Description

Technical Field

[0001] This invention relates to the field of e-commerce data security technology, specifically a blockchain-based method and system for preventing tampering with e-commerce transaction data. Background Technology

[0002] Existing e-commerce transaction data is generally stored in a centralized database: transaction data is centrally stored in the platform database, and data protection is achieved through backup and log auditing, but there is a risk of single point of tampering.

[0003] For the protection of transaction data in e-commerce, digital signature technology is generally used: digital signatures (such as RSA) are attached to key data, but it can only verify integrity and cannot prevent the original data from being tampered with. Summary of the Invention

[0004] The technical objective of this invention is to address the above-mentioned shortcomings by providing a blockchain-based method and system for preventing tampering of transaction data in e-commerce platforms. This method solves the problems of easy tampering, poor traceability, and high auditing costs associated with transaction data on e-commerce platforms. It enables transparent recording of transaction data throughout the entire process, real-time tamper-proof verification, and low-cost, efficient auditing, significantly improving the security and credibility of e-commerce data.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A blockchain-based method for preventing tampering of transaction data in e-commerce platforms. This method stores transaction data through a distributed ledger, combines smart contracts to automatically execute data verification and auditing processes, and utilizes asymmetric encryption and consensus mechanisms to ensure data immutability.

[0007] The distributed ledger stores transaction data: transaction data is generated into hash values ​​by timestamps and written into the blockchain to form an irreversible data chain;

[0008] The smart contract can automatically perform data hash verification and generate tampering alarms.

[0009] This method, based on blockchain distributed storage, smart contracts, consensus mechanisms, and data encryption technology, achieves a real-time, low-cost, and scalable blockchain anti-tampering solution. It solves the problems of easy tampering, difficult auditing and traceability, and low credibility of e-commerce transaction data, and is suitable for anti-tampering management, auditing and traceability, and trusted evidence storage scenarios of e-commerce platform transaction data.

[0010] Furthermore, the distributed ledger stores transaction data using asymmetric encryption: users and merchants use key pairs (ECDSA) to sign, ensuring the data source is trustworthy.

[0011] Furthermore, the transaction data includes order, payment, and logistics data.

[0012] Furthermore, smart contract verification includes:

[0013] Automated contract auditing: Deploy on-chain smart contracts to verify the consistency between new transaction data and historical block hashes in real time, and trigger tampering alarms when inconsistencies occur;

[0014] Dynamic auditing strategy: Supports custom rules.

[0015] Furthermore, the custom rules include mandatory secondary verification for large transactions.

[0016] Furthermore, the method also includes a cross-chain auditing interface, which connects the e-commerce business system with the blockchain network through an oracle to achieve automated data synchronization and external auditing.

[0017] Furthermore, this method provides a user interface for inputting transaction data and visualizing audit results.

[0018] This invention also claims protection for a blockchain-based e-commerce transaction data anti-tampering system, comprising:

[0019] User interface layer: Provides a visual interface for transaction data input and audit results;

[0020] The core layer of the blockchain includes a distributed ledger, a smart contract engine, and a consensus node network, used to store and verify transaction data in real time.

[0021] Audit module: Automatically performs data hash verification through smart contracts and generates tampering alerts;

[0022] Business adaptation layer: Connects to the e-commerce order system via an oracle to achieve automated data synchronization;

[0023] The system uses the methods described above to prevent tampering with the transaction data of the online store.

[0024] This invention also claims a blockchain-based device for preventing tampering with transaction data in an online marketplace, characterized in that it comprises: at least one memory and at least one processor;

[0025] The at least one memory is used to store a machine-readable program;

[0026] The at least one processor is used to call the machine-readable program to implement the above method.

[0027] The present invention also claims a computer-readable medium storing computer instructions that, when executed by a processor, implement the above-described method.

[0028] Compared with existing technologies, the blockchain-based method and system for preventing tampering of e-commerce transaction data of the present invention has the following advantages:

[0029] 1. Tamper-proof: Data is guaranteed to be immutable through a blockchain hash link structure and consensus mechanism.

[0030] 2. Real-time auditing: Automatic verification is achieved through smart contracts.

[0031] 3. Reduced costs: Decentralized storage can reduce reliance on third-party evidence storage.

[0032] 4. Scalability: Supports dynamic addition of business nodes, and no system reconstruction is required when adding new transaction types. Attached Figure Description
