Description

Technical Field

[0001] This invention belongs to the field of data processing technology, and in particular relates to a method and terminal device for ensuring the integrity of data storage. Background Technology

[0002] With the development of the internet, marriage registration systems now cover the entire country, resulting in a massive amount of data due to the large population base. Currently, marriage data is generally stored in local databases or dedicated storage devices. Because this data is crucial for people's daily business transactions, frequent operations on it could lead to data loss or corruption, severely impacting people's lives and work. Therefore, the integrity of marriage data storage in marriage registration systems is paramount. However, current methods for verifying data integrity typically apply the same verification method to all data, leading to either complex verification methods or inaccurate results due to overly simplistic methods.

[0003] Therefore, there is an urgent need for a method to verify the integrity of data storage and to recover incomplete data. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a method and terminal device for processing data storage integrity, which are intended to verify the integrity of data storage and recover incomplete data.

[0005] To achieve the above objectives, a first aspect of the present invention provides a method for processing data storage integrity, comprising:

[0006] Obtain the data to be processed;

[0007] The data to be processed is stored in a local database and on a blockchain, respectively.

[0008] Upon receiving an instruction to verify the integrity of data in the database, the data to be processed in the database is verified according to its importance.

[0009] When the verification result indicates that the data to be processed is incomplete, the target data stored on the blockchain will be updated or replaced with the marriage data to be processed.

[0010] As another embodiment of this application, the data to be processed is stored in a local database and on a blockchain, respectively, including:

[0011] The data to be processed is divided into multiple data blocks;

[0012] Calculate the data length and MD5 value of the data to be processed in each data block, and associate the calculated data length and MD5 value with the data to be processed in the corresponding data block to obtain the data to be stored.

[0013] The data to be stored is stored in both the database and the blockchain, and an association table is established to determine the storage locations of the same data in the database and the blockchain.

[0014] The relationship table is stored in the database.

[0015] As another embodiment of this application, dividing the data to be processed into multiple data blocks includes:

[0016] The data to be processed is divided according to the records of different users, resulting in a data block corresponding to each record;

[0017] Alternatively, the data to be processed can be divided according to the data acquisition time to obtain multiple data blocks.

[0018] As another embodiment of this application, the step of verifying the data to be processed in the database according to the importance of the data to be processed includes:

[0019] When the importance level of the data to be processed is the first level, the data length of the data to be processed is calculated; the first level is the lowest level of importance.

[0020] The length of the calculated data is consistent with the length of the data to be processed stored in the database.

[0021] When the calculated data length matches the data length corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is complete; when the calculated data length does not match the data length corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is incomplete.

[0022] As another embodiment of this application, the step of verifying the data to be processed in the database according to the importance of the data to be processed includes:

[0023] When the importance level of the data to be processed is the second level, the data length and MD5 value of the data to be processed are calculated respectively; the second level is a level whose importance is greater than the first level.

[0024] The system detects whether the calculated data length is consistent with the data length corresponding to the data to be processed stored in the database, and whether the calculated MD5 value is consistent with the MD5 value corresponding to the data to be processed stored in the database.

[0025] When the calculated data length matches the data length corresponding to the data to be processed stored in the database, and the calculated MD5 value matches the MD5 value corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is complete; when the calculated data length does not match the data length corresponding to the data to be processed stored in the database, and / or the calculated MD5 value does not match the MD5 value corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is incomplete.

[0026] As another embodiment of this application, the step of verifying the data to be processed in the database according to the importance of the data to be processed includes:

[0027] When the importance level of the data to be processed is the third level, and the data length and MD5 value of the data to be processed are both correct, the target data corresponding to the data to be processed stored on the blockchain is obtained according to the established association table; the third level is the highest level of importance.

[0028] The data to be processed is compared one by one with the target data obtained from the blockchain. When the data to be processed is exactly the same as the target data obtained from the blockchain, the verification result is determined to be that the data to be processed is complete; when the data to be processed is not exactly the same as the target data obtained from the blockchain, the verification result is determined to be that the data to be processed is incomplete.

