[0015] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0016] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0017] The following, in conjunction with the accompanying drawings, describes in detail a data processing method, device, electronic device, and storage medium provided by the embodiments of the present application through specific embodiments and their application scenarios.

[0018] Figure 1 An embodiment of the present application provides a data processing method, which can be performed by an electronic device. The electronic device may include: a server and / or a terminal device. In other words, the method can be performed by software or hardware installed in the electronic device, and the method includes the following steps:

[0019] S102: In response to a first write operation on a target data block in a target file, determine a first data value corresponding to the target data block.

[0020] Wherein, the first data value is at least one write value of the target data block before receiving the first write operation. This step responds to a write operation on a data block in the target file, and determines at least one write value of the data block before this write operation. For example, each time a data block is written, a spliced ​​file can be generated for the data block, and the spliced ​​file stores the data value of the corresponding data block before this write operation. When the same data block is written again subsequently, a new spliced ​​file can be generated. In addition, a write operation log file of all data blocks in the corresponding target file can be generated for each write operation. The log file can store whether the corresponding data block has changed during a corresponding write operation or the data value of the corresponding data block before each write operation.

[0021] S104: When the first log file meets a predetermined condition, write one of the first data values ​​into a target address corresponding to the target data block.

[0022] The predetermined conditions include:

[0023] The total number of first records is greater than or equal to a first predetermined number of records, wherein the first record is used to record, in the first log file, at least one write operation corresponding to the target data block before the first write operation;

[0024] The total number of second records within the predetermined time is greater than or equal to a second predetermined number of records, wherein the second records are used to record multiple write operations corresponding to multiple data blocks in the first log file.

[0025] The first record is used to record at least one write operation corresponding to the target data block in the first log file, and the total number of first records is used to count the number of write operations corresponding to the target data block before the current write operation. When the number exceeds a first predetermined value, the at least one write value corresponding to the target data block before the current write operation is written back to the target address corresponding to the target data block.

[0026] The second record is used to record multiple write operations corresponding to multiple data blocks in the target file in the first log file, and the total number of second records within the predetermined time is used to count the number of multiple write operations corresponding to the multiple data blocks of the target file within the predetermined time. When the number exceeds a second predetermined value, at least one write value corresponding to the target data block before the current write operation is written back to the target address corresponding to the target data block.

[0027] This step counts the number of write operations on the target file data block level, and when the number of write operations on a single data block exceeds the limit or the number of write operations on the target file exceeds the limit within a predetermined time, selects the historical write value to write back to the corresponding data block, thereby achieving convenient data access and preventing data from being maliciously tampered with, thereby ensuring data security.

[0028] An embodiment of the present application provides a data processing method, which determines a first data value corresponding to a target data block in a target file in response to a first write operation on the target data block, wherein the first data value is at least one write value of the target data block before receiving the first write operation; and writes one of the first data values ​​to a target address corresponding to the target data block when a first log file meets a predetermined condition, wherein the predetermined condition includes: the total number of first records is greater than or equal to a first predetermined number of records, wherein the first record is used to record at least one write operation corresponding to the target data block before the first write operation in the first log file; the total number of second records within a predetermined time is greater than or equal to a second predetermined number of records, wherein the second record is used to record multiple write operations corresponding to multiple data blocks in the first log file, thereby solving the problems of complexity and low flexibility of data access and achieving convenience of data access and security of data protection.

[0029] In one implementation, after determining the first data value corresponding to the target data block in response to the first write operation on the target data block in the target file, the method further includes:

[0030] Determining a second data value corresponding to the target data block;

[0031] When the first log file does not satisfy the predetermined condition, the second data value is written into the target address corresponding to the target data block.

[0032] When the first log file does not meet the predetermined conditions, that is, the number of write operations on a single data block does not exceed the limit or the number of write operations on the target file within the predetermined time does not exceed the limit, the second data value corresponding to the write operation is written to the target address corresponding to the target data block in accordance with the conventional writing to the target file. In this way, the editing process of the entire file is granulated to the data block level, which improves the convenience of data access and the efficiency of data processing.

[0033] Figure 2 An embodiment of the present application provides a data processing method, which can be performed by an electronic device. The electronic device may include: a server and / or a terminal device. In other words, the method can be performed by software or hardware installed in the electronic device, and the method includes the following steps:

[0034] S201: Split the target file into multiple data blocks.

[0035] A correspondence between the target file and the plurality of data blocks, and between the plurality of data blocks and a plurality of addresses is established.

