[0049] This application utilizes a distributed caching approach to achieve real-time data transmission and processing. At the same time, through anti-tampering methods, it can ensure that the data is not tampered with or maliciously modified during transmission and processing.
[0050] The following describes some embodiments of this application in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0051] This application provides a data tamper-proof method applied to a molecular refining model. Molecular refining is a technology that understands and optimizes petroleum processing at the molecular level. It accurately predicts product properties and optimizes processes and workflows by analyzing the molecular composition of crude oil in detail, thereby increasing the value of each molecule. Molecular refining technology follows the principle of "making the most of everything," adhering to the principles of "using oil where appropriate, aromatics where appropriate, olefins where appropriate, lubricants where appropriate, and chemicals where appropriate," to achieve the goal of "zero waste and complete utilization." Here, the molecular refining model represents the entire process or complete production line of the production process. The data in the molecular refining model includes all data from raw materials to finished products, such as material data, molecular data, equipment data, and flow data.
[0052] Material Data: All material data involved in the molecular refining model, uniformly coded; each material is composed of several molecules, corresponding to a set of molecular composition data for each material data item. At a minimum, it includes: Material ID, Material Name, Material Code, Molecular ID, and Molecular Content. See the table below:
[0053] Material ID Material Name Material coding Molecular ID Molecular content
[0054] Molecular data: Structure-guided lumped molecular characterization (SOL) was employed, where each molecule is composed of distinct structural units. This includes at least: molecule ID and a vector representing the composition of molecular structural units. See the table below:
[0055]
[0056] Equipment data: All equipment and reaction condition parameters involved in the molecular refining model are uniformly coded; at a minimum, they include: equipment ID, equipment code, equipment name, reaction pressure, reaction temperature, flow rate, and volume. See the table below:
[0057] ID coding Device Name Reaction pressure reaction temperature Flow rate volume
[0058] Flow data: Describes the flow relationship between equipment and materials, including material code, equipment code, and flow type, where -1 indicates inflow and 1 indicates output. It must include at least: Model ID, Equipment ID, Material ID, and Flow Type. See the table below:
[0059] Model ID Device ID Material ID Circulation type
[0060] After obtaining the above data, this application embodiment needs to use the above data to build a distributed caching system.
[0061] To ensure data security when constructing a distributed caching system, this embodiment does not directly construct a data digest from the collected material data, molecular data, device data, and circulation data. Instead, it first processes the material data, molecular data, device data, and circulation data using a preset digest algorithm to obtain data digests for each type of data. The digest algorithm can be a hash algorithm, a hash function, etc. Preferably, this embodiment uses a hash algorithm. The SHA-256 hash algorithm is used to calculate the first data digest for the material data, the second data digest for the molecular data, the third data digest for the device data, and the fourth data digest for the circulation data. Here, the data digest represents a fixed-length string generated from the original data.
[0062] Furthermore, after obtaining the data digest, this embodiment of the application encrypts the data digest to obtain encrypted data. The encryption method used here is symmetric encryption, such as using the RSA algorithm to encrypt the data digest. Specifically, the RSA algorithm is used to process the first, second, third, and fourth data digests respectively, resulting in first, second, third, and fourth encrypted data. After obtaining the encrypted data, a distributed caching system is constructed using the encrypted data. That is, the first, second, third, and fourth encrypted data are stored in preset distributed caching nodes to obtain the distributed caching system. When storing the encrypted data, to ensure the normal operation of business processes, this embodiment of the application also needs to store metadata. This metadata mainly includes the storage location of each encrypted data item in the distributed caching system, the encryption key identifier, and the digital signature.
[0063] After the distributed caching system is built, it is also necessary to configure interceptors for it. Interceptors primarily handle tasks such as parsing request parameters, assigning page form parameters to corresponding attributes in the value stack, performing functional checks, and debugging program exceptions. During configuration, the model identifier and user identifier are written into different cache lock tables according to the type of the molecular refining model, and lock / unlock messages are sent via a message queue. Before any business operation, the system verifies whether a locked model identifier exists in the cache; if so, the operation is prohibited and a prompt message is returned.
[0064] In practice, the SQL statements for adding, deleting, and modifying data are intercepted, and the model_id is obtained by parsing the SQL. The user_id is then obtained by accessing the logged-in user information.
[0065] Locking: For a single-factory model, the model_id and user_id will be inserted into the info_model_lock table, and the model_ids will be stored in the cache as a set of modelids for later use. At the same time, a lock message will be sent to the Redis message queue. If model A is multi-factory, the model_id and user_id will be inserted into the z_info_model_exeresult table, and the model_ids will be stored in the cache as a set of zmodel_ids for later use. At the same time, a lock message will be sent to the Redis message queue.
