Description

Technical Field

[0001] This disclosure relates to the field of aviation fuel information transmission technology, specifically to a method, system, device, and storage medium for sustainable aviation fuel information transmission. Background Technology

[0002] Sustainable Aviation Fuel (SAF) refers to aviation fuel made from renewable resources or waste materials that simultaneously meets airworthiness certification and sustainability requirements. SAF is compatible with existing aircraft and civil aviation infrastructure, and its life-cycle carbon emissions are reduced by more than 10% compared to fossil-based jet fuel. Only aviation fuel that has passed sustainability certification can be considered SAF and used for carbon market compliance. During the transmission of aviation fuel sustainability certification information, the entire process, including raw material traceability, production and processing, and trading, faces serious risks of tampering or falsification of data. Traditional recording and verification methods lack a technical means to transform certification data into a unique, immutable, cross-platform data representation and to store this representation on an immutable medium. This makes it difficult to effectively prove that the data has not been tampered with since its generation, thus failing to guarantee the authenticity and integrity of the certification information.

[0003] In summary, existing aviation fuel sustainability certification systems suffer from insufficient control over the credibility of information transmission data. They rely on offline manual operations and lack a fully online verification mechanism, making them susceptible to data tampering and forgery in data submission, review records, and certificate archiving. Furthermore, they struggle to achieve end-to-end data traceability and verification. Currently, no effective solutions have been proposed to address these issues. Generating unique, tamper-proof data fingerprints for all fields of aviation fuel data throughout the entire process, and leveraging the immutability of blockchain to construct a method that effectively prevents data tampering and forgery, achieves reliable evidence storage, and enables efficient verification, is a pressing problem that needs to be solved.

[0015] This disclosure offers the following advantages: By performing deterministic recursive sorting of all fields of data throughout the entire process using JSON key-value pairs, it enables authentication data with identical content to generate standardized strings with completely consistent order and infinite reproducibility, thereby extracting a unique data fingerprint. This fingerprint, combined with the immutability of blockchain, establishes an unalterable and trustworthy benchmark for aviation fuel authentication data. Any tampering or falsification of data content will result in a mismatch between the recalculated hash value and the on-chain notarized hash value, allowing for rapid and accurate detection and effectively curbing data tampering and falsification.

[0024] Figure 1 This is a flowchart of an exemplary embodiment of a method for transmitting sustainable aviation fuel information, such as... Figure 1 As shown, an exemplary embodiment of this disclosure provides a method for transmitting aviation fuel sustainability information, including: S1 collects the entire process business data for aviation fuel sustainability certification and converts the entire process business data into a raw JSON object; S2 performs deterministic normalization on the original JSON object to generate a normalized JSON string; the deterministic normalization includes sorting the JSON key-value pairs according to a preset sorting rule, and recursively sorting the nested JSON sub-objects and / or arrays.

S7 retrieves the data fingerprint stored in the blockchain based on the index information extracted from the business data to be verified; S8 compares the fingerprint of the data to be verified with the corresponding fingerprint stored on the blockchain, and determines the authenticity of the business data to be verified based on the comparison result.

[0025] This embodiment provides a blockchain-based method for sustainable information transmission in aviation fuel. By performing deterministic normalization (JSON key-value sorting) and hash extraction on all fields of data throughout the entire process, a unique data fingerprint is generated. This fingerprint is then stored on the blockchain, leveraging the immutability of the blockchain, achieving tamper-proof and forgery-proof trusted storage and efficient verification. Specific steps include: Data Acquisition and Formatting: Collect all business data across all fields involved in the sustainable certification of aviation fuel, and convert all fields into standard JSON objects; Deterministic normalization processing: Extract all keys from the JSON object and reorder all key-value pairs according to lexicographical order or a preset sorting rule; if there are nested JSON sub-objects or arrays, a recursive deep sorting method is used to generate a normalized JSON string with a uniquely determined key-value order, ensuring that authentication data with the same content can reproduce completely consistent serialization results in any system environment; Data fingerprint extraction: The normalized JSON string is used as input, and a standard hash algorithm is used to generate a unique data fingerprint for the authentication data; Blockchain on-chain evidence storage: The unique data fingerprint, along with the basic index information, is recorded in the blockchain ledger to obtain an evidence storage receipt containing the block height and transaction hash; Data verification and traceability: In the certification, settlement or auditing stages, the processing of S1 to S3 is replayed on the target certified data to generate a hash value to be verified and compare it with the evidence storage hash value obtained on the blockchain; if they match, it is determined that the certified data has not been tampered with since its generation, thus completing the tamper-proof transmission and verification of aviation fuel sustainability information.

[0026] This embodiment provides a blockchain-based method for transmitting sustainable aviation fuel information. By performing deterministic normalization processing (JSON key-value sorting) and hash extraction on all fields of data throughout the entire process, and combining the immutability of blockchain, it achieves reliable storage and efficient verification of sustainable aviation fuel certification data and content.

