[0053] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0054] It should be noted that the concepts such as "first" and "second" mentioned in the present application are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence relationship of the functions performed by these devices, modules or units. The terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the element.

[0055] The embodiments of the present application provide a method for preventing tampering of supervision data, as Figure 1 shown, specifically including the following steps:

[0056] S101. For each supervision form within the supervision scope, determine whether there are new records in the supervision form.

[0057] It should be noted that the supervised entity submits supervision data in the system within the first preset time range (for example, 8:00 to 19:00) during the day of T; the data submission channel is closed during other time periods, and the anti-tampering system obtains the supervision data within the first preset time range within the second preset time range (for example, 0:00 to 1:00) of T + 1.

[0058] It is understandable that the first preset time range and the second preset time range can be set and changed by technical personnel or relevant authorized staff, and are not limited here.

[0059] Specifically, the number of monitoring data items in each monitoring table within the monitoring range of the anti-tampering system is updated one by one. The number of data items currently recorded in the monitoring table R t The number of data items recorded on the previous day R t-1 If the two are the same, it means that there is no new record. Otherwise, there is a new record. If it is determined that there is a new record in the supervision table, step S102 is executed.

[0060] In the specific implementation of this application, each supervision table within the supervision scope belongs to the supervised library table range table, which is a parameter table, as shown in Table 1, which defines the key information of the full supervision data table. Considering that the length of a single record in each data table is inconsistent, the step data item is designed and can support dynamic settings.

[0061] Library Number Library Number Name Table Name Step Size Number of Records of the Previous Day Current Number of Records Timestamp

[0062] Table 1

[0063] It should be noted that after the database table is divided by region, the summary information of each region is saved in the regulated data summary table, as shown in Table 2.

[0064] Data Item Name Definition Serial Number Library Name Name of the Library Where the Supervised Data Is Located Table Name Name of the Table Where the Supervised Data Is Located Starting Serial Number Starting Position of the Summary Calculation Area in the Data Table Summary Summary of the Corresponding Area in the Data Table Creation Date Revision Date There is a modification operation in the stock data area, indicating the last modification time of the summary information Consistency Record whether the last data verification matches, value: 0 no, 1 yes Timestamp

[0065] Table 2

[0066] S102: Determine the number of areas to be updated in the supervision table according to the number of data items recorded on day T, the number of data items recorded on day T-1, and the step length in the supervision table.

[0067] Specifically, the number of areas to be updated can be calculated using the following formula:

[0068] in, The symbol is rounded up, and P represents the step size.

[0069] S103. Determine whether there is stock data in the T-day region header of the supervision table based on the number of data items and the step length recorded on day T-1.

[0070] Continuing with the above example, if R t-1 / P is an integer, indicating that there is no inventory data in the regional header on day T; otherwise, it means that there is inventory data in the regional header on day T.

[0071] S104. If there is stock data in the T-day regional header of the supervision form, determine whether the stock data in the T-day regional header has been tampered with based on the summary of the (T-1)-day regional header.

[0072] The judgment method can be as follows:

[0073] Obtain and calculate the starting data of the (T-1) day The hash value h of the data table area (regional header) where the t-1 ... If it is the same as the hash value of this area in the supervised data summary table on the (T-1) day, it means that the t-1 stock data in the area where R is located has not been tampered with on the T day, otherwise it has been tampered with. Among them, represents rounding down.

[0074] Specifically, if it is determined that the stock data in the T-day regional header has not been tampered with, execute step S105; if it is determined that the stock data in the T-day regional header has been tampered with, execute step S108.

[0075] S105. Update the summary of the T-day regional header.

[0076] Specifically, recalculate the hash value of the regional header on the T day and save it to the summary table.

[0077] S106. Determine whether the number of areas to be updated is 1.

[0078] Specifically, if the number of areas to be updated is not 1, execute step S107; if the number of areas to be updated is 1, execute step S108.

[0079] S107. Determine the summary of the part except the regional header on the T day.

[0080] Specifically, calculate the hash value of the area where its data is located and save it; where i = 1, 2, 3... n t-1 Repeat n t-1 times.

[0081] Assume that the regional record step size is p, the starting number of records is R n and R n+p , and the calculation steps of the hash value of a single area are as follows:

[0082] ① Arrange the regional records in order according to the serial number from R n records, and convert all fields into strings S n ... S n+p ...

