Blockchain Access Control via Branch Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current centralized databases face challenges with data redundancy, security, and accessibility, particularly in supply-chain management across multiple organizations, where traditional databases lack the ability to efficiently manage access control and data sharing securely across a dynamic subset of organizations.
Innovation Solution
Implementing a blockchain-based decentralized database system that utilizes smart contracts and branch prediction algorithms to determine access control, enabling secure and efficient data sharing and access management across a network of organizations by traversing supply-chains and resolving forks based on confidence levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized database is used to store and maintain data at one location, then data redundancy is minimized and security control is simplified, but accessibility and data sharing across multiple organizations in supply-chain are limited
Solution Approach 1:
The patent segments the centralized database into a distributed ledger system where data is replicated across multiple nodes/organizations. Each organization maintains a copy of the ledger, enabling simultaneous access and collaboration while preserving data integrity through cryptographic hashing and consensus mechanisms.
Solution Approach 2:
The patent implements nested structures where blocks contain transactions and are linked through cryptographic hashes to form chains. Smart contracts are nested within the blockchain structure, enabling layered access control and data organization that maintains security while enabling selective sharing across organizational boundaries.
2Adaptability or versatility
If data is shared across multiple organizations in a supply-chain, then accessibility and collaboration are improved, but data security and access control management become more complex
Solution Approach 1:
The patent implements self-service access control through smart contracts that automatically enforce access policies based on predefined rules. The system autonomously manages permissions, validates transactions, and controls data visibility without requiring manual intervention from central administrators, thereby simplifying access control management in multi-organization environments.
Solution Approach 2:
The patent incorporates feedback mechanisms where the distributed ledger continuously validates transactions and updates access control states across all nodes. The system provides real-time feedback on data access requests, transaction validity, and permission states, enabling automatic adjustment of access control without complex manual management.
3Ease of operation
If traditional databases are used for supply-chain management, then ease of management is maintained, but the ability to efficiently manage access control and data sharing securely across dynamic subsets of organizations is insufficient
Solution Approach 1:
The patent implements dynamic access control through programmable smart contracts that can adapt permissions and data visibility based on changing supply-chain conditions. Access rights, data sharing policies, and transaction validation rules can be dynamically modified by executing new smart contract code on the distributed ledger, enabling flexible response to evolving organizational needs without sacrificing management simplicity.

AI summary
An example operation includes one or more of detecting a fork in a supply-chain by a modeling node, resolving, by the modeling node, a branch prediction to determine a likely access control, generating, by the modeling node, a range of information based on a branch confidence level, and responsive to the resolution of the branch prediction, revoking access from a document or granting a greater access to the document based on the range.
