[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0022] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a mobile terminal of a data transmission method according to an embodiment of the present invention. Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0023] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the data transmission method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0024] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0025] Optionally, as an optional implementation, as Figure 2 As shown, the data transmission method can be executed by a mobile terminal, a computer terminal or a similar computing device, and the specific steps include:

[0026] S202, obtaining target data to be transmitted;

[0027] S204, performing security classification on the data content corresponding to the target data, and determining security level information corresponding to at least two parts of the data content, wherein the security level information is used to indicate the security level;

[0028] S206, determining at least two target slice networks from multiple slice networks of different slice levels according to the security level information, wherein the target slice network is a slice network whose slice level matches the security level corresponding to each data content in the at least two parts of content, and slice networks of different slice levels correspond to different security levels;

[0029] S208, transmitting the data content of the target data through at least two target slice networks that match the security level.

[0030] Optionally, in this embodiment, the lighting rendering method of the above-mentioned virtual model can be but is not limited to being applied in the scenario of network slicing technology, wherein the network slicing technology can be but is not limited to cutting a physical network into multiple virtual end-to-end networks, and each virtual network, including the equipment, access, transmission and core network within the network, is logically independent, and any failure of any virtual network will not affect other virtual networks. Each virtual network has different functional characteristics and is oriented to different needs and services. Network slicing technology brings the following value: ensuring the service quality of different levels of services, including traditional network indicators such as bandwidth, latency, packet loss and jitter; enabling users to obtain a logically independent network to avoid network risks and leaks; users can view network statistics and status related to their sliced ​​packages.

[0031] However, as an on-demand customized end-to-end logical network, network slicing technology involves wireless, transmission, core network and management domains. If the capabilities of each field are arranged and combined completely, there will be a lot of choices. How to make the industry more clearly understand the capabilities of slicing and optimally match it to most industry applications is a problem that needs to be solved.

[0032] No matter how we understand the capabilities of slicing more clearly and how to best match it to most industry applications, if we still limit the logic to the overall data, then multiple local sub-data cannot be fully satisfied. For example, the target data is composed of sub-data 1, sub-data 2, and sub-data 3. The target data is judged as a whole, and a slice network with a security level 2 is selected to transmit the target data. However, the security level 2 is judged as a whole, but the security level requirements of each sub-data may vary greatly. For example, sub-data 1 has a higher security level requirement, while sub-data 2 and sub-data 3 have lower security level requirements. The resulting security level 2 is only an average security level, which can meet the security level requirements of sub-data 2 and sub-data 3, but not the security level requirements of sub-data 1, which makes it difficult to guarantee the security of sub-data 1.

[0033] Optionally, in this embodiment, the security level information is used to indicate the security level corresponding to each sub-data, and slice networks of different slice levels correspond to different security levels, such as Figure 3 As shown, the target data 302 includes multiple sub-data, such as sub-data 1, sub-data 2 and sub-data 3, among which sub-data 1 with security level 1 will use slice network A with the same security level for data transmission, sub-data 2 with security level 2 will use slice network B with the same security level for data transmission, and sub-data 3 with security level 3 will use slice network C with the same security level for data transmission.

[0034] Optionally, in this embodiment, a data transmission request is sent to at least two target slice networks, and the target slice networks assist in completing the transmission of the target data, wherein the data transmission request is used to request at least two target slice networks to transmit each sub-data according to the matching between the slice classification and the security level corresponding to each sub-data, that is, when the target data contains at least two sub-data with different security levels, the target data will be transmitted by splitting it into multiple sub-data to ensure that each sub-data can match a slice network with the same security level, so as to overcome the security defects brought about by the overall data transmission.

[0035] It should be noted that during the data transmission stage, the overall target data is split into local sub-data, and the sub-data is subjected to a finer-grained security classification to determine the security level of each sub-data. Furthermore, by allocating slice networks with different slice hierarchies to sub-data of different security levels, a targeted data transmission method is provided for each sub-data to ensure the transmission security of each sub-data.

