[0047] As described above, the digital textbook data currently stored in the USB flash drive is easily copied and disseminated without permission, which makes it difficult to effectively protect the copyright security of the digital textbook data. Based on this, it is necessary to provide a more secure digital textbook data protection method to effectively protect the copyright security of the digital textbook data in the USB flash drive.

[0048] After research, the inventor proposed a digital textbook data protection method based on a USB flash drive, which receives a startup operation instruction from a digital textbook client; wherein the digital textbook client is located in the read-write operation partition of the target USB flash drive, and the startup operation instruction carries the unique identification information of the digital textbook corresponding to the digital textbook client, as well as the path information of the target folder, the target folder is located in the solidified partition of the target USB flash drive, and the target folder contains a key file, which is used to verify whether the digital textbook client has the startup permission; then, after verifying the existence of the target folder based on the path information, the key file in the target folder is obtained; finally, if the identification information in the key file matches the unique identification information of the digital textbook, it is determined that the digital textbook client has the startup permission, and the digital textbook client is allowed to read the digital textbook data from the read-write operation partition.

[0049] In the technical solution of the present application, a key file used to verify whether the digital textbook client has the startup permission is stored in a target folder of the solidified partition of the target U disk, and the digital textbook client is stored in the read-write operation partition of the target U disk. When receiving the startup operation instruction of the digital textbook client, the key file in the target folder is obtained only when the existence of the target folder is verified based on the path information, and when the identification information in the key file matches the unique identification information of the digital textbook, it is determined that the digital textbook client has the startup permission, and the digital textbook client is allowed to read the digital textbook data from the read-write operation partition, thereby avoiding the problem of low security of the digital textbook data due to the digital textbook data in the target U disk being copied to other storage media without permission, improving the security of the digital textbook data, and effectively protecting the copyright security of the digital textbook data.

[0052] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] Method Embodiment

[0054] The embodiment of the present application provides an embodiment of a digital teaching material data protection method based on a USB flash drive. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0055] See also Figure 1 , which is a flow chart of a digital teaching material data protection method based on a USB flash drive provided in an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0056] Step S101, receiving a start-up operation instruction from a digital textbook client; the start-up operation instruction carries unique identification information of the digital textbook corresponding to the digital textbook client, and path information of a target folder.

[0057] In an optional embodiment, a digital teaching material data protection system based on a USB disk can be used as the execution subject of the digital teaching material data protection method based on a USB disk of the embodiment of the present application. For the convenience of description, the digital teaching material data protection system based on a USB disk is referred to as a system below.

[0058] In step S101, the digital textbook client is located in the read-write operation partition of the target U disk, and the startup operation instruction carries the unique identification information of the digital textbook corresponding to the digital textbook client and the path information of the target folder. The target folder is located in the solidified partition of the target U disk, and the target folder contains a key file, which is used to verify whether the digital textbook client has the startup permission. When the digital textbook client has the startup permission, the digital textbook client can be started normally; when the digital textbook client does not have the startup permission, the digital textbook client is prohibited from starting.

[0059] In the embodiment of the present application, the digital textbook client is a software application for accessing and managing digital textbook data. The unique identification information of the digital textbook can be a set of codes that uniquely identify and distinguish digital textbook resources, such as ISBN (International Standard Book Number).

[0060] In an embodiment of the present application, the data storage of the target U disk can be divided into two partitions: a read-write operation partition and a solidified partition, wherein the solidified partition can be a solidified CD-ROM, and the data stored in the solidified partition (such as the key file) is invisible and cannot be tampered with, and the data stored in the read-write operation partition (such as the digital teaching material data) can be read and written normally; therefore, when the data in the target U disk is copied to other storage media without permission, the key file located in the target folder of the solidified partition cannot be copied, thereby improving the security and stability of the key file, and providing a basis for the subsequent digital teaching material client to safely start and read the digital teaching material data.

[0061] In an embodiment of the present application, the target folder is a specific folder pre-set in a solidified partition of the target USB flash drive, which is used to store a key file for verifying whether the digital teaching material client has the startup permission.

[0062] In order to enable the digital textbook client to start safely and read the digital textbook data, in the embodiment of the present application, before receiving the start-up operation instruction of the digital textbook client, such as Figure 2 As shown, the system can generate a key file based on the unique identification information of the digital textbook and write the key file into the fixed partition of the target USB flash drive. Figure 3 , Figure 3 A flowchart of a process of writing a key file into a hardened partition provided in an embodiment of the present application, the process comprising the following steps:

[0063] Step S301, obtaining the unique identification information of the digital teaching material and the path information of the target folder.

[0064] Step S302: Generate a key file based on the unique identification information.

[0065] In order to ensure the uniqueness and confidentiality of the key file, in an embodiment of the present application, the system can generate a key file based on preset security standards and unique identification information of the digital textbook, thereby providing a data basis for the data protection mechanism of the digital textbook based on the target USB flash drive.

[0066] Step S303: Write the key file into the fixed partition of the target USB flash drive based on the path information.

[0067] In this embodiment, the system can generate a solidified partition on the target U disk and write the key file to the solidified partition of the target U disk based on the path information of the target folder, thereby achieving a close integration of the hardware of the target U disk and the data protection mechanism of the digital textbook, thereby improving the security of the digital textbook data.

[0068] In order to further enable the digital textbook client to achieve secure startup and read digital textbook data, in the embodiment of the present application, before receiving the startup operation instruction of the digital textbook client, such as Figure 2 As shown, the system can write the encrypted digital teaching material resources into the read-write operation partition of the target USB flash drive. Figure 4 , Figure 4 A flowchart of a process of writing a digital teaching material resource into a read-write operation partition provided in an embodiment of the present application, the process comprising the following steps:

[0069] Step S401, obtaining digital teaching material resources.