[0029] In another embodiment of this application, after acquiring the data to be processed, the method further includes:

[0030] The data to be processed is processed using default values.

[0032] The acquisition module is used to acquire data to be processed.

[0033] The storage module is used to store the data to be processed in a local database and on the blockchain, respectively.

[0034] The verification module is used to verify the data to be processed in the database according to the importance of the data to be processed when it receives an instruction to verify the integrity of the data in the database.

[0035] The processing module is used to update or replace the marriage data to be processed by storing the target data on the blockchain when the verification result indicates that the data to be processed is incomplete.

[0036] A third aspect of the present invention provides a terminal device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the data storage integrity processing method as described in any of the above embodiments.

[0037] A fourth aspect of the present invention provides a computer-readable storage medium, comprising: the computer-readable storage medium storing a computer program, wherein when the computer program is executed by a processor, it implements the steps of the data storage integrity processing method as described in any of the above embodiments.

[0038] The beneficial effects of this invention compared to existing technologies are as follows: Compared to existing technologies, this invention stores the data to be processed in a local database and on a blockchain respectively; upon receiving an instruction to verify the integrity of data in the database, the data to be processed in the database is verified according to its importance; when the verification result indicates that the data to be processed is incomplete, the target data stored on the blockchain is used to update or replace the data to be processed. This allows for integrity verification of data of different importance levels, and when the verification result indicates that the data is incomplete, the target data stored on the blockchain is retrieved to update or replace the data to be processed.

[0043] Figure 4 This is a schematic diagram of a terminal device provided in an embodiment of the present invention. Detailed Implementation

[0044] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0045] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0046] Figure 1 The following is a detailed flowchart illustrating a method for handling data storage integrity according to an embodiment of the present invention.

[0047] Step 101: Obtain the data to be processed.

[0048] In this embodiment, we will use marriage data from the marriage registration system as an example to describe the data to be processed.

[0049] The marriage registration system stores marital data for both men and women who are currently in a marital relationship or who have been married in the past.

[0050] Optionally, after obtaining the data to be processed in this step, the data can be preprocessed before performing the operation in step 102. Here, preprocessing refers to processing the default values ​​in the data to be processed to ensure that the data is complete.

[0051] Step 102: Store the data to be processed in a local database and on a blockchain, respectively.

[0052] Optional, such as Figure 2 As shown, this step may include the following process:

[0053] Step 201: Divide the data to be processed into multiple data blocks.

[0054] The data to be processed is divided according to the records of different users, resulting in a data block corresponding to each record;

[0055] Alternatively, the data to be processed can be divided into multiple data blocks according to the data acquisition time. For example, the data to be processed can be divided according to the marriage registration time, so that each record corresponds to a data block.

[0056] In this step, the marriage data is divided into multiple data blocks to convert large data into smaller data for processing. If the smaller data is lost or damaged during subsequent operations, it will have a smaller impact on other data, thereby improving the integrity of data storage.

[0057] Step 202: Calculate the data length and MD5 value of the data to be processed in each data block, and associate the calculated data length and MD5 value with the data to be processed in the corresponding data block to obtain the data to be stored.

[0058] Message-Digest Algorithm 5 (MD5) is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value to ensure the integrity and consistency of transmitted information.

[0059] In this step, the data length and MD5 value are associated with the marriage data in the corresponding data block and stored together. This way, when performing integrity verification on the marriage data, the data length or MD5 value corresponding to the marriage data can be directly obtained for judgment, saving verification time and improving verification efficiency.

[0060] Step 203: Save the data to be stored in the database and on the blockchain respectively, and establish an association table of the storage locations of the same data to be stored in the database and on the blockchain.

[0061] In essence, a blockchain is a shared database where the data or information stored has characteristics such as "unforgeable" and "traceable," thus ensuring the reliability of data stored on the blockchain.

[0062] After storing the data to be stored in the database and on the blockchain, it is necessary to establish a relationship table for the storage locations of the same data in the database and on the blockchain. This allows us to quickly find the location of the marriage data stored on the blockchain based on the relationship table.

