Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In some scenarios, data analysis may be required for data running in a secure environment, at which point the data needs to be exported from the secure environment. In the related art, data is generally photographed, exported in the form of a photograph, or a network security officer performs a data transmission operation. However, these methods are cumbersome to operate, and require a lot of time, resulting in low data transmission efficiency.
Based on the foregoing, embodiments of the present invention provide a data processing method and apparatus, and an electronic device, where the technology may be applied to various scenarios requiring data export, data transmission, or data transceiving, and particularly may be applied to data transmission between networks or devices that are isolated from each other.
First, referring to a flowchart of a data processing method shown in fig. 1, the method is applied to a first device; the first device can be a server, a computer or various terminal devices; the method comprises the following steps:
step S102, generating an image group corresponding to data to be transmitted; wherein the group of pictures comprises at least one graphical coded picture; the data to be transmitted is contained in the image group;
the data to be transmitted may be predetermined. The purpose of the data processing method in this embodiment is to transmit data in the first device to the second device, but there is no communication connection in any form between the first device and the second device, and in this scenario, the data to be transmitted may be negotiated and determined in advance through other devices or other manners except the first device and the second device. For example, the data to be transmitted is determined by communicating with devices such as a mobile phone and a computer except the first device and the second device, or by direct communication between workers. After the data to be transmitted is determined, the person with the operation authority can search and select the data to be transmitted from the first device, and then the step S102 is executed.
The data to be transmitted here may be data in any format, for example, text, tables, images, audio, and the like. The graphics code image usually includes a specific shape or a specific color, and the data is stored through the transformation of the shape and the color. For example, the particular shape may be a bar, rectangle, square, circle, or the like; the specific color may be black, white, etc.
The data to be transmitted is usually completely contained in the image group; each graphical encoded image includes at least a portion of the data to be transmitted. When the size of the graphic code image is relatively fixed, the amount of data that can be stored per graphic code image is also relatively fixed. If the data volume of the data to be transmitted is smaller than or equal to the data volume which can be stored in one image coding image, the image group corresponding to the data to be transmitted usually comprises one image coding image, and the image coding image comprises all data of the data to be transmitted.
If the data volume of the data to be transmitted is larger than the data volume which can be stored by one image coding image, the image group corresponding to the data to be transmitted generally comprises a plurality of image coding images, each image coding image comprises a part of data of the data to be transmitted, and the data included by all the image coding images in the image group can form complete data to be transmitted.
Step S104, converting the image group into a file with a specified format; wherein the file with the specified format is used for: when the file with the specified format is opened, the images in the image group are automatically switched and displayed;
the image group comprises at least one image coding image which is relatively separated, and each image coding image can be understood as a single file which can be a file in any image format. In the above steps, the image group is converted into a file with a specified format, and specifically, at least one image coding image included in the image group is integrally converted into one file. This step can also be expressed as generating a specified format file based on the image group.
The file format of the file with the specified format can be preset, and the file format of the file with the specified format needs to have a specific function, namely when the file with the specified format is opened, the images in the image group are automatically switched and displayed, so that after the file with the specified format is opened, the manual operation switching by a user is not needed; especially, when the data volume of the data to be transmitted is large and the generated graphic coding images are more, the function of automatically switching the display images can avoid the labor cost and the time cost caused by manual operation switching, meanwhile, the efficiency of data transmission can be greatly improved, and efficient and rapid large-data-volume data transmission is realized.
Based on the function of automatically switching and displaying images, the file with the specified format can be a video format file, or a dynamic image format file, or can be other files with the specified format or custom formats with the function.
The video format file can be understood as converting the images in the image group into video frames, and when the video format file is opened, the video frames are automatically played, so that the function of automatically switching and displaying the images in the image group is realized. The video format file may specifically be a format file such as mp4, mpeg, avi, mv, and the like. When a video format file is started, a video playing program is usually needed to realize the video format file; the video format file is generally suitable for the situation that the number of images in the image group is large, and each image coded image can be played frame by frame stably.
