Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Centralized computer information systems lack the ability to granularly define, digitally communicate, and electronically verify consent for private information, preventing subjects from controlling access and delegation, and existing decentralized ledger technologies do not address these issues due to a lack of interoperability for sensitive information storage and access control.

Innovation Solution

A decentralized database system with client computers that embed access-control objects containing verifiable digital representations of consent, enabling conditional access control, authorization, and traceable transactions for private information across a network, using encrypted data vaults and electronic decentralized ledgers to manage and verify access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If centralized information systems are used to store private information, then information storage and management is simplified, but subjects lose control over access and delegation of their private information

Engineering Contradiction:

Improveinformation storage and managementVSAvoidsubject control over access and delegation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system segments control authority by separating the centralized information storage from decentralized access control. Each subject's private information is associated with unique digital identifiers and cryptographic keys that enable the subject to independently control access permissions and delegate authority to third parties without relying on the centralized system operator for authorization decisions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces cryptographic keys, digital identifiers, and verifiable credential structures as intermediaries between subjects and third parties. These digital artifacts mediate access control transactions by encoding consent, authorization conditions, and delegation relationships in a verifiable manner that both parties can trust without direct communication or centralized coordination.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If conventional electronic decentralized ledger technologies are used, then distributed storage is achieved, but interoperability for sensitive information storage and access control is lacking

Engineering Contradiction:

Improvedistributed storage capabilityVSAvoidinteroperability mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates universal access-control objects and verifiable credential structures that can represent multiple types of consent, authorization, and delegation relationships in a unified format. These standardized digital artifacts enable different decentralized ledger systems to interoperate by providing common data structures and verification mechanisms that work across diverse implementations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the parameters of decentralized ledger technology by incorporating cryptographic verification, verifiable credentials, and access-control objects with specific data structures. These parameter changes transform basic distributed storage into an interoperable system capable of handling sensitive information with provable consent and authorization tracking.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If access control is decentralized to subjects, then subject autonomy is improved, but verification and tracing of consent becomes more difficult

Engineering Contradiction:

Improvesubject autonomyVSAvoidverification and tracing of consent

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements feedback mechanisms through verifiable credentials and access-control objects that automatically track and report consent, authorization, and delegation transactions. Each access event is recorded with cryptographic proof linking back to the subject's original consent, providing continuous verification capability that scales with decentralized autonomy without increasing verification difficulty.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary action by embedding verifiable consent and authorization information into digital artifacts before access transactions occur. Access-control objects are pre-configured with cryptographic proofs of subject consent, authorization conditions, and delegation relationships, enabling automatic verification at the point of access without requiring complex real-time tracing or validation processes.

Inventive Principle:

Principle #10Preliminary action

AI summary

Access by decentralized client computers to private information pertaining to a subject stored in a decentralized database is selectively controlled to facilitate an access-control transaction. The private information is embedded with one or more access-control objects containing an independently-verifiable digital representation of consent by the subject and associated computer instructions to control access to the private information based on consent of the subject. The one or more access-control objects are used to determine whether to selectively authorize access to the private information and then embed with the private information a digital representation of the access-control transaction traceable to the consent of the subject.