[0070] In step S401, the digital teaching material resources include digital teaching material data and the running program of the digital teaching material client, wherein the digital teaching material data includes but is not limited to text courseware (e.g., teaching materials in the form of PPT presentations, HTML pages, etc.), audio and video courseware (e.g., course videos, experimental demonstrations, animation explanations), etc.

[0071] Step S402, classifying the digital teaching material resources according to preset classification rules to obtain classified digital teaching material resources.

[0072] In this embodiment, the preset classification rules are pre-set rules for classifying and storing different types of resource files (e.g., image, audio, video, document, and other resource files) into designated folders. For example, classification by file type, classification by functional module, classification by usage scenario, and classification by version number, etc. The system can classify and store digital teaching materials into corresponding folders based on the preset classification rules to obtain classified digital teaching materials.

[0073] Step S403, encrypting the classified digital teaching material resources with a key to obtain encrypted digital teaching material resources.

[0074] In order to ensure the security and integrity of the digital teaching materials resources in the target USB flash drive, thereby effectively preventing the digital teaching materials resources from being tampered with and unauthorized copying, in an embodiment of the present application, the system may encrypt the digital teaching materials resources based on a preset key to obtain an encrypted digital teaching materials resource. For example, the system may symmetrically encrypt or asymmetrically encrypt the digital teaching materials resources based on a preset key to obtain an encrypted digital teaching materials resource.

[0075] Step S404, writing the encrypted digital teaching material resources into the read-write operation partition of the target USB flash drive.

[0076] In an embodiment of the present application, the system may write the encrypted digital teaching material resources into the read-write operation partition of the target USB flash drive to ensure that the digital teaching material resources can be normally operated and accessed in an authorized environment.

[0077] Step S102: When the existence of the target folder is verified based on the path information, the key file in the target folder is obtained.

[0078] In order to improve the security of digital teaching material data and thus effectively protect the copyright security of digital teaching material data, in the embodiment of the present application, Figure 2 As shown, the system can verify whether the target folder exists based on the path information of the target folder to preliminarily verify whether the digital textbook client has the startup permission; if the target folder exists, the system can directly obtain the key file in the target folder to provide a data basis for further verification of whether the digital textbook client has the startup permission; if the target folder does not exist, the system can determine that the digital textbook client does not have the startup permission, directly prohibit the digital textbook client from reading the digital textbook data, and exit the digital textbook client.

[0079] For example, the digital textbook data in USB drive A is copied to USB drive B without authorization. When the digital textbook client is started in USB drive B, the system can verify whether the target folder exists based on the path information of the target folder. Since the target folder is located in the solidified partition of USB drive A, the target folder cannot be copied when the digital textbook data is copied to USB drive B without authorization. At this time, if the system does not find the target folder in USB drive B, it can be determined that the digital textbook client does not have startup permission, and the digital textbook client is prohibited from reading the digital textbook data, and the digital textbook client is directly exited.

[0080] Step S103: If the identification information in the key file matches the unique identification information of the digital textbook, it is determined that the digital textbook client has the startup permission, and the digital textbook client is allowed to read the digital textbook data from the read-write operation partition.

[0081] In order to further improve the security of digital teaching material data, thereby effectively protecting the copyright security of digital teaching material data, in the embodiment of the present application, Figure 2 As shown, the system can determine whether the digital textbook client has the startup permission by judging whether the identification information in the key file matches the unique identification information of the digital textbook; if the identification information in the key file matches the unique identification information of the digital textbook, it is determined that the digital textbook client has the startup permission, controls the startup of the digital textbook client, and allows the digital textbook client to read the digital textbook data from the read-write operation partition; if the identification information in the key file does not match the unique identification information of the digital textbook, the system can determine that the digital textbook client does not have the startup permission, prohibits the digital textbook client from reading the digital textbook data, and directly exits the digital textbook client.

[0082] For example, the digital textbook data in USB flash drive A is copied to USB flash drive D without authorization. USB flash drive D is provided with a target folder created based on the path information of the target folder and a key file 1. When the digital textbook client is started in USB flash drive D, after verifying the existence of the target folder based on the path information, it obtains the key file 1, and then the system matches the content in the key file 1 with the unique identification information of the digital textbook. Since the content in the key file 1 is unauthorized, the content in the key file 1 is not the same as the content in the key file 1 in the solidified partition of USB flash drive A. Therefore, the system can determine that the identification information in the key file 1 does not match the unique identification information of the digital textbook, and determines that the digital textbook client does not have the startup permission, prohibits the digital textbook client from reading the digital textbook data, and directly exits the digital textbook client.

[0083] Through the U disk-based digital textbook data protection method provided in the embodiment of the present application, a key file used to verify whether a digital textbook client has startup permission is stored in a target folder of a solidified partition of a target U disk, and the digital textbook client is stored in a read-write operation partition of the target U disk. When a startup operation instruction of the digital textbook client is received, the key file in the target folder is obtained only when the existence of the target folder is verified based on the path information, and when the identification information in the key file matches the unique identification information of the digital textbook, it is determined that the digital textbook client has startup permission, and the digital textbook client is allowed to read the digital textbook data from the read-write operation partition, thereby avoiding the problem of low security of the digital textbook data due to the digital textbook data in the target U disk being copied to other storage media without permission, thereby improving the security of the digital textbook data and effectively protecting the copyright security of the digital textbook data.
