Cross-Space App Access Control for Locked Private Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Android 15, users face difficulty in finding and accessing desired content or apps across separate spaces (personal and private) without authentication, as apps and content are not easily transferable or visible between these spaces, complicating the management and operation of applications and content.
Innovation Solution
A control method is implemented that assists users in selecting desired content or apps by displaying guides and enabling space switching, allowing apps to operate across personal and private spaces by unlocking appropriate locks and displaying relevant icons and guides on the device interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content and apps are separated into multiple spaces with lock mechanisms, then security and privacy are improved, but ease of operation deteriorates as users cannot easily access content across spaces
Solution Approach 1:
The patent introduces a space switching mechanism that acts as an intermediary between different secured spaces. When a user wants to access content in another space, the system provides a space switching interface that allows seamless transition between spaces without requiring complete re-authentication, thus maintaining security while improving accessibility across spaces
Solution Approach 2:
The system performs preliminary authentication when entering a secured space, and then maintains the authenticated state across space transitions. This preliminary action eliminates the need for repeated authentication when moving between spaces, improving ease of operation while preserving security through the initial authentication barrier
2Reliability
If apps are restricted to specific spaces, then security is improved, but adaptability deteriorates as apps cannot operate across multiple spaces
Solution Approach 1:
The patent enables apps to function universally across multiple spaces by implementing a space switching mechanism. An app launched in one space can access content and functionality in other spaces through the space switching interface, making the app multi-functional across different secured environments while maintaining the security boundaries of each space
3Reliability
If multiple spaces are implemented without guidance, then security is improved, but ease of operation deteriorates due to lack of user guidance for space switching
Solution Approach 1:
The system provides feedback to users about their current space context and available space switching options. The space switching interface displays information about different spaces and their contents, giving users feedback about where they are and what they can access, which guides users through space transitions while maintaining security protocols

AI summary
A user is enabled to perform an operation more suitably. Each of a plurality of pieces of application software is managed in association with any of a plurality of spaces including a first space where a lock needs to be unlocked and a second space where the lock does not need to be unlocked. In a case where an application program is associated with the first space, control is performed to display a first screen for selecting a content saved in association with the first space. In a case where the application program is associated with the first space, control is performed to display on the first screen a first display item for displaying a guide regarding start of an application program associated with the second space.