[0066] Business operations: When performing add, delete, or modify operations on model A, the business code is executed first. After the business code executes, it is intercepted by interceptor B. The interceptor can parse the model_id and user_id from the SQL. At this point, it retrieves the modelset from the cache and checks if the modelid exists in this set. If it exists, it modifies the message to: "Model A is locked and cannot be modified." This solves the problem of model data being tampered with after locking.
[0067] Unlock: Retrieve `model_id` and `user_id`. If model A is a single-factory model, clear the `model_id` data from the `modelids` cache, delete the corresponding data from the `info_model_exeresult` table in the database, and simultaneously publish a single-factory unlock message to the Redis message queue. If model A is a dual-factory model, clear the `model_id` data from the `zmodel_ids` cache, delete the corresponding data from the `z_info_model_exeresult` table in the database, and simultaneously publish a dual-factory unlock message to the Redis message queue.
[0068] In addition to model_id and user_id, interceptor design can also include device ID and material ID to control the interception scope. Specific user settings need to be determined based on the role-based access control design to determine whether the user has CRUD (Create, Read, Update, Delete) permissions.
[0069] After the interceptor is set up, when a user's data operation request is received, the data operation request is verified based on the interceptor. If the verification is successful, the target data from the distributed cache node is operated on.
[0070] Data operation requests here include data query requests and data update requests. If the data operation request is a data query request, the data query request is verified based on the data signature. If the verification passes, the user is allowed to query the data. Specifically, the received query request is decrypted, and the decrypted digital signature is verified to be consistent with the digital signature in the cache node. If the digital signature of the decrypted data does not match the digital signature in the cache node, the query request is rejected, and the data is considered to have been tampered with; otherwise, the data is returned according to the query request.
[0071] If the data operation request is a data update request, the data operation request is verified based on the data signature. If the verification passes, the data operation request is further verified based on the interceptor. If the verification passes, the target data from the distributed cache node is operated on. First, the data to be updated is queried. For the queried data, the interceptor status is checked. If the interceptor status is closed, a timestamp is recorded, and the corresponding cache node can be updated; otherwise, access to modification is denied.
[0072] In an optional implementation, to ensure the traceability of data modifications, embodiments of this application record the operation information corresponding to the data operation request and store it in the blockchain. This operation information includes timestamps, user characteristic information, interceptor status, and operation type, etc.
[0073] In an optional implementation, it can be carried out in accordance with... Figure 2 The steps shown are performed, for example, a process engineer at an oil refinery needs to update the reaction temperature parameters of unit A to optimize the operating efficiency of a molecular refining model. The following is the coordinated execution process of each step in this operation:
[0074] The raw data of device A (device ID: A001, current reaction temperature: 300℃) is stored in distributed cache nodes (node 1) according to business segments. At the same time, the material data (such as material ID: M001, including a list of molecular IDs) and molecular data (such as molecular ID: Mol001, structure vector) associated with device A are redundantly backed up on nodes 2 and 3.
[0075] The SHA-256 algorithm is used to generate a digest of the data from device A (e.g., digest value: a1b2c3...), and the original data is encrypted using an RSA public key.
[0076] Metadata records: Storage location (node 1), encryption key identifier (KeyID:RSA_123), digest value and digital signature are written to the metadata database.
[0077] Query Request: The engineer initiates a query request for device A data through the client and needs to submit a CA-certified digital certificate (certificate ID: Cert_XYZ).
[0078] Decryption and Verification: Node 1 decrypts the data using the RSA private key, recalculates the digest, and compares it with a1b2c3... in the metadata. If the deviation is within the threshold, the verification is successful.
[0079] Alarm mechanism: If the summary deviation exceeds the threshold (e.g., data has been tampered with), the node will trigger an alarm and block the query.
[0080] Update operation triggered: The engineer submits an SQL update statement (UPDATE Device Table SET Temperature = 320 WHERE Device ID = A001).
[0081] Interceptor parsing: The interceptor extracts the model ID (Model_A), user ID (User_123), and device ID (A001).
[0082] Locking process:
[0083] Model type determination: Model_A is a single-factory model. Write Model_A and User_123 into the info_model_lock table.
[0084] Cache locking: Model_A is added to the cache collection modelids, and a locking message is sent via Redis.
[0085] Permission verification: When other users attempt to modify Model_A, the interceptor detects a locked record in modelids and returns the message "Model is locked and cannot be modified".
[0086] All operations (query, lock, update) are written to the blockchain. For example:
[0087] {
[0088] Operation time: "2023-10-05 14:30:00";
[0089] Operation type: "Update";
[0090] "User ID":"User_123";
[0091] "Model ID":"Model_A";
[0092] Node IP: "192.168.1.100";
[0093] "Digital Signature":"signature_abc..."
[0094] }
[0095] Multidimensional search: Administrators can quickly locate logs by time range (e.g., "2023-10-05") and operation type ("update").
