Description

Technical Field

[0001] The invention belongs to the field of unidirectional transmission breakpoint resumption, and in particular relates to a unidirectional transmission breakpoint resumption device and method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Currently, one-way import is a common security solution for importing sensitive information from low-level to high-level. One-way import usually includes a one-way import device and corresponding PC host software, such as Figure 1 As shown. Due to the one-way physical isolation of the existing one-way import device, the sender cannot obtain any information from the target end (information receiving end). If the transmission fails due to some reason during the file transmission process, the subsequent sender can only restart the transmission task from the beginning, and cannot directly resume the transmission at the wrong file. In this way, when the transmission task is large, the part that has been successfully transmitted for a long time needs to be transmitted again, resulting in a long time for the entire transmission process, a waste of retransmission time, and low overall transmission efficiency. Summary of the invention

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a one-way transmission breakpoint resumption device and method, which can quickly resume the transmission task after the one-way transmission is abnormally interrupted, saving retransmission time.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A first aspect of the present invention provides a one-way transmission breakpoint resume device.

[0009] The human-computer interaction module is used to: input the breakpoint code of the interruption position as a manual instruction to the sending end, so that the sending end continues the transmission task from the transmission interruption position.

[0010] As an implementation mode, the interruption position analysis module is embedded in a host computer.

[0011] As an implementation mode, the process of the interruption position parsing module reading and parsing the data received by the receiving end of the one-way import device is as follows:

[0012] After the file transfer starts, the folder ID combination where the current transferred file is located is recorded;

[0013] When entering and exiting a folder, the ID combination structure is added and deleted accordingly;

[0014] When the host computer is abnormally interrupted in receiving files, a breakpoint code of the interruption position is generated according to the current folder ID combination combined with the package number of the last transmitted file.

[0015] As an implementation mode, the human-computer interaction module includes a first sub-human-computer interaction module and a second sub-human-computer interaction module; the first sub-human-computer interaction module is directly connected to the transmitting end of the one-way import device, and the second sub-human-computer interaction module is connected to the host computer.

[0016] As an implementation manner, the first sub-human-computer interaction module is a first unidirectional transmission device.

[0017] As an implementation manner, the first unidirectional transmission device is a key array.

[0018] As an implementation manner, the second sub-human-computer interaction module is a second unidirectional transmission device.

[0019] As an implementation manner, the second unidirectional transmission device is a voice module or a display module having only a display function.

[0020] A second aspect of the present invention provides a method for breakpoint-resume transmission in one-way transmission.

[0021] Based on the one-way transmission breakpoint resuming device as described above, the one-way transmission breakpoint resuming method includes:

[0022] The interruption position parsing module is used to read and parse the data received by the receiving end of the one-way import device to obtain the file directory of the one-way data transmission from the sending end to the receiving end; and when the upper computer receives the file abnormally interrupted, the breakpoint code of the interruption position is generated according to the file directory and prompted;

[0023] The breakpoint code of the interruption position is input as a manual instruction to the sending end by using a human-computer interaction module, so that the sending end continues the transmission task from the transmission interruption position.

[0024] As an implementation method, the process of using the interruption position analysis module to read and analyze the data received by the receiving end of the one-way import device is as follows:

[0025] After the file transfer starts, the folder ID combination where the current transferred file is located is recorded;

[0026] When entering and exiting a folder, the ID combination structure is added and deleted accordingly;

[0027] When the host computer is abnormally interrupted in receiving files, a breakpoint code of the interruption position is generated according to the current folder ID combination combined with the package number of the last transmitted file.

[0030] Advantages of additional aspects of the present invention will be given in part in the following description, and in part will become obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The accompanying drawings in the specification, which constitute a part of the present invention, are used to provide a further understanding of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute improper limitations on the present invention.

[0032] Figure 1 It is a one-way import schematic.

[0033] Figure 2 It is a schematic diagram of a one-way transmission breakpoint resume device according to an embodiment of the present invention. DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0036] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0037] Terminology explanation:

[0038] Combination Figure 1 One-way import is to parse the content in USB storage media such as U disk and hard disk through the file system, and use the data one-way transmission module to transmit it to a higher density or intranet computer host, and complete the data placement through the host computer software installed in the intranet. Because its hardware often uses a one-way optical fiber module, the unidirectionality of light transmission is used to send the data on the sending side to the receiving side without feedback. The information data flow can only flow from one end to the other end in one direction without feedback. The sending end cannot obtain any information from the target end (information receiving end). While realizing data transmission, the risk of information leakage is also avoided through physical isolation, realizing the functional device of one-way import of data content in the storage medium.

[0039] Due to the particularity of one-way import (all information is not allowed to be directly transmitted to the external network through a certain device or program), data information can only be transmitted in one direction. When a transmission error occurs, the user can only obtain the error but cannot restore the transmission through operation settings. In view of the above problems, the one-way import implemented by the present invention is composed of a one-way import device equipped with a human-computer interaction module and a host computer with a file directory synchronization function.

