A treatment device incorporating a secure enclave, blockchain communication, and anti-tampering mechanisms, along with user authentication, ensures secure and authorized treatment delivery by interacting with a blockchain network to retrieve and execute treatment lists and recipes, while detecting and preventing unauthorized access or tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional centralized databases or cloud storage solutions are used to store treatment data, then data accessibility and ease of operation are improved, but data integrity and security deteriorate due to potential tampering by administrators or cyberattacks
Solution Approach 1:
The patent introduces a blockchain network as an intermediary between the treatment device and the centralized database. The blockchain acts as a mediator that verifies and validates treatment data before it is stored or accessed, ensuring data integrity while maintaining accessibility. The decentralized nature of the blockchain prevents single-point failures and administrative tampering.
Solution Approach 2:
The patent segments the data storage and verification function across multiple nodes in the blockchain network rather than relying on a single centralized database. This segmentation distributes the trust and verification responsibility across the network, making the system more reliable and resistant to tampering while maintaining data accessibility through the distributed ledger.
2Reliability
If treatment devices are made more secure with blockchain integration and secure enclaves, then data integrity and security are improved, but device complexity increases
Solution Approach 1:
The patent extracts the cryptographic security functions and blockchain communication capabilities into a separate secure enclave module. This extraction isolates the complexity of security mechanisms into a dedicated component, allowing the main treatment device to benefit from enhanced security without the complexity being distributed throughout the entire system. The secure enclave handles all security operations independently.
Solution Approach 2:
The patent implements a universal security framework where the secure enclave and blockchain integration serve multiple functions: data encryption, authentication, authorization, and integrity verification. By making the security layer multi-functional, the patent reduces the need for separate security components for each function, thereby managing complexity while enhancing security.
3Reliability
If treatment parameters are made immutable on blockchain, then data integrity and compliance are improved, but adaptability and versatility deteriorate as treatments cannot be modified
Solution Approach 1:
The patent implements preliminary action by storing the treatment protocol and parameters on the blockchain before execution. The immutable blockchain record establishes the authorized treatment parameters in advance, and the secure enclave verifies that any modifications to treatment execution do not deviate from the pre-stored protocol. This allows flexibility in execution while maintaining integrity of the core treatment parameters.
Solution Approach 2:
The patent introduces dynamics by allowing the treatment execution system to adapt and adjust parameters within the constraints set by the immutable blockchain protocol. The secure enclave enables dynamic verification during treatment execution, allowing real-time adjustments while ensuring all changes remain compliant with the original authorized protocol stored on the blockchain.

AI summary
The invention relates to a treatment device (101), a secure treatment system (100, 200), and a method for securely authorizing and executing treatments using a blockchain network (170). The treatment device (101) comprises at least one processor (140), a secure enclave (150) for cryptographic security, and an application configured to retrieve a treatment list from the blockchain network (170), request authorization for a selected treatment, and retrieve a corresponding treatment recipe for execution. The system (100, 200) comprises at least one treatment device (101), a blockchain network (170), and a control client device (230) configured to execute a blockchain transaction with the blockchain network (170) via a control smart contract (245). Each treatment device (101) is configured to request authorization to execute a selected treatment from the treatment list, wherein the system (100, 200) determines whether authorization is granted before providing the corresponding treatment recipe. The method ensures secure and verifiable treatment execution while preventing unauthorized modifications.
