Blockchain Notary Ledger and Micro-Identifier Chains for Medical Data Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems face limitations such as inability to scale, security vulnerabilities, inefficiency, costly consensus mechanisms, and non-compliance with international data privacy laws like GDPR and CCPA, particularly regarding the immutability of data which prevents user data removal as per regulatory rights.
Innovation Solution
A transaction platform utilizing a notary distributed ledger or blockchain combined with micro-identifier chains (MIDCs) that enables secure data storage and compliance with privacy and regulatory laws through single transaction blocks, allowing for data modification and deletion without compromising chain integrity, using a partitioned RAFT replication protocol to enhance transaction throughput and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored on traditional blockchain systems, then data immutability and security are improved, but compliance with data privacy laws (GDPR, CCPA) deteriorates due to inability to remove user data
Solution Approach 1:
The system segments the blockchain into multiple layers: a public immutable layer for cryptographic hashes and a private mutable layer for actual data storage. This segmentation allows the public layer to maintain security and immutability while the private layer enables data modification and deletion for compliance, resolving the contradiction between data security and regulatory compliance.
Solution Approach 2:
The patent introduces notary blockchains as intermediary structures that hold cryptographic proofs and hashes without storing actual personal data. These notary chains act as mediators between the immutable public blockchain and the mutable private data storage, enabling verification of data integrity while allowing data to be modified or deleted to comply with privacy laws.
2Reliability
If traditional blockchain consensus mechanisms are used, then security is improved, but transaction throughput and efficiency deteriorate
Solution Approach 1:
The system segments the consensus process by implementing separate notary blockchains for different data types (medical records, test results, etc.). Each notary chain can be independently validated, allowing parallel processing of multiple transactions simultaneously, thereby increasing throughput while maintaining security through distributed validation.
Solution Approach 2:
The patent implements preliminary validation and hashing of data before it is committed to the blockchain. Data is pre-processed, hashed, and validated off-chain, then only the cryptographic proofs are submitted to the blockchain for consensus. This preliminary action reduces the computational burden on the blockchain consensus mechanism, improving transaction throughput while maintaining security.
3Speed
If single transaction blocks are used, then transaction validation speed is improved, but blockchain scalability deteriorates
Solution Approach 1:
The system segments the blockchain structure into single-transaction blocks for critical verification data and batched data storage for less time-sensitive information. This segmentation allows fast validation of essential cryptographic proofs while storing larger datasets efficiently, achieving both rapid validation and scalability.
Solution Approach 2:
The patent moves data storage to another dimension by implementing off-chain storage for actual data while keeping only cryptographic hashes and proofs on-chain. This dimensional separation allows the blockchain to maintain its fast validation capabilities for critical data while scaling to handle large volumes of medical records and test results stored externally with verifiable proofs on the chain.
