Call Screen Personal Information Masking via Dynamic Display Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IVR services face a significant security risk due to the plaintext display of personal information on call screens, particularly in public settings, which can lead to information exposure and compromised user experience.
Innovation Solution
A method and device that dynamically switch the display mode of a call screen between direct and indirect display, replacing entered characters with preset characters when personal information is required, ensuring that sensitive information is hidden from view during IVR interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If personal information is displayed in plaintext form on the call screen, then user input visibility is improved, but information security is worsened
Solution Approach 1:
The patent implements dynamic display mode switching between direct display (plaintext) and indirect display (masked with preset characters). The system automatically transitions between these modes based on the interaction state, providing plaintext display during normal operations and masked display when personal information is being entered, thus resolving the contradiction between visibility and security
Solution Approach 2:
The patent changes the display parameter of the input display area by switching between two display modes: direct display mode showing actual characters and indirect display mode showing preset characters (masking). This parameter change allows the same display area to serve both security and visibility requirements at different times
2Reliability
If display mode is switched to indirect display for security, then information security is improved, but user experience is worsened
Solution Approach 1:
The patent implements feedback mechanisms to detect when personal information entry is occurring (through voice prompts, menu directory matching, or character sequence analysis) and automatically switches to indirect display mode. This feedback-based automatic switching reduces the need for manual user intervention while maintaining both security and usability
Solution Approach 2:
The system performs self-service by automatically detecting the need for masked display through voice recognition, menu directory matching, or character sequence analysis, and switches display mode without requiring explicit user commands. This automatic self-adjustment maintains user experience while ensuring security
3Ease of operation
If automatic detection is implemented to switch display mode, then ease of operation is improved, but device complexity is worsened
Solution Approach 1:
The patent employs a multi-functional detection mechanism that can identify personal information entry scenarios through multiple methods (voice prompt tone recognition, menu directory matching, character sequence analysis). This universal detection approach handles various situations through a unified system, improving ease of operation while managing complexity through consolidation
Data Source
AI summary
A method includes obtaining by detection by a device, characters entered by a user after establishing a call to another device, and when determining that a display mode of a call screen is indirect display, replacing the obtained characters with preset characters and displaying the preset characters in an input display area.