[0027] The overall implementation process is as follows: Figure 2 As shown, the system addresses the issues of inconsistent data fingerprints across systems and insufficient credibility of authentication data through five stages: data collection and formatting, deterministic sorting, hash calculation, on-chain notarization, and verification and tracing. Implementation details are as follows: Specifically, the full-process business data includes: economic operator entity information, fuel batch number, sustainable certification certificate information, full life cycle carbon emission accounting data, raw material traceability information, production process parameters, quality inspection certificates, and logistics handover records.

[0028] Specifically, S2 performs deterministic normalization on the original JSON object to generate a normalized JSON string, including: Extract all key names from the JSON object at the current level; The key names are sorted according to lexicographical order or a preset field priority rule to form a sorted sequence of key-value pairs; Iterate through each value in the sequence of key-value pairs: If each value in the key-value pair sequence is a JSON sub-object, then the key name extraction and sorting steps are executed recursively. If the value is an array and the array elements are JSON objects, then the key extraction and sorting steps are recursively performed on each JSON object in the array; if the value is a primitive data type, then it remains unchanged. The sorted and recursively processed JSON structure is serialized into a compact string without spaces, resulting in the normalized JSON string.

[0029] In this embodiment, data acquisition and structured formatting are performed as follows: This step is the data input preprocessing stage. Its purpose is to uniformly map the business data of aviation fuel sustainability certification from multiple sources throughout the entire process into a standard JSON structured object, providing a uniformly formatted input for subsequent deterministic sorting and ensuring that no field is omitted.

[0030] The system's data acquisition module collects all fields from the entire aviation fuel sustainable certification process, covering economic operator information, fuel batch numbers, sustainable certification certificate information, full lifecycle carbon emission accounting data, raw material traceability information, production process parameters, quality inspection certificates, logistics handover records, and other business fields. The system converts the collected fields into key-value pair mappings and converts them into standard JSON objects. Key names follow a unified English field naming convention, and values ​​retain their original business data types (strings, numbers, booleans, nested objects, arrays). No field deletions, content modifications, or format conversions are performed, ensuring complete mapping of all fields.

[0031] The raw JSON object output in this step is the sole data source for all subsequent processing steps, and its data integrity directly determines the accuracy of the final data fingerprint.

[0032] In this embodiment, the JSON data is ordered deterministically: This step is the core and key aspect that distinguishes this embodiment from existing technologies, solving the problems of random JSON serialization order and non-unique data fingerprints across different business systems and programming languages. Its principle is to rearrange all JSON key-value pairs using a unified sorting rule and recursively traverse and sort nested structures, completely eliminating the randomness of serialization and ensuring that the same business content outputs a unique serialized string.

[0033] Extract all keys from the current level of the JSON object, loading the lexicographical order sorting by default; if a field priority sorting table is preset in the business scenario, the preset rule is loaded. Sort all keys in the current level according to the loaded rule, and adjust the position of key-value pairs synchronously with the keys. Sorting only adjusts the order and does not modify the content or data type of any keys or values. Iterate through the sorted key-value pairs and determine the type of each value: If the value is a JSON sub-object, then the complete process of "key extraction → sorting → nested judgment" is recursively executed on the sub-object. If the value is an array: when the array elements are JSON objects, the sorting is performed recursively on each object in the array; when the array elements are strings, numbers, or other basic types, the original order of the array elements is maintained to avoid disrupting the business logic. If the value is a basic type (string, number, boolean, null), then no action is taken.

[0034] Normalized serialization output: After the full-level recursive sorting is completed, the JSON is serialized in a compact format without spaces, without adding any indentation, newline or space characters, and outputting a unique normalized JSON string.

[0035] This step takes the original JSON object and outputs a normalized string, which serves as the sole basis for subsequent hash calculations. The recursion depth corresponds one-to-one with the JSON nesting level, ensuring that all fields and all levels cover the unified sorting rules.

[0036] Specifically, the preset hash algorithm is MD5, SHA-256, or SM3.

[0037] In this embodiment, the data fingerprint hash calculation is as follows: Structure and Principle: This step is based on the one-wayness and determinism of hash algorithms, converting a normalized JSON string of arbitrary length into a unique hash value of fixed length, which serves as a unique digital fingerprint for the authentication data. This not only compresses the amount of evidence data but also ensures that data tampering can be identified.

[0038] The normalized JSON string output is used as the input parameter for the MD5 hash algorithm; the MD5 hash function is called to perform the calculation and output the hash value, which serves as the unique data fingerprint of this aviation fuel sustainability certification data.

[0039] The input for this step is a sorted, normalized string, and the output hash value is the core content of blockchain notarization. The uniformity of hash algorithm and encoding format is a necessary prerequisite for consistent hash calculation results across entities.

