Description

Technical Field

[0001] The present invention belongs to the field of digital advertising data security technology, and specifically refers to an advertising data security verification method based on blockchain. Background Art

[0002] With the popularity of the Internet and mobile devices, the digital advertising industry has experienced explosive growth, which has led to an increased demand for more efficient and secure advertising technologies. Users are increasingly concerned about privacy, especially in the wake of scandals over data breaches and improper data use. Therefore, technologies that protect user data and privacy, such as anonymization and encryption, have become increasingly important. Click fraud, traffic hijacking, and fake traffic have become a major problem in the advertising industry, which has prompted the development of technologies designed to detect and prevent these fraudulent behaviors. Blockchain technology provides a new method for data management and verification. Its tamper-proof and transparent characteristics provide new solutions for advertising security. Technologies for blockchain-based advertising data security verification methods are emerging.

[0003] In the field of digital advertising, data security and verification is an important issue. Existing advertising data verification methods rely on centralized databases, which makes data vulnerable to tampering and attacks. Summary of the invention

[0004] In order to overcome the problem that the advertising data verification method in the prior art relies on a centralized database, which makes the data vulnerable to tampering and attacks, the present invention designs an advertising data security verification method based on blockchain, which can effectively solve the above technical problems.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a blockchain-based advertising data security verification method, comprising the following steps:

[0006] Step S1: Collect data during the advertising process;

[0007] Step S2: Encapsulating the collected data into a data packet and generating a unique identifier for the data packet;

[0008] Step S3: digitally sign the data packet using a private key;

[0009] Step S4: Send the digitally signed data packet to a target node in the blockchain network;

[0010] Step S5: Verifying the validity of the signature data packet through the consensus mechanism in the blockchain network;

[0011] Step S6: storing the verified signature data packet in the distributed ledger of the blockchain;

[0012] Step S7: Utilize smart contracts to automatically execute payment and settlement of advertising fees.

[0013] Preferably, the step S1 includes the following sub-steps:

[0014] Step S1-1: define the scope of data collection;

[0015] Step S1-2: Collect data in real time or periodically through the API interface of the advertising platform or third-party data service provider;

[0016] Step S1-3: Clean and preprocess the collected data to remove invalid or redundant information.

[0017] Preferably, step S2 includes the following sub-steps:

[0018] Step S2-1: Encapsulate the cleaned data into a standard data packet format according to the data structure and format requirements;

[0019] Step S2-2: Use a hash function to perform hash processing on the content of the data packet to generate a hash value of a fixed length as a unique identifier of the data packet.

[0020] Preferably, the hash function used in step S2-2 is SHA-256.

[0021] Preferably, step S3 includes the following sub-steps:

[0022] Step S3-1: Retrieve a private key associated with an advertiser or an advertising platform from a private key library;

[0023] Step S3-2: Use the private key to digitally sign the unique identifier of the data packet to generate signature information;

[0024] Step S3-3: Attach the signature information to the data packet to form a complete signature data packet.

[0025] Preferably, step S4 includes the following sub-steps:

[0026] Step S4-1: Select one or more nodes in the blockchain network as target nodes;

[0027] Step S4-2: sending the signature data packet to the selected target node via a P2P network protocol;

[0028] Step S4-3: The target node receives the signature data packet and performs preliminary verification, and then forwards it to other nodes in the blockchain network.

[0029] Preferably, step S5 includes the following sub-steps:

[0030] Step S5-1: The nodes in the blockchain network verify the received signature data packet according to the consensus algorithm;

[0031] Step S5-2: Verify the integrity of the signed data packet, the validity of the signature, and the compliance of the data content;

[0032] Step S5-3: When the consensus condition is reached, the signature data package is deemed valid.

[0033] Preferably, step S6 includes the following sub-steps:

[0034] Step S6-1: Pack the verified valid signature data packet and related information into a block;

[0035] Step S6-2: Linking the new block to the previous block through the chain structure of the blockchain to form an unalterable distributed ledger;

[0036] Step S6-3: Each target node in the blockchain network will synchronously update its local copy of the ledger.

[0037] Preferably, the step S7 includes the following sub-steps:

[0038] Step S7-1: deploying a smart contract on the blockchain to define payment conditions and settlement rules for advertising fees;

[0039] Step S7-2: When the payment conditions are met, the smart contract automatically triggers the payment process;

[0040] Step S7-3: deducting the corresponding fee from the account of the advertiser or the advertising platform and transferring it to the account of the media or the advertising platform;

[0041] Step S7-4: Record the payment and settlement details and save them on the blockchain for subsequent audit and inquiry.

[0042] The beneficial effects of the blockchain-based advertising data security verification method of the present invention are as follows: by storing advertising data in the distributed ledger of the blockchain instead of a single centralized database, the risk of single point failure is eliminated; the distributed nature of the blockchain means that the data is stored on multiple nodes in the network, and even if a node is attacked or fails, the data will not be lost. The advertising data is encapsulated into a data packet before being uploaded to the chain, and a unique identifier is generated using the SHA-256 hash function. This step ensures the integrity and consistency of the data. Any tampering with the data will cause a change in the hash value, which will be detected by the blockchain network; the data packet is digitally signed using a private key to verify the source of the data and prevent denial of responsibility. The digital signature ensures the security of the data during transmission, and only entities with the corresponding private key can generate a valid signature; the consensus mechanism in the blockchain network ensures that all nodes reach consensus on the validity of the data packet. This process involves multiple nodes in the network verifying the data packet. Only when the majority of nodes pass the verification, the data packet is considered valid, thereby enhancing the security and trust of the data. Once the data packet is verified and added to the blockchain, it forms an unalterable record. The chain structure and encryption algorithm of the blockchain ensure that once the data is written into the block, it cannot be changed or deleted. The payment and settlement of advertising fees are automatically executed by smart contracts, reducing the possibility of manual intervention and errors. The automatic execution characteristics of smart contracts improve the efficiency and transparency of the settlement process. Through the encryption technology of the P2P network protocol and blockchain, the security of data in the transmission process is enhanced. The preliminary verification of the target node and the forwarding mechanism of the data packet increase the defense against malicious behavior. The transparency of the blockchain allows all participants to view and verify the advertising data, and the unalterable ledger record provides a reliable audit trail. This helps to improve the trust of advertisers, publishers and third parties in advertising data. BRIEF DESCRIPTION OF THE DRAWINGS
