Selective Screen Unlocking via Motion Track Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen lock mechanisms on electronic devices do not allow users to selectively control which files are displayed when unlocking the screen, potentially exposing personal information to others.
Innovation Solution
The method involves a touch screen with unlocking and non-unlocking blocks, where a processor detects a motion track to release the screen-locking mode, loading all files if the first unlocking sequence is followed, or only authorized files if the second sequence is used, allowing users to choose the level of file exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional screen lock mechanism is used, then the screen can be protected from unauthorized access, but all files will be displayed when unlocked, potentially exposing personal information to others
Solution Approach 1:
The patent segments the file system into multiple groups (first group of files and second group of files) with different access permissions. The screen lock mechanism is divided into multiple unlocking sequences, where the first unlocking sequence grants access to all files while the second unlocking sequence grants access only to the first group of files. This segmentation allows selective file access based on the unlocking sequence used, resolving the contradiction between screen protection and information exposure.
Solution Approach 2:
The patent applies local quality by assigning different access permissions to different groups of files. The first group of files is configured with restricted access (only accessible via the second unlocking sequence), while the second group of files is accessible via either unlocking sequence. This localized permission structure allows certain files to maintain higher security while others remain more accessible, resolving the contradiction between overall screen protection and selective information exposure.
2Object-affected harmful factors
If multiple unlocking sequences are implemented, then selective file access control is achieved, but the operation complexity increases
Solution Approach 1:
The patent implements self-service by allowing users to automatically configure the file groups and unlocking sequences through a settings interface. The system provides default configurations and automated file categorization based on user selections, reducing the manual effort required to set up the dual unlocking sequence system. This automation mitigates the operational complexity while maintaining the security benefits of selective file access control.

AI summary
Disclosed are an electronic device and a method for unlocking screen. The electronic device includes a touch screen, a storage and a processor. The touch screen displays unlocking blocks and non-unlocking blocks in the screen-locking mode of the electronic device. A plurality of files are stored in the storage. In the screen-locking mode, the processor detects a motion track generated when an object is touching the touch screen. If the object has touched the unlocking blocks and the motion track is satisfied with a first unlocking sequence, the processor makes the screen-locking mode released and loads all files. If the object has touched the unlocking blocks and the motion track is satisfied with a second unlocking sequence, the processor makes the screen-locking mode released and loads some of the files. Thus, according to different motion tracks, the electronic device determines to load all or some of the files.
