Unlock Screen Object Segmentation for Secure Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users and employers face inefficiencies and security concerns when using multiple electronic devices for personal and work purposes, as existing solutions do not effectively manage the separation of security perimeters on a single device, risking unauthorized access to sensitive work-related files.
Innovation Solution
Implementing a processor-implemented method that provides multiple perimeters on an electronic device, including a low-security and a high-security perimeter, allowing selective referencing of objects on an unlock display screen based on their associations, thereby preventing unauthorized access to high-security data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple electronic devices are used for personal and work purposes, then security separation is improved, but device efficiency and productivity deteriorate
Solution Approach 1:
The system segments the electronic device into multiple perimeters (personal perimeter and work perimeter) with distinct security levels. Each perimeter contains specific objects (files, applications, data) and enforces separate access controls, allowing secure coexistence of personal and work data within a single device while maintaining productivity.
2Productivity
If a single electronic device is used for both personal and work purposes, then device efficiency is improved, but security integrity deteriorates
Solution Approach 1:
The device is divided into secure perimeters that logically separate personal and work data. This segmentation maintains security integrity by preventing unauthorized access across perimeter boundaries while allowing efficient single-device operation for both personal and professional tasks.
Solution Approach 2:
Different security levels and access policies are applied to different perimeters and objects within the device. The personal perimeter allows broader access for personal convenience, while the work perimeter enforces stricter security controls, enabling each region to have optimized quality characteristics for its specific purpose.
3Ease of operation
If high-security objects are displayed on unlock screen, then user convenience is improved, but security risk increases
Solution Approach 1:
The unlock screen displays objects with security levels matching the current authentication state. Low-security personal objects are visible on the unlock screen for convenient access, while high-security work objects remain hidden until appropriate authentication is provided, balancing user convenience with security protection.
Solution Approach 2:
The system uses perimeter-based security levels as an intermediary mechanism to control what objects appear on the unlock screen. This intermediary layer filters objects based on their security classification and the user's authentication status, preventing direct exposure of high-security objects while maintaining convenient access to low-security personal objects.

AI summary
Methods and devices for selectively allowing a reference to an object to be included on an unlock display screen are described. In one embodiment, a processor-implemented method is described. The method includes: providing a plurality of perimeters on the electronic device, the perimeters including a low-security perimeter and a high-security perimeter; associating one or more objects with the low-security perimeter and one or more objects with the high-security perimeter; and based on the associations between the one or more objects and the one or more perimeters, selectively allowing one or more of the objects to be referenced on an unlock display screen.