[0036] To further illustrate, the optional Figure 3As shown, the target data 302 to be transmitted is obtained, wherein the target data 302 includes at least two sub-data, such as sub-data 1, sub-data 2, and sub-data 3; each sub-data in the target data 302 is security classified to obtain security level information, wherein the security level information is used to indicate the security level corresponding to each sub-data, such as sub-data 1 is security level 1, sub-data 2 is security level 2, and sub-data 3 is security level 3; further, according to the security level information, at least two target slice networks (such as slice network A, slice network B, slice network C) are determined from multiple slice networks of different slice levels, and the at least two target slice networks are sent. A data transmission request, wherein the target slice network is a slice network whose slice hierarchy matches the security level corresponding to each sub-data, and slice networks of different slice hierarchies correspond to different security levels. The data transmission request is used to request at least two target slice networks to transmit each sub-data according to the matching between the slice hierarchy and the security level corresponding to each sub-data, such as requesting to use slice network A with the same security level to transmit sub-data 1 with security level 1, use slice network B with the same security level to transmit sub-data 2 with security level 2, and use slice network C with the same security level to transmit sub-data 3 with security level 3.

[0037] Through the embodiments provided by the present application, during the data transmission stage, the overall target data is split into local sub-data, and the sub-data is subjected to a more fine-grained security classification to determine the security level of each sub-data. Furthermore, by allocating slice networks with different slice levels to sub-data of different security levels, a targeted data transmission method is provided for each sub-data to ensure the transmission security of each sub-data. Therefore, the problem of reduced security of data transmission can be solved, and the technical effect of improving the security of data transmission can be achieved.

[0038] As an alternative, Figure 2 As shown, before the data content corresponding to the target data is security classified and the security level information corresponding to at least two parts of the data content is determined, the method further includes: according to the time information associated with the data content, the target data is marked using a target tag to obtain the marked target data, wherein the target tag is used to mark the data in the target data corresponding to each of the data contents in the at least two parts of the content;

[0039] Before transmitting the data content of the target data through the target slice network that matches the security level in the at least two target slice networks, the method further includes: decomposing and recombining the data in the target data according to the target label to obtain at least two sub-data, wherein the sub-data is data in the target data corresponding to each data content in the at least two parts of the content;

[0040] The data content of the target data is transmitted through a target slice network that matches the security level in at least two target slice networks, including: at least two sub-data are respectively sent to at least two target slice networks for data transmission.

[0041] As an alternative, Figure 2 As shown, according to the time information associated with the data content, the target data is identified using the target tag to obtain the identified target data, including:

[0042] When the target data is video data, obtaining each frame of video content of the data content, and using the target tag to identify the video content in each frame of video content that is within a preset frame selection range, wherein the time information includes information of the preset frame selection range; or,

[0043] In the case where the target data is audio data, the audio content of each time period of the data content is obtained, and the audio content within a preset time period in the audio content of each time period is identified using the target tag, wherein the time information includes information for indicating the preset time period range; or,

[0044] When the target data is text data, the text content of each byte range of the text content is obtained, and the text content in each byte range text content within a preset byte range is identified using a target tag, wherein the time information includes information for indicating the preset byte range.

[0045] As an alternative, Figure 2 As shown, security classification is performed on the data content corresponding to the target data to determine the security level information corresponding to at least two parts of the data content, including: color marking each data content to obtain color marking information, wherein the color marking information is used to record the color marked by each data content, data contents marked with different colors correspond to different security levels, and the security level information includes the color marking information;

[0046] According to the security level information, at least two target slice networks are determined from multiple slice networks of different slice levels, including: according to the color marking information, at least two target slice networks are determined from the multiple slice networks.

[0047] It should be noted that color marking itself has a high intuitive feature, which helps users to select or view the security level more intuitively. In addition, there is little correlation between color itself and data transmission, so when illegal users steal or destroy data transmission, they also perform related illegal operations based on color, which further improves the security of data transmission.

[0048] Through the embodiments provided by the present application, each sub-data is color-marked to obtain color marking information, wherein the color marking information is used to record the color marked by each sub-data, and sub-data marked with different colors correspond to different security levels, and the security level information includes color marking information; according to the color marking information, at least two target slice networks are determined from multiple slice networks, and data transmission requests are sent to the at least two target slice networks, thereby achieving a technical effect of helping users to more intuitively select or view security levels and further improving the security of data transmission.

