Description

Technical Field

[0001] This invention relates to the field of device identification technology, specifically to a storage device identification method, electronic device, and storage medium based on data security. Background Technology

[0002] Storage device identification refers to the process by which a computer system identifies and confirms storage devices, including hardware-level identification, operating system-level identification, and device management software-level identification. Hardware-level identification refers to the chipset and BIOS on the server motherboard being responsible for identifying and managing storage devices. Operating system-level identification refers to the server's operating system further identifying and managing storage devices once hardware-level identification is completed. Device management software-level identification refers to the use of device management software to further identify and manage storage devices in some large server environments.

[0003] Existing improvements for storage device identification typically address identification methods under various access states. For example, they might store the target storage device's identification information in a shortcut, comparing the accessed storage device's identification information with the stored shortcut to identify the device. While this method can effectively identify storage devices under various access states, it relies solely on comparison of identification information. Furthermore, it requires creating a shortcut and storing the identification information within it, making the process cumbersome and resulting in slow identification efficiency and low security. For instance, in publication number CN111198830A... The patent application discloses a method, apparatus, electronic device, and storage medium for identifying mobile storage devices. This solution achieves the ability to identify the target mobile storage device even when its access status changes, by receiving a trigger operation on the shortcut icon, thus allowing the shortcut icon to function normally. Other improvements for storage device identification typically involve obtaining the corresponding identification code based on the basic information of the storage device and performing the corresponding identification. However, this improvement method still suffers from limitations such as a relatively simple identification method and the ease with which the identification code corresponding to the storage device can be cracked, leading to security risks and low identification security during the identification process. Therefore, it is necessary to improve the existing methods for identifying storage devices. Summary of the Invention

After data α is output from all hard drives SY, the average time taken for all hard drives to output data α is recorded as the output time average. Let v1 be the storage characteristic of the storage device, where t1 is the average input time, t2 is the average output time, v1 is the average input storage, and v2 is the average output storage.

[0022] Furthermore, security device characteristics and storage characteristics are used to identify and back up storage devices, and twin storage devices are obtained based on the backup results; differential analysis is performed on the twin storage devices, and the distinguishing parameters of the storage devices containing twin storage devices are obtained based on the processing results, including:

[0023] Create an R-row × 3-column table, denoted as the identification backup table. In the top row of the identification backup table, except for the first cell, fill in the security device characteristics and storage characteristics in order. In the leftmost column, except for the top cell, fill in the names of all the recorded storage devices in order.

[0024] Fill the security device characteristics and storage characteristics of all recorded storage devices into the identification backup table; when the security device characteristics of any storage device β in the identification backup table are the same as the security device characteristics of storage device γ, record storage device γ as the twin storage device of storage device β.

[0026] Furthermore, differential analysis is performed on the twin storage devices, and the distinguishing parameters for storage devices containing twin storage devices are obtained based on the processing results, including:

[0027] When any storage device other than storage device γ has the same storage characteristics as storage device γ, the storage device with the same storage characteristics as storage device γ is denoted as the anchor device.

Storage device β may have multiple distinguishing parameters.

[0029] Furthermore, when identifying storage devices, security screening is performed on the storage devices to be identified based on data security, and identification of storage devices is performed based on distinguishing parameters, including:

[0030] When identifying storage devices, the storage devices being identified are recorded as devices to be identified; the storage characteristics of the devices to be identified are obtained using a storage characteristic acquisition method and recorded as identification storage characteristics; storage devices whose storage characteristics in the identification backup table are equal to the identification storage characteristics are recorded as devices to be confirmed.

[0031] When the number of devices to be verified is 1: the data security screening software is used to perform security screening on the device to be identified, and the security device characteristics of the device to be identified are obtained during the security screening based on the security device characteristic acquisition method; when the security device characteristics of the device to be identified are equal to the security device characteristics of the device to be verified, the device to be identified is identified as the device to be verified; when the security device characteristics of the device to be identified are not equal to the security device characteristics of the device to be verified, the device to be identified is identified as an unrecorded device.

[0035] Thirdly, this application provides a storage medium on which a computer program is stored, which, when executed by a processor, performs the steps of the method described above.

