Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and specifically relates to a geophysical data communication method, system, device and medium based on blockchain. Background Art

[0002] At present, geophysical data communication widely relies on traditional centralized network architecture. After the data is transmitted from the acquisition equipment to the remote server or cloud, it is centrally stored and processed before being distributed to relevant users. Although this method has certain efficiency in data management and analysis, its technical limitations are becoming increasingly apparent, especially in terms of data credibility, security and efficiency. There are the following significant problems: 1. Insufficient data credibility: Geophysical data usually involves a large number of sensor devices and remote collection points. There is a risk of data tampering during the collection, transmission and storage process. Traditional centralized management methods rely on single-point trust and are difficult to provide full-link data traceability and integrity assurance. Data falsification or loss is difficult to detect and correct. 2. Security risks in the transmission process: In existing technologies, data is vulnerable to man-in-the-middle attacks, interception or tampering during transmission; especially when it involves transmission across a network environment, data encryption measures are insufficient or overly dependent on single-point protection, making it difficult to completely resist security risks; 3. Single point failure problem of centralized architecture: Traditional centralized data communication methods are highly dependent on central servers. Once the central server fails, the entire data transmission and processing link may be interrupted, seriously affecting the efficiency of geophysical exploration and analysis. 4. Inefficient data sharing: Geophysical data usually needs to be shared among multiple parties, but the data sharing process under existing technologies relies on central institutions to allocate permissions and transfer data, which is inefficient and may cause trust issues among participants. 5. Insufficient auditing and transparency: In geophysical exploration, the data verification and auditing process between different institutions is complicated. Traditional technology cannot automatically achieve full record keeping and openness and transparency, which increases the cost and difficulty of data credibility review. Summary of the invention

[0015] The accompanying drawings are used to provide a further understanding of the embodiments of the present invention and constitute a part of the specification. Together with the following specific implementations, they are used to explain the embodiments of the present invention, but do not constitute a limitation on the embodiments of the present invention.

DETAILED DESCRIPTION

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0017] Embodiment 1 Figure 1 FIG. 1 is a flow chart of a geophysical data communication method based on blockchain provided by an embodiment of the present invention. Figure 1 As shown, this embodiment provides a geophysical data communication method based on blockchain, which is applied to a data acquisition device. In this embodiment, there are multiple data acquisition devices, and each data acquisition device executes the following method, which includes: Step S10: The data acquisition device acquires geophysical data, and preprocesses the geophysical data to obtain preprocessed geophysical data, wherein the preprocessing includes: interpolation processing, detrending, coordinate transformation, and filtering processing; secondly, the preprocessing also includes: data segmentation, after the geophysical data is segmented, a plurality of data blocks are obtained, each data acquisition device segments the acquired geophysical data into a plurality of data blocks, each data block contains a certain amount of geophysical data, and the plurality of data blocks are used as preprocessed geophysical data.

[0018] Step S20: The data acquisition device encrypts the preprocessed geophysical data based on an encryption algorithm to obtain encrypted data; wherein the encryption algorithm may be the following: AES (Advanced Encryption Standard) algorithm, the AES algorithm provides key lengths of 128, 192, and 256 bits; The CAST-128 (Cipher-based Authentication Mode) algorithm supports variable key lengths, which can be 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120, or 128 bits. This allows the algorithm to adjust the key length according to specific needs to provide different levels of security.

[0019] In this embodiment, the encrypted data output by a data acquisition device includes multiple encrypted data blocks.

[0020] Step S30: The data collection device generates a digital summary (Hash) based on the encrypted data. The digital summary is unique and can be used as a basis for data integrity verification.

[0021] Step S40: The data collection device uploads the encrypted data and the digital summary to a pre-built blockchain network, which is used to verify the encrypted data based on a consensus algorithm. After the verification is passed, the encrypted data is distributedly stored, and the storage path and digital summary of the encrypted data are recorded.

[0022] In this embodiment, the blockchain network includes several blockchain nodes, each blockchain node corresponds to a data acquisition device, and each data acquisition device uploads the encrypted data and digital summary to the corresponding blockchain node on the blockchain network; after each data acquisition device uploads the encrypted data and digital summary, the encrypted data is verified at the corresponding blockchain node.

[0023] In this embodiment, the consensus algorithm is a PoW algorithm, a PoS algorithm or a PBFT algorithm; Among them, PoW (Proof of Work) algorithm: the earliest consensus algorithm, blockchain nodes need to compete for the right to record accounts by solving computational problems. The higher the difficulty, the higher the security and decentralization, but the greater the resource consumption; Among them, the PoS (Proof of Stake) algorithm: blockchain nodes obtain the right to record accounts based on the number and duration of tokens they hold, which does not require a lot of calculations and is more energy-efficient; Among them, the PBFT (Delegated Proof of Stake) algorithm is suitable for scenarios where there are a large number of nodes and they do not trust each other. It selects node representatives through voting to keep accounts, taking into account both efficiency and decentralization.

