Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

FIG. 1 shows a schematic flowchart of a data information scanning method according to an embodiment of the present invention. As shown in Figure 1, the method includes:

Step S110: Determine whether the data information to be scanned meets the preset compression condition according to the information capacity of the data information to be scanned.

Wherein, the preset compression condition can be flexibly set, and the present invention does not limit the specific setting manner. For example, the capacity threshold can be set in advance according to the total memory capacity, the information capacity can be compared with the capacity threshold, and whether the data information to be scanned meets the preset compression conditions can be determined according to the comparison result. Compare the available memory capacity, and determine whether the data information to be scanned meets the preset compression conditions according to the comparison result.

Step S120: If yes, compress the data information to be scanned, and load the compressed data information into the memory.

When it is determined that the data information to be scanned meets the preset compression condition, the data information to be scanned is compressed, and the compressed data information is loaded into the memory. Among them, various compression algorithms can be flexibly used for compression, as long as the purpose of reducing the file size can be achieved. In this embodiment, the file can be compressed in the hard disk first and then loaded into the memory, or it can be directly compressed while being loaded in the memory.

Step S130: Decompress the compressed data information loaded in the memory.

This step can be executed immediately after step S120 is executed, or can be executed as required after step S120 is executed. For example, the decompression process may also be performed on the part of the data information when the corresponding data information needs to be used.

Step S140: Analyzing the decompressed data information to determine the scanning result of the data information to be scanned.

Through this step, analytical scanning can be performed after the decompression is completed, so as to determine the scanning result. This method compresses the data information and only loads the compressed data information in the memory, thereby avoiding the problem that the data information cannot be scanned due to too large data information, making the scanning method applicable to various large files and broadening the business application Scenes.

According to the scanning method of data information provided in this embodiment, when it is judged according to the information capacity of the data information to be scanned that the data information to be scanned meets the preset compression conditions, the data information to be scanned is compressed, and the compressed data information is Loading into the memory; analyzing the compressed data information loaded in the memory after decompression, so as to determine the scanning result of the data information to be scanned. It can be seen that this method compresses the data information and only loads the compressed data information in the memory, thereby avoiding the problem that the data information cannot be scanned due to too large data information, so that the scanning method can be applied to various large files. Broaden the business application scenarios.

Fig. 2 shows a schematic flowchart of a data information scanning method according to another embodiment of the present invention. In this embodiment, the data information is updated data information as an example for description. The update data information may be information in the form of an update package to be downloaded, and is used to implement a software or system update function. Of course, in other embodiments of the present invention, the data information may also be vulnerability repair data information, for example, data information in the form of a patch package, etc., for realizing the automatic repair function. As shown in Figure 2, the method includes:

Step S210: Determine whether the data information to be scanned meets the preset compression condition according to the information capacity of the data information to be scanned.

Since this embodiment is mainly used to reduce the memory occupation to facilitate the scanning of large files, the preset compression conditions can be set according to the information capacity of the data information to be scanned and the memory information. Two possible implementations of preset compression conditions are described below:

In the first implementation manner, the capacity threshold is set in advance according to the total memory capacity, the information capacity is compared with the capacity threshold, and whether the data information to be scanned meets the preset compression condition is determined according to the comparison result. Specifically, if the total memory capacity is large, the capacity threshold may be set larger; otherwise, the capacity threshold may be set smaller. Correspondingly, when the information capacity is greater than the capacity threshold, it is determined that the data information to be scanned meets the preset compression condition. In addition, the capacity threshold may also be set in combination with external conditions such as scanning frequency. This implementation is equivalent to setting a capacity threshold in advance, and all data information larger than the capacity threshold needs to be compressed.

In the second implementation manner, the available memory capacity can be dynamically obtained, the information capacity is compared with the available memory capacity, and whether the data information to be scanned meets the preset compression condition is determined according to the comparison result. Specifically, whenever the data information to be scanned is obtained, the current available memory capacity is obtained in real time, and then it is dynamically determined whether the preset compression condition is met according to the comparison result between the data information to be scanned and the current available memory capacity. For example, if the ratio or difference between the data information to be scanned and the current available memory capacity meets a certain condition, it is determined that the preset compression condition is met. In fact, a dynamically adjustable threshold can be set according to the ratio or difference between the data information to be scanned and the current available memory capacity, and determine whether the preset compression condition is met according to the threshold. This method can dynamically adjust the compression conditions so that the current compression conditions are more in line with the current system state.

In practical applications, the above two implementation manners may be used alone or in combination, which is not limited in the present invention.

Step S220: If yes, divide the data information to be scanned into multiple data blocks; compress each data block respectively to obtain a compressed data block, and establish a data block index for the compressed data block; The data blocks are loaded into the memory, and an index file is generated based on the data block index.

When it is determined that the data information to be scanned meets the preset compression condition, the data information to be scanned is compressed, and the compressed data information is loaded into the memory.

Specifically, in this embodiment, in order to facilitate the split processing of large files to achieve the effect of saving memory space, before performing compression on the data information, the data information to be scanned is divided into multiple data blocks in advance, and respectively Each data block is compressed to obtain each compressed data block, and each compressed data block is loaded into the memory. Wherein, when dividing the data block, the division may be performed according to various factors such as information size, content type, and usage frequency of each part included in the data information. After division, compression processing is performed on each data block, so as to realize targeted decompression operation in the subsequent process.

