Solution Overview

Problem

Medical and wellness devices are vulnerable to tampering and misuse, leading to potential harm, and there is a need for anti-tampering and security features to ensure the safety and integrity of treatments.

Innovation Solution

Implementing a secure medical device with a secure enclave, anti-tampering functionality, and a blockchain network to ensure treatments are immutably published, authenticated, and authorized, using sensors to detect tampering and encryption to protect data integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If medical devices are made more secure with anti-tampering features, then treatment safety and integrity are improved, but device complexity increases

Engineering Contradiction:

Improvetreatment safetyVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into distinct functional modules: secure enclave for cryptographic operations, anti-tampering sensors for physical monitoring, blockchain client for decentralized verification, and treatment execution system. Each module operates independently but coordinates through standardized interfaces, allowing the security features to be added without redesigning the entire device architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A blockchain network acts as an intermediary between the medical device and the treatment delivery system. The blockchain verifies treatment authorization and integrity externally, allowing the device to maintain simplicity while achieving enhanced security through distributed verification rather than complex internal validation mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If blockchain verification is implemented for treatment authorization, then treatment integrity is improved, but processing time increases

Engineering Contradiction:

Improvetreatment integrityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Treatment protocols and authorization parameters are pre-loaded into the device's secure enclave during manufacturing or initial setup. This preliminary action eliminates the need for real-time blockchain verification of basic treatment parameters, allowing rapid execution while maintaining integrity through selective on-chain verification only for critical authorization steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements partial blockchain verification rather than comprehensive verification for all operations. Critical authorization transactions are verified on-chain, while routine treatment execution relies on pre-validated local parameters. This selective approach provides sufficient integrity assurance without the processing overhead of full verification for every operation.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

System and methods utilizing specialized hardware and transactions with a public blockchain protect a medical or treatment device from misuse or malicious alteration. The blockchain allows treatments to be immutably published as readable specifications or in an encrypted format. The device will not start to function without a valid interaction with the blockchain. Patient identification, treatment authorization by a healthcare provider, and payment for services are also enabled by this system.