[0036] The beneficial effects of this invention are as follows: This application first performs security screening on the existing data in the storage device and obtains security device characteristics during the security screening; based on the security device characteristics, the storage device is pre-identified, and based on the pre-identification results, the storage characteristics of the security device are obtained. The advantage of this is that by obtaining the security device characteristics and the storage characteristics, it is possible to obtain the features that can be extracted when the storage device is subjected to security screening and the features that can be extracted when it is not subjected to security screening, respectively. This ensures that when identifying the storage device, identification can be prioritized based on the security device characteristics when security screening is possible, and identification can be based on the storage characteristics when security screening is not possible. At the same time, the obtained security identification features and device features are parameters that are more unique and consistent with the actual characteristics of the storage device compared with other storage devices, ensuring that the identification process of the storage device will not be easily cracked due to the relatively simple identification method. In addition, since the security device characteristics are obtained during the security screening, the identification of the storage device can be completed during the security screening, ensuring that there are no security risks in the identification process. Furthermore, the combination of security screening and device identification improves both identification efficiency and identification security.

[0037] This application also uses security device characteristics and storage characteristics to identify and back up storage devices, and obtains twin storage devices based on the backup results; it performs difference analysis on the twin storage devices, and obtains the distinguishing parameters of the storage devices containing twin storage devices based on the processing results; finally, when identifying storage devices, it performs security screening on the storage devices to be identified based on data security, and identifies the storage devices based on the distinguishing parameters. The advantage of this is that by obtaining twin storage devices and performing difference analysis to obtain distinguishing parameters, it is possible to effectively distinguish storage devices with the same security device characteristics, preventing identification errors caused by the same security device characteristics during identification.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1, please refer to Figure 1 As shown, this application provides a storage device identification method based on data security, including the following steps:

[0044] Step S1: Perform security screening on the existing data in the storage device and obtain security device characteristics during the security screening; pre-identify the storage device based on the security device characteristics and obtain the storage characteristics of the security device based on the pre-identification results;

[0045] Step S1 includes: Step S101, designating the storage hard disks within the storage device as Device Hard Disk SY1 to Device Hard Disk SY2 respectively. n Obtain existing data security screening software, and use the software to screen hard drives SY1 through SY2 respectively. n Perform security screening; for any device hard drive SY c SY device hard drive c The capacity is recorded as the total hard drive capacity. The device hard drive SY c The capacity occupied by the data in the middle is recorded as the total data capacity, and the value of dividing the total data capacity by the total hard disk capacity is recorded as the data percentage.

[0046] In the specific implementation process, the actual acquisition of the device hard disk SY can be based on the independent hard disks in the storage device. For example, the hard disks in the storage device may include mechanical hard disks, solid-state drives, hybrid hard disks, and network hard disks; then, the mechanical hard disks and solid-state drives that are mutually exclusive can be recorded as two device hard disks SY respectively.

[0047] Step S102: Establish a Cartesian coordinate system, denoted as the screening analysis coordinate system. The X-axis of the screening analysis coordinate system is in units of time, and the Y-axis is a number axis with corresponding values ​​of... G0 is a data security screening software that checks the device's hard drive for SY. c When conducting security screening, the ratio of the amount of data screened to the total data volume is used, where G1 represents the data percentage.

[0048] In specific implementation, for example, in a data processing scenario, if the total data capacity corresponding to hard drive SY on a single device is 100TB and the total hard drive capacity is 200TB, then the data proportion can be calculated to be 0.5. Simultaneously, the obtained screening curve SQ is as follows: Figure 2As shown, curve SQ is the screening curve SQ, point MI is the slowest screening point, and point MA is the fastest screening point. Figure 2 The line connecting point MI and point MA does not intersect with the screening curve SQ, meaning the number of screening fluctuation points is 0. In this case, the fluctuation feature algorithm cannot be calculated. Therefore, in this embodiment, when the number of screening fluctuation points is 0, the security hard disk feature is set to 0.