The above-mentioned moving picture format file may be understood as an image file in which a plurality of graphic coded images are stored together and displayed on a screen one by one, thereby forming a simple animation. When the dynamic image format file is opened, the images in the image group are displayed one by one, so that the function of automatically switching and displaying the images in the image group is realized. The moving image format file may be a gif format file. The dynamic image format file can be opened by using a browser or various application programs, is generally suitable for the situation that the number of images in an image group is small, and is more flexible and convenient to play.
And step S106, opening the file with the specified format.
And starting the file with the specified format, and recording the images in the image group through the second equipment or the third equipment in the process of automatically switching and displaying the images in the image group by the file with the specified format to obtain a recording file of the image group. The second device in this embodiment is a target device to which data to be transmitted needs to be transmitted, and the second device may record a file with a specified format in person to obtain a recorded file, and then process the recorded file to obtain the data to be transmitted. The third device may be understood as an intermediate device between the first device and the second device, where the third device records the file with the specified format to obtain a recorded file, then establishes a communication connection with the second device, sends the recorded file to the second device, and the second device processes the recorded file to obtain data to be transmitted.
In order to realize the transmission of the data to be transmitted, the embodiment is not realized by a mode of transmitting the file with the specified format, but the file with the specified format is opened on the first device, and because the file with the specified format has a function of automatically switching and displaying the images in the image group when the file with the specified format is opened, the images in the image group can be automatically switched and displayed on the screen after the file with the specified format is opened. At this time, the images in the image group displayed in the screen are recorded by the third device, and the recording file of the image group is obtained. The third device may be any device having a recording function, for example, a terminal device such as a video recorder, a mobile phone having a recording function, a tablet computer, or a computer equipped with a camera and having a recording function. The recording file may be a video format file, but may also be a file with other format.
It should be noted that the third device and the first device are independent devices, or the third device and the first device are not connected in the same network. And recording the displayed file with the specified format through third equipment to obtain each graph coding image in the file with the specified format, and extracting each part of data of the data to be transmitted from the graph coding images to obtain the data to be transmitted so as to realize the transmission of the data to be transmitted.
By way of example only, in one particular application scenario, the first device may be a device in a secure environment, the device being not connected to a network, or being connected only to a network within the secure environment; by the data processing method in the above embodiment, the data to be transmitted in the first device may be transmitted to an external device outside the secure environment.
In the data processing method, the image group containing at least one image coding image is converted into a file with a specified format, and the file with the specified format has the function of automatically switching and displaying the images in the image group when the file with the specified format is opened, so that the image coding images in the image group can be automatically switched and displayed without manual operation switching of a user when the file with the specified format is opened, a recording file can be obtained by recording the file with the specified format, and the transmission of data to be transmitted from the first equipment to other equipment can be realized through the recording file. The mode is simple and convenient to operate, and when the data volume needing to be transmitted is large, data transmission can be rapidly realized, and the data transmission efficiency is improved.
The following embodiment describes a specific implementation manner of generating an image group corresponding to data to be transmitted. When generating the image group, dividing data to be transmitted into at least one subdata; generating a graphic coding image containing the subdata for each subdata; determining the graph coding image corresponding to each subdata as an image group; the number of pictures of the graphic coded picture contained in the picture group is matched with the number of the sub-data of the at least one sub-data. Specifically, the number of the images of the image group of the image coded image is the same as the number of the subdata of the at least one subdata; for example, if the data to be transmitted is divided into three sub-data, three graphics-encoded images are generated.
When dividing the subdata, determining the data volume of the subdata according to the data capacity of the image coded by the graph; and dividing the data to be transmitted into at least one piece of sub data based on the data volume of the sub data. The data capacity of a graphics coded image may be understood as the amount of data that the graphics coded image can store; and then, starting from the first data of the data to be transmitted, dividing to obtain sub-data when the data volume of the sub-data is reached, and so on, wherein the data volume of the last residual data is possibly less than or equal to the data volume of the sub-data, and at the moment, the residual data volume is also used as the sub-data and is stored through a graphic coding image. And carrying out graphic coding on each subdata to obtain a graphic coding image of the subdata.
