Content Security via Selective Display and Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing contents on electronic devices, such as encryption or separate storage, limit access for authorized applications, causing inconvenience even for authorized users.
Innovation Solution
An electronic device with a memory, display, and processor that selects and outputs specific contents based on user input, and requires user verification upon ending the content display, allowing only selected contents to be viewed and restricting access to others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contents are encrypted or stored in a separate storage area, then security against unauthorized access is improved, but accessibility for authorized applications deteriorates
Solution Approach 1:
The patent divides the storage system into multiple storage areas (first storage area for secured contents, second storage area for other contents). The processor selectively accesses different storage areas based on application authorization, allowing both security for specific contents and accessibility for authorized applications simultaneously.
Solution Approach 2:
Different security characteristics are applied to different storage areas. The first storage area has restricted access for security, while the second storage area has broader access for convenience. This local differentiation resolves the contradiction by applying security only where needed rather than uniformly across all contents.
2Ease of operation
If all contents are made accessible to applications, then ease of use is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The system performs preliminary classification of contents into secured and non-secured categories during storage. This preliminary action allows authorized applications to freely access non-secured contents while maintaining security restrictions on secured contents, resolving the contradiction between ease of use and security.
Solution Approach 2:
The processor acts as an intermediary that mediates between applications and storage areas. It determines whether an application is authorized to access specific contents and routes access requests accordingly, enabling both broad accessibility and targeted security protection.

AI summary
An electronic device is provided. The electronic device includes a memory configured to store contents, a display configured to output the contents, and a processor operatively connected with the memory and the display. The memory is further configured to store instructions that, when executed, cause the processor to, in response to a first user input, select at least one contents satisfying a specified condition among a plurality of contents stored in the memory, output a first screen composed of the selected at least one contents in the display, and if a second user input to end the output of the first screen is received, output a second screen for verification of a user of the electronic device in the display.