[0083] ② After splicing all the strings, obtain the single-area string S.

[0084] ③ Calculate the hash value h(S) based on the information digest MD5 algorithm to obtain the hash value of this area. The hash value result is represented in base 64 and has a length of 22 characters.

[0085] S108. Change the consistency record information in the supervision data summary to inconsistent.

[0086] Optionally, in another embodiment of the present application, if in step S103, it is determined that there is no stock data in the T-day area header of the supervision table, directly execute step S105 and subsequent steps.

[0087] Optionally, in another embodiment of the present application, an implementation manner of the anti-tampering method for supervision data is as Figure 2 shown, and further includes:

[0088] S201. Receive the maintenance request for the monitoring data of the supervised entity.

[0089] S202. Send request reply information to the supervised entity.

[0090] Among them, the request reply information is whether to agree to the supervised entity to maintain the monitoring data.

[0091] Specifically, during the day, if the supervised entity finds that the reported supervision data is incorrect, it can apply in the anti-tampering system to the supervision entity. After the supervision entity approves the application in the anti-tampering system, the supervised entity maintains the correct data in the anti-tampering system. The anti-tampering system updates the digital signature within the third preset time period (for example, from 23:00 to 24:00 at the end of the day). The specific operations are as follows:

[0092] ① The supervision entity queries the reported data in the anti-tampering system and selects the incorrect data record for application for maintenance. The application transaction is saved in the "Supervision Data Operation Transaction" table.

[0093] ② The supervised entity reviews the data maintenance application. If the review is passed, modify the operation status in the "Supervision Data Operation Transaction" table to "review passed".

[0094] ③ The supervised entity completes the data maintenance in the anti-tampering system, and the background updates the operation status in the "Supervision Data Operation Transaction" table to "operation completed".

[0095] ④ Calculate the corresponding summary value of the data in the supervised data summary table according to the database name, table name, and primary key information.

[0096] In the specific implementation process of the present application, the operation can be carried out through the supervision data operation transaction table shown in Table 3:

[0097]

[0098]

[0099] Table 3

[0100] Optionally, in another embodiment of the present application, an implementation manner of the anti-tampering method for supervision data is as follows Figure 3 shown, further including:

[0101] S301. At a preset time, close the supervision data submission channel, obtain the supervision data in the supervision table, and calculate the data digest by region.

[0102] S302. Determine whether the data digest is consistent with the data in the digest table.

[0103] Specifically, if it is determined that the data digest is consistent with the data in the digest table, then step S303 is executed; if it is determined that the data digest is inconsistent with the data in the digest table, then step S304 is executed.

[0104] S303. Determine that there is no tampering behavior in the supervision data.

[0105] S304. Determine that there is a tampering behavior in the supervision data, and update the status of the corresponding record in the digest table to inconsistent.

[0106] Specifically, close the supervision data submission channel at a specific time, obtain the supervision data in the data table, calculate the data digest by region, and check it with the digest table. If they are consistent, the data is correct; if they are inconsistent, it means that there is a tampering behavior in the supervision data. If they are inconsistent, update the status of the corresponding record in the digest table to "inconsistent".

[0107] It can be seen that in the anti-tampering method provided in the application, the size and data structure of the data table are not restricted. The supervision data table of any size can be regionally segmented by step length, and the MD5 algorithm is applied to each region to generate a short string of fixed length. Finally, a large number of data in the data table are mapped into a digest sequence with a controllable length, achieving the purpose of automatically checking a large amount of data with small data. Moreover, it effectively supervises the behavior of privately tampering with supervision data and protects the security of supervision data. Furthermore, the anti-tampering system includes the business scenarios of legally maintaining data, ensuring the reasonable data maintenance requirements of the supervised units, realizing all-online operations for data processing, and standardizing the process. In particular, it can greatly improve the supervision unit's control over data security and data quality in the hosting mode.