[0036] This step can split the file according to the fixed data block length (this value can be set). The file splitting will not change the format and storage method of the data. It only logically divides the file according to the fixed length. It refers to the concept of compression and encryption, but does not perform changes on the data and will not affect the data itself. For example, a data file 1: AXCHXYZQRDEFKLMNS can be split into 6 data blocks according to every 3 characters (that is, the length is set to 3). Blocks 001 to 005 are all 3 characters. Block 006 is less than 3 characters, and only two characters are retained. Then, a correspondence between the target file and the multiple data blocks, and a correspondence between the multiple data blocks and multiple addresses are established to facilitate subsequent data block-level read and write operations on the target file.

[0037] S202: In response to a first write operation on a target data block in a target file, determine a first data value corresponding to the target data block.

[0038] The first data value is at least one write value of the target data block before receiving the first write operation.

[0039] This step can be done using Figure 1 The description of step S102 in the embodiment will not be repeated here for the repeated parts.

[0040] In one implementation, in response to a first write operation on a target data block in a target file, a first log file corresponding to the target file may be first created, and then the initial value corresponding to the target data block may be saved in the first log file as a record. When a write operation is subsequently performed on the target data block, the data value before the current write operation is saved in the first log file. If the target data block is a newly written data block, a new empty data block is created in the target file, and the corresponding initial data value is recorded as an empty value in the first log file. In this way, the first log file records the write operation records for all data blocks of the target file, and saves multiple write values ​​of the corresponding data blocks before each write operation.

[0041] S204: When the first log file meets a predetermined condition, write one of the first data values ​​into a target address corresponding to the target data block.

[0042] The predetermined conditions include:

[0043] The total number of first records is greater than or equal to a first predetermined number of records, wherein the first record is used to record, in the first log file, at least one write operation corresponding to the target data block before the first write operation;

[0044] The total number of second records within the predetermined time is greater than or equal to a second predetermined number of records, wherein the second records are used to record multiple write operations corresponding to multiple data blocks in the first log file.

[0045] This step can be done using Figure 1 The description of step S104 in the embodiment will not be repeated here for the repeated parts.

[0046] For example, as in the aforementioned data file 1, if the data content of block 004 changes, the data DEF in block 004 can be written to the log file corresponding to data file 1 first, and then the new write value, such as AWX, can be written to the address corresponding to block 004 corresponding to data file 1. When the second write operation is performed on block 004, the data AWX in the current block 004 is written to the log file..., if the maximum number of single-block operations is set to 3 times, when block 004 is modified for the third time, the log file already has two write values ​​for block 004: DEF and AWX. The user can select one of the write values, such as DEF, to write back to the address corresponding to block 004, so that the data block can be restored to its initial state. In addition, an alarm can be set if the number of operations on multiple data blocks in a data file exceeds a certain value within a time period: for example, it can be set that if the change to the data file does not exceed 50% within 5 minutes, in this example, the data file 1 initially has 6 split blocks. When more than 3 split blocks are changed (including existing and newly added), one of the multiple write values ​​corresponding to each data block can be written back to the corresponding data block.

[0047] An embodiment of the present application provides a data processing method, which determines a first data value corresponding to a target data block in a target file in response to a first write operation on the target data block, wherein the first data value is at least one write value of the target data block before receiving the first write operation; and writes one of the first data values ​​to a target address corresponding to the target data block when a first log file meets a predetermined condition, wherein the predetermined condition includes: the total number of first records is greater than or equal to a first predetermined number of records, wherein the first record is used to record at least one write operation corresponding to the target data block before the first write operation in the first log file; the total number of second records within a predetermined time is greater than or equal to a second predetermined number of records, wherein the second record is used to record multiple write operations corresponding to multiple data blocks in the first log file. This method can solve the problems of complexity and low flexibility of data access and achieve convenient data access and security of data protection.

[0048] In one implementation, after determining the first data value corresponding to the target data block in response to the first write operation on the target data block in the target file, the method further includes:

[0049] When the first log file meets a predetermined condition, sending an excessive modification prompt message corresponding to the target file to the server;

[0050] When the first log file satisfies a predetermined condition, writing one of the first data values ​​into a target address corresponding to the target data block includes:

[0051] After receiving the write-back instruction for the target data block sent by the server, one of the first data values ​​is written into the target address corresponding to the target data block.

[0052] When the first log file meets the predetermined conditions, an excessive modification prompt message corresponding to the target file is sent to the background server to remind the security management personnel that the file is at risk of being maliciously accessed and whether to write back the file. After receiving the write-back instruction for the target data block sent by the server, one of the first data values ​​is written into the target address corresponding to the target data block.
