Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Collaboration platforms face challenges in determining which users can interact safely, particularly for minors, as they are vulnerable to abusive interactions and fraudulent activities, requiring a method to establish trusted relationships between users who communicate outside the platform.

Innovation Solution

A collaboration platform authenticates users by transmitting and verifying authentication codes between users who communicate outside the platform, enabling trusted relationships and providing additional functionalities for verified users, while restricting interactions between unverified users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the collaboration platform implements strict authentication and verification mechanisms to ensure user safety, then user security and trustworthiness are improved, but the complexity of the system increases and user engagement may be reduced due to restrictive interactions

Engineering Contradiction:

Improveuser securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments users into different trust levels (trusted friends vs. regular users) based on authentication results. This segmentation allows the system to apply different interaction rules and restrictions to different user groups, thereby maintaining security without uniformly restricting all user interactions, thus reducing the perceived complexity for average users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary authentication actions (crypto verification, social media account linking) before users can establish trusted relationships. By performing these security checks in advance, the system establishes trust credentials beforehand, allowing streamlined interactions later without repeated verification, thus reducing ongoing system complexity.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the collaboration platform allows more unrestricted interactions between users, then user engagement and platform usability are improved, but the risk of abusive interactions and fraudulent activities increases

Engineering Contradiction:

Improveuser engagementVSAvoidabusive interactions

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies different interaction qualities locally based on trust relationships. Trusted friends enjoy unrestricted, high-engagement interactions (messaging, trading, gaming), while regular users face restricted interactions. This local differentiation allows high user engagement among trusted users without exposing the entire platform to abusive interactions.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary trust verification mechanism (crypto authentication, social media verification) that mediates between users. This intermediary layer validates user identities and establishes trust credentials, enabling safe unrestricted interactions for verified users while blocking potential abusive interactions from unverified users.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If the collaboration platform implements comprehensive user verification systems, then trusted relationships are established more reliably, but storage and computational resources are consumed

Engineering Contradiction:

Improvetrust relationship accuracyVSAvoidstorage resources

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and leverages existing verification data from external sources (social media account credentials, crypto wallet signatures) rather than storing comprehensive user profiles internally. By taking out verification responsibilities to external authentication systems, the collaboration platform reduces its own storage requirements while maintaining high trust relationship accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of the platform verifying users directly and storing verification data, the patent inverts the approach by having users prove their identities through external cryptographic or social media verification systems. The platform trusts the external verification mechanisms, thereby reducing computational and storage overhead while maintaining reliable trust establishment.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An indication of a first selection of one or more authentication code elements from a first authentication code elements is received from a first user device corresponding to a first user account associated with a collaboration platform. An indication of a second selection of one or more authentication code elements from a second authentication code elements is received from a second user device corresponding to a second user account associated with the collaboration platform. A determination is made that the first selection of authentication code elements matches the second selection of authentication code elements. Responsive to determining that the first selection of authentication code elements matches the second selection of authentication code elements, a trusted relationship between the first user account and the second user account is established via the collaboration platform.
