[0030] Figure 2 is a flowchart of the data storage method according to the embodiments of the present application. As shown in Figure 2 the method includes the following steps:

[0031] ​Step S201, according to the data importance of a plurality of message packets in a target service and the performance requirement level of each of the message packets to the server, a plurality of RAID levels are determined, and a hard disk group meeting each of the RAID levels is configured for the server, the performance requirement level includes: the requirement level of read-write rate and the requirement level of delay rate, the server is used to execute the target service, and one of the hard disk groups includes at least one hard disk.

[0032] Specifically, the RAID level corresponds to the hard disk group one by one, and a plurality of RAID levels constitute a RAID array of the target service. The target service refers to a specific service or application scenario that needs data storage. The hard disk group is configured according to the requirements of the RAID level, and the appropriate hard disk type, capacity and number are selected, and the hard disks are physically connected and logically configured.

[0033] Specifically, the performance requirement level includes a first level, a second level and a third level, and the performance requirement levels characterized by the first level, the second level and the third level decrease in turn.

[0034] Step S202, in the case that the target message packet sent by the device end is received by the server, according to the data importance, data access frequency and data recovery time target of the target message packet, a security level index is determined, the security level index is an index for evaluating the security level required by the message packet, and the target message packet is part of a plurality of message packets;

[0035] Specifically, the target message packet refers to a specific data unit sent from the device end to the server, and the security level index is calculated based on the data importance, data access frequency and data recovery time target, which is used to evaluate the security level required by the target message packet. Different security levels correspond to different RAID levels.

[0036] Step S203, according to the security level index, a target RAID level is determined from a plurality of RAID levels, and the hard disk group corresponding to the target RAID level is determined as a target hard disk group, and the target message packet is stored by using the target hard disk group, and the target RAID level is one of a plurality of RAID levels.

[0037] Specifically, according to the security level index, a target RAID level is determined from a plurality of RAID levels, and the hard disk group corresponding to the target RAID level is determined, and the target message packet is stored by using the corresponding hard disk group.

[0038] According to the embodiment, first, according to the data importance of the plurality of message packets in the target service and the performance requirements such as read-write speed and delay rate of the server, a plurality of RAID levels are determined, then according to the determined plurality of RAID levels, the corresponding hard disk group is configured for the server, in the case of receiving the target message packet sent by the device end, according to the data importance, data access frequency and data recovery time target of the target message packet, the security level index of the target message packet is determined, finally, according to the security level index, the target RAID level is determined from the plurality of RAID levels, the hard disk group corresponding to the target RAID level is determined as the target hard disk group, and the hard disk group is used to store the target message packet. According to the characteristics and requirements of the data, the RAID level is dynamically selected, the reasonable configuration of the hard disk resources is realized, the full use of the hard disk space of the server is ensured, the waste and uneven use of the hard disk space are avoided, and the utilization rate and efficiency of the hard disk resources are improved.

[0039] In an optional solution, the data importance of the message packet includes a first degree, a second degree and a third degree, the importance degrees represented by the first degree, the second degree and the third degree decrease in turn, after the server is configured with the hard disk group meeting the RAID levels, the method further includes:

[0040] Step S204: according to the data importance of the plurality of message packets, the backup strategy and the backup frequency of the RAID level corresponding to each message packet are determined, the backup strategy includes: in the case that the data importance of the message packet is the first degree, full backup is adopted, in the case that the data importance of the message packet is the second degree, incremental backup is adopted, in the case that the data importance of the message packet is the third degree, differential backup is adopted;

[0041] Specifically, the multiple RAID levels are determined according to the data importance of the multiple message packets in the target service and the performance requirement level of each of the message packets on the server, including: in the case that the data importance of the message packets is the first degree and the performance requirement level is the first level, determining that the multiple RAID levels include RAID10; in the case that the data importance of the message packets is the first degree and the performance requirement level is the second level, determining that the multiple RAID levels include RAID1; in the case that the data importance of the message packets is the first degree and the performance requirement level is the third level, determining that the multiple RAID levels include RAID6; in the case that the data importance of the message packets is the second degree and the performance requirement level is the first level, determining that the multiple RAID levels include RAID5; in the case that the data importance of the message packets is the second degree and the performance requirement level is the second level, determining that the multiple RAID levels include RAID5 or RAID6; in the case that the data importance of the message packets is the second degree and the performance requirement level is the third level, determining that the multiple RAID levels include RAID0; in the case that the data importance of the message packets is the third degree and the performance requirement level is the first level, determining that the multiple RAID levels include RAID0; in the case that the data importance of the message packets is the third degree and the performance requirement level is the second level, determining that the multiple RAID levels include RAID0 or RAID1; in the case that the data importance of the message packets is the third degree and the performance requirement level is the third level, determining that the multiple RAID levels include RAID0.