[0049] As an alternative, Figure 2 As shown, before color marking each data content to obtain color marking information, the method further includes: obtaining at least two colors, and mixing the at least two colors according to a preset ratio to obtain a verification color to be marked;

[0050] Performing color marking on each data content to obtain color marking information includes: performing color marking on each data content using a verification color to be marked to obtain color marking information.

[0051] As an alternative, Figure 2 As shown, at least two target slice networks are determined from the multiple slice networks according to the color marking information, including:

[0052] The color and security level marked by each data content are matched using a preset mapping relationship to obtain the security level corresponding to each data content;

[0053] When the slice level corresponding to each slice network in the multiple slice networks is obtained, the slice level corresponding to each slice network and the security level corresponding to each data content are matched, and at least two target slice networks are determined from the multiple slice networks.

[0054] To further illustrate, the optional Figure 4 The scenario shown, continues with Figure 5 As shown, according to the preset mapping relationship, the color label red corresponds to security level 1, the color label orange corresponds to security level 2, and the color label purple corresponds to security level 3.

[0055] Through the embodiments provided by the present application, a preset mapping relationship is used to match the color marked by each sub-data with the security level to obtain the security level corresponding to each sub-data; when the slice level corresponding to each slice network in multiple slice networks is obtained, the slice level corresponding to each slice network and the security level corresponding to each sub-data are matched, and at least two target slice networks are determined from the multiple slice networks; a data transmission request is sent to the at least two target slice networks, thereby achieving the technical effect of helping users to select or view the security level more intuitively and further improving the security of data transmission.

[0056] As an alternative, Figure 2 As shown, security classification is performed on the data content corresponding to the target data to determine the security level information corresponding to at least two parts of the data content, including:

[0057] S1, perform manual classification operation on each sub-data to obtain security level information; or,

[0058] S2, performing automatic classification operation on each sub-data to obtain security level information.

[0059] It should be noted that in order to improve the execution flexibility of classification operations, security classification is subdivided into manual classification operations and automatic classification operations, among which manual classification operations can be understood but not limited to being understood as the user manually performing security classification on each sub-data, and automatic classification operations can be understood but not limited to being understood as automatically performing security classification on each sub-data for the user.

[0060] Through the embodiments provided in the present application, a manual classification operation is performed on each sub-data to obtain security level information; or, an automatic classification operation is performed on each sub-data to obtain security level information, thereby achieving the purpose of subdividing security classification into manual classification operations and automatic classification operations, thereby achieving the technical effect of improving the execution flexibility of classification operations.

[0061] As an alternative, Figure 2 As shown, manual classification operations are performed on each sub-data to obtain security level information, including:

[0062] S1, in response to a long press operation performed on a first target sub-data among at least two sub-data, displaying multiple slice levels corresponding to multiple slice networks simultaneously or sequentially; determining a first slice level from the multiple slice levels as a security level corresponding to the first target sub-data; or,

[0063] S2, in response to a first selection operation performed on a second target sub-data among the at least two sub-data and a second selection operation performed on a second slice level among the multiple slice levels, taking the second slice level as a security level corresponding to the second target sub-data.

[0064] It should be noted that manual classification operations can improve the accuracy of selecting the security level of sub-data, and the selected security level can better meet user needs, but at the same time manual classification operations can also reduce the efficiency of selecting the security level. Therefore, in this embodiment, a variety of execution methods for manual classification operations are provided. Users can choose the most suitable execution method according to their own operating habits to efficiently complete the manual classification operation.

[0065] To further illustrate, the optional Figure 4 As shown, in response to a long press operation performed on a first target sub-data (such as sub-data 1) among at least two sub-data, multiple slice levels (such as security level 1, security level 2, security level 3) corresponding to multiple slice networks are displayed simultaneously or sequentially; security level 3 (first slice level) is determined from the multiple slice levels as the security level corresponding to sub-data 1 (first target sub-data).

