Blockchain Ingestion Verification via Digital Codes and Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to ensure accurate tracking and verification of pharmaceutical composition ingestion from manufacture to patient, particularly in chronic illness management and substance abuse monitoring, with low adherence rates and potential for tampering in urine samples.
Innovation Solution
A blockchain-based system that registers each pharmaceutical composition dose, uses digital codes for authentication, and captures video evidence of ingestion through mobile application software, ensuring tamper-proof tracking and verification from production to ingestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional urine testing methods are used for adherence monitoring, then cost and simplicity are maintained, but reliability is compromised due to potential tampering and inability to verify actual ingestion
Solution Approach 1:
The system divides the pharmaceutical composition into individually packaged units, each with unique identifiers (first code on outer packaging, second code on container). This segmentation allows tracking of individual doses through the supply chain and verifies patient ingestion by matching codes, eliminating tampering possibilities while maintaining manageable system complexity through modular identification.
Solution Approach 2:
The patent creates digital copies of the pharmaceutical composition's identity through codes and blockchain records. The first and second codes serve as digital fingerprints that can be verified without altering the physical composition. Blockchain stores immutable digital copies of transaction data, enabling verification of ingestion without physical interference with the urine sample or medication.
2Reliability
If blockchain technology is implemented for tamper-proof tracking, then reliability of ingestion verification is improved, but device complexity and implementation cost increase
Solution Approach 1:
The patent introduces blockchain as an intermediary layer between the pharmaceutical supply chain and verification systems. Blockchain acts as a neutral, immutable ledger that records transactions (manufacturing, dispensing, ingestion) without requiring direct trust between all parties. This intermediary enables tamper-proof tracking while distributing complexity across the network rather than concentrating it in a single system.
Solution Approach 2:
The system performs preliminary actions by pre-assigning unique first and second codes to pharmaceutical containers before they reach the patient. The blockchain records are created and sealed in advance, establishing an immutable timeline of the medication's journey. This preliminary setup ensures that when verification occurs, the data is already prepared and cannot be altered, reducing operational complexity during verification events.
3Measurement precision
If video capture and digital code scanning are required for each dose, then measurement precision of ingestion verification is improved, but ease of operation deteriorates
Solution Approach 1:
The patent merges multiple verification functions into a single integrated process: the patient scans both the first code (outer packaging) and second code (container) using their mobile device, which automatically triggers video capture and blockchain verification. This consolidation achieves precise verification of ingestion while simplifying the patient's interaction to a single seamless action, avoiding multiple separate operations.
Solution Approach 2:
The system enables self-service by allowing patients to independently complete the verification process through their mobile devices. The patient simply points the camera at the codes, and the system automatically captures video, scans codes, verifies against blockchain records, and confirms ingestion. This eliminates the need for manual intervention by healthcare providers while maintaining high measurement precision through automated verification.
