Description

Technical Field

[0001] The present invention relates to the technical field of device identification, and in particular to a storage device identification method based on data security, an electronic device and a storage medium. Background Art

[0002] Storage device identification refers to the process of computer systems identifying and confirming storage devices, including identification at the hardware level, identification at the operating system level, and identification at the device management software level; identification at the hardware level means that the chipset and BIOS on the server motherboard are responsible for identifying and managing storage devices; identification at the operating system level means that once the hardware level identification is completed, the server's operating system will further identify and manage the storage device; identification at the device management software level means that in some large server environments, storage devices are further identified and managed through device management software.

[0003] Existing improvements in storage device identification are usually used to solve the identification method of storage devices in multiple access states, such as storing the identification information of the target storage device in the shortcut, and comparing the representation information of the connected storage device with the identification information stored in the shortcut, so as to identify the storage device. Although this improved method can effectively identify the storage device in multiple access states of the storage device, the identification method can only compare and identify through the identification information, and when performing device identification, a shortcut needs to be established and the identification information needs to be stored in the shortcut. The identification method is relatively complicated, resulting in the problem of slow identification efficiency and low identification security. For example, in the patent application No. CN111198830A, The patent application discloses a method, apparatus, electronic device and storage medium for identifying a mobile storage device. The solution is to receive an operation that triggers a shortcut icon so that when the access status of the target mobile storage device changes, the target mobile storage device can still be identified, so that the shortcut icon can be used normally. Other improvements for storage device identification usually obtain the corresponding identification code based on the basic information of the storage device and perform corresponding identification. This improved method still has the problem that the identification method is relatively simple and the identification code corresponding to the storage device is easy to be cracked, resulting in security risks in the identification process and low identification security. In view of this, it is necessary to improve the existing storage device identification method. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0044] Step S1, security screening is performed on the existing data in the storage device, and security device characteristics are obtained during the security screening; the storage device is pre-identified based on the security device characteristics, and storage characteristics of the security device are obtained based on the pre-identification results;

[0045] Step S1 includes: Step S101, recording the storage hard disks in the storage device as device hard disk SY1 to device hard disk SY n ; Obtain existing data security screening software, and use the data security screening software to screen the device hard disk SY1 to the device hard disk SY n Perform security screening; for any device hard disk SY c , SY the device hard disk c The capacity of the device hard disk is recorded as the total capacity of the hard disk. c The capacity occupied by the data in the disk is recorded as the total data capacity, and the value of the total data capacity divided by the total hard disk capacity is recorded as the data ratio;

[0046] In the specific implementation process, in the actual process of obtaining the device hard disk SY, it can be obtained according to the independent hard disk in the storage device. For example, the hard disk in the storage device may include a mechanical hard disk, a solid-state hard disk, a hybrid hard disk and a network hard disk; then the mutually opposed mechanical hard disk and solid-state hard disk can be respectively recorded as two device hard disks SY;

[0047] Step S102, establish a plane rectangular coordinate system, recorded as the screening analysis coordinate system, wherein the unit of the X-axis of the screening analysis coordinate system is time, and the Y-axis is the number axis and the corresponding value is G0 is the data security screening software for the device hard disk SY c When conducting security screening, the ratio of the amount of data screened to the total data capacity, G1 is the data ratio;

[0048] In the specific implementation process, for example, in a data processing, the total data capacity corresponding to a device hard disk SY is 100T, and the total hard disk capacity is 200T. Then, through calculation, it can be obtained that the data ratio is 0.5; at the same time, the screening curve SQ is obtained 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 obtained by connecting point MI and point MA does not intersect with the screening curve SQ, that is, the screening fluctuation point number is 0, and the fluctuation feature algorithm cannot be calculated at this time. Therefore, in this embodiment, when the screening fluctuation point number is 0, the secure hard disk feature is set to 0;

[0049] Step S103, when the data security screening software starts to SY the device hard disk c After data screening, draw the corresponding curve in the screening analysis coordinate system based on real-time data until the device hard disk SY c After the screening is completed, the obtained curve is recorded as the screening curve SQ c ;

[0050] Step S104: Screening curve SQ c The highest point and the lowest point in the slope are recorded as the fastest screening point and the slowest screening point respectively. Connect the fastest screening point and the slowest screening point, and connect the connecting line with the screening curve SQ c The intersection of is recorded as the screening fluctuation point, and the number of screening fluctuation points is recorded as the number of screening fluctuation points; the fluctuation feature algorithm is used to obtain the device hard disk SY c The corresponding secure hard disk feature and fluctuation feature algorithm are: Among them, F1 is the safe hard disk feature, m is the screening fluctuation point, and f i is the slope corresponding to the i-th screening fluctuation point, X i is the horizontal coordinate of the i-th screening fluctuation point;