[0066] Through the embodiments provided by the present application, in response to a long press operation performed on a first target sub-data among at least two sub-data, multiple slice levels corresponding to multiple slice networks are displayed simultaneously or sequentially; a first slice level is determined from the multiple slice levels as the security level corresponding to the first target sub-data; or, in response to a first selection operation performed on a second target sub-data among at least two sub-data, and a second selection operation performed on a second slice level among the multiple slice levels, the second slice level is used as the security level corresponding to the second target sub-data, thereby achieving a technical effect of improving the accuracy of selecting the security level of the sub-data.

[0067] As an optional solution, obtaining the target data to be transmitted includes: obtaining the target data associated with the target account;

[0068] Automatic classification operations are performed on each sub-data to obtain security level information, including:

[0069] Obtain the historical security level corresponding to the historical data that has been transmitted by the target account;

[0070] The historical data are counted using the historical security levels to obtain first key data, wherein the first key data corresponds to the same or similar historical security levels for multiple times;

[0071] When the target data contains the first key data, the security level corresponding to the first key data contained in the target data is automatically determined to be the same or similar historical security level, or the first key data is highlighted in the target data, and it is prompted that the security level corresponding to the first key data is the same or similar historical security level.

[0072] It should be noted that the automatic classification operation can improve the efficiency of selecting the security level of sub-data, but at the same time the automatic classification operation will also reduce the accuracy of selecting the security level. In this embodiment, the historical security level is combined to perform statistics on historical data to obtain sub-data with the same security level selected by the user through multiple classification operations. This improves the efficiency of selecting the security level of the sub-data while ensuring the accuracy of selecting the security level of the sub-data.

[0073] Through the embodiments provided by the present application, the historical security level corresponding to the historical data that has been transmitted by the target account is obtained; the historical data is counted using the historical security level to obtain the first key data, wherein the first key data corresponds to multiple identical or similar historical security levels; when the target data contains the first key data, the security level corresponding to the first key data contained in the target data is automatically determined as the same or similar historical security level, or the first key data is highlighted in the target data, and it is prompted that the security level corresponding to the first key data is the same or similar historical security level, thereby achieving the purpose and realizing the technical effect.

[0074] As an optional solution, automatic classification operations are performed on each sub-data to obtain security level information, including:

[0075] S1, obtaining data reference information of each sub-data, wherein the data reference information includes at least one of the following: data source information, data type information, and data protocol information;

[0076] S2, performing automatic classification operations on each sub-data based on the data reference information to obtain security level information.

[0077] Optionally, in this embodiment, data reference information can be understood but not limited to information of different dimensions used in the execution of automatic classification operations. The more dimensions of the data reference information, the higher the execution accuracy of the automatic classification operation, but at the same time, the execution efficiency of the automatic classification operation will also decrease. Therefore, selection can be made as needed among the data source information, data type information, and data protocol information to take into account both the execution accuracy and efficiency of the automatic classification operation.

[0078] Optionally, in this embodiment, data source information can be used but is not limited to indicate the source of sub-data. For example, if the source is from related applications or platforms involving data security, the security level of the sub-data needs to be improved; data type information can be used but is not limited to indicate the type of sub-data. For example, if the sub-data itself is a data type with higher security level requirements, involving security information, virtual resources, etc., then a higher security level needs to be configured; data protocol information can be used but is not limited to indicate the protocol type of sub-data. For example, when the sub-data uses the https protocol, a higher security level can be assigned.

[0079] Through the embodiments provided in the present application, data reference information of each sub-data is obtained, wherein the data reference information includes at least one of the following: data source information, data type information, and data protocol information; based on the data reference information, automatic classification operations are performed on each sub-data to obtain security level information, thereby achieving a technical effect that takes into account both the execution accuracy and efficiency of the automatic classification operation.

[0080] As an optional solution, before sending the data transmission request to at least two target slice networks, the method further includes:

[0081] The sub-data are reorganized into data streams to be transmitted with different security levels, and a target tag is configured for each data stream to be transmitted, wherein the data content of the target tag includes a color representation value.