[0040] Specifically, the index information used to identify the data fingerprint and the index information extracted from the business data to be verified both include: fuel batch number, certification certificate number, upload subject identifier, and evidence storage timestamp.

[0041] Specifically, after S4 uploads the data fingerprint and the index information used to identify the data fingerprint to the blockchain for notarization, it includes: A receipt for obtaining data fingerprints and corresponding index information is obtained, the receipt including block height, transaction hash and on-chain timestamp; Based on the block height or transaction hash in the evidence receipt returned by the blockchain, query and display the corresponding evidence subject, evidence time, and historical status information.

[0042] In this embodiment, on-chain evidence storage is performed on the blockchain: This step leverages the immutable and traceable characteristics of blockchain's distributed ledger to solidify and preserve data fingerprints. Through the consortium blockchain's multi-node consensus mechanism, once the evidence is uploaded to the chain, it cannot be unilaterally altered and can be permanently traced through transaction hashes, thus ensuring the credibility of the authentication information from the ground up.

[0043] The generated hash value is used as the core evidence storage content, and combined with basic index information to assemble an on-chain transaction. The basic index information includes the fuel batch number, authentication certificate number, uploading entity ID, and evidence storage timestamp, used for rapid subsequent location of the evidence storage record. Authorized business entities broadcast the evidence storage transaction to the consortium blockchain network via blockchain nodes. After consensus confirmation, the transaction is packaged and written into a block. Once the transaction is on-chain, the blockchain node returns an evidence storage receipt, containing the block height, transaction hash, on-chain timestamp, and evidence storage hash value. The business system associates and stores the receipt with the original authentication data as proof for subsequent verification.

[0044] This step establishes a trusted data fingerprint, which forms the basis of trust for subsequent cross-entity verification.

[0045] Specifically, the fingerprint of the data to be verified is compared with the corresponding data fingerprint stored on the blockchain, and the authenticity of the business data to be verified is determined based on the comparison result, including: If the fingerprint of the data to be verified matches the corresponding fingerprint stored on the blockchain, it is determined that the business data to be verified has not been tampered with since it was stored; if they do not match, it is determined that the data is abnormal.

[0046] In this embodiment, data verification and traceability are as follows: This step achieves trusted verification through the logic of "replay calculation + on-chain comparison". It utilizes the sensitivity of hash algorithms (small changes in data content can lead to completely different hash values) to verify whether the authentication data has been tampered with by comparing the locally recalculated hash with the on-chain evidence storage hash.

[0047] In verification scenarios such as settlement, auditing, and cross-entity information transfer, the following process should be followed: Obtain the original sustainable certification data to be verified, along with the corresponding notarization transaction hash or batch index information; replay the complete process from S1 to S3, sequentially performing JSON formatting, recursive deterministic sorting, and MD5 hash calculation on the data to be verified to generate a local hash value to be verified; query the notarization hash value stored on the blockchain based on the transaction hash or index information through the blockchain node; if the local hash value is completely consistent with the notarization hash value on the blockchain, it is determined that the certification data has not been tampered with since the notarization date, and the data is authentic and valid; if they are inconsistent, it is determined that the data has been tampered with or that there are differences in the content. If it is necessary to trace the notarization history, the on-chain transaction details can be queried through the block height and transaction hash to obtain full-link information such as the notarization subject and notarization time, thus completing data traceability.

[0048] This step is the value output stage of this embodiment, realizing efficient and reliable verification of sustainable information, and completing the verification without transmitting the full amount of original sensitive data.

[0049] This embodiment provides a blockchain-based method for the storage and verification of sustainability information and data in the field of aviation fuel. It covers a complete technical process combination of "data collection and formatting → JSON deterministic sorting → hash fingerprint generation → blockchain on-chain storage → replay-based verification and comparison," clearly defining the combination of the specific application scenario of aviation fuel sustainability information and the entire set of technical steps. "JSON full-field deterministic recursive sorting" is included as a pre-processing step for aviation fuel sustainability information storage within the core protection scope. Specifically, it includes: sorting all key-value pairs according to lexicographical order / preset rules, recursive depth sorting of nested structures, and achieving the technical effect of unique serialization results across different technology environments. This feature is the core innovation that distinguishes this solution from general blockchain storage and is a core limiting element of the claims. The protection of the trusted verification mechanism of "on-chain storage based on normalized sorted hash + full-step replay comparison" defines the protection boundary of this verification architecture in the aviation fuel sustainability information storage scenario. This means that the technical logic of eliminating data serialization ambiguity through deterministic sorting before generating hashes on the chain and completely reproducing the preprocessing process for comparison during verification delineates the protection boundary of this verification architecture in the aviation fuel sustainability information storage scenario.
