Blockchain Inventory Ledgers With Access-Level Data Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inventory tracking systems lack the ability to provide secure, customizable, and efficient management of sensitive data while maintaining privacy and ensuring compliance with privacy laws, particularly in contexts like parking facilities, hotels, gaming, and autonomous vehicles.
Innovation Solution
A blockchain-based system that maintains a distributed ledger of block entries with access levels, allowing for customized views of data portions based on user authorization, using encryption and hashing techniques to secure sensitive information and comply with privacy laws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a distributed blockchain ledger is used to store inventory data, then data security and privacy protection are improved, but data accessibility and customization for different users deteriorate
Solution Approach 1:
The patent segments the blockchain data into multiple layers: public data layer, private data layer, and confidential data layer. Each layer has different access permissions and encryption levels. This segmentation allows different users to access only the data portions they are authorized to view, thereby maintaining data security while improving accessibility for authorized users.
Solution Approach 2:
The patent implements local quality by assigning different access permissions and encryption characteristics to different portions of the blockchain data. Each data field can have its own access control policies, allowing fine-grained control over what specific users or user roles can view or modify, thus balancing security requirements with operational accessibility.
2Reliability
If access control mechanisms are implemented on blockchain data, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring access control policies and encryption schemes during blockchain data generation. Access permissions, encryption keys, and decryption algorithms are established in advance for different data fields and user roles, eliminating the need for complex real-time access control decisions and reducing system operational complexity.
Solution Approach 2:
The patent introduces an intermediary layer (confidential computing module) that handles the complex encryption and decryption operations. This intermediary module acts as a mediator between the blockchain data and users, managing the complexity of access control mechanisms while presenting a simplified interface to end users and maintaining privacy protection.
3Productivity
If customized data views are provided to different users, then operational efficiency is improved, but data management complexity increases
Solution Approach 1:
The patent implements dynamics by providing dynamic, customized data views to different users based on their roles, permissions, and needs. The system automatically adjusts which data fields are visible and accessible to each user without requiring manual configuration for each user, thereby improving operational efficiency while managing complexity through automated rule-based customization.
Data Source
AI summary
A blockchain of block entries that can be requested by users from user devices is maintained in a distributed network of nodes. Block entries include a plurality of data portions that are each associated with an access level. A request from an auditor to view one or more data portions of a block entry can includes an access code associated with at least one access level can be evaluated to identify one or more data portions associated with the access level. A customized view of the block entry which includes the one or more data portions associated with the access level can be generated. An artificial intelligence engine can review entries within the distributed ledger, identify earnings information associated with the sales of the commercial inventory, determine tax based on earning information, and pay the tax via fiat or cryptocurrency to government authorities based on earnings information.