[0063] Optionally, the association table can be a correspondence table between locations in the database and locations on the blockchain. The association table may also include key information such as marriage data stored in the database. In this embodiment, the data stored in the association table is not limited, but at a minimum, the correspondence between locations in the database and locations on the blockchain must be stored.

[0064] Step 204: Store the association table in the database.

[0065] Step 103: Upon receiving an instruction to verify the integrity of data in the database, the data to be processed in the database is verified according to its importance.

[0066] The frequency of data integrity verification can be set according to requirements, such as once a month, once a quarter, etc.

[0067] Optionally, the importance of the data to be processed can be classified into first level, second level, and third level, from low to high.

[0068] Optionally, in this embodiment, when verifying marriage data, the verification can be based on its importance. The higher the importance, the more complex the verification method and the higher the accuracy. When the importance level is first, only the data length of the marriage data can be verified. When the importance level is second, both the data length and MD5 value of the marriage data can be verified simultaneously. When the importance level is third, in addition to verifying both the data length and MD5 value of the marriage data, the marriage data stored in the database and the marriage data stored on the blockchain are compared one by one.

[0069] Optionally, this step may include:

[0070] When the importance level of the data to be processed is the first level, the data length of the data to be processed is calculated; the first level is the lowest level of importance.

[0071] The length of the calculated data is consistent with the length of the data to be processed stored in the database.

[0072] When the calculated data length matches the data length corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is complete; when the calculated data length does not match the data length corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is incomplete.

[0073] Optionally, this step may include:

[0074] When the importance level of the data to be processed is the second level, the data length and MD5 value of the data to be processed are calculated respectively; the second level is a level whose importance is greater than the first level.

[0075] The system detects whether the calculated data length is consistent with the data length corresponding to the data to be processed stored in the database, and whether the calculated MD5 value is consistent with the MD5 value corresponding to the data to be processed stored in the database.

[0076] When the calculated data length matches the data length corresponding to the data to be processed stored in the database, and the calculated MD5 value matches the MD5 value corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is complete; when the calculated data length does not match the data length corresponding to the data to be processed stored in the database, and / or the calculated MD5 value does not match the MD5 value corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is incomplete.

[0077] Optionally, this step may include:

[0078] When the importance level of the data to be processed is the third level, and the data length and MD5 value of the data to be processed are both correct, the target data corresponding to the data to be processed stored on the blockchain is obtained according to the established association table; the third level is the highest level of importance.

[0079] The data to be processed is compared one by one with the target data obtained from the blockchain. When the data to be processed is exactly the same as the target data obtained from the blockchain, the verification result is determined to be that the data to be processed is complete; when the data to be processed is not exactly the same as the target data obtained from the blockchain, the verification result is determined to be that the data to be processed is incomplete.

[0080] If the verification result indicates that the data to be processed is complete, it means that the data to be processed in the database has not been lost or damaged. If the verification result indicates that the data to be processed is incomplete, it means that the data to be processed in the database has been lost or damaged. In this case, data recovery needs to be performed according to step 104.

[0081] Step 104: When the verification result indicates that the data to be processed is incomplete, update or replace the data to be processed with the target data stored on the blockchain.

[0082] Here, the target data is the same as the data to be processed stored in the database. Based on the established association table, the target data corresponding to the data to be processed stored on the blockchain can be obtained.

[0083] The aforementioned method for handling data storage integrity involves storing the data to be processed in a local database and on a blockchain. Upon receiving an instruction to verify the integrity of data in the database, the data to be processed is verified according to its importance. If the verification result indicates that the data to be processed is incomplete, the target data stored on the blockchain is used to update or replace the data to be processed. This allows for integrity verification of data of varying importance, and when the verification result indicates incomplete data, the target data stored on the blockchain is retrieved to update or replace the data to be processed, thereby ensuring the integrity of the data stored in the database.

