Dynamic Security Mode for Financial Apps in Multi-Person Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as smartphones, are vulnerable to security breaches when financial information is accessed in public, as onlookers can view sensitive data, leading to potential theft or robbery.
Innovation Solution
The electronic device determines the number of persons within a predefined environment using sensors and adjusts the operation of financial, messaging, or banking applications accordingly, switching to a security mode that masks numerical financial data and converts visual prompts to audio when multiple persons are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If financial applications display numerical financial data on the user interface, then usability and user experience are improved, but security and privacy are compromised when multiple persons are present
Solution Approach 1:
The system dynamically adjusts the display mode of financial data based on the detected number of persons. When multiple persons are detected, the application automatically switches to security mode, masking numerical financial data and converting visual prompts to audio. When a single person is detected, the application displays full financial information. This dynamic adaptation resolves the contradiction by making the system both easy to use (full display when alone) and secure (masked display when others are present) at different times.
2Loss of information
If the device operates in normal mode displaying all financial information, then information completeness is improved, but vulnerability to theft and robbery increases in public environments
Solution Approach 1:
The system performs preliminary detection of the environment (number of persons present) before displaying financial information. Based on this detection, it proactively takes anti-action by masking financial data and converting visual prompts to audio when multiple persons are detected, preventing potential security breaches before they can occur. This preliminary protective measure resolves the contradiction by ensuring security reliability in public environments while maintaining information completeness when appropriate.
3Object-affected harmful factors
If the device switches to security mode masking financial data, then security and privacy are improved, but user convenience and accessibility deteriorate
Solution Approach 1:
The system dynamically switches between normal mode and security mode based on environmental conditions. In normal mode (single person detected), the system provides full information display for maximum convenience. In security mode (multiple persons detected), it masks financial data for protection. This dynamic behavior ensures that user convenience is maintained when security risks are low, while security protection is activated when risks are high, resolving the contradiction between these two opposing requirements.
4Loss of information
If visual prompts are converted to audio prompts in security mode, then information confidentiality is improved, but energy consumption and device complexity increase
Solution Approach 1:
The system substitutes the visual display mechanism with an audio output mechanism for delivering financial information and prompts. Instead of relying solely on the display screen (visual), the system uses the audio output device (speaker) to convey the same information verbally. This substitution maintains information confidentiality in security mode while utilizing existing hardware components, thereby limiting the increase in device complexity to primarily software-level changes rather than requiring entirely new hardware systems.

AI summary
An electronic device includes a user interface, one or more sensors, a communication device, and one or more processors operable with the user interface, the one or more sensors, and the communication device. The one or more processors determine, with the one or more sensors, whether one or more persons are within a predefined environment of the electronic device. Where only one person is within the predefined environment, the one or more processors operate one or more of a financial application, a messaging application, or a banking application in a normal mode of operation. Where two or more persons are within the predefined environment, the one or more processors operate the one or more of the financial application, the messaging application, or the banking application in a security mode of operation.
