Blockchain Access Auditing for Protected Data Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data service providers face challenges in monitoring and auditing access to protected data, leading to increased risks of unauthorized access and difficulty in determining compliance with access regulations, especially in decentralized systems like blockchain.
Innovation Solution
Implementing a unified ledger system using smart contracts on a private blockchain to manage access requests and a public blockchain for compliance logging, with a process compliance monitor (PCM) to ensure authorized access and record transactions for auditing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used to store protected data, then data security and immutability are improved, but the risk of unauthorized access increases and monitoring capability deteriorates
Solution Approach 1:
The patent introduces smart contracts as intermediary components that mediate between data storage and access control. These smart contracts automatically enforce access policies and record all access attempts on the blockchain, providing both security and monitoring capabilities without requiring centralized control.
Solution Approach 2:
The system implements continuous feedback mechanisms where access events are automatically recorded and monitored on the blockchain. This creates a transparent audit trail that provides real-time feedback on data access patterns, enabling detection of unauthorized access attempts while maintaining security.
2Stability of the object's composition
If decentralized blockchain systems are implemented, then data integrity is improved, but access monitoring and auditing capability deteriorates
Solution Approach 1:
The patent employs self-service mechanisms where the blockchain system automatically monitors and audits its own access events through smart contracts. The decentralized network nodes collectively verify and record access transactions, eliminating the need for centralized monitoring while maintaining comprehensive audit capabilities.
Solution Approach 2:
Smart contracts serve as intermediaries that automatically track and log all data access events on the blockchain. These contracts enforce access control rules and create immutable audit records, enabling monitoring in decentralized systems without compromising data integrity.
3Object-affected harmful factors
If access control systems are added to blockchain data storage, then unauthorized access prevention is improved, but system complexity increases
Solution Approach 1:
The patent merges access control functionality directly into the blockchain infrastructure through smart contracts. By combining data storage, access control, and auditing into a unified blockchain-based system, the overall system complexity is reduced compared to separate centralized systems, while maintaining strong unauthorized access prevention.

AI summary
Systems and methods for enabling auditing access to protected data stored at a data service using smart contracts on a blockchain are disclosed. According to certain aspects, a compliance management system may maintain and update a public blockchain with transaction indicative of non-compliance events associated with access to the protected data. Auditors or other third parties may access the public blockchain to audit the access to the protected data. Additionally, the compliance management system may implement a private blockchain to manage access restrictions to the protected data and process data requests for the protected data.
