[0002] With the continuous development of computer storage technology, the capacity and ease of use of portable storage media have been greatly improved, making them frequently used devices in daily office work. However, while bringing convenience to work, portable storage media also pose significant security risks to enterprises. In existing technologies, when portable storage media (such as USB flash drives, portable hard drives, floppy disks, optical discs, and memory cards) are connected to a terminal, the terminal operating system automatically mounts the portable storage media without authenticating or authorizing it. Therefore, portable storage media can easily become carriers of viruses and can also cause data leaks within enterprises. Thus, how to more effectively manage the use of portable storage media to prevent virus spread and data leaks has become a pressing technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0037] Example 1

[0038] This invention provides a method for managing and controlling mobile storage media, such as... Figure 1 As shown, the method specifically includes the following steps:

[0039] Step S101: When the removable storage medium is detected to be connected to the Linux system, the formatted normal partition in the removable storage medium is mounted to the Linux system, wherein the removable storage medium includes: a formatted normal partition and an unformatted physical disk block device.

[0040] It should be noted that this embodiment is applicable to Linux systems, and can be used to manage the use of removable storage media in Linux systems.

[0041] Because there is only a single file structure tree in the Linux system, and the root directory of this file structure tree is / , all accessible files must be associated with this file structure tree. Therefore, if the Linux system needs to use an external device, it needs to associate the file system of the external device with the file structure tree. The act of mounting is to associate the external device with the file structure tree of the Linux system so that the Linux system can find the associated external device starting from the root directory and thus access the file data within the external device.

[0042] Specifically, the method further includes:

[0043] Step A1: Select a portion of the storage area from the removable storage medium to perform a partitioning operation to obtain the normal partition, and use the unselected storage area in the removable storage medium as the physical disk block device, wherein the storage space size of the normal partition is smaller than the storage space size of the physical disk block device;

[0044] Among them, such as Figure 2 The diagram shows the physical disk data layout of a removable storage medium. Normal partitions occupy only a small portion of the storage space on the removable storage medium.

[0045] Step A2: Format the normal partition and store the preset control program in the formatted normal partition;

[0046] The control program is used to authenticate the user using the mobile storage medium and, after successful authentication, allow the user to read and write to the unformatted storage area of ​​the mobile storage medium through the loop device in the Linux system.

[0047] Step A3: Store the preset registration information in the formatted normal partition; wherein, the registration information includes: verification information used for identity verification;

[0048] The verification information includes: device identification information (device ID) for uniquely identifying the removable storage medium, user identification information (user ID) for uniquely identifying the user, password information, and user access permission information for the removable storage medium (e.g., read / write, read-only, disabled).

[0049] When using removable storage media (e.g., USB flash drives, optical discs, hard drives, floppy disks), the media must first be partitioned and formatted. The Linux system can only mount the formatted storage area of ​​the removable storage media, storing authentication information in the formatted partition. Only after successful authentication and security confirmation is the Linux system allowed to read and write to the unformatted storage area of ​​the removable storage media, thus improving security during access. In this embodiment, the removable storage media is pre-partitioned and formatted using a special format to obtain a normal partition occupying only a minimal amount of storage space and an unpartitioned, unformatted storage area occupying the vast majority of storage space. Pre-set control programs and registration information are stored in the normal partition. By setting the storage space of the formatted normal partition to be a very small proportion of the total storage space of the removable storage media, security is improved without significantly affecting the media's normal storage functions.

[0050] In practical applications, a pre-set processing program can be used to implement steps A1 to A3 above. This program processes removable storage media in batches, ensuring that each processed removable storage media contains a normal partition with management programs and registration information stored within it. When a processed removable storage media is connected to a target terminal with a Linux system, the normal partition can be directly mounted to the target terminal, allowing the target terminal to read the management programs and registration information from the normal partition. Alternatively, the processing program can be stored in a target terminal with a Linux system. When an unused removable storage media is connected to the target terminal, the processing program is invoked to create a normal partition on the removable storage media, and the management programs and registration information are stored in the normal partition. Then, the normal partition is directly mounted to the target terminal.

[0051] Step S102: Obtain the pre-stored management program from the normal partition through the Linux system.

