on a user command for setting unlocking information being input, display a screen including a word on the display, and store information on an object drawn on the screen by a user's gesture as the unlocking information, wherein the word is configured to induce an object related to the word to be drawn on the screen.
