Acoustic Authentication Interface for Secure Transaction Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard PIN pads with known alphanumeric configurations pose security risks in transactions, especially in virtual reality environments and for visually impaired individuals, as observers can easily detect authentication data by watching user interactions.
Innovation Solution
An acoustic authentication data entry interface is generated, where a random sequence of characters is presented to the user through sounds, allowing selection without a visible, predictable layout, thereby obscuring the entry from observers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard PIN pad with known alphanumeric configuration is used, then the interface is simple and familiar to users, but security is compromised because observers can easily detect authentication data by watching user interactions
Solution Approach 1:
The patent applies dynamics by making the character configuration dynamic and changeable rather than static. The system randomly generates different character arrangements for each authentication session, so the layout changes over time. This prevents observers from predicting authentication data based on fixed positions, while the system automatically manages the complexity of generating and tracking these dynamic configurations.
Solution Approach 2:
The patent transitions from a two-dimensional visual layout problem to a multi-dimensional solution by adding audio output and temporal variation. Instead of relying solely on spatial arrangement of characters, the system incorporates auditory feedback and time-varying configurations, creating a richer interaction space that prevents visual eavesdropping while maintaining user guidance.
2Reliability
If a random sequence of characters is used instead of standard layout, then security is improved by obscuring authentication data from observers, but device complexity increases due to need for random generation and audio output
Solution Approach 1:
The patent applies universality by making the display device perform multiple functions: it displays visual characters, generates audio output of those characters, and manages random sequence generation. This multi-functionality consolidates what could be separate complex components into a single versatile device, reducing overall system complexity while achieving the security benefits of random character sequences with audio feedback.
Solution Approach 2:
The system applies self-service by automatically generating random character sequences and managing the authentication interface without requiring external configuration. The device autonomously handles the complexity of randomization, audio-synchronized display, and session management, freeing users from dealing with interface complexity while maintaining high security through unpredictable character arrangements.
3Adaptability or versatility
If audio recording of characters is played to user, then visually impaired individuals can accurately input data, but the system requires additional audio processing capabilities
Solution Approach 1:
The patent merges the audio output function with the existing display and randomization system. Instead of adding a separate audio generation subsystem, the system integrates audio playback with the character display logic, where the same random character sequence that drives the visual interface also drives the audio output. This consolidation achieves accessibility for visually impaired users while minimizing additional system complexity.
Data Source
AI summary
Systems and methods are disclosed for generating an acoustic authentication data entry interface. One method comprises generating a random sequence of characters and a visual user interface element comprising a plurality sections, each section of the visual user interface element being associated with a respective character of the generated random sequence of characters. A section of the visual user interface elements is displayed to a user. Concurrently, an audio recording of a character associated with the displayed section is played to the user. Based on determining user selection of the displayed section, the character associated with the displayed section is logged as part of an authentication data. When all of the characters constituting the authentication data are logged, an electronic transaction authorization request is sent to an acquirer processor.