[0084] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0085] Corresponding to the data storage integrity processing method described in the above embodiments, Figure 3 An example diagram of a data storage integrity processing apparatus provided in an embodiment of the present invention is shown. Figure 3 As shown, the device may include: an acquisition module 301, a storage module 302, a verification module 303, and a processing module 304;

[0086] The acquisition module 301 is used to acquire data to be processed;

[0087] Storage module 302 is used to store the data to be processed in a local database and on a blockchain, respectively.

[0088] The verification module 303 is used to verify the data to be processed in the database according to the importance of the data to be processed after receiving an instruction to verify the integrity of the data in the database.

[0089] The processing module 304 is used to update or replace the marriage data to be processed by the target data stored on the blockchain when the verification result indicates that the data to be processed is incomplete.

[0090] Optionally, when the storage module 302 stores the data to be processed in a local database and on the blockchain respectively, it can be used for:

[0091] The data to be processed is divided into multiple data blocks;

[0092] Calculate the data length and MD5 value of the data to be processed in each data block, and associate the calculated data length and MD5 value with the data to be processed in the corresponding data block to obtain the data to be stored.

[0093] The data to be stored is stored in both the database and the blockchain, and an association table is established to determine the storage locations of the same data in the database and the blockchain.

[0094] The relationship table is stored in the database.

[0095] Optionally, when the storage module 302 divides the data to be processed into multiple data blocks, it is further used to:

[0096] The data to be processed is divided according to the records of different users, resulting in a data block corresponding to each record;

[0097] Alternatively, the data to be processed can be divided according to the data acquisition time to obtain multiple data blocks.

[0098] Optionally, when the verification module 303 verifies the data to be processed in the database according to the importance of the data to be processed, it can be used to:

[0099] When the importance level of the data to be processed is the first level, the data length of the data to be processed is calculated; the first level is the lowest level of importance.

[0100] The length of the calculated data is consistent with the length of the data to be processed stored in the database.

[0101] When the calculated data length matches the data length corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is complete; when the calculated data length does not match the data length corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is incomplete.

[0102] Optionally, when the verification module 303 verifies the data to be processed in the database according to the importance of the data to be processed, it can be used to:

[0103] When the importance level of the data to be processed is the second level, the data length and MD5 value of the data to be processed are calculated respectively; the second level is a level whose importance is greater than the first level.

[0104] The system detects whether the calculated data length is consistent with the data length corresponding to the data to be processed stored in the database, and whether the calculated MD5 value is consistent with the MD5 value corresponding to the data to be processed stored in the database.

[0105] When the calculated data length matches the data length corresponding to the data to be processed stored in the database, and the calculated MD5 value matches the MD5 value corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is complete; when the calculated data length does not match the data length corresponding to the data to be processed stored in the database, and / or the calculated MD5 value does not match the MD5 value corresponding to the data to be processed stored in the database, the verification result is determined to be that the data to be processed is incomplete.

[0106] Optionally, when the verification module 303 verifies the data to be processed in the database according to the importance of the data to be processed, it can be used to:

[0107] When the importance level of the data to be processed is the third level, and the data length and MD5 value of the data to be processed are both correct, the target data corresponding to the data to be processed stored on the blockchain is obtained according to the established association table; the third level is the highest level of importance.

[0108] The data to be processed is compared one by one with the target data obtained from the blockchain. When the data to be processed is exactly the same as the target data obtained from the blockchain, the verification result is determined to be that the data to be processed is complete; when the data to be processed is not exactly the same as the target data obtained from the blockchain, the verification result is determined to be that the data to be processed is incomplete.

[0109] The processing module 304 can also be used to: perform default value processing on the data to be processed.

[0110] The aforementioned data storage integrity processing device stores the data to be processed in a local database and on a blockchain via a storage module. Upon receiving an instruction to verify the integrity of data in the database, the verification module verifies the data in the database according to its importance. If the verification result indicates that the data to be processed is incomplete, the processing module updates or replaces the data to be processed with target data stored on the blockchain. This allows for integrity verification of data of varying importance, and when the verification result indicates incomplete data, it retrieves target data stored on the blockchain to update or replace the data to be processed, thereby ensuring the integrity of the data stored in the database.