[0052] In this embodiment, since only the normal partition in the removable storage medium has been formatted, the Linux system can read the contents of the normal partition normally.

[0053] Step S103: Invoke the management program to authenticate the removable storage medium, and after successful authentication, access the unformatted physical disk block device in the removable storage medium through the loop device in the Linux system.

[0054] Specifically, the step of invoking the control program to authenticate the removable storage medium includes:

[0055] Step B1: Invoke the control program to obtain the authentication information entered by the user through the Linux system;

[0056] Step B2: Determine whether the verification information entered by the user is consistent with the verification information in the registration information;

[0057] Step B3: If yes, authentication is successful; otherwise, the normal partition is unloaded from the Linux system.

[0058] In this embodiment, when the control program is invoked, it displays a dialog box on the target terminal for the user to input verification information, such as user ID and password. The control program determines whether the user ID and password entered by the user are consistent with the user ID and password in the registration information. If they are, the authentication is successful and the user can use the removable storage medium normally. If not, the authentication fails and a security prompt message is displayed on the target terminal.

[0059] In practical applications, a corresponding mobile storage medium can be configured for each employee in the company, that is, the mobile storage medium stores only the unique employee ID information; or a corresponding mobile storage medium can be configured for each part of the company, that is, the mobile storage medium stores the ID information of all employees in that part.

[0060] Furthermore, the step of selecting a portion of the storage area from the removable storage medium to perform a partitioning operation to obtain the normal partition, and using the unselected storage area in the removable storage medium as the physical disk block device, specifically includes:

[0061] Step C1: Write the start and end address information of the normal partition into the partition table set in the removable storage medium;

[0062] Step C2: Based on the storage space size of the removable storage medium and the start and end address information of the normal partition stored in the partition table, determine the unpartitioned storage area in the removable storage medium, and set the unpartitioned storage area as the physical disk block device.

[0063] like Figure 2As shown, a partition table is set up in the removable storage medium. This partition table records the storage space size information of the removable storage medium and the start and end address information of each partition. The unpartitioned storage area in the removable storage medium can be determined through this partition table, and the unpartitioned storage area exists in the form of physical disk block devices.

[0064] Furthermore, the step of accessing the unformatted physical disk block device in the removable storage medium via the loop device in the Linux system after successful authentication specifically includes:

[0065] The management program is invoked to identify an idle target loop device from the Linux system, the physical disk block device is associated with the target loop device, and the target loop device is mounted to the Linux system so that the Linux system can perform read and write operations on the physical disk block device.

[0066] A loop device is a pseudo-device, also known as a loopback device, that can be used to simulate a file as a block device. Once a file is simulated as a block device, it can be used like a disk or optical disc. Typically, a Linux system has eight loop devices, usually / dev / loop0 to / dev / loop7. You can use the `losetup -a` command to check the usage of all loop devices. If the command outputs nothing, it means that none of the loop devices are currently in use, and these unused loop devices can be used for storage.

[0067] Furthermore, the invocation of the management program to determine the idle target loop device from the Linux system specifically includes:

[0068] Obtain the device IDs of all loop devices in the Linux system;

[0069] The usage status of each loop device is queried sequentially in ascending order of device number until an idle loop device is found, and the idle loop device is selected as the target loop device.

[0070] In practical applications, there are usually 8 loop devices in a Linux system, typically / dev / loop0 to / dev / loop7. In this embodiment, based on the loop device's code, the usage status of each loop device is queried in ascending order of its number, and the first loop device with an idle usage status is set as the target loop device. That is, when there are multiple loop devices, only the loop device with the smallest number and an idle usage status is set as the target loop device.

[0071] Associating the physical disk block device with the target loop device specifically includes:

[0072] The physical disk block device is associated with the target loop device using the losetup command;

[0073] For example, `losetup / dev / loop3 a.ios` associates the physical disk block device `a.ios` with the fourth loop device in the Linux system using the `losetup` command.

[0074] The step of mounting the target loop device to the Linux system specifically includes:

[0075] Create an empty subdirectory under the root directory / of the Linux system, and mount the target loop device to the empty subdirectory using the mount command.