[0040] Figure 2 The schematic diagram of the one-way transmission breakpoint resume device according to the embodiment of the present invention is given. Figure 2 As shown, a one-way transmission breakpoint resume device according to an embodiment of the present invention comprises: a human-computer interaction module and an interruption position analysis module;

[0041] The interruption position analysis module is used to: read and analyze the data received by the receiving end of the one-way import device to obtain the file directory of the one-way data transmission from the sending end to the receiving end; and when the host computer receives the file abnormally interrupted, generate the breakpoint code of the interruption position according to the file directory and prompt;

[0042] The human-computer interaction module is used to: input the breakpoint code of the interruption position as a manual instruction to the sending end, so that the sending end continues the transmission task from the transmission interruption position.

[0043] In this embodiment, the interruption position analysis module is embedded in the host computer.

[0044] The sending end of the one-way import device of this embodiment will perform file system analysis on the USB storage device after detecting it: when encountering a file, it will calculate the size of the transferred file and divide it into packets according to the corresponding packet number; when encountering a folder, it will assign an ID number to the folder, and can accurately locate a certain package of data of a certain file in combination with the file division (for example, "1-2-3-121", which means the 121st package of data of the third file in the second folder in the first folder in a certain order), and will also send a response instruction when entering and exiting the folder. The above information is transmitted to the receiving end in one direction through the one-way sending module.

[0045] The interruption position analysis module in the host computer obtains the data from the sending end by reading the data from the receiving end. In the specific implementation process, the process of the interruption position analysis module reading and analyzing the data received by the receiving end of the one-way import device is as follows:

[0046] After the file transfer starts, the folder ID combination where the current transferred file is located is recorded;

[0047] When entering and exiting a folder, the ID combination structure is added and deleted accordingly;

[0048] When the host computer is abnormally interrupted in receiving files, a breakpoint code of the interruption position is generated according to the current folder ID combination combined with the package number of the last transmitted file.

[0049] It can be understood here that the interrupt position analysis module reads and analyzes the data received by the receiving end of the one-way import device to synchronously obtain the file directory of the sending data of the sending end, and other existing methods can also be used to achieve it, which will not be described in detail here.

[0050] In one or more embodiments, the human-computer interaction module includes a first sub-human-computer interaction module and a second sub-human-computer interaction module; the first sub-human-computer interaction module is directly connected to the transmitting end of the one-way import device, and the second sub-human-computer interaction module is connected to the host computer.

[0051] Among them, the first sub-human-computer interaction module is a first unidirectional transmission device.

[0052] For example, the first unidirectional transmission device is a key array.

[0053] After the user presses a button, the sender will receive the corresponding key value, just like sending file data, and send the key value unidirectionally to the receiving end. The host computer receives data from the receiving end, and after receiving different key values, it displays the corresponding interface (the interface is passively controlled by the human-computer interaction button). At this time, the human-computer interaction interface of the PC host computer is equivalent to the screen operated by the sender of the one-way import device. The user can visually input the breakpoint code to the sender in this way. The sender can find the corresponding transmission interruption position through the breakpoint code and continue the transmission task from the interruption point.

[0054] It should be noted here that the first unidirectional transmission device may also be a touch screen, and those skilled in the art may make a specific selection according to actual conditions.

[0055] During the screenshot implementation process, the second sub-human-computer interaction module is a second unidirectional transmission device.

[0056] For example, the second unidirectional transmission device is a voice module (which can voice broadcast the breakpoint code of the interruption position) or a display module with only a display function (which can directly display the breakpoint code of the interruption position).

[0057] When the second unidirectional transmission device is a display module, it can be implemented using a display screen of a host computer.

[0058] This embodiment adds a human-computer interaction module to the one-way import device, and adds an interrupt position analysis module to the corresponding host computer, thereby realizing the directory synchronization logic, and further realizing the breakpoint resume function by combining the above two points; after the transmission task is interrupted, there is no need to restart the transmission from the beginning. While ensuring the safety of the user's use environment, the transmission task can be quickly restored, saving retransmission time, and greatly improving the safety of the user's working environment and work efficiency.

[0059] Based on the one-way transmission breakpoint resuming device as described above, the one-way transmission breakpoint resuming method includes:

[0060] Step 1: using the interruption position analysis module to read and analyze the data received by the receiving end of the one-way import device, and obtain the file directory of the one-way data transmission from the sending end to the receiving end; and when the host computer receives the file abnormally interrupted, according to the file directory, generate the breakpoint code of the interruption position and prompt;

[0061] Step 2: using a human-computer interaction module to input the breakpoint code of the interruption position as a manual instruction to the sending end, so that the sending end continues the transmission task from the transmission interruption position.

[0062] Specifically, the process of using the interruption position analysis module to read and analyze the data received by the receiving end of the one-way import device is as follows:

[0063] After the file transfer starts, the folder ID combination where the current transferred file is located is recorded;

[0064] When entering and exiting a folder, the ID combination structure is added and deleted accordingly;

[0065] When the host computer is abnormally interrupted in receiving files, a breakpoint code of the interruption position is generated according to the current folder ID combination combined with the package number of the last transmitted file.

[0066] This embodiment can realize file transfer while ensuring the security of user intranet (high-density environment) data, and has the function of resuming file transfer from breakpoints. After an abnormal interruption of one-way transmission, the transmission task can be quickly restored, saving retransmission time, greatly improving the security of the user's working environment and work efficiency.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