[0051] For example, in one data processing, the number of screening fluctuation points obtained is 1, and the coordinates of the screening fluctuation points are (20, 3), and the slope of the screening fluctuation points is 2, then the number of screening fluctuation points is 1, and the security hard disk feature can be obtained by calculation as 2 / 3; by obtaining the security hard disk feature, the feature corresponding to each device hard disk can be obtained based on the speed at which each device hard disk is securely screened, thereby ensuring that the obtained security device feature can match the status of all device hard disks in the security device feature;

[0052] Step S105, obtain all device hard disk SY c The corresponding secure hard disk features are obtained by using the hard disk comprehensive algorithm to obtain the secure device features of the storage device. The disk comprehensive algorithm is: Among them, F2 is the safety device feature, H j is the secure hard disk feature of the j-th device hard disk SY, is the average value of the secure hard disk characteristics of all device hard disks SY;

[0053] In the specific implementation process, for example, in a data processing, the secure hard disk characteristics of all device hard disks of the device are 0.5, 1, 1, 0.5 and 2 respectively, then the calculation can be obtained is 1, and F2 is 0.3; therefore, the security device characteristic of the storage device can be set to 0.3;

[0054] Step S106, obtaining and recording the security device characteristics of all identifiable storage devices; setting the pre-identification standard of the recorded storage device as the security device characteristic corresponding to the storage device;

[0055] Step S107, for any recorded storage device: input data α to all device hard disks SY of the storage device at the same time, and record the average value of the instantaneous read / write rates of all device hard disks SY when data input starts as the input storage average value; after data α is input to all device hard disks SY, record the average value of the time for all device hard disks SY to input data α as the input time average value, and all device hard disks SY output data α;

[0056] Step S108, record the average value of the instantaneous read and write rates of all device hard disks SY when data output starts as the output storage average value, and after data α is output by all device hard disks SY, record the average value of the time for all device hard disks to output data α as the output time average value, and Denoted as the storage characteristics of the storage device, where t1 is the input time mean, t2 is the output time mean, v1 is the input storage mean, and v2 is the output storage mean;

[0057] In the specific implementation process, data α is only used to obtain storage characteristics. Data α can be set according to actual conditions. At the same time, it should be ensured that when the storage characteristics of the storage device are subsequently obtained, the data for data input and data output are all data α; for example, in the process of obtaining storage characteristics once, the input storage average is 2mb / s, the output storage average is 4mb / s, the input time average is 20s, and the output time average is 10s. Then, by calculation, the storage characteristic of the storage device can be obtained as 1.5;

[0058] Step S109, obtaining storage characteristics corresponding to all recorded storage devices.

[0059] Step S2: Use the security device features and storage features to identify and back up the storage device, and obtain the twin storage device based on the backup result; 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 result;

[0060] Step S2 includes: Step S201, establishing a table of R rows×3 columns, recorded as an identification backup table, wherein the top row of the identification backup table except the first cell is filled with security device features and storage features in sequence, and the leftmost column except 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 the storage device γ, the storage device γ is recorded as the twin storage device of the storage device β;

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

[0064] Safety equipment features 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 obtaining twin storage devices is to effectively distinguish storage devices with the same security device characteristics, so as to prevent the problem of identification errors caused by the same security device characteristics during identification;

[0066] Step S203, performing a difference analysis process on the storage device γ; the difference analysis process is: when the storage characteristics of the storage device γ are different from the storage characteristics of all storage devices except the storage device γ, the storage characteristics of the storage device γ are recorded as the distinguishing parameters of the 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 the 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 the storage device γ are the same as the storage characteristics of the storage device γ, the storage device having the same storage characteristics as the storage device γ is recorded as an anchor device, and the sum of the security device characteristics of the storage device γ and the security device characteristics of all anchor devices is recorded as a distinguishing parameter of the storage device β, where the storage device β may have multiple distinguishing parameters;

[0069] Step S205, obtaining 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, 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, refer to Figure 4 As shown, the storage device to be identified is recorded as the device to be identified; the storage characteristics of the device to be identified are obtained based on the storage characteristic acquisition method, and recorded as the identification storage characteristics; the storage device whose storage characteristics in the identification backup table are equal to the identification storage characteristics is recorded as the device to be confirmed;

[0072] Step S302, when the number of devices to be confirmed is 1: use data security screening software to perform security screening on the devices to be identified, and obtain security device features of the devices to be identified during the security screening based on the method for obtaining security device features; when the security device features of the devices to be identified are equal to the security device features of the devices to be confirmed, identify the devices to be identified as devices to be confirmed; when the security device features of the devices to be identified are not equal to the security device features of the devices to be confirmed, identify the devices to be identified as unrecorded devices;

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

[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 security device features of the devices to be identified during the security screening based on the method for obtaining security device features; the sum of the security device features of all devices to be confirmed is recorded as the parameter to be confirmed; when the distinguishing parameter of any device to be confirmed Ω is equal to the stored feature or the parameter to be confirmed 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 the devices to be confirmed are not equal to the stored features or the parameters to be confirmed of the device to be identified, the device to be identified is identified as an unrecorded device.
