Self-Auditing Blockchain Imprint Consensus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain networks face challenges in detecting malicious activities, such as hacks, within peer nodes without compromising trust and requiring access to sensitive information, which can lead to prolonged undetected security breaches.
Innovation Solution
A self-auditing method that generates imprints from process information of peer nodes and compares them to a consensus imprint to detect errors, allowing for real-time identification and localization of malicious activity while maintaining network trust, using a decentralized database and smart contracts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security monitoring methods are used to detect malicious activities in peer nodes, then security breaches can be detected, but access to sensitive information is required which compromises trust and network confidentiality
Solution Approach 1:
The patent extracts only the essential process information (code, data, configuration) from peer nodes to generate imprints, rather than accessing or analyzing the actual sensitive data. This allows security monitoring without compromising confidentiality, as the imprints are cryptographic representations that do not reveal the underlying sensitive information.
Solution Approach 2:
The patent introduces imprints as an intermediary mechanism between security monitoring and peer node data. These imprints serve as mediators that enable detection of malicious activities without requiring direct access to sensitive information, thus maintaining trust while achieving security monitoring.
2Reliability
If centralized security monitoring is implemented to detect hacks, then security breaches can be identified, but a single point of failure is created and trust is compromised
Solution Approach 1:
The patent segments the security monitoring function into individual peer nodes, where each node independently generates and verifies imprints. This distributed approach eliminates the single point of failure inherent in centralized monitoring while maintaining effective security detection across the network.
Solution Approach 2:
The patent makes each peer node universally capable of performing security monitoring functions through imprint generation and verification. Instead of dedicating a separate centralized monitoring system, all peer nodes participate in security monitoring, distributing the function across the network.
3Measurement precision
If detailed process information is collected from peer nodes for security analysis, then malicious activities can be detected, but the complexity of the monitoring system increases
Solution Approach 1:
The patent creates simplified cryptographic copies (imprints) of the essential process information instead of collecting and analyzing the actual detailed data. These imprint copies retain the necessary information for detection while dramatically reducing the complexity of storage, transmission, and analysis requirements.
Data Source
AI summary
A processor may collect process information associated with a peer node of a self-auditing blockchain. The processor may generate an imprint from the process information. The processor may compare the imprint from the peer node to an imprint consensus to detect an error. The error may indicate that the peer node has been compromised.
