Encrypted Application Interface Display for Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying application interfaces on large-screen terminals from small-screen devices do not effectively protect user privacy, as they do not differentiate between secret-related and non-secret-related applications, leading to potential privacy leakage.
Innovation Solution
A method and apparatus that detect whether an application is secret-related, acquire an encrypted display manner, and send application interface data and the encrypted display manner to a first terminal for secure projection, using a network connection, thereby displaying the application interface with an encrypted effect to protect user privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If application interface data is sent to the first terminal for display, then information sharing is improved, but user privacy protection deteriorates
Solution Approach 1:
The patent applies local quality by differentiating display protection levels across different applications. Secret-related applications (messaging, banking, social media) receive encrypted display treatment while non-secret applications (news, video players) display normally. This selective approach enables information sharing for appropriate applications while protecting privacy for sensitive ones, resolving the contradiction between sharing and privacy protection.
Solution Approach 2:
The system performs preliminary action by pre-establishing an encryption database containing encrypted display manners for secret-related applications before the actual display process. When an application is launched, the system checks this database in advance to determine whether encrypted display should be applied, preventing privacy leakage before it can occur while maintaining smooth information sharing for non-sensitive apps.
2Object-affected harmful factors
If encrypted display manner is applied to all applications, then privacy protection is improved, but display clarity and user experience deteriorate
Solution Approach 1:
The patent implements local quality by applying encrypted display manners selectively only to secret-related applications identified in the encryption database, while leaving non-secret applications to display in normal clear mode. This ensures privacy protection where needed without degrading the display clarity and user experience for regular applications, thus resolving the contradiction between protection and usability.
3Object-affected harmful factors
If application classification is implemented, then privacy protection accuracy is improved, but system complexity deteriorates
Solution Approach 1:
The system reduces complexity by performing preliminary action through pre-establishing an encryption database that contains application identifiers and corresponding encrypted display manners. During runtime, the system simply matches the current application's identifier against this pre-prepared database rather than performing complex real-time analysis, thereby achieving accurate privacy protection with minimal system complexity.
Solution Approach 2:
The patent uses copying by storing pre-defined encrypted display manners for different applications in an encryption database. Instead of creating complex encryption logic for each application type, the system copies and applies appropriate encrypted display patterns from the database based on application identifier matching, simplifying the overall system architecture while maintaining high privacy protection accuracy.
