Solution Overview

Problem

Existing systems fail to adequately protect personally identifiable information and personal medical data from security threats and do not provide verifiable and trusted sources of medical data.

Innovation Solution

Patient information is stored on a distributed ledger and/or blockchain, with patient keys verified to access outcome measurement devices (OMDs) and responses formatted for storage, optionally associated with smart contracts for incentives and conditions, ensuring secure and verifiable data management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If patient information is stored in traditional systems, then access and management is simplified, but security protection against threats is inadequate

Engineering Contradiction:

Improvesecurity protectionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces blockchain technology as an intermediary layer between traditional healthcare systems and patient data storage. The blockchain acts as a decentralized mediator that verifies and secures patient information without requiring a central authority, thereby enhancing security while maintaining system accessibility through distributed consensus mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments patient data into multiple components stored across different blockchain nodes rather than集中存储 in a single centralized system. This segmentation distributes the security burden across multiple independent entities, making the overall system more resilient to security breaches while maintaining data integrity through cryptographic hashing and distributed verification.

Inventive Principle:

Principle #1Segmentation

2Reliability

If patient information is stored in traditional systems, then storage and retrieval is straightforward, but trust verification of data sources is not provided

Engineering Contradiction:

Improvetrust verificationVSAvoiddata management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a feedback mechanism where blockchain nodes continuously verify and validate patient data through consensus protocols. Each data entry is subjected to cryptographic verification and distributed validation, creating a feedback loop that ensures data authenticity and trustworthiness. This automated verification process provides trust verification without requiring manual intervention or complex administrative oversight.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent applies preliminary cryptographic hashing and digital signature verification to patient data before it is stored on the blockchain. This preliminary action ensures that data integrity is established at the point of entry, and subsequent verification becomes a straightforward process of checking cryptographic proofs rather than re-validating the entire data set, thereby reducing ongoing management complexity.

Inventive Principle:

Principle #10Preliminary action

AI summary

Upon receipt and verification of a patient's key, a medical questionnaire may be provided to a patient via an electronic device (e.g., computer, mobile phone, etc.). A set of responses to the medical questionnaire may be received from the patient and packaged for storage on a blockchain. The packaged set of responses may then be broadcast to the blockchain.
