Solution Overview

Problem

Existing systems face difficulties in transferring access tokens between user accounts, particularly when account types are different, as compatibility is hard to determine without additional contextual information, leading to security and usability issues.

Innovation Solution

A system that retrieves and compares parameters of user accounts to determine compatibility, using machine learning models to validate access token migrations, ensuring seamless transitions and security by allowing or blocking transfers based on predefined rules and learned patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If access tokens are transferred between user accounts, then user experience is improved by maintaining seamless access, but security risks increase due to potential misuse or incompatibility

Engineering Contradiction:
Improveaccess token migrationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary validation by retrieving and comparing account parameters before allowing access token migration. This includes checking account types, ages, expiration dates, and other parameters against predefined rules to ensure compatibility and security before the migration occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides feedback to users about whether their access token can be migrated to a new account by comparing account parameters and applying predefined rules. This feedback mechanism helps users understand the compatibility status before initiating migration.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If access tokens are made portable between accounts, then usability is improved, but compatibility issues arise when account types differ

Engineering Contradiction:
Improveaccount portabilityVSAvoidaccount compatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system changes parameters such as account type, age, expiration date, and other attributes to determine compatibility between source and destination accounts. By evaluating these parameter changes and differences, the system can accurately assess whether an access token is suitable for migration.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system establishes a universal compatibility framework that can handle various account types and scenarios through predefined rules. This allows the same migration mechanism to work across different account configurations while maintaining security and compatibility.

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

3Ease of operation

If access token migration is allowed without validation, then ease of use is improved, but harmful factors increase due to potential misuse

Engineering Contradiction:
Improvetoken transferVSAvoidmisuse prevention
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary validation by retrieving and comparing account parameters before allowing access token migration. This includes checking account types, ages, expiration dates, and other parameters against predefined rules to ensure compatibility and security before the migration occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary validation layer that mediates between the source account and destination account. This intermediary layer compares parameters and applies rules to determine whether migration should be permitted, preventing direct unauthorized transfers.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Methods and systems are described herein for moving access tokens for validating network operations between user accounts to prevent malicious or nonaligned usage. The system may determine that a user is associated with a first user account and a second user account, retrieve parameters associated with the first and second user accounts, determine that an access token is available for migration, update a binding associated with the access token from the first to the second user account, and, in response to receiving a network operation request, may process the request using the second user account.
