Blockchain Asset Expiration Management via Smart Contracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain systems lack efficient mechanisms for managing assets with expiration dates, particularly in scenarios requiring secure, tamper-proof, and distributed access control, such as in the automotive and healthcare industries.
Innovation Solution
Implementing a method that identifies an expiration date for assets, creates a blockchain transaction including the asset and expiration date, stores this transaction on a blockchain, and grants access to authorized entities with a certificate only if the expiration date has not yet passed, using smart contracts and a distributed ledger system to ensure secure and tamper-proof asset management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain is used to store asset information with expiration dates, then security and tamper-proof properties are improved, but access control complexity increases
Solution Approach 1:
The patent applies preliminary action by embedding expiration date metadata directly into the blockchain transaction during asset creation. This pre-configured time-based access control rule allows the system to automatically enforce expiration logic without requiring complex runtime verification mechanisms, thus improving security while managing access control complexity.
Solution Approach 2:
The blockchain system performs self-service by inherently tracking and enforcing expiration dates through its immutable ledger. The expiration logic is embedded in the transaction structure itself, allowing the system to automatically determine access validity without external intervention, reducing access control complexity while maintaining high security standards.
2Object-affected harmful factors
If expiration dates are tracked on blockchain, then unauthorized access is reduced, but system complexity increases
Solution Approach 1:
The patent merges the expiration date tracking functionality directly into the existing blockchain transaction structure. By combining asset metadata, expiration dates, and access control logic into a single unified transaction format, the system reduces unauthorized access while avoiding the need for separate complex tracking systems.
Solution Approach 2:
The system uses parameter changes by encoding expiration dates as standardized metadata fields within blockchain transactions. This parameter-based approach allows the system to track and enforce time-based access control using existing blockchain mechanisms, reducing system complexity compared to implementing entirely new tracking infrastructure.
3Reliability
If time-based access control is implemented, then asset security is improved, but operation complexity increases
Solution Approach 1:
The blockchain system provides self-service by automatically verifying expiration dates and access rights during transaction processing. The system inherently tracks time-based access control rules embedded in transactions, improving asset security while minimizing operation complexity through automated verification without requiring manual intervention.
Solution Approach 2:
The system implements feedback mechanisms by providing clear verification of access rights based on expiration dates. When entities attempt to access assets, the system automatically checks the embedded expiration metadata and provides immediate feedback on access validity, improving security while keeping operations simple through automated decision-making.
Data Source
AI summary
An example operation may include one or more of identifying an expiration date associated with an asset, creating a blockchain transaction identifying the asset and the expiration date, storing the blockchain transaction on a blockchain, identifying a requesting entity with a certificate permitting access to the asset, and providing the requesting entity with access to the asset provided the expiration date is still pending.
