Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data analytics systems for video, voice, and data services face challenges in securely managing access to diverse datasets, including proprietary and privacy-sensitive information, across various devices and networks.
Innovation Solution
The implementation of a blockchain-based enforcement system for data access control, where a permissioned blockchain is used to manage access rights based on stakeholder endorsements, ensuring secure and transparent data access transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized data access control systems are used, then data access management is simple and centralized, but security and reliability are insufficient for distributed data environments
Solution Approach 1:
The patent introduces a blockchain-based intermediary layer that mediates between data requestors and data sources. The blockchain ledger acts as a trusted mediator that records and verifies access control transactions without requiring a centralized authority, thereby improving reliability while distributing the system architecture
Solution Approach 2:
The access control system is segmented into multiple independent components: data sources, data requestors, blockchain nodes, and smart contracts. This segmentation allows each component to operate independently with defined responsibilities, improving system reliability through fault isolation while managing complexity through modular design
2Adaptability or versatility
If data access control is implemented across multiple distributed devices and networks, then data sharing capability is improved, but security management becomes more complex and vulnerable
Solution Approach 1:
The blockchain-based access control system provides universal functionality that works across diverse data sources, requestors, and networks. The smart contract framework enables a single access control policy to be applied universally across multiple devices and networks, enhancing data sharing capability while standardizing security management to reduce complexity
Solution Approach 2:
The blockchain ledger serves as a universal intermediary that standardizes authentication and authorization processes across distributed devices. By providing a common trusted platform, it simplifies security management while enabling broad data sharing across different networks and devices
3Productivity
If proprietary and privacy-sensitive data is collected and analyzed, then data analytics capability is enhanced, but data privacy protection requirements increase
Solution Approach 1:
The system implements preliminary anti-action by establishing access control policies and permissions before data analytics operations occur. Smart contracts pre-define which entities can access specific data, preventing unauthorized access and privacy violations before they can happen during data collection and analysis processes
Solution Approach 2:
The blockchain-based access control system acts as an intermediary layer between data analytics systems and sensitive data sources. It enables data analytics capability by allowing authorized access to proprietary and privacy-sensitive data while simultaneously protecting privacy by filtering and controlling what data can be accessed and by whom
Data Source
AI summary
A method is provided that includes receiving a data request from a requesting device requesting data from a data source, looking up, in a blockchain ledger, a transaction corresponding to the data request to validate the data request, forwarding the validated data request to a data server, receiving a data response from the data server in response to the data request, wherein the data response comprises the requested data from the data source, and forwarding the data response to the requesting device.
