Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tokenization techniques fail to adequately protect sensitive data from unauthorized access and exposure, particularly in decentralized systems, where mapping data is often compromised, leading to potential security breaches.
Innovation Solution
Implement decentralized tokenization with mapping data devoid of sensitive information, using index-key pairs to generate tokens, and ensure isolation of computing resources to enhance security and minimize single points of failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized tokenization is used to protect sensitive data, then data security is improved, but single points of failure are created and processing delays increase
Solution Approach 1:
The patent divides the centralized tokenization system into multiple decentralized tokenization services distributed across different computing devices. Each service maintains a portion of the mapping data, eliminating the single point of failure while enabling parallel processing to reduce delays.
Solution Approach 2:
The patent introduces a distributed hash table (DHT) as an intermediary structure that enables decentralized nodes to locate and access mapping data without centralized coordination. This mediator allows direct peer-to-peer communication while maintaining security and reducing processing bottlenecks.
2Ease of operation
If mapping data is retained to facilitate deriving sensitive data from tokens, then data accessibility is improved, but security is worsened due to exposure of sensitive information
Solution Approach 1:
The patent segments the mapping data into distributed portions stored across multiple decentralized nodes. Each node holds only a fragment of the complete mapping, making it computationally infeasible to reconstruct sensitive data even if individual nodes are compromised.
Solution Approach 2:
The patent implements location-based access control where each decentralized node can only access mapping data relevant to its specific jurisdiction or domain. This ensures that even with access to mapping data, unauthorized derivation of sensitive information is prevented through cryptographic safeguards and access restrictions.
3Reliability
If decentralized tokenization is implemented to eliminate single points of failure, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal decentralized tokenization protocol that can be deployed across heterogeneous computing devices and networks. The standardized interface and communication protocols allow existing infrastructure to be utilized, reducing the need for specialized components and simplifying deployment despite the distributed architecture.
Solution Approach 2:
The patent uses cryptographic hashing to create verified copies of mapping data fragments across multiple nodes. These copies are automatically synchronized and validated using hash functions, ensuring data integrity without requiring complex manual replication mechanisms.

AI summary
Systems and methods for providing decentralized tokenization with mapping data devoid of sensitive data. A node receives a set of index-key pairs generated by a randomization service external to the node. Each index-key pair in the set of index-key pairs defines a particular index value mapped to a particular random key value. The node creates a mapping structure using the set of index-key pairs. Data-in-transit comprising sensitive data is received. A tokenization service of the node generates a token for the sensitive data using the mapping structure.
