Mobile Terminal Sensitive Data Output Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to ensure the confidentiality of sensitive data during video calls in public settings, where unauthorized individuals may overhear or see the content despite encryption, due to reliance on user awareness and lack of automatic security measures.
Innovation Solution
A communication terminal method that determines whether to output sensitive data based on predefined configurations, including secure output via peripheral devices or withholding data if a non-user is nearby, with options to transmit warnings or scramble video to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption and security key exchange are used, then data confidentiality during communication is improved, but users may still inadvertently expose sensitive data in public places
Solution Approach 1:
The system performs preliminary detection of the communication environment (public vs. private) before the communication session begins. Based on this detection, it proactively configures security measures such as enabling peripheral devices or selecting appropriate output modes, so that when sensitive data is transmitted, the security protections are already in place rather than requiring user awareness and manual configuration during the communication.
Solution Approach 2:
The communication terminal automatically detects whether it is in a public or private communication configuration and self-adjusts its data output behavior without requiring user intervention. The system monitors its own environment, determines the appropriate security level, and executes the corresponding security actions (such as routing data through secure peripherals or blocking output) autonomously, making the security mechanism self-managing rather than user-dependent.
2Reliability
If automatic security detection and control mechanisms are implemented, then protection against unauthorized access to sensitive data is improved, but device complexity increases
Solution Approach 1:
The security mechanism is segmented into distinct functional modules: an environment detection module that identifies public vs. private communication configurations, a determination module that decides the appropriate security level, and an execution module that implements the selected security actions. This modular segmentation allows each component to perform a specific function, making the overall complex security system more manageable and maintainable while providing comprehensive protection.

AI summary
A method for outputting sensitive data to a user includes a communication terminal checking to determine whether at least a portion of the sensitive data is to be outputted by determining whether the communication terminal is in one of a plurality of predefined communication configurations for outputting the sensitive data. If the communication terminal is found to be a first configuration, the communication terminal transmits the sensitive data so that at least one of the video data and the audio data is output to the user via at least one peripheral device connected to the communication terminal. If the communication terminal is in a second configuration, the communication terminal performs at least one security action to help further protect the sensitive data.