[0042] Specifically, for the message package with high data importance and high performance requirement level, RAID10 can provide data redundancy and high performance; for the message package with high data importance and medium performance requirement level, RAID1 can provide data redundancy with lower cost; for the message package with high data importance and low performance requirement level, RAID6 can provide data redundancy and high fault tolerance capability, but with poor write performance; for the message package with medium data importance and high performance requirement level, RAID5 can provide data redundancy and better performance; for the message package with medium data importance and medium performance requirement level, RAID5 or RAID6 can be selected according to specific requirements, wherein RAID6 provides higher fault tolerance capability; for the message package with medium data importance and low performance requirement level, RAID0 can improve performance, but does not provide data redundancy, and is suitable for non-critical data; for the message package with low data importance and high performance requirement level, RAID0 can improve performance, and is suitable for scenarios with very high performance requirements but low data security requirements; for the message package with low data importance and medium performance requirement level, RAID0 or RAID1 can be selected according to specific requirements, wherein RAID1 provides data redundancy but with higher cost; for the message package with low data importance and low performance requirement level, RAID0 can improve performance and reduce cost, and is suitable for non-core business data.

[0043] Specifically, full backup specifies complete backup of data, incremental backup refers to backup of data changed since the last backup, differential backup refers to backup of all data changed since the last full backup, and backup frequency and strategy can be adjusted according to target business and data importance.

[0044] Step S205: According to the backup strategy and the backup frequency, set backup parameters of multiple RAID levels.

[0045] Specifically, the set backup parameters include backup strategy, backup frequency and backup window (i.e. time period for performing backup operation).

[0046] Specifically, for data with low importance, a lower backup frequency or incremental backup or differential backup is adopted, which only backs up the data changed since the last backup, reducing the redundancy of the backup data and thus reducing the occupation of system resources and improving the overall performance; for data with high importance, a higher backup frequency or full backup is adopted, which means that each backup will contain a complete data set, thus ensuring that critical data is backed up more frequently and comprehensively, improving the security of the data. Different backup frequencies and strategies are adopted for data of different importance, which can avoid unnecessary frequent backup and redundant storage, make the storage space of the hard disk be reasonably utilized, and further solve the problem of unreasonable allocation of hard disk resources in the prior art.

[0047] In the embodiments, different backup strategies are adopted for different data importance degrees of the message package, which can realize differential backup of different RAID levels, further ensure that the determined backup strategy and backup frequency match the message package of different data importance, and thus further realize the rationalization of the application of hard disk resources.

[0048] In some other example embodiments, a security level index is determined according to the data importance, data access frequency and data recovery time target of the target message package, including:

[0049] According to the first correspondence relationship, a first score is determined as a score corresponding to an importance degree range of the data importance of the target message package, and the first correspondence relationship is a correspondence relationship between the importance degree range and the score;

[0050] According to the second correspondence relationship, a second score is determined as a score corresponding to a frequency range of the data access frequency of the target message package, and the second correspondence relationship is a correspondence relationship between the frequency range and the score;

[0051] According to the third correspondence relationship, a third score is determined as a score corresponding to a time range of the data recovery time target of the target message package, and the third correspondence relationship is a correspondence relationship between the time range and the score;

[0052] The security level index is determined as the sum of the first score, the second score and the third score.

[0053] Specifically, the first correspondence relationship, the second correspondence relationship and the third correspondence relationship are pre-set correspondence relationships, and the importance degree range, the frequency range and the time range are pre-set ranges.

[0054] In the embodiment, the security level index of the data can be more accurately evaluated by comprehensively considering and scoring the data importance, data access frequency and data recovery time target of the target message package, the different RAID levels are selected according to the security level index, the target message package is further stored in a targeted manner, the backup strategy of the target message package is further ensured to meet the security requirement of the target message package, and the security and reliability of the target message package in the system failure are further ensured.

[0055] In addition, the application further presets a corresponding relationship (hereinafter referred to as a fourth corresponding relationship) between the security level index and the RAID level, after obtaining the security level index of the target message package, the RAID level corresponding to the security level index is searched in the fourth corresponding relationship, and the RAID level is the target RAID level. The hard disk group corresponding to the target RAID level is the target hard disk group.

