Blockchain Information Transmission with Hash Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for information transmission face challenges in ensuring encrypted and tamper-proof data exchange while maintaining control over the information by the transmitter and ensuring that only the receiver can access the information.
Innovation Solution
A method utilizing a blockchain system where a transmission terminal generates a data record with a hash value, encrypts the information using the receiver's public key, and transmits it through the blockchain, ensuring tamper-proof and secure information exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored in a central database or service provider system, then data access and management are simplified, but data security and tamper-proof verification are compromised
Solution Approach 1:
The patent segments the centralized data storage system into a distributed blockchain network where data is divided across multiple nodes. Each node maintains a copy of the data structure, eliminating the single point of failure inherent in centralized systems while maintaining ease of access through the distributed network.
Solution Approach 2:
The patent introduces cryptographic hash functions and digital signatures as intermediaries between the data storage and verification processes. These mathematical mechanisms enable tamper-proof verification without requiring trust in any single service provider, resolving the contradiction between simplified access and reliable verification.
2Object-affected harmful factors
If data is encrypted and stored with a service provider, then data transmission security is improved, but control over the information by the transmitter and verification by the receiver are lost
Solution Approach 1:
The patent implements preliminary actions by having the transmitter generate and register cryptographic keys and data hashes in the blockchain before actual data transmission. This preliminary registration in the immutable ledger enables the transmitter to retain control and the receiver to verify information without relying on the service provider's continued availability.
Solution Approach 2:
The patent establishes a feedback mechanism where the blockchain network provides verification feedback to both transmitter and receiver. The immutable ledger records and confirms data integrity, enabling parties to verify information independently without needing to trust the service provider, thus maintaining control while ensuring security.
3Device complexity
If data is stored in a centralized system, then data management is simplified, but the system becomes vulnerable to single-point failures and border limitations
Solution Approach 1:
The patent creates a universal blockchain infrastructure that serves multiple functions simultaneously: data storage, verification, security, and cross-border transmission. This multi-functional system replaces multiple specialized centralized systems, maintaining simplicity while eliminating single-point failures and border limitations through its distributed, borderless nature.
Data Source
AI summary
A method for information transmission. In a first transaction step, a first data record is generated by the transmission terminal, and the first data record is transferred to a blockchain. In a first verification step, the first data record in the blockchain is verified and stored as a first verified data record. In a second transaction step, a second data record is generated by the receiver terminal, and the second data record is transferred to the blockchain. In a second verification step, the second data record in the blockchain is verified and stored as a second verified data record. In a data encryption step, encrypted data are generated by the transmission terminal. In a transmission step, encrypted data are transmitted to the receiver terminal. In a data decryption step, a piece of electronic information is made accessible to the receiver.