[0082] It should be noted that individual sub-data usually does not conform to the format of data transmission, or cannot be transmitted stably. In order to ensure the stability of data transmission, each sub-data is reorganized into data streams with different security levels to be transmitted. At the same time, in order to ensure that the matching slice network can be used to complete data transmission smoothly, a target label is also configured for each data stream to be transmitted, where the data content of the target label includes a color representation value.

[0083] Through the embodiments provided in the present application, each sub-data is reorganized into data streams to be transmitted with different security levels, and a target tag is configured for each data stream to be transmitted, wherein the data content of the target tag includes a color representation value, thereby achieving the technical effect of ensuring the stability of data transmission.

[0084] As an optional solution, after determining at least two target slice networks from a plurality of slice networks of different slice hierarchies according to the security level information and sending a data transmission request to the at least two target slice networks, the method further includes:

[0085] S1, obtaining transmission feedback information returned by the first client, wherein the transmission feedback information carries the actual security level corresponding to each sub-data when the first client receives the target data, and the first client is the transmission recipient of the target data;

[0086] S2, verifying the actual security level corresponding to each sub-data and the security level corresponding to each sub-data, and treating the sub-data with different actual security levels as abnormal data.

[0087] It should be noted that in order to further improve the security of data transmission, a feedback mechanism is set in this embodiment. When the actual security level carried in the transmission feedback information returned by the first client is inconsistent with the security level set at the beginning of data transmission, it can be considered that there are problems such as data tampering, data destruction, and data theft during the data transmission process, and the sub-data is then regarded as abnormal data, and relevant responses are made in a timely manner to minimize the loss caused by data anomalies.

[0088] Through the embodiments provided in the present application, transmission feedback information returned by the first client is obtained, wherein the transmission feedback information carries the actual security level corresponding to each sub-data when the first client receives the target data, and the first client is the transmission recipient of the target data; the actual security level corresponding to each sub-data and the security level corresponding to each sub-data are verified, and the sub-data with differences in actual security levels are treated as abnormal data, thereby achieving the purpose of providing a feedback mechanism for data transmission, thereby realizing the technical effect of improving the security of data transmission.

[0089] Optionally, as another optional implementation, the data transmission method may also be executed by a mobile terminal, a computer terminal or a similar computing device, and the specific steps include:

[0100] As an optional solution, for ease of understanding, the above data transmission method is applied to 5G network scenarios with slice connections and terminal devices that support 5G slicing technology. For example, this embodiment is applied to devices with wired and wireless data transmission capabilities, including mobile phones, CPE, data cards, etc., and to applications based on data devices. This embodiment is used for data transmission. This embodiment can also be applied to existing technical scenarios. The existing application scenario can be to use color-coded information to transmit existing data channels. Strictly speaking, the security levels of existing data channels are from large to small: VPN connection, cellular connection, strong encryption hotspot connection or ordinary wifi connection; the future application scenario is a network that supports security slice levels, which can be applied when this embodiment involves deployment.

[0101] It should be noted that this embodiment aims to solve the four major problems of user data access privacy leakage, data transmission being eavesdropped, counterfeited, and tampered with from the perspective of underlying data transmission. The technical means adopted in this embodiment are: proposing a technical method for users to visually use hierarchical slices and quickly confirm whether data has been leaked. The terminal uses data information of different security levels to correspond to slice networks of different security levels (such as 5G slice networks) according to the user's visualization color setting for encrypted data segments, and uses slice networks of different security levels to transmit data simultaneously. When a group of information starts to be transmitted, the verification color of the overall sent data information is calculated according to the visualization color settings of different data segments. After the receiving end completes the reception of a group of data, the verification color is restored according to the received data information, and the return is used by the sending end for the sender to quickly visually confirm that the data has not been tampered with or counterfeited.

[0102] Optionally, in this embodiment, Figure 6 As shown, multiple modules are involved, such as a user data information security level color representation interaction module, a user data information security level acquisition module, a user data decomposition identification module, a classification data flow generation and parsing module, a level slice data flow control module, and a level slice control module.

