Data file transfer balance and control system

Data file transfer balance and control system

Short answer question

What is data file transfer balance and control (B&C)? **Answer:** Data file transfer balance and control (B&C) is a process that ensures accurate, complete and timely data transmission between systems. It is used to verify the accuracy, completeness and timeliness of data transmission.

What are the problems with traditional B&C systems? **Answer:** Traditional systems rely on third-party intermediaries for verification, which increases development time, design complexity and failure points. In addition, third-party systems may not be completely tamper-proof and pose security risks.

How does the B&C system proposed in this patent solve the problems of traditional systems? **Answer:** The system uses blockchain technology to achieve decentralized B&C through peer-to-peer data transmission and smart contracts. The immutability and transparency of blockchain improve the security and efficiency of the system.

What role does blockchain play in the B&C system? **Answer:** As a distributed database, blockchain stores data file transfer confirmation and confirmation information and executes smart contracts for verification. The immutability of blockchain ensures the reliability of records.

What is a hash function and how is it used in the B&C system? **Answer:** A hash function converts data of arbitrary length into a hash value of fixed length. In the B&C system, the sender and receiver use the same hash function to generate the hash value of the data file, and verify the file integrity by comparing the hash value.

What is a smart contract and how is it used in the B&C system? **Answer:** A smart contract is an automatically executed contract stored on the blockchain. In the B&C system, smart contracts are used to compare the file hash values ​​of the sender and receiver, and automatically identify unbalanced file transfer events.

What is an API and how is it used in the B&C system? **Answer:** An API (application programming interface) allows different software systems to interact. In the B&C system, the sender and receiver use the API to write file transfer confirmation and confirmation information to the blockchain.

What role does the monitoring device play in the B&C system? **Answer:** The monitoring device reads the data on the blockchain, identifies unbalanced file transfer events, and generates an alarm or trouble ticket to notify relevant personnel.

What are the advantages of a blockchain-based B&C system compared to traditional systems? **Answer:** The blockchain-based B&C system has the advantages of decentralization, tamper-proof, high transparency, and fast verification speed, which can simplify B&C operations and improve efficiency and security.

What application scenarios are suitable for the B&C system proposed in this patent? **Answer:** The system is suitable for scenarios that require highly secure and reliable data transmission, such as credit applications on e-commerce platforms, financial transaction records, etc.

Key Glossary

Term Definition Data File Transfer Balance and Control (B&C) The process of ensuring accurate, complete and timely data transmission between systems. Blockchain Distributed database that records transactions in a secure, transparent and tamper-proof manner. Smart Contract An automatically executed contract stored on the blockchain that defines the rules for data file transfer verification. Hash function An algorithm that converts data of arbitrary length into a fixed-length hash value, used to verify data integrity. API (Application Programming Interface) An interface that allows different software systems to interact, used to communicate with the blockchain. A system where the sender initiates the data file transfer. A system where the receiver receives the data file. A system where monitoring equipment monitors the blockchain to identify unbalanced file transfer events. Data file transfer confirmation The information written to the blockchain by the sender after sending the data file, including metadata such as the file hash value and timestamp. Data file transfer confirms the information that the receiver writes to the blockchain after receiving the data file, including metadata such as file hash value and timestamp. Unbalanced file transfer event The file hash values ​​of the sender and receiver do not match, indicating that an error occurred during the data transfer process.