[0108] As can be seen from the above solution, the present application provides a method for preventing the tampering of supervision data: First, for each supervision table within the supervision scope, it is determined whether there are new records in the supervision table; if it is determined that there are new records in the supervision table, the number of data records on day T, the number of data records on day T-1, and the step size in the supervision table are used to determine the number of areas to be updated in the supervision table; according to the number of data records on day T-1 and the step size, it is determined whether there is stored data at the header of the T-day area in the supervision table; if there is stored data at the header of the T-day area in the supervision table, it is determined whether the stored data at the header of the T-day area has been tampered with according to the summary of the header of the T-1-day area; if it is determined that the stored data at the header of the T-day area has not been tampered with, the summary of the header of the T-day area is updated; if the number of areas to be updated is not 1, the summary of the part of the T-day area except the header is determined; if the number of areas to be updated is 1, the consistency record information in the supervision data summary is changed to inconsistent; if it is determined that the stored data at the header of the T-day area has been tampered with, the consistency record information in the supervision data summary is changed to inconsistent, and the summary of the part of the T-day area except the header is determined. Thus, it is possible to prevent the monitoring data reported by the supervision system from being tampered with by the front and back ends, and further achieve the purpose of ensuring the security and controllability of the supervision data.

[0109] Another embodiment of the present application provides a device for preventing the tampering of supervision data, as Figure 4 shown, specifically including:

[0110] The first judgment unit 401 is used to judge whether there are new records in each supervision table within the supervision scope.

[0111] The first determination unit 402 is used to, if the first judgment unit 401 determines that there are new records in the supervision table, determine the number of areas to be updated in the supervision table according to the number of data records on day T, the number of data records on day T-1, and the step size in the supervision table.

[0112] The second determination unit 403 is used to determine whether there is stored data at the header of the T-day area in the supervision table according to the number of data records on day T-1 and the step size.

[0113] The second judgment unit 404 is used to, if there is stored data at the header of the T-day area in the supervision table, judge whether the stored data at the header of the T-day area has been tampered with according to the summary of the header of the T-1-day area.

[0114] The update unit 405 is used to, if the second judgment unit 404 determines that the stored data at the header of the T-day area has not been tampered with, update the summary of the header of the T-day area.

[0115] The third determination unit 406 is used to determine the summary of the part of the T-day area except the header if the number of areas to be updated is not 1.

[0116] Change unit 407 is used to change the consistency record information in the supervision data summary to inconsistent if the number of areas to be updated is 1.

[0117] Change unit 407 is also used to change the consistency record information in the supervision data summary to inconsistent if the second judgment unit 404 determines that the inventory data of the T-day area header has been tampered with, and use the third determination unit 406 to determine the summary of the part other than the area header on T day.

[0129] A fourth determination unit is used to determine that there is no tampering behavior of the supervision data if the third judgment unit determines that the data summary is consistent with the data in the summary table.

[0130] The fourth determination unit is further configured to, if the third judgment unit determines that the data digest is inconsistent with the data in the digest table, determine that there is a tampering behavior in the supervision data, and update the status of the corresponding record in the digest table to inconsistent.

[0131] For the specific working process of the unit disclosed in the above embodiments of the present application, reference may be made to the corresponding method embodiment content, as Figure 3 shown, which will not be elaborated here.

[0132] As can be seen from the above solution, the present application provides an anti-tampering device for supervision data: First, for each supervision table within the supervision scope, the first judgment unit 401 judges whether there is a new record in the supervision table; if the first judgment unit 401 judges that there is a new record in the supervision table, the first determination unit 402 determines the number of areas to be updated in the supervision table according to the number of data records on day T, the number of data records on day T-1, and the step size in the supervision table; the second determination unit 403 determines whether there is stock data at the head of the T-day area in the supervision table according to the number of data records on day T-1 and the step size; if there is stock data at the head of the T-day area in the supervision table, the second judgment unit 404 judges whether the stock data at the head of the T-day area has been tampered with according to the digest of the head of the T-1-day area; if the second judgment unit 404 judges that the stock data at the head of the T-day area has not been tampered with, the update unit 405 updates the digest of the head of the T-day area; if the number of areas to be updated is not 1, the third determination unit 406 determines the digest of the part of the T-day area except the head of the area; if the number of areas to be updated is 1, the change unit 407 changes the consistency record information in the supervision data digest to inconsistent; if the second judgment unit 404 judges that the stock data at the head of the T-day area has been tampered with, the change unit 407 changes the consistency record information in the supervision data digest to inconsistent, and determines the digest of the part of the T-day area except the head of the area by using the third determination unit 406.