[0024] In this embodiment, there are two ways to store the encrypted data after verification: First, when the amount of encrypted data is less than the preset amount, the amount of encrypted data is relatively small, and the encrypted data can be directly stored on the blockchain network; Second: When the amount of encrypted data is greater than or equal to the preset amount of data, the amount of encrypted data at this time exceeds the storage limit of the blockchain network itself. At this time, a distributed storage system is built, such as a distributed database. The distributed database has multiple storage nodes, and multiple encrypted data blocks are stored on corresponding storage nodes, and the storage path of each encrypted data block is recorded.

[0025] As a further optimization of this embodiment, a smart contract is deployed on the blockchain network, and the smart contract is used to define data access rights and sharing rules. The sharing rules include the principle of legality, the principle of purpose limitation, the principle of transparency, the principle of quality, etc. Among them, the principle of legality is to ensure that data sharing complies with the requirements of relevant laws and regulations; the principle of purpose limitation is that the use of data should be limited to the specific purpose clearly stated at the time of sharing, and shall not be used beyond the scope; the principle of transparency is that the process of data sharing should remain transparent, and the data subject should be able to understand how its data is shared and used; the quality principle is that the shared data should be accurate, complete and timely.

[0026] The blockchain network is also used to: Step a10: obtaining a data access request from a requesting party, where the requesting party may be a user or a third party; Step a20: respond to the data access request and verify the identity and authority of the requester based on the smart contract; in this embodiment, when a user or a third party requests to access data, the smart contract will automatically verify their identity and authority to ensure the legal circulation of data; Step a30: After the verification is passed, the encrypted data and corresponding storage path and digital summary required by the requester are extracted according to the identity and authority of the requester; Step a40: Send the extracted encrypted data required by the demander, the corresponding storage path and the digital summary to the demander.

[0027] As a further optimization of this embodiment, the method further includes: Step b10: the demander performs integrity verification and consistency verification on the received encrypted data according to the received digital summary and storage path to obtain a verification result; Step b20: When the verification result is that the integrity verification fails and / or the consistency verification fails, trace the problematic blockchain node according to the records on the blockchain network and request error correction.

[0028] In this embodiment, after receiving the required encrypted data, the demander verifies the integrity and consistency of the data through the digital summary recorded on the blockchain network. If data is found to be missing or wrong, the problem node can be traced back and correction can be requested based on the on-chain records. Therefore, each data collection, transmission, storage and access is recorded on the blockchain to form a complete traceability record. Any data change operation (such as supplementation, deletion) must be subject to on-chain consensus and audit to ensure data transparency and credibility.

[0029] The present invention has the following advantages: 1. Data credibility and tamper-proof: With the distributed ledger and tamper-proof characteristics of blockchain, the authenticity and integrity of geophysical data from collection, transmission to storage are ensured, effectively avoiding risks such as data tampering and forgery, and providing a credible data foundation for multi-party collaboration; 2. Improved data transmission security: Through data encryption, digital summary and blockchain consensus mechanism, full-link data protection is achieved, avoiding the middleman attacks and data leakage problems common in traditional centralized communications, and significantly enhancing the security of data transmission; 3. Transparency and full-chain traceability: Each data operation is recorded on the blockchain, forming an unalterable traceability record, providing full life cycle management and auditability of data, and reducing the cost and complexity of data management; 4. Optimize data sharing efficiency: Automated access control and data sharing are achieved through smart contracts, which not only improves data circulation efficiency, but also ensures data ownership and privacy security, and reduces human intervention; 5. Flexible on-chain and off-chain (on-chain is blockchain node, off-chain is distributed database) combined storage: While ensuring data credibility, off-chain storage is used to reduce blockchain storage pressure, adapting to the characteristics of large amounts of geophysical data, and taking into account both performance and economy; 6. Decentralization and high reliability: It gets rid of the dependence on single-point servers, improves the system's ability to resist failures, and provides stable support for complex and distributed geophysical exploration environments.

[0030] In summary, the present invention greatly improves the efficiency and reliability of geophysical data communication, and provides important support for technological innovation in the exploration field.

[0031] Secondly, the present invention can be widely used in geophysical exploration, geological survey, environmental monitoring and other fields, providing a reliable and efficient data communication foundation for multi-party collaboration. At the same time, its innovation in data security and transparency can also be extended to other industries with high requirements for data credibility, such as medical, energy and finance.
