Blockchain Dental Record Security via Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical data management systems are insufficiently secure and inconvenient for patients, healthcare providers, and insurers, failing to efficiently leverage digital data generated during medical treatment plans across various platforms.
Innovation Solution
Implementing multi-dimensional blockchain structures to securely store and manage digital representations of medical anatomy, using a two-dimensional blockchain structure that separates textual content on the main blockchain from multimedia content stored externally, ensuring immutability and accessibility while addressing security and privacy concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized data management systems are used, then ease of operation is maintained, but security and reliability of medical data are insufficient
Solution Approach 1:
The patent segments the data management system into multiple distributed nodes across a blockchain network, where each node maintains a copy of the medical records. This segmentation distributes security responsibilities and eliminates single-point failures, thereby improving reliability without requiring a single complex centralized system.
Solution Approach 2:
The patent implements a nested structure where cryptographic hash values are embedded within blockchain blocks, and medical record data is nested within encrypted containers stored on the blockchain. This nested architecture provides multiple layers of security validation, enhancing reliability while maintaining manageable system complexity through modular design.
2Ease of operation
If digital representations of medical anatomy are stored centrally, then accessibility is improved, but security and privacy concerns worsen
Solution Approach 1:
The patent introduces cryptographic hash values and encrypted data containers as intermediaries between the medical records and the blockchain storage system. These intermediaries enable accessible retrieval of medical records while protecting the actual data content, thus maintaining ease of operation while mitigating security and privacy risks.
Solution Approach 2:
The patent creates cryptographic copies (hash values) of medical records that are stored on the blockchain instead of the original sensitive data. These copies enable verification and accessibility of record integrity without exposing the actual medical information, thereby maintaining accessibility while reducing security and privacy vulnerabilities.
3Reliability
If all digital medical data is stored on the blockchain, then security is improved, but device complexity and storage requirements increase significantly
Solution Approach 1:
The patent extracts the actual medical record data from the blockchain storage system and stores it in external encrypted containers or secure medical record systems. Only cryptographic hash values and essential metadata remain on the blockchain, thereby maintaining security through blockchain's immutable structure while reducing the complexity and storage burden of the blockchain itself.

AI summary
A method of cryptographically secured digital dental treatment planning comprises: receiving, at an intraoral scanning system, an intraoral scan of a patient's dentition, wherein the intraoral scan comprises a three-dimensional (3D) surface representing the patient's dentition at a first arrangement; encrypting, at the intraoral scanning system, the intraoral scan to create a cryptographically secured dental record of the patient's dentition; decrypting, at a treatment planning system, the cryptographically secured dental record; determining a target arrangement for the patient's dentition; determining a digital treatment plan for the patient's dentition, wherein the digital treatment plan comprises a series of intermediate arrangements for a series of aligners to move the patient's dentition from the first arrangement toward the target arrangement; adding the digital treatment plan to the cryptographically secured dental record of the patient's dentition; and sending the cryptographically secured dental record of the patient's dentition to one or more data stores.