[0103] To further illustrate, this embodiment mainly addresses four major issues: leakage of Internet access privacy traces, eavesdropping, counterfeiting, and tampering of data transmission. The above issues are solved from the perspective of underlying data transmission. The specific steps are as follows:

[0104] Step S101: The terminal information input interface provides the user with a 5-level color card, indicating the correspondence between the 5 levels of slices, such as red corresponding to slice level L4, orange corresponding to slice level L3, purple corresponding to slice level L2, yellow corresponding to slice level L1, and blue corresponding to slice level L0. The color card is not limited to a single color system. The module completed in step S101 can be Figure 6 The user data information security level color in the interactive module indicates.

[0105] Optionally, in this embodiment, for a piece of information that the user is about to send, the user can set any word, phrase, sentence, or paragraph to any color. The setting method is to long press to automatically change the color, or select the color through the color card after selecting the content. Among them, the transmission form of pictures, videos, and audio is data, so this embodiment is not limited to text information, and this embodiment is also applicable to multimedia information. For pictures and videos, the user can frame a certain display area in the playback display frame and use any security level slice connection for transmission. It can be framed with shapes such as circles and squares, and the frame is also set with the corresponding security level color. For audio, the user can set the security level slice on the playback progress bar and mark it with the corresponding security level color. The above method is still applicable to streaming media video. In the local video playback window, the user can frame a certain display area and use any security level slice connection for transmission. For streaming video and audio, another method available to users is to use any security level slice connection to transmit the video or audio of a time period. When there is secret video and audio transmission, press and hold the color button corresponding to the corresponding security slice connection. The video or audio of the time period is sent through the security slice connection corresponding to the button. The module for completing the above color setting can be Figure 6 The user data information security level colors shown in the figure represent the interactive modules.

[0106] Optionally, in this embodiment, a convenient method may be provided to the user, namely, automatic setting according to industry big data and automatic setting according to user habits, wherein the automatic setting according to industry big data includes the following aspects:

[0107] 1-1. General security guidelines Private data, name, phone number, ID number, address, parents, spouse, children's information, user name, password, etc. (privacy data is legal data that users are allowed to obtain).

[0108] 1-2. Highly sensitive industry security data, contracts, quotations, circuit diagrams, flow charts, formulas, technical documents, etc. (Highly sensitive industry security data are legal data that users are allowed to obtain).

[0109] 1-3. Safety phrases frequently set by users.

[0110] 1-4. Automatically set according to user habits, that is, when the user chooses to automatically set according to habits, the terminal will count the frequency of color selection in a certain sentence, word, or character based on the user's setting history, automatically select the color setting with a higher frequency, and present it to the user. When it is recognized that the user has entered privacy and security information (according to user habits or industry big data matching is successful), the user will be prompted and an auxiliary toolbar for security level color setting will automatically pop up to facilitate user settings, or it will automatically match a security level and provide an auxiliary toolbar that the user can modify. The completion modules for the above automatic setting according to industry big data and automatic setting according to user habits can be Figure 6 The user data information security level colors shown in the figure represent the interactive modules.

[0111] Step S102: This embodiment also provides a method for automatically identifying private data and automatically transmitting the private data through slices with a high security level, and the means include:

[0112] 2-1. Desktop application icons will be set with corresponding color areas. Different colors correspond to different levels of security slices. When the application transmits data, the corresponding slice is used by default for data transmission. For example, if the user identifies a higher level of regional data in the application, the higher level slice can be used to transmit the calibration data. The system will place applications with payment functions in the high-level color area by default. Users can drag applications that they think need a high security level into the higher level color area.

[0113] 2-2. Automatically identify the URL. When the URL is a bank website, it will automatically use a high-security slice connection, and the border will display the corresponding color.

[0114] 2-3. Automatically identify the upper-layer data protocol type. When opening a web page and using the https protocol, it automatically uses a high-security slice connection, and the border will display the corresponding color.

[0115] Step S103: Find the corresponding security level slice according to the color information set by the user; collect the user data information according to the color information. For image and video data, the framed data can be separated by frame, and the data of different color frames can be extracted and classified; for audio data, the data can be extracted and classified according to the set time period. The completion module of step S103 can be Figure 6 The user data information security level collection module shown in .

