Token-Based Private Data Exchange for Ownership-Controlled Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to balance data privacy and access control, allowing unauthorized access while compromising data ownership.
Innovation Solution
Implementing data access tokens (DATs) that separate data ownership from access rights, using non-fungible tokens (NFTs) to manage and control access to private data through a decentralized system, ensuring data owners retain control while allowing authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data access control is implemented through traditional authentication mechanisms, then access security is improved, but data ownership control and flexibility deteriorate
Solution Approach 1:
The patent segments access control into two independent components: authentication (proving identity) and authorization (granting access rights). This is achieved by separating the authentication mechanism from the data ownership control, allowing each to be optimized independently. The authentication layer handles security while the authorization layer manages ownership flexibility through token-based control.
Solution Approach 2:
The patent introduces a token-based intermediary layer between data owners and access requests. Tokens act as mediators that carry authorization information, enabling flexible access control without direct exposure of ownership relationships. This intermediary layer allows the system to maintain both security and adaptability by managing access rights through token exchange rather than direct authentication.
2Ease of operation
If centralized access control systems are used, then access management is simplified, but system complexity and trust requirements increase
Solution Approach 1:
The patent uses token copies to distribute access rights across multiple systems and devices. Instead of maintaining a centralized access control database, the system creates and circulates token copies that carry authorization information. This allows access management to be simplified at the user level while distributing the complexity across the token validation layer in various systems.
Solution Approach 2:
The patent replaces centralized mechanical access control systems with a digital token-based system. Traditional centralized databases and authentication servers are substituted with cryptographic tokens that can be validated across distributed systems. This substitution reduces trust requirements in centralized authorities while maintaining ease of access management through token-based protocols.
3Productivity
If data is made accessible to multiple parties, then data utility is improved, but data privacy and security deteriorate
Solution Approach 1:
The patent applies local quality by granting different access rights to different token holders based on their specific needs. Instead of uniform access control, the system creates tokens with customized authorization attributes, allowing each data consumer to access only the specific data they need. This maintains data utility for multiple parties while preserving privacy by limiting access scope.
Solution Approach 2:
The patent introduces dynamic access control through time-limited and condition-based tokens. Access rights are not static but can be adjusted based on temporal constraints, usage conditions, and data context. This allows the system to maximize data utility by enabling flexible access while mitigating privacy risks through dynamic restriction of access windows and conditions.

AI summary
Systems, apparatus, and methods of managing access to private data via tokens are disclosed. The disclosed techniques provide for constructing digital tokens that represent a right-to-access private data where the tokens can be managed as individual objects. Further, such digital access tokens (DATs) can be recorded on a notarized ledger, a blockchain for example. Additionally, the rights-to-access can be embodied as a non-fungible token (NFT), which could further include support for establishing homomorphic encryption workspaces in which private data can be accessed or manipulated without exposing the private data.
