Token Management System for Intangible Asset Licensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing intangible assets face challenges in setting reasonable prices, protecting confidential information, and efficiently managing licenses, leading to difficulties in secure and transparent ownership transfer.
Innovation Solution
A token management system utilizing a distributed ledger, specifically a blockchain, generates non-fungible tokens associated with product identifiers, manages public and private keys for licensing, and enables secure transaction processing, ensuring privacy protection and fault tolerance through decentralized networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central management server group integrally manages distribution of intangible assets, then license management can be performed, but the selling price cannot be appropriately evaluated by the market and confidential information may be leaked
Solution Approach 1:
The patent divides the centralized management system into distributed autonomous nodes (licensors, licensees, and smart contracts) on a blockchain network. Each participant manages their own assets and licenses independently through cryptographic keys, eliminating the single-point control vulnerability while maintaining license management functionality through decentralized consensus.
Solution Approach 2:
The patent introduces smart contracts as intermediary automated agreements that enforce license terms and pricing rules without human intervention. These self-executing contracts on the blockchain mediate between licensors and licensees, ensuring transparent pricing evaluation and secure information handling without exposing sensitive data.
2Ease of operation
If traditional license management systems are used, then distribution can be controlled, but transparency and privacy protection cannot be simultaneously achieved
Solution Approach 1:
The patent applies different levels of transparency to different participants and data types. Public blockchain data provides full transparency for license transactions and pricing, while private keys and sensitive asset details remain locally secured on individual devices. This selective transparency approach enables distribution control without compromising privacy.
Solution Approach 2:
The patent replaces traditional mechanical authentication and control systems with cryptographic mechanisms. Public-private key pairs enable secure identity verification and authorization without exposing personal information, while cryptographic hashing protects sensitive data while allowing verification of its integrity.
3Device complexity
If centralized systems manage intangible assets, then management processes can be simplified, but fault tolerance and system reliability are reduced
Solution Approach 1:
The patent segments the management system into multiple independent nodes distributed across the network. Each node maintains its own copy of the ledger and can independently validate transactions, eliminating single-point failures. The system continues to function even if individual nodes fail, providing inherent fault tolerance.
Solution Approach 2:
The patent implements continuous feedback loops through the consensus mechanism where nodes constantly verify and validate transactions against the ledger state. This real-time verification and automatic correction of inconsistencies ensures system reliability and maintains data integrity even under adverse conditions.

AI summary
A token management system includes a generation unit that generates a non-fungible token associated with a product identifier in a distributed ledger, a management unit that associates the non-fungible token with a first public key, and a second public key for licensing processing in the distributed ledge, and a transfer unit that performs transaction processing of changing the first public key associated with the non-fungible token on the basis of a first private key is realized.