[0116] Step S104: Mark the data according to the word order to facilitate decomposition and reorganization. Reorganize the data information into several levels of data streams to be transmitted according to the color level, corresponding to the level slices. Label each data stream, the label is hexadecimal data, and the data content is RGB color representation value. The completion module of step S104 can be Figure 6 The user data shown in FIG. 1 is decomposed into identification modules.

[0117] Step S105: Present the verification color of the data that the user is about to send, and the presentation method may be a flashing border color or a color block prompt on the screen. The completion module of step S105 is Figure 6 The user data information security level colors shown in the figure represent the interactive modules.

[0118] Optionally, in this embodiment, the verification color may be a mixed color, wherein the mixed color calculation method is:

[0119] Color 1*(Color 1-Color 2)*(1-Percentage of Color 1)

[0120] Color 1: {255,255,255}, Color 2: {199,199,199}

[0121] R: 255*(255-199)*(1-percentage of color 1)

[0122] G: 255*(255-199)*(1-percentage of color 1)

[0123] B: 255*(255-199)*(1-the percentage of color 1)

[0124] The principle of the color mixing calculation includes: mixing two colors to generate a new color, and performing recursive calculations, that is, mixing the first color with the second color to calculate the first composite color, mixing the first composite color with the third color to calculate the second composite color, and finally calculating the final composite color of all the colors.

[0125] The percentage of the color is calculated as:

[0126] First color percentage = first color statistical word count / (first color statistical word count + second color statistical word count)

[0127] Second color percentage = second color statistical word count / (first color statistical word count + second color statistical word count)

[0128] The percentage calculation occurs when mixing two colors. The RGB values ​​in the color are calculated using the formula separately. The final composite color is the calibration color.

[0129] The completion module of the above color mixing calculation is Figure 6 The user data information security level colors shown in the figure represent the interactive modules.

[0130] Step S106: The terminal creates a data stream to be transmitted according to each type of label data, and embeds the hierarchical slice information in the data stream information. The completion module of step S106 can be Figure 6 The classification data stream generation and parsing module shown in .

[0131] Step S107: The terminal initiates a slice connection request of each level to the wireless protocol module URSP, and establishes slice connections of each level with the network. The completion module of step S107 can be Figure 6 The hierarchical slicing control module shown in .

[0132] Step S108: The terminal transmits the corresponding encrypted data stream in the established hierarchical slice connection respectively. The data stream transmission uses the TCP protocol. In the TCP protocol handshake process, the slice information and the corresponding color information are exchanged. The completion module of step S108 can be Figure 6 The level slice data flow control module shown in .

[0133] Optionally, in this embodiment, encryption information and color fields are added to the TCP message header option part, and the data is expressed as follows:

[0134] Slice security classification: value ranges from 0 to 1 (occupies 1 byte)

[0135] Security RGB: value {0~255, 0~255, 0~255} (occupies 3 bytes)

[0136] Step S109: After receiving the data and slice information, the receiving end parses and reassembles the data stream. The completion module of step S109 can be Figure 6 The classification data stream generation and parsing module shown in .

[0137] Step S110: Display the secret information in color according to the data identification information. At the same time, the receiving end can choose to perform secondary processing on the relevant sensitive fields according to the slice confidentiality information, including burning after reading, blurring display before the owner authentication, automatic storage in the security partition, etc. The completion module of step S110 can be Figure 6 The user data information security level colors shown in the figure represent the interactive modules.

[0138] Step S111: The calculation method of step S105 at the receiving end calculates the verification color and transmits the calculated verification color back to the sending end, so that the sending end can determine whether the data has been tampered with or impersonated. The completion module of step S111 can be Figure 6 The user data information security level colors shown in the figure represent the interactive modules.

[0139] Through the embodiments provided in the present application, the privacy and security issues of user data transmission are solved from the perspective of underlying multi-channel transmission, and a method for users to visually use hierarchical slicing is provided. Users can very conveniently use secure hierarchical slicing to hierarchically transmit their own private data, thereby further strengthening user privacy protection and data security protection, making privacy eavesdropping, data forgery, and data tampering impossible, and increasing the security of terminal data transmission.
