Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CAPTCHA or pattern-lock-based authentication is used, then unauthorized access is prevented, but user convenience deteriorates due to cumbersome interaction

Engineering Contradiction:
ImprovesecurityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent transforms static authentication challenges into dynamic live challenges that change in real-time based on context parameters. The challenge content, timing, and presentation are dynamically adjusted to prevent automation while maintaining user-friendly interaction, resolving the contradiction between security reliability and ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters of the authentication challenge simultaneously - timing parameters (real-time generation), content parameters (context-based variations), and interaction parameters (adaptive difficulty). This multi-parameter approach enhances security while adapting to user behavior patterns for improved convenience.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If static credentials are used for authentication, then ease of operation is maintained, but security deteriorates due to vulnerability to automation attacks

Engineering Contradiction:
Improveauthentication simplicityVSAvoidsecurity against automation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces static credentials with dynamic live challenges that are generated and must be completed in real-time. The challenges incorporate temporal elements and context-aware variations that make automation difficult while keeping the interaction simple for human users, thus improving security against automation attacks while maintaining authentication simplicity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where the challenge generation and validation process adapts based on user responses and context parameters. This feedback loop creates authentication challenges that are simple to interact with but increasingly difficult to automate, resolving the contradiction between ease of operation and security against automation.

Inventive Principle:
Principle #23Feedback

3Reliability

If context-aware live challenges are generated, then security is enhanced through interactive authentication, but device complexity increases

Engineering Contradiction:
Improveauthentication securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional authentication system that combines context parameter collection, live challenge generation, real-time validation, and adaptive difficulty adjustment within a single integrated framework. This universal approach enhances security through interactive authentication while managing device complexity through consolidation of functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system employs self-service mechanisms where context parameters are automatically collected from available device sensors and data sources, and challenges are autonomously generated and validated without requiring complex external infrastructure. This reduces device complexity while maintaining enhanced security through interactive authentication.

Inventive Principle:
Principle #25Self-service

4Device complexity

If traditional authentication methods are used, then device complexity is low, but productivity deteriorates due to time-consuming authentication processes

Engineering Contradiction:
Improveauthentication system complexityVSAvoidauthentication speed
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent performs preliminary actions by pre-collecting and caching context parameters before authentication is needed, and pre-generating potential challenge templates. During actual authentication, these pre-prepared elements are quickly assembled and presented, reducing authentication time while maintaining low device complexity through efficient use of preliminary preparations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements rapid challenge generation and validation by skipping unnecessary processing steps and using optimized algorithms for context parameter analysis and challenge verification. This rushing through the authentication process improves productivity while keeping device complexity low through efficient, streamlined operations.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

A method of authenticating a user includes obtaining a user authentication request for access to at least one application executed on an electronic device, identifying an actor and a task for authentication based on one or more context parameters associated with at least one of the electronic device or a user, providing a live challenge generated based on the identification, and identifying whether to access the at least one application based on whether the provided live challenge has been successfully performed.