[0056] For example, for the setting of the first correspondence relationship, the second correspondence relationship and the third correspondence relationship, in this application, for data importance, that is, data is crucial to business, and loss or damage will cause significant loss, the threshold is set to 9-10 points; for data importance, that is, data has a certain impact on business, but is not critical, the threshold is set to 5-8 points; for low data importance, that is, data has less impact on business, and loss or damage will not cause serious consequences, the threshold is set to 1-4 points; for high access frequency, that is, the number of daily access is greater than or equal to 1000 times, the threshold is set to 9-10 points; for access frequency, that is, the number of daily access is greater than 100 times and less than 1000 times, the threshold is set to 5-8 points; for low access frequency, that is, the number of daily access is less than 100 times, the threshold is set to 1-4 points; for low recovery time target, that is, the recovery time target is less than or equal to 1 hour, the threshold is set to 9-10 points; for recovery time target, that is, the recovery time target is greater than one hour and less than 12 hours, the threshold is set to 5-8 points; for low recovery time target, that is, the recovery time target is greater than or equal to 12 hours, the threshold is set to 1-4 points. According to the actual situation of the data, score each factor, including data importance, access frequency and recovery time target, and add the scores of each factor to get the total score, and select the RAID level according to the total score. The total score is 24-30 points: select RAID 10 or RAID 1 to ensure high data redundancy and high performance; the total score is 15-23 points: select RAID 5 or RAID 6 to balance performance, redundancy and cost; the total score is 6-14 points: select RAID 0 to reduce cost and improve performance, but need to cooperate with good backup strategy. By considering and scoring the data importance, data access frequency and data recovery time target of the target message package, the security level index of the data can be more accurately evaluated, different RAID levels are selected for backup according to the determined security level index, and the target message package is further stored in a targeted manner, the backup strategy of the target message package is further ensured to meet the security requirements of the target message package, and the security and reliability of the target message package in system failure are further ensured.

[0057] In another optional solution, the server is configured with hard disk groups meeting the RAID levels, including: according to the plurality of RAID levels, the server is configured with hard disks corresponding to the number and capacity of the RAID levels.

[0058] In the embodiment, by configuring the server with hard disks corresponding to the number and capacity of the RAID levels, the RAID levels are reasonably configured, and the configuration of the hard disk resources is further optimized.

[0059] In another alternative, after configuring the server with hard disk groups meeting the RAID levels, the method further comprises: deploying a RAID controller on the server and configuring parameters of the RAID controller, the parameters of the RAID controller including at least one of: a stripe size, a check mode;

[0060] In particular, when configuring the stripe size, the average file size should be considered, if large files such as videos, database files, etc. are mainly processed, a larger stripe size should be selected, if small files such as documents, pictures, etc. are processed, a smaller stripe size should be selected; common check modes include: parity check, cyclic redundancy check, B+ check, etc.

[0061] Mounting the key data on the server to the RAID, the key data including at least one of: a database, a log file.

[0062] In particular, mounting involves the following steps: confirming that the RAID has been correctly configured and is in a usable state, creating a file system on the RAID, creating a mounting point, mounting the RAID, verifying that the RAID has been successfully mounted, etc.

[0063] In the embodiments, by deploying a RAID controller on the server and configuring the stripe size parameter, the size of the data divided into blocks is determined, a reasonable stripe size can not only guarantee the performance of the RAID controller, but also realize the optimized utilization of the storage space, by configuring the check mode of the RAID controller, the RAID controller can detect and correct errors in the data, thereby ensuring the integrity and reliability of the data; mounting the key data on the server to the RAID, thereby ensuring that the data is written to the main server at the same time and is also synchronized to the RAID in real time.

[0064] In some example schemes of the present application, before determining the security level index according to the data importance, data access frequency and data recovery time target of the target message package, the method further comprises:

[0065] Data decoding is performed on the message package to obtain JSON object data in string format;

[0066] Data parsing is performed on the JSON object data to obtain key value information in the JSON object;

[0067] Data verification is performed on the key value information, the data verification including: data integrity verification, data format verification, data content verification and data security verification, the data content verification including: verifying whether the ID of the key value information is from a legal device, whether the key value information is within a preset range and whether the update time of the key value information is within a preset time period.

[0068] Specifically, the message packet is data decoded, data parsed and the results of the processing are data verified.