[0049] Step S103, when the data security screening software starts SY on the device hard drive c After data screening, corresponding curves are plotted in the screening analysis coordinate system based on real-time data, until the device hard drive SY... c After completing the screening, the resulting curve is denoted as the screening curve SQ. c ;

[0050] Step S104, the screening curve SQ c The points with the highest and lowest slopes in the curve are denoted as the fastest and slowest screening points, respectively. Connect the fastest and slowest screening points, and intersect the line with the screening curve SQ. c The intersection points are recorded as screening fluctuation points, and the number of screening fluctuation points is recorded as the screening fluctuation point count; the fluctuation feature algorithm is used to obtain the device hard drive SY. c The corresponding secure hard drive characteristics and fluctuation characteristic algorithm are as follows: Where F1 represents the characteristics of a secure hard drive, m represents the number of fluctuation points to be screened, and f i Let X be the slope corresponding to the i-th screening fluctuation point. i Let x be the x-coordinate of the i-th screening fluctuation point;

[0051] For example, in a data processing session, if the number of screening fluctuation points is 1, the coordinates of the screening fluctuation point are (20, 3), and the slope of the screening fluctuation point is 2, then the number of screening fluctuation points is 1. By calculation, the security hard drive feature is 2 / 3. By obtaining the security hard drive feature, based on the speed at which each device hard drive is security screened, the feature corresponding to each device hard drive can be obtained, thereby ensuring that the obtained security device feature can match the status of all device hard drives within the security device feature.

[0052] Step S105: Obtain the hard drive SY data for all devices. c The corresponding secure hard drive characteristics are used, and a comprehensive hard drive algorithm is employed to obtain the secure device characteristics of the storage device. The comprehensive hard drive algorithm is as follows: Among them, F2 represents the safety equipment characteristic, and H... j The security hard drive characteristics of the j-th device hard drive SY. The average value of the security hard drive characteristics of all device hard drives SY;

[0053] In a specific implementation process, for example, during a data processing session, if the security hard drive characteristics of all the device's hard drives are obtained as 0.5, 1, 1, 0.5, and 2 respectively, then calculations can be performed to obtain... F1 is 1, F2 is 0.3; therefore, the security device characteristic of the storage device can be set to 0.3.

[0054] Step S106: Obtain and record the security device characteristics of all identifiable storage devices; set the pre-identification criteria of the recorded storage devices as the corresponding security device characteristics of the storage devices;

[0055] Step S107: For any recorded storage device: simultaneously input data α to all device hard disks SY of the storage device, and record the average instantaneous read / write rate of all device hard disks SY at the start of data input as the input storage average; after data α is input to all device hard disks SY, record the average time of inputting data α to all device hard disks SY as the input time average, and output data α from all device hard disks SY.

[0056] Step S108: Record the average instantaneous read / write rate of all device hard disks SY at the start of data output as the output storage average. After data α is output from all device hard disks SY, record the average time taken for all device hard disks to output data α as the output time average. Let v1 be the storage characteristic of the storage device, where t1 is the average input time, t2 is the average output time, v1 is the average input storage, and v2 is the average output storage.

[0057] In the specific implementation process, data α is only used to obtain storage characteristics. Data α can be set according to the actual situation. At the same time, it should be ensured that the data input and output are data α when obtaining storage characteristics of the storage device in the future. For example, in the process of obtaining storage characteristics, if the average input storage is 2mb / s, the average output storage is 4mb / s, the average input time is 20s, and the average output time is 10s, then the storage characteristic of the storage device can be calculated to be 1.5.

[0058] Step S109: Obtain the storage characteristics corresponding to all recorded storage devices.

[0059] Step S2: Use security device features and storage features to identify and back up the storage device, and obtain the twin storage device based on the backup results; perform difference analysis on the twin storage device, and obtain the distinguishing parameters of the storage device containing the twin storage device based on the processing results;

[0060] Step S2 includes: Step S201, creating a table of R rows × 3 columns, denoted as the identification backup table, wherein the top row of the identification backup table, except for the first cell, is filled with security device characteristics and storage characteristics in sequence, and the leftmost column, except for the top cell, is filled with the names of all recorded storage devices in sequence.

