STORAGE MEDIUM, CONSIDERATION DISTRIBUTION METHOD, AND INFORMATION MANAGEMENT DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240056304 titled 'STORAGE MEDIUM, CONSIDERATION DISTRIBUTION METHOD, AND INFORMATION MANAGEMENT DEVICE
Simplified Explanation
The patent application describes a program that manages information in a supply chain by acquiring, concealing, registering, generating proof, and notifying processes of consideration amounts.
- Acquiring a first cumulative consideration amount from an upstream process in a supply chain to a first process
- Generating a consideration amount commitment by concealing the first cumulative consideration amount using a random number
- Registering the consideration amount commitment in a blockchain
- Generating a consideration amount proof that is a zero knowledge proof validating the second cumulative consideration amount without revealing it
- Notifying the second process of the second cumulative consideration amount, the random number, and the consideration amount proof
---
- Potential Applications

Original Abstract Submitted
a storage medium storing an information management program that causes a computer to execute a process that includes acquiring a first cumulative consideration amount from a most upstream process in a plurality of processes included in a supply chain to a first process; generating a consideration amount commitment by concealing the first cumulative consideration amount by using a random number; registering the consideration amount commitment in a blockchain; generating a consideration amount proof that is a zero knowledge proof that proves validity of the second cumulative consideration amount without disclosing the second cumulative consideration amount; and notifying the second process of the second cumulative consideration amount, the random number, and the consideration amount proof.
