Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data partitioning with dynamic keys is implemented, then security is improved, but device complexity increases

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the financial network data into multiple partitions, with each partition having its own dedicated encryption key. This segmentation approach isolates security risks to specific partitions while maintaining overall system security, and allows independent management of each partition's access control without affecting other partitions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic key generation and rotation mechanisms where encryption keys are automatically updated based on predefined policies, time intervals, or security events. This dynamic approach ensures that even if one key is compromised, the system can rapidly generate new keys to maintain security without manual intervention.

Inventive Principle:
Principle #15Dynamics

2Productivity

If gamification systems and entity matching are implemented, then productivity is improved, but device complexity increases

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements automated entity matching systems that use AI and machine learning to automatically identify and connect compatible financial entities without manual intervention. The system self-learns from interaction patterns and automatically optimizes matching algorithms, reducing the need for complex manual configuration while improving productivity through automated entity connections.

Inventive Principle:
Principle #25Self-service

3Reliability

If secure chat systems and AI-driven search systems are implemented, then reliability is improved, but loss of time increases

Engineering Contradiction:
ImprovereliabilityVSAvoidloss of time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements pre-computed search indexes and cached authentication results that are prepared in advance for frequently accessed data and common authentication scenarios. This preliminary action allows the system to rapidly retrieve and verify information without performing complete security checks each time, reducing access time while maintaining security reliability.

Inventive Principle:
Principle #10Preliminary action

AI summary

A system includes one or more hardware processors to perform operations for receiving, from a first entity of a financial entity network, a first data request to obtain a private data of a second entity of the financial entity network, and for authenticating the first data request. The operations also include retrieving, from a data repository, an encrypted private data when the first data request is authenticated, and creating, via a dynamic key exchange system, a first single use key. The operations further include providing the first single use key to the first entity, and receiving, from the first entity, a second data request to obtain the private data. The operations also include authenticating the second data request, and providing a second encrypted private data to the first entity when the second data request is authenticated, wherein the second encrypted data is decrypted using the first single use key.