[0069] In the embodiment, the server ensures that the data can be correctly identified through the decoding and parsing process of the data, helps the server to accurately understand the data content sent by the device end, and provides accurate information basis for subsequent data processing; through the data integrity verification, it is checked whether the decoded and parsed data contains all necessary fields, and the hash value of the JSON object is compared with the expected hash value, to ensure that the data is not tampered or lost in the transmission process; through the format verification of the data, it is helpful to prevent data processing errors caused by format errors; through the content verification of the data, it is helpful to prevent illegal devices from sending data or abnormal data from devices, thereby maintaining the security and stability of the system; through the data security verification, it is ensured that only legal devices can send messages, preventing data from being eavesdropped and tampered with in the transmission process, protecting information from being leaked, and maintaining data security. Through decoding, parsing and verifying the data, the type and characteristics of the data can be more accurately identified, the scoring of the message packet is more accurate, and the security level index of the message packet is more accurate, further optimizing the configuration of the hard disk resources.

[0070] Exemplarily, taking the target message packet as a state update message of a smart bulb as an example, the specific processes of the data decoding, the data parsing and the data verification in the present application are described as follows: the server receives a state update message from the smart bulb through the MQTTBroker, the message format is JSON, and the message contains the ID, the current brightness, the color temperature and other information of the bulb; the server parses the payload part of the MQTT message, and converts it from binary format to JSON object in string format; the fields of the bulb ID (bulb_id), the current brightness (brightness) and the color temperature (color_temp) are extracted from the JSON object. The values of these fields are converted into appropriate types, for example, the brightness is converted from a string to an integer; it is checked whether the brightness value is within the valid range (for example, 0-255), and whether the color temperature value is within the valid range (for example, 1500K-9000K, but the specific range may vary according to the bulb model), and if an invalid value is found, it is replaced with a default value or an error log is recorded; the parsed and cleaned data is stored in the database. The database table contains fields such as bulb ID, brightness, color temperature, update time, etc.; transaction processing is used to ensure the atomicity and consistency of the data; it is checked whether the payload part of the MQTT message contains all the necessary fields (such as bulb_id, brightness, color_temp); the hash value of the JSON object is calculated and compared with the expected hash value to verify the integrity of the data; the format of the JSON object is verified, including whether the field names are correct, whether the data types match, etc.; the JSON Schema is used for format verification to ensure that the message conforms to the expected format specification; it is verified whether the bulb ID exists in the database to ensure that the message comes from a legal device; it is checked whether the brightness and color temperature values are within a reasonable range to prevent abnormal data from being sent by the device; it is verified whether the update time of the message is reasonable to prevent timestamp forgery; the username and password of MQTT are used for identity verification to ensure that only legal devices can send messages; the MQTT connection is encrypted using TLS / SSL to prevent data from being eavesdropped or tampered with during transmission; when sensitive information (such as device keys) is stored in the database, encryption technology is used to protect the security of the data; the average response time of the server processing the MQTT message is measured to ensure that the data processing is completed within a reasonable time range; the performance indicators of the database (such as query response time, write throughput, etc.) are monitored to ensure that the database can handle high-concurrency requests; a stress testing tool is used to simulate a scenario in which a large number of devices send messages simultaneously to verify the performance and stability of the server.

[0086] The first determining unit 10 is configured to determine a plurality of RAID levels according to data importance of a plurality of message packets in a target service and a performance requirement level of each of the message packets to a server, and configure the server with hard disk groups satisfying each of the RAID levels, wherein the performance requirement level comprises a requirement level of read-write speed and a requirement level of delay rate, the server is configured to execute the target service, and each of the hard disk groups comprises at least one hard disk.

[0087] Specifically, the RAID levels correspond to the hard disk groups one by one, and the plurality of RAID levels constitute a RAID array of the target service. The target service refers to a specific service or application scenario requiring data storage. The hard disk groups are configured according to the requirements of the RAID levels, and appropriate hard disk types, capacities and quantities are selected, and the hard disks are physically connected and logically configured.

[0088] The second determining unit 20 is configured to determine a security level indicator according to data importance, data access frequency and data recovery time target of a target message packet when the server receives the target message packet sent by a device end, wherein the security level indicator is an indicator for evaluating a required security level of the message packet, and the target message packet is part of the plurality of message packets.