In addition, in order to facilitate targeted decompression operations in the subsequent process and improve information query efficiency, in this embodiment, a data block index is further established for the compressed data block, and an index file is generated according to the data block index. For example, when a piece of data information is divided into five data blocks, a data block index is set for each compressed data block, and the five data block indexes are stored in the index file, so as to quickly locate the corresponding data piece.

Step S230: Obtain each compressed data block according to each data block index included in the index file, and decompress each acquired data block respectively.

This step can be executed immediately after step S220 is executed, or can be executed as required after step S220 is executed.

For example, in a specific business scenario, the scanning engine will process as follows:

First, load all the data information to be scanned into the memory. This process corresponds to step S210 and step S220. During this process, it is necessary to scan the basic attributes of each data information, such as file size, file type, file update time, etc.; all data information is loaded into the memory according to the basic attributes. For example, during this process, it may be determined whether the files need to be compressed, and the files that do not need to be compressed are loaded preferentially; and/or, the files that do not need to be compressed are stored separately from the files that need to be compressed. In this step, if it is judged that a file conforms to the preset compression rule, it is compressed and then stored in memory to save memory space.

Then, according to the preset processing sequence, the required processing data information is obtained from the memory and the scanning processing is performed. This process corresponds to step S230. Wherein, the preset processing order may be various order rules such as prioritizing data that does not need to be compressed, and then processing data that needs to be compressed. It can be seen that this process is realized on demand in essence, and the next data information to be scanned is obtained from the memory according to the current processing progress. When obtaining it, consider that if some large files are fully decompressed, the size of the file may be larger than the remaining available space in the memory. Even if it is not larger than the remaining available space in the memory, the system operation efficiency may be affected due to excessive memory usage. In order to solve this problem, in this process, each compressed data block is obtained respectively according to each data block index contained in the index file, and each obtained data block is respectively decompressed. For example, assuming that a complete compressed data message contains 10 data blocks in total, if 10 data blocks are decompressed into the memory for processing at the same time, the memory consumption will be too large. Therefore, according to the actual processing needs, only one data block is decompressed at a time Or two or three data blocks, thereby reducing the memory consumption at the same time, and can effectively prevent the phenomenon of scanning failure caused by too large data information.

Step S240: Analyzing each decompressed data block to determine the scanning result of the data information to be scanned.

Wherein, whenever step S230 is executed and a data block is obtained, the decompressed data block is analyzed through this step to obtain an analysis result of the data block. Finally, the overall scanning result of the data information to be scanned can be determined according to the analysis results of each data block included in the data information.

It can be seen that this embodiment can effectively reduce the memory occupation of large files by performing compression processing in memory (conventional compression processing is all implemented in the hard disk) and directly storing compressed files in memory. Improve system operating efficiency. Moreover, since compressed files can be decompressed according to data blocks, there is no need to decompress all data information at once, so the amount of memory occupied by large files during scanning is significantly reduced, even if the file size is larger than the remaining space of the memory, it can also be used in this way The scanning function is completed, thereby broadening the application range of the scanning function, so that some applications that are originally limited by the memory space and cannot use the scanning function can also implement the scanning function, thereby providing users with more comprehensive services. This method is especially suitable for scanning and updating scenarios. Since the update library is very large, the traditional scanning solution cannot be used for scanning the update library. After adopting the solution in the present invention, this problem can be effectively solved.

In addition, those skilled in the art may make various possible modifications or extensions to the above embodiments. For example, before performing the step of judging whether the data information to be scanned meets the preset compression condition according to the information capacity of the data information to be scanned, the following steps may be further included:

Monitoring whether a shutdown command is received; if so, intercepting the shutdown command, and performing the above step of judging whether the data information to be scanned meets the preset compression condition according to the information capacity of the data information to be scanned.

Since the files to be scanned must be loaded into the memory to be scanned, it will take up a lot of memory and consume a lot of resources during the scanning process, affecting the use of the computer or even making it unusable, thus affecting the normal use of the computer by the user. In order to solve the above problem, the scanning process can be started after the user finishes using the computer and triggers a shutdown command. When monitoring whether a shutdown command is received, the shutdown function used to send the shutdown command can be determined in advance, and then the above shutdown function can be monitored through the hook function or other types of functions that can be associated with the shutdown function. By monitoring the shutdown function, it can be timely to monitor whether a shutdown command is received. If so, the interception operation may be performed by suspending the transmission of the shutdown command.

Optionally, after the step of intercepting the shutdown command, in order to save resources and improve processing speed, further mark a process unrelated to the scanning operation as a target process, and end the target process. For example, processes irrelevant to various vulnerability repair operations such as documents and browsers opened on the computer can be marked as target processes, and the above-mentioned target processes can be terminated. By shutting down processes that are not related to the vulnerability repair operation, the efficiency of performing the vulnerability repair operation can be improved, and the time taken for the repair can be reduced. After the target process is finished, execute the step of judging whether the data information to be scanned meets the preset compression condition according to the information capacity of the data information to be scanned and subsequent steps, and finally when it is detected that the data information to be scanned has been scanned, Execute the release operation for the above shutdown command. Specifically, the release operation may be performed by resuming the transmission of the shutdown command. After the system receives the transmitted shutdown command, it can perform a shutdown operation to shut down.

Through the above execution steps, the data information scanning process can be started when the user does not use the computer and triggers a shutdown command, which avoids affecting the normal use of the computer by the user due to the scanning data information occupying a large amount of computer memory and resources when the user is using the computer. , thus greatly improving the user experience.
