Blockchain Contract Terminal Using Digital Content Original Confirmation Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blockchain technology lacks a means to confirm the authenticity and integrity of contracts stored on it, as only transaction timestamps are recorded, making it difficult to verify the originality and potential tampering of contracts.
Innovation Solution
A blockchain type contract terminal and method using a digital contents original confirmation key, which includes modules for inputting contract terms, collecting real-time position information, creating contracts, obtaining a digital contents original confirmation key, encrypting contracts, and storing them on a blockchain, ensuring the authenticity and security of contracts by combining position information with contract data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If only transaction timestamp is stored on blockchain, then storage efficiency is improved, but contract authenticity verification capability deteriorates
Solution Approach 1:
The patent extracts the contract hash value from the complete contract data and stores only the hash on the blockchain, while keeping the full contract data in off-chain storage. This extraction approach maintains storage efficiency while enabling authenticity verification through hash comparison.
Solution Approach 2:
The patent introduces a contract hash value as an intermediary element that connects the stored contract data with the blockchain record. This hash acts as a mediator that enables verification without requiring storage of the entire contract on the blockchain.
2Reliability
If position information collection module is added, then contract security is improved, but device complexity increases
Solution Approach 1:
The patent integrates the position information collection module into the existing terminal device, making it a multi-functional component that serves both location tracking and contract authentication purposes. This universal approach adds security functionality without requiring completely separate systems.
Solution Approach 2:
The terminal device automatically collects position information and integrates it with contract data without requiring manual intervention. The system self-services by autonomously gathering location data and combining it with contract terms for enhanced security.

AI summary
Disclosed are blokchain type contract terminal and method using a digital contents original confirmation key. There are provided: an input module that is inputted with a contract term regarding an object of contract; a position information collection module that collects, in real time, position information of the object at the time of contract; a contract creation module that creates a contract by using the contract term inputted by the input module and the position information at the time of contract collected in real time by the position information collection module; a digital contents original confirmation key interface module that provides the contract term inputted by the input module and the position information at the time of contract collected in real time by the position information collection module to a contents initializer and an international authentication adjustment server, and receives a digital contents original confirmation key from the contents initializer or the international authentication adjustment server; a digital contents original contract creation module that combines the digital contents original confirmation key received at the digital original confirmation key interface module with the contract created at the contract creation module to create a digital contents original contract; a blockchain creation module that encrypts the contract created by the digital contents original contract creation module to create a blockchain; and a blockchain distributed storage control module that transmits the blockchain created at the blockchain creation module to another terminal in a P2P manner for storing on a network in a distributed manner.
