Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing access control systems struggle with dynamically generating rules for access to online resources due to the unpredictable combinations of non-fungible token (NFT) attributes, making it impractical to pre-encode comprehensive access control rules.

Innovation Solution

Automate the detection of NFT attribute combinations and their association with online resources, generating access control rules based on verified ownership of NFTs with specific attributes, using blockchain data to validate user devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If access control rules are manually encoded in advance by administrators, then access control can be implemented for predictable conditions, but the system cannot handle unpredictable combinations of NFT attributes

Engineering Contradiction:

Improveability to handle unpredictable NFT attribute combinationsVSAvoidcomplexity of manual rule encoding

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically generates access control rules by detecting NFT attribute combinations and their associations with online resources without requiring manual administrator intervention. The rule generation engine autonomously creates, updates, and manages access rules based on real-time NFT ownership data and resource associations.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Access control rules are dynamically generated and updated based on changing NFT attribute combinations and ownership patterns. The system continuously monitors NFT attributes and automatically adjusts access rules to adapt to new combinations, making the access control mechanism flexible and responsive to unpredictable variations.

Inventive Principle:

Principle #15Dynamics

2Reliability

If comprehensive access control rules are pre-encoded to cover all possible NFT attribute combinations, then complete access control coverage is achieved, but the time required to implement and update rules becomes impractical

Engineering Contradiction:

Improvecompleteness of access control coverageVSAvoidtime to implement and update access rules

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system establishes the framework and infrastructure for automatic rule generation in advance, including the rule generation engine, NFT attribute detection mechanisms, and resource association databases. This preliminary setup enables rapid response to new NFT combinations without requiring time-consuming manual rule creation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors NFT ownership data, attribute combinations, and access patterns, using this feedback to automatically generate and refine access control rules. The feedback loop ensures comprehensive coverage by detecting new NFT combinations and creating appropriate rules in real-time.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If manual administrator creation of access control rules is used, then rules can be carefully crafted for known conditions, but the time sensitivity for implementing access control becomes unworkable

Engineering Contradiction:

Improvesimplicity of rule creation processVSAvoidspeed of access control implementation

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The manual mechanical process of administrator rule creation is replaced with an automated computational system that detects NFT attributes, determines associations with resources, and generates access rules algorithmically. This substitution eliminates the time-consuming manual encoding process while maintaining rule quality through systematic detection and generation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The rule generation engine acts as an intermediary between NFT ownership data and access control enforcement. It automatically translates NFT attribute combinations into access control rules, bridging the gap between raw blockchain data and actionable access decisions without requiring manual intervention.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Methods and systems for access control in an online environment, such as an e-commerce platform. The system receives a designation of a non-fungible token (NFT) collection in connection with a merchant account, each NFT having a respective combination of attributes. An association is detected between a product record and a combination of two or more of the attributes and the system automatically generates an access rule with regard to the product record that is conditional on ownership of an NFT in the collection that has the combination of the two or more attributes. When a request for access is received, the access rule is applied to provide a user device with access to the one or more product records based on verification of the ownership by the user device of an NFT that meets the condition.