[0076] Since mounting will hide files in existing subdirectories, the root directory and existing subdirectories of the Linux system are not suitable as mount points. Empty subdirectories need to be created as mount points. When the target loop device is mounted to an empty subdirectory, when a user accesses the empty subdirectory through the Linux system, it is equivalent to accessing the physical disk block device in the removable storage medium managed by the target loop device. This enables the Linux system to read and write to the unpartitioned storage area in the removable storage medium.

[0077] In the prior art, the loop device in the Linux system can simulate a file as a block device, and the Linux system can perform read and write operations on the file by associating the block device with the loop device and mounting the loop device to the Linux system. The unpartitioned storage area in the removable storage medium is equivalent to a block device. Therefore, in this embodiment, the read and write operations of the unpartitioned storage area in the removable storage medium can be controlled by using the loop device in the Linux system.

[0078] In this embodiment, the removable storage medium connected to the Linux system is first partitioned and formatted using a special format to obtain a normal partition that occupies only a very small amount of storage space and an unpartitioned storage area that occupies the vast majority of storage space. The unpartitioned storage area exists in the form of a physical disk block device. Then, a preset management program is imported into the normal partition. Finally, after the normal partition is mounted to the Linux system, the management program is called to verify the removable storage medium. After successful verification, the management program is called and the loop device in the Linux system is used to mount the unpartitioned physical disk block device in the removable storage medium to the Linux system, thereby enabling the Linux system to perform read and write operations on the unpartitioned physical disk block device in the removable storage medium.

[0079] Example 2

[0080] This invention provides a method for managing removable storage media, applied to a target terminal using a Linux system. The method specifically includes the following steps:

[0081] Step 1: When the removable storage medium is detected to be connected to the Linux system, perform a partitioning operation on the removable storage medium to obtain normal partitions;

[0082] Among them, such as Figure 2 The diagram shows the physical disk data layout of a removable storage medium. Normal partitions occupy only a small portion of the storage space on the removable storage medium.

[0083] Step 2: Format the normal partition and store the preset control program in the formatted normal partition;

[0084] The control program is used to authenticate the user using the removable storage medium and, after successful authentication, to allow the user to read and write to the unpartitioned storage area of ​​the removable storage medium through the loop device in the Linux system.

[0085] Step 3: Store the preset registration information in the formatted normal partition; wherein, the registration information includes: verification information used for identity verification;

[0086] The verification information includes: device identification information (device ID) for uniquely identifying the removable storage medium, user identification information (user ID) for uniquely identifying the user, password information, and user access permission information for the removable storage medium (e.g., read / write, read-only).

[0087] Step 4: Write the start and end address information of the normal partition into the partition table set in the removable storage medium.

[0088] Step 5: Based on the storage space size of the removable storage medium and the start and end address information of the normal partition stored in the partition table, determine the unpartitioned storage area in the removable storage medium and set the unpartitioned storage area as a physical disk block device;

[0089] like Figure 2 As shown, a partition table is set up in the removable storage medium. This partition table records the storage space size information of the removable storage medium and the start and end address information of each partition. The unpartitioned storage area in the removable storage medium can be determined through this partition table, and the unpartitioned storage area exists in the form of physical disk block devices.

[0090] Step 6: Mount the formatted normal partition in the removable storage medium to the Linux system.

[0091] Step 7: Call the management program in the normal partition to obtain the verification information entered by the user through the Linux system.

[0092] In this embodiment, when the control program is invoked, it displays a dialog box on the target terminal for the user to input verification information, such as user ID and password. The control program determines whether the user ID and password entered by the user are consistent with the user ID and password in the registration information. If they are, the authentication is successful and the user can use the removable storage medium normally. If not, the authentication fails and a security prompt message is displayed on the target terminal.

[0093] Step 8: Determine whether the verification information entered by the user matches the verification information in the registration information; if yes, the authentication is successful and proceed to step 9; if no, the authentication fails and the normal partition is unloaded from the Linux system.

[0094] Step 9: Call the control program to query the usage status of each loop device in ascending order of the device number, and set the first loop device with an idle usage status as the target loop device.

[0095] Step 10: Invoke the management program to associate the physical disk block device with the target loop device via the losetup command.

[0096] Step 11: Invoke the management program to mount the target loop device to the Linux system, so as to enable the Linux system to read and write to the physical disk block device.
