Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing blockchain technologies struggle to manage information regarding the beneficiary of consideration for rights, particularly when the attribution of the right differs from the beneficiary, making it difficult to record and protect sensitive distribution information.

Innovation Solution

A program and information processing device that generate and manage divisible tokens on a blockchain, incorporating benefit ratio information and distribution agreements, using smart contracts to ensure legitimacy and confidentiality, and encrypting data to protect beneficiary privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blockchain technology is used to record right management information, then transparency and immutability are improved, but the ability to protect beneficiary privacy and sensitive distribution information deteriorates

Engineering Contradiction:

Improvetransparency and immutabilityVSAvoidprivacy exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the token into divisible units that can be separately allocated to different beneficiaries. Each token fraction represents a specific benefit ratio, allowing the system to record distribution information in granular segments rather than as a single opaque unit. This segmentation enables transparent tracking of each fraction's allocation while protecting individual beneficiary identities through cryptographic techniques.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a smart contract as an intermediary layer between the blockchain and beneficiary information. The smart contract holds and manages the divisible tokens, controlling their distribution according to predetermined rules. This intermediary mechanism allows the blockchain to maintain transparency and immutability for token transactions while the smart contract logic protects sensitive beneficiary details from direct exposure on the public ledger.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If divisible tokens are issued to manage benefit ratios, then precision in managing consideration distribution is improved, but system complexity increases

Engineering Contradiction:

Improvebenefit ratio management precisionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the fundamental parameter of token divisibility, allowing tokens to be divided into smaller units with precise fractional values. This enables exact representation of benefit ratios (e.g., 0.35, 0.65) rather than requiring integer allocations. The system uses cryptographic tokens with embedded value representations that can be mathematically divided and recombined, providing precision in benefit ratio management while the underlying blockchain infrastructure handles the computational complexity.

AI summary

To manage information regarding a beneficiary of a consideration for rights on a blockchain. A program for causing a computer to function as: an issuance information generation unit that generates information for issuing a divisible token that includes information regarding a benefit ratio of a consideration and operates on a blockchain; and a division information generation unit that generates information for issuing the token divided on the basis of distribution information of the consideration based on an agreement to a beneficiary of the consideration.