[0061] Step S202: Fill the security device characteristics and storage characteristics of all recorded storage devices into the identification backup table; when the security device characteristics of any storage device β in the identification backup table are the same as the security device characteristics of storage device γ, record storage device γ as the twin storage device of storage device β.

[0062] In the specific implementation process, the value of R is the value corresponding to the number of storage devices plus 1. For example, if the number of storage devices analyzed in one analysis is 10, then the value of R should be 11. For example, if the identification backup table is established after one data analysis as shown in Table 1: Identification Backup Table, then through analysis, it can be found that storage device A and storage device C have the same security device characteristics. Storage device A can be recorded as a twin storage device of storage device C, or storage device C can be recorded as a twin storage device of storage device A.

[0064] Safety equipment characteristics Storage characteristics Storage device A 0.5 2 Storage device B 0.3 1.4 Storage device C 0.5 1.6 Storage device D 1.3 5

[0065] The purpose of acquiring twin storage devices is to effectively distinguish storage devices with the same security device characteristics, and to prevent identification errors caused by the similarity of security device characteristics during identification.

[0066] Step S203: Perform differential analysis on storage device γ; the differential analysis is as follows: when the storage characteristics of storage device γ are different from the storage characteristics of all other storage devices, the storage characteristics of storage device γ are recorded as the distinguishing parameter of storage device β.

[0067] In the specific implementation process, for example, during a data processing, the identification backup table obtained is shown in Table 1. For twin storage devices: storage device A, since the storage characteristics of storage device A are different from the storage characteristics of all other storage devices, 2 can be set as the distinguishing parameter of storage device C.

[0068] Step S204: When the storage characteristics of any storage device other than storage device γ are the same as those of storage device γ, the storage device with the same storage characteristics as storage device γ is recorded as the anchor device, and the sum of the security device characteristics of storage device γ and the security device characteristics of all anchor devices is recorded as the distinguishing parameter of storage device β. Storage device β may have multiple distinguishing parameters.

[0069] Step S205: Obtain the distinguishing parameters corresponding to all storage devices containing twin storage devices in the identification backup table.

[0070] Step S3: When identifying a storage device, a security screening is performed on the storage device to be identified based on data security, and the storage device is identified based on the distinguishing parameters.

[0071] Step S301, when identifying the storage device, please refer to... Figure 4 As shown, the storage device to be identified is denoted as the device to be identified; the storage characteristics of the device to be identified are obtained by the storage characteristic acquisition method and denoted as the identification storage characteristics; the storage devices in the identification backup table whose storage characteristics are equal to the identification storage characteristics are denoted as the devices to be confirmed.

[0072] Step S302: When the number of devices to be verified is 1: Use data security screening software to perform security screening on the device to be identified, and obtain the security device features of the device to be identified during the security screening based on the security device feature acquisition method; when the security device features of the device to be identified are equal to the security device features of the device to be verified, identify the device to be identified as the device to be verified; when the security device features of the device to be identified are not equal to the security device features of the device to be verified, identify the device to be identified as an unrecorded device.

[0073] In the specific implementation process, when the number of devices to be confirmed is 1, it means that only one recorded storage device has the same storage characteristics as the device to be identified. Therefore, identification can be performed simply by comparing the characteristics of the security devices.

[0074] Step S303: When the number of devices to be confirmed is greater than 1: Use data security screening software to perform security screening on the devices to be identified, and obtain the security device features of the devices to be identified during the security screening based on the security device feature acquisition method; record the sum of the security device features of all devices to be confirmed as the confirmation parameter; when the distinguishing parameter of any device to be confirmed Ω is equal to the storage feature or the confirmation parameter of the device to be identified, the device to be identified is identified as the device to be confirmed Ω.

[0075] Step S304: When the distinguishing parameters of all devices to be identified are not equal to the storage characteristics or the parameters to be identified of the device to be identified, the device to be identified is identified as an unrecorded device.

[0076] Example 2, please refer to Figure 3 As shown, Figure 3A schematic diagram of an electronic device is provided, which may include a processor, a communication interface, a memory, and a communication bus. The processor, communication interface, and memory communicate with each other via the communication bus.