In practical implementation, a plurality of graphic coding modes can be adopted to code the sub-data, so as to obtain different graphic coding images. For example, the graphical encoded image may be a two-dimensional code image or a barcode image. And coding the sub-data by adopting a related two-dimensional code coding mode to obtain a two-dimensional code image, and coding the sub-data by adopting a related bar code coding mode to obtain a bar code image. In other embodiments, the specific graphics coding image type and the corresponding graphics coding method may be customized.
In order to improve the safety of data, when generating a graph coding image containing subdata, firstly encrypting the subdata based on a preset encryption mode; generating format data of the subdata; wherein the format data includes: the encrypted subdata, the encryption mode of the subdata, the arrangement sequence of the subdata in at least one subdata and the subdata quantity of the at least one subdata; and coding the format data to obtain a graphic coding image containing the subdata.
The Encryption method may be preset, for example, MD5 Message Digest Algorithm (MD5 Message-Digest Algorithm), DES (Data Encryption Standard) Algorithm, or the like. The encrypted subdata and the encryption mode of the subdata are stored in the format data of the subdata; therefore, when the subdata is decrypted on other equipment, the subdata can be decrypted in a decryption mode matched with the encryption mode. The associated key may be sent to the other device in other ways.
The format data of the sub-data may include, in addition to the encrypted sub-data and the encryption method of the sub-data, an arrangement order of the sub-data in the at least one sub-data, a number of the sub-data of the at least one sub-data, a data amount of the sub-data, and an end identifier of the sub-data. Wherein, the arrangement order of the sub-data in the at least one sub-data can be represented by the order identifier. The arrangement order of the sub-data in the at least one sub-data can be determined according to the position of the sub-data in the data to be transmitted. In a specific implementation, in the process of dividing the data to be transmitted into the sub-data, each sub-data is divided, and a sequential identifier is set for the sub-data. After obtaining the plurality of subdata on other equipment, the plurality of subdata can be arranged according to the sequence identifier to obtain correct data to be transmitted. The sub-data number of the at least one sub-data may be specifically understood as how many sub-data the data to be transmitted is divided into; when other equipment analyzes a plurality of subdata from the recording file, the actual number of the analyzed subdata is compared with the subdata number included in the format data, if the actual number of the analyzed subdata is the same as the subdata number included in the format data, all subdata of the data to be transmitted can be analyzed, and therefore the integrity of the final data to be transmitted is guaranteed.
The data size of the subdata can be the data size of the original subdata obtained after division; the data volume of the subdata can be used for comparing the data volume of the subdata obtained by decryption with the data volume of the original subdata after the subdata is obtained by decryption of other equipment, so that whether the subdata is lost or damaged is determined, and the integrity and the accuracy of the data to be transmitted are further ensured. The end identifier of the sub-data can be used for distinguishing each sub-data, and when the format data of a plurality of character data are sequentially arranged, graphic coding can be performed on the format data before the end identifier every time one end identifier is reached.
As an example, the format data of the sub data may be specifically divided into a data header, data, and a data trailer. The data header comprises the arrangement sequence of the sub-data in at least one sub-data, the encryption mode of the sub-data and the data volume of the sub-data. The sub-data may be stored in four bytes in the at least one sub-data, the sub-data may be stored in two bytes in an encryption manner, and both the number of the sub-data of the at least one sub-data and the data amount of the sub-data may be stored in two bytes. The data behind the data header is the encrypted sub-data. The data trailer includes an end identifier of the sub data, and may be stored using one byte.
In a specific implementation manner, when the image group is converted into a file with a specified format, a format parameter of the image group may be set first; wherein the format parameters include: the display duration of each image in the image group; the set of images is then converted to a file of a specified format based on the format parameter. The display time period here is used to control the image switching speed when switching the display of the graphics-coded image. The display time period may be set to 0.5 second, 1 second, or the like. When the specified format file is a video format file, the format parameter may be a display duration of each frame of the video frame. When the image group is converted into a file with a specified format, a graphics coded image can be converted into one frame of video frame, or a graphics coded image can be converted into a plurality of frames of video frames.