[0089] Specifically, the target message packet refers to a specific data unit sent from the device end to the server, and the security level indicator is calculated based on data importance, data access frequency and data recovery time target, and is used to evaluate the required security level of the target message packet. Different security levels correspond to different RAID levels.

[0090] The storage unit 30 is configured to determine a target RAID level from the plurality of RAID levels according to the security level indicator, determine a target hard disk group corresponding to the target RAID level as a target hard disk group, and store the target message packet in the target hard disk group, wherein the target RAID level is one of the plurality of RAID levels.

[0091] Specifically, the target RAID level is determined from the plurality of RAID levels according to the security level indicator, and the target hard disk group corresponding to the target RAID level is determined, and the target message packet is stored in the corresponding hard disk group.

[0092] According to the embodiment, the first determining unit determines the plurality of RAID levels according to the data importance of the plurality of message packets in the target service and the performance requirements such as read-write speed and delay rate of the server, and configures the corresponding hard disk group for the server according to the determined plurality of RAID levels; in the case that the target message packet is received from the device end, the second determining unit determines the security level index of the target message packet according to the data importance, data access frequency and data recovery time target of the target message packet; the storage unit determines the target RAID level from the plurality of RAID levels according to the security level index, and determines the hard disk group corresponding to the target RAID level as the target hard disk group. According to the characteristics and requirements of the data, the application dynamically selects the RAID level, realizes the reasonable configuration of the hard disk resources, guarantees the full use of the hard disk space of the server, avoids the waste and unbalanced use of the hard disk space, and improves the utilization rate and efficiency of the hard disk resources.

[0093] In another alternative, the apparatus further comprises:

[0094] The third determining unit is configured to determine the backup strategy and backup frequency of the RAID level corresponding to each message packet according to the data importance of the plurality of message packets, wherein the backup strategy comprises: full backup in the case that the data importance of the message packet is the first degree, incremental backup in the case that the data importance of the message packet is the second degree, and differential backup in the case that the data importance of the message packet is the third degree.

[0095] Specifically, the full backup specifies complete backup of data at a specified period, the incremental backup refers to backup of data changed since the last backup, and the differential backup refers to backup of all data changed since the last full backup. The backup frequency and strategy can be adjusted according to the target service and data importance.

[0096] The setting unit is configured to set the backup parameters of the plurality of RAID levels according to the backup strategy and the backup frequency.

[0097] Specifically, the set backup parameters comprise backup strategy, backup frequency and backup window (i.e. the time period for performing backup operation).

[0098] In the embodiment, different backup strategies are adopted for different data importance degrees of the message packet, which can realize differential backup of different RAID levels, and further guarantee that the determined backup strategy and backup frequency match the message packet with different data importance, thereby further realizing the rational application of the hard disk resources.

[0099] Specifically, for data with low importance, a lower backup frequency or incremental backup or differential backup is adopted, which only backs up the data changed since the last backup, reduces the redundancy of the backup data, thereby reducing the occupation of system resources and improving the overall performance; for data with high importance, a higher backup frequency or full backup is adopted, which means that each backup will contain a complete data set, thereby ensuring that critical data is backed up more frequently and comprehensively, improving the security of the data. Different backup frequencies and strategies are adopted for data of different importance, which can avoid unnecessary frequent backup and redundant storage, make the storage space of the hard disk be reasonably utilized, and further solve the problem of unreasonable hard disk resource configuration in the prior art.

[0100] In some other example embodiments, the second determining unit comprises:

[0101] The first determining module is configured to determine, according to a first correspondence relationship, a first score as a score corresponding to an importance degree range of the data importance of the target message package, the first correspondence relationship being a correspondence relationship between an importance degree range and a score.

[0102] The second determining module is configured to determine, according to a second correspondence relationship, a second score as a score corresponding to a frequency range of the data access frequency of the target message package, the second correspondence relationship being a correspondence relationship between a frequency range and a score.

[0103] The third determining module is configured to determine, according to a third correspondence relationship, a third score as a score corresponding to a time range of the data recovery time target of the target message package, the third correspondence relationship being a correspondence relationship between a time range and a score.

[0104] The fourth determining module is configured to determine the security level indicator as a sum of the first score, the second score and the third score.

[0105] Specifically, the first correspondence relationship, the second correspondence relationship and the third correspondence relationship are pre-set correspondence relationships, and the importance degree range, the frequency range and the time range are pre-set ranges.

