Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized electronic medical record system is implemented to provide complete medical history, then data accessibility and integration are improved, but data security and privacy compliance deteriorate due to multiple access points and centralized storage vulnerabilities
Solution Approach 1:
The patent segments the centralized medical record system into distributed blockchain blocks, where each record is divided into cryptographically linked segments stored across multiple nodes. This segmentation allows multiple providers to access different portions of patient data without compromising the entire system, resolving the contradiction between accessibility and security by enabling selective access while maintaining data integrity through cryptographic hashing and distributed storage.
Solution Approach 2:
The patent introduces cryptographic intermediaries including digital signatures, hash functions, and blockchain consensus mechanisms that mediate between data accessibility and security requirements. These intermediaries enable verified access control where providers can authenticate and access patient records without directly compromising data security, as all access is mediated through cryptographic verification and authorized key pairs.
2Reliability
If blockchain technology is used to ensure data integrity and security, then data reliability is improved, but system complexity and computational requirements worsen
Solution Approach 1:
The patent uses cryptographic copying through hashing, where each medical record block contains a hash of the previous block, creating an immutable chain without requiring duplication of entire records across all nodes. This copying mechanism ensures data integrity through cryptographic verification while reducing system complexity by storing only essential verification data (hashes and signatures) rather than full record copies at every node.
Solution Approach 2:
The patent implements preliminary cryptographic actions during record creation, including digital signing and hashing, so that data integrity is established before distribution. This preliminary action reduces ongoing system complexity by pre-computing verification mechanisms, allowing nodes to validate records without complex real-time verification processes.
3Duration of action of stationary object
If data is stored permanently to ensure lifetime health records, then data longevity is improved, but data portability and ability to update records deteriorate
Solution Approach 1:
The patent implements a dynamic blockchain structure where records can be appended, updated, and ported while maintaining permanent storage of historical data. The immutable blockchain ensures longevity of past records, while the ability to create new blocks and update references enables ongoing portability and modification. Patients can export their record history and import it to new providers through the standardized blockchain interface, resolving the contradiction between permanent storage and adaptability.
4Measurement precision
If independent verification mechanisms are implemented to ensure data authenticity, then measurement precision is improved, but processing time and system overhead worsen
Solution Approach 1:
The patent performs preliminary verification through cryptographic signatures and hashes at the point of data creation and storage. This preliminary action ensures high verification accuracy because authenticity is established upfront through digital signatures, allowing rapid verification later without time-consuming re-validation processes. Nodes can quickly verify records by checking pre-computed cryptographic proofs rather than performing complex verification calculations each time.
Data Source
AI summary
A decentralized data authentication system integrates blockchain technologies, independent verification software, a decentralized certificate authority system implemented in the cloud, and a centralized redundant database system that together form data portability systems and data longevity systems that enable the creation of integrated lifetime health records that can be accessed by the patient, provider, and payer using public/private keys. Data portability is provided through creation of a decentralized certificate authority system that allows users to sign and later verify data that has been offline. The decentralized certificate authority system also enables tracking of data and timestamping of data via a neutral timestamping mechanism, such as the blockchain, that cannot be altered.