In the above embodiment, when the encoded graphic image is a two-dimensional code image, the specified format file may be understood as a large-capacity two-dimensional code format file, and the file includes a plurality of small-capacity two-dimensional code images. Under the confidential environment, the storage size of the two-dimensional code is effectively expanded in a mode of encoding the two-dimensional code image into a video, a large amount of data can be rapidly and indirectly exported, and labor time cost is saved. And the two-dimensional code content data is encrypted, so that the safety of the data is effectively guaranteed.
According to the embodiment, after the file with the specified format is opened on the first device, the file with the specified format needs to be recorded through other devices, and because the first device and the other devices are in different networks and have no communication connection relationship, after the file with the specified format is opened by the first device, the other devices are difficult to know that the file with the specified format is opened, and at this time, the file with the specified format cannot be recorded completely by the other devices.
In order to avoid the problems, after the step of converting the image group into the file with the specified format, inserting a first identifier at the head of the file with the specified format and inserting a second identifier at the tail of the file with the specified format to obtain a final file with the specified format; wherein the first identifier is used for: when the file with the specified format is opened, indicating to start recording the file with the specified format; the second identifier is for: and indicating the end of recording the file with the specified format.
The equipment for recording the file with the specified format needs to have the function of identifying the first identifier and the second identifier, and when the first identifier is identified, the recording function in the equipment can be triggered and started, so that the file with the specified format is recorded; and after the second identifier is identified, triggering to close the recording function in the equipment, thereby finishing recording the file with the specified format and obtaining the recorded file. The above-mentioned device for recording the file with the specified format is equivalent to the second device or the third device in the embodiment.
The first and second identifiers described above may be implemented in various forms. For example, in the form of an image, the first identifier may specifically be a first identifier image, and the second identifier may specifically be a second identifier image; the first identification image is inserted in front of a first graphic coding image in the file with the specified format, and when the file with the specified format is opened, the first identification image is displayed firstly, and then the first graphic coding image and subsequent graphic coding images are displayed; and the second identification image is inserted behind the last graphic coding image in the file with the specified format, and the second identification image is displayed after the last graphic coding image is displayed. In the mode, because the first identification is inserted in front of the first graphic coding image, the first graphic coding image is played after the first identification is played, a longer time can be reserved for starting the recording function of the equipment for recording the files with the specified format, the problem that the recording function is started after the graphic coding image is played is avoided, the mode is reliable, the recording effect is stable, and recording can be guaranteed to obtain complete files with the specified format under most conditions.
In another mode, the first identifier may be inserted into a first graphics coded image in the file with the specified format, but does not block a coded region in the graphics coded image; similarly, the second identifier may be inserted into the last graphics code image in the format-specified file, but does not obscure the code region in the graphics code image. The method usually needs the equipment for recording the file with the specified format to start the recording function immediately after identifying the first identifier, so that the first graphic coding image is prevented from being omitted, but the recorded file obtained by the method has short time length, small data volume and convenient transmission.
The above-described embodiments are applied to the first device. For ease of understanding, a hardware scenario of the present embodiment is described below. As shown in fig. 2, three devices are involved in the scene, where a first device is configured to generate an image group corresponding to data to be transmitted; converting the image group into a file with a specified format, and automatically switching and displaying images in the image group on a display screen of the first device; and the third equipment is used for recording the images in the automatic switching display image group to obtain a recording file. The third device has only a recording relationship with the first device, and there is usually no communication connection relationship. The third device has a communication connection relationship with the second device, such as wireless communication, wired communication or communication through a data transmission device. And after the third equipment obtains the recording file, transmitting the recording file to the second equipment.
When the first device belongs to a device in a secure environment, the third device is not typically in a communicative connection with any device outside the secure environment while recording the image. For example, when the third device is a mobile phone and the mobile phone records an image, the mobile phone needs to turn off communication signals such as a mobile signal and a wifi signal, and after the recording is completed, the mobile phone turns on the communication signals again to transmit the recorded file to the second device.
Fig. 3 provides another hardware scenario. In the scene, the second device directly records the file with the specified format, and after the second device records the recorded file, the recorded file is not required to be transmitted to other devices, and the recorded file can be processed on the device, and finally the data to be transmitted is obtained.
