Resource Access Blockchain Segmentation for Anomaly Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blockchain solutions are inefficient for tracking access events and anomaly detection due to their traditional structure, which is not designed for mixed block types and becomes inefficient as the blockchain lengthens.
Innovation Solution
A resource access blockchain is created to track various types of resource access events by generating blocks associated with these events and adding them to the blockchain, allowing for efficient tracking and anomaly detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional blockchain structure is used to track resource access events, then the blockchain can store access records, but the system becomes inefficient for quickly identifying access, tracking transactions, and anomaly detection as the blockchain lengthens
Solution Approach 1:
The patent segments the blockchain into multiple specialized chains: an administration chain for access rights management, a login chain for authentication events, and a user access chain for resource access tracking. This segmentation allows each chain to be optimized for its specific function, enabling efficient identification and tracking of access events without the performance degradation that occurs in traditional single-chain structures as they lengthen.
2Adaptability or versatility
If a traditional blockchain structure is used, then the blockchain can store mixed block types, but the structure becomes inefficient for anomaly detection and tracking when the blockchain becomes long
Solution Approach 1:
The patent separates different block types into dedicated chains: administration blocks on the administration chain, login blocks on the login chain, and user access blocks on the user access chain. This segmentation makes anomaly detection more efficient because each chain contains only relevant event types, reducing the search space and enabling faster identification of anomalies compared to searching through a mixed-chain structure.
Solution Approach 2:
The patent introduces hash pointers as intermediaries that link blocks across different chains while maintaining their specialized structures. Each block contains a hash pointer to the previous block in its own chain, and additional hash pointers that reference related blocks in other chains, enabling efficient tracking and cross-validation without merging all block types into a single inefficient chain.

AI summary
A plurality of different types of resource access events are identified. For example, a resource access event may be an administration event where a user is given certain access rights to view/modify a resource, such as, a database record. A plurality of blocks are generated, where each block is associated with an individual one of the plurality of different types of resource access events. The plurality of blocks are added to a first resource access blockchain. The blockchain can be used to track the various types of resource access events.