[0106] In the embodiments, the security level indicator of the data can be more accurately evaluated by comprehensively considering and scoring the data importance, the data access frequency and the data recovery time target of the target message package, and the target message package is stored more targetedly by selecting different RAID levels according to the determined security level indicator, thereby further ensuring that the backup strategy of the target message package meets the security requirement of the target message package, and further ensuring the security and reliability of the target message package in the case of system failure.

[0107] In addition, the application also presets a corresponding relationship (hereinafter referred to as the fourth corresponding relationship) between the security level index and the RAID level, and after obtaining the security level index of the target message package, the RAID level corresponding to the security level index is searched in the fourth corresponding relationship, and the RAID level is the target RAID level. The hard disk group corresponding to the target RAID level is the target hard disk group.

[0108] Exemplarily, for the setting of the first corresponding relationship, the second corresponding relationship and the third corresponding relationship, in the application, for data with high importance, i.e. data is crucial to business, and loss or damage will cause significant loss, the threshold is set to 9-10 points; for data with medium importance, i.e. data has a certain influence on business, but is not critical, the threshold is set to 5-8 points; for data with low importance, i.e. data has less influence on business, and loss or damage will not cause serious consequences, the threshold is set to 1-4 points; for high access frequency, i.e. the number of daily accesses is greater than or equal to 1000 times, the threshold is set to 9-10 points; for medium access frequency, i.e. the number of daily accesses is greater than 100 times and less than 1000 times, the threshold is set to 5-8 points; for low access frequency, i.e. the number of daily accesses is less than 100 times, the threshold is set to 1-4 points; for low recovery time target, i.e. the recovery time target is less than or equal to 1 hour, the threshold is set to 9-10 points; for medium recovery time target, i.e. the recovery time target is greater than one hour and less than 12 hours, the threshold is set to 5-8 points; for high recovery time target, i.e. the recovery time target is greater than or equal to 12 hours, the threshold is set to 1-4 points. According to the actual situation of the data, score each factor, including data importance, access frequency and recovery time target, and add the scores of each factor to obtain the total score, and select the RAID level according to the total score. Total score: 24-30 points: select RAID 10 or RAID 1 to ensure high data redundancy and high performance; total score: 15-23 points: select RAID 5 or RAID 6 to balance performance, redundancy and cost; total score: 6-14 points: select RAID 0 to reduce cost and improve performance, but need to cooperate with good backup strategy. Through comprehensive consideration and scoring of the data importance, data access frequency and data recovery time target of the target message package, the security level index of the data can be more accurately evaluated, different RAID levels are selected for backup through the determined security level index, and the target message package is further stored in a targeted manner, the backup strategy of the target message package is further ensured to meet the security requirements of the target message package, and the security and reliability of the target message package in the case of system failure are further ensured.

[0109] In another alternative, the first determining unit comprises a configuration module configured to configure the server with hard disks of a quantity and capacity corresponding to each of the RAID levels according to the plurality of RAID levels, and the apparatus further comprises a deployment unit configured to deploy a RAID controller on the server and configure parameters of the RAID controller after the server is configured with the hard disk groups satisfying each of the RAID levels, the parameters of the RAID controller including at least one of a stripe size and a check mode.

[0110] In particular, when configuring the stripe size, the average file size should be considered, if large files such as videos, database files, etc. are mainly processed, a larger stripe size should be selected, and if small files such as documents, pictures, etc. are processed, a smaller stripe size should be selected; common check modes include parity check, cyclic redundancy check, B+ check, etc.

[0111] The mounting unit is configured to mount critical data on the server to the RAID, the critical data including at least one of a database and a log file.

[0119] In the embodiments, the server ensures that the data can be correctly identified through the decoding and parsing processes, helps the server accurately understand the data content sent by the device end, and provides an accurate information basis for subsequent data processing. Through data integrity verification, it is checked whether the decoded and parsed data contains all necessary fields, and the hash value of the JSON object is compared with the expected hash value to ensure that the data is not tampered with or lost during transmission. Through format verification of the data, it helps to prevent data processing errors caused by format errors. Through content verification of the data, it helps to prevent illegal devices from sending data or abnormal data from being sent by devices, thereby maintaining the security and stability of the system. Through data security verification, it is ensured that only legal devices can send messages, preventing data from being eavesdropped and tampered with during transmission, protecting information from being leaked, and maintaining data security. Through decoding, parsing, and verification of the data, the type and characteristics of the data can be more accurately identified, making the scoring of the message packet more accurate, and thus the security level index of the message packet more accurate, further optimizing the configuration of the hard disk resources.
