Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Distributed blockchain networks face challenges in maintaining equal authorization rights for all entities, requiring a system to manage varying security levels and permissions for different users or entities to ensure data security and access control.

Innovation Solution

A rights management protocol is implemented within a blockchain distributed network, allowing financial institutions to manage access, generation, editing, and validation rights based on user security levels, enabling tiered dedicated blockchain configurations with varying security and functionality levels, and authorizing actions based on user credentials and access payments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If equal authorization rights are provided for every entity in a distributed blockchain network, then the network maintains simplicity and equal access, but it cannot provide differentiated security levels for different types of information

Engineering Contradiction:

Improvesecurity level differentiationVSAvoidauthorization management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by assigning different security levels and authorization rights to different entities based on their specific needs and the sensitivity of the data they access. Each entity receives customized authorization rights (full read/write, validation, retrieval, viewing) rather than uniform access, allowing critical data to have higher security restrictions while non-critical data remains accessible. This resolves the contradiction by making authorization rights adaptive to local security requirements without requiring complete system redesign.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the blockchain network into multiple security zones with different authorization levels. Entities are divided into different security categories (e.g., high-security entities for critical data, standard entities for general data). This segmentation allows the system to manage complexity by handling each segment with appropriate security measures rather than applying uniform complex security to all entities.

Inventive Principle:

Principle #1Segmentation

2Reliability

If higher security levels are implemented for certain data, then data security is improved, but access control complexity increases

Engineering Contradiction:

Improvedata securityVSAvoidaccess control mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-defining security levels and authorization rights for different entities before they access the blockchain network. Entities are assigned to security categories in advance based on their identity and purpose, with predetermined authorization rights. This eliminates the need for complex real-time security evaluations during data access, as the security checks simply verify whether the entity's pre-assigned rights match the data's security requirements.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The blockchain network itself maintains the security protocols and authorization verification mechanisms, rather than requiring external complex access control systems. The distributed ledger inherently tracks entity identities and their assigned security levels, automatically enforcing access control rules through smart contracts or protocol-level validation. This self-service approach reduces external complexity while maintaining high security.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If tiered security levels are implemented, then appropriate security measures can be applied to different transactions, but the system complexity increases

Engineering Contradiction:

Improvesecurity measure customizationVSAvoidsystem operation simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a universal authorization framework that handles multiple security levels and entity types through a single set of principles and mechanisms. The same blockchain protocol and authorization verification process works for all security levels, from high-security critical data to lower-security general data. This multi-functionality allows the system to be adaptable to different security requirements while maintaining uniform operation procedures, thus preserving ease of operation despite security customization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Embodiments enable a system to determine, authorize, and adjust access, writing, retrieval, and validation rights of users and entities associated with one or more distributed block chain networks. The system is capable of receiving an authorization request from a user to conduct an action associated with the block chain distributed network, determine a security level associated with the user, and either authorize or screen the user from conducting the action based on the determined security level. The system may adjust the security level of the user by requesting and receiving additional authorization credentials from the user. Furthermore, the system may adjust the security level of one or more users based on security or functionality needs of the block chain distributed network.
