Solution Overview

Problem

Existing electronic prescription management systems face challenges in ensuring reliable and secure access to prescription-related information and processes, particularly in verifying the identity of users through conventional multi-factor authentication methods that can be invasive and time-consuming.

Innovation Solution

Implementing voice-based authentication and audio interactions for single-factor and multi-factor authentication, selecting communication modes based on device configuration and user context, and customizing voice interactions to enhance user access to prescription resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional multi-factor authentication methods are used to verify user identity, then security and reliability of access to prescription information is improved, but user convenience and time required for authentication deteriorate

Engineering Contradiction:

Improveidentity verification accuracyVSAvoidauthentication convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces conventional mechanical authentication methods (keyboards, buttons, visual displays) with voice-based authentication. Users provide voice commands and speak passphrases that are processed by voice recognition software, eliminating the need for physical interaction with device interfaces during authentication. This substitution maintains security while significantly improving ease of operation, especially for users with mobility impairments or those who need hands-free access.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the authentication parameter from visual/tactile input (typing passwords, pressing buttons) to auditory input (voice commands and spoken passphrases). This parameter change allows users to authenticate through speech rather than physical interaction, improving convenience and accessibility while maintaining reliable identity verification through voice pattern recognition and passphrase validation.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If voice-based authentication is implemented to improve user convenience, then authentication time and complexity are reduced, but system complexity and security requirements increase

Engineering Contradiction:

Improveauthentication process complexityVSAvoidauthentication security

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The authentication process is segmented into distinct voice-based stages: initial voice command recognition to identify the user's intent, followed by passphrase verification, and finally access grant. This segmentation simplifies the overall process by breaking down complex multi-factor authentication into manageable voice-driven steps, reducing perceived complexity while maintaining security through multiple verification layers.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The voice authentication system serves multiple functions: it identifies the user, verifies their identity through passphrase recognition, and grants appropriate access levels. This multi-functionality consolidates what would traditionally require separate authentication steps into a unified voice-based process, reducing system complexity while maintaining comprehensive security checks.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple communication modes are provided for authentication, then adaptability to different user contexts and devices is improved, but system complexity increases

Engineering Contradiction:

Improvecommunication mode flexibilityVSAvoidsystem configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically selects and switches between different communication modes (voice, text, visual) based on the user's context, device capabilities, and environmental factors. This dynamic adaptability allows the authentication process to automatically adjust to the situation without requiring complex manual configuration, improving versatility while keeping system complexity manageable through automated mode selection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system automatically determines the most appropriate communication mode based on device configuration and user context without requiring manual setup or complex user decisions. The authentication system self-configures by detecting available modes and selecting the most suitable one, thereby improving adaptability while minimizing the complexity burden on users and system administrators.

Inventive Principle:

Principle #25Self-service
