Technical Field

[0001] This application belongs to the field of data processing technology, and in particular relates to a data transmission method, apparatus, device, and computer storage medium. Background Technology

[0002] With the continuous development of internet information technology, the types of devices used by users are increasing, and there is a frequent need for data transmission between different devices. For the transmission of private data, encryption is required before data can be transmitted.

[0003] In existing technologies, when transmitting private data, the data sending device encrypts the original data to be transmitted using at least one encryption algorithm, sends the encrypted data to the data receiving device, and the data receiving device decrypts the encrypted data using a decryption algorithm to obtain the original data. To ensure the security of private data, the encryption and decryption process needs to be quite complex, resulting in low data transmission efficiency. Furthermore, the data sending and receiving devices need to use matching encryption and decryption algorithms to transmit private data, leading to poor flexibility in data transmission. Summary of the Invention

The server does not need to use complex encryption algorithms to encrypt privacy data, and the first device does not need to use complex decryption algorithms to decrypt the encrypted data. The data encryption and decryption process is implemented through an electronic identity certificate. During data transmission, the electronic identity certificate does not need to be transmitted. While ensuring the security of privacy data, the efficiency and flexibility of data transmission are improved.

[0094] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0095] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0096] With the continuous development of internet information technology, the types of devices used by users are increasing, and there is a frequent need for data transmission between different devices. For the transmission of private data, encryption is required before data can be transmitted.

[0097] In existing technologies, when transmitting private data, the data sending device encrypts the original data to be transmitted using at least one encryption algorithm, sends the encrypted data to the data receiving device, and the data receiving device decrypts the encrypted data using a decryption algorithm to obtain the original data. To ensure the security of private data, the encryption and decryption process needs to be quite complex, resulting in low data transmission efficiency. Furthermore, the data sending and receiving devices need to use matching encryption and decryption algorithms to transmit private data, leading to poor flexibility in data transmission.

[0098] To address the problems of the prior art, embodiments of this application provide a data transmission method, apparatus, device, and computer storage medium. The data transmission method provided in embodiments of this application is applied to, for example... Figure 1 The data transmission system shown is as follows: Figure 1As shown, the data transmission system includes a first device 110, a second device 120, and a server 130. Both the first device 110 and the second device 120 are equipped with a Super SIM card. The server 130 is the backend data management server for the Super SIM card. Shared data between the first device 110 and the second device 120 can be stored in the server 130, and each shared data has a unique data identifier. When the second device 120 wants to share data with the first device 110 and transmit data to it, it sends a data identifier to the first device 110. The first device 110 then retrieves the corresponding shared data from the server 130 based on the received data identifier from the second device 120. The server does not need to use complex encryption algorithms to encrypt the privacy data, and the first device does not need to use complex decryption algorithms to decrypt the encrypted data. The data encryption and decryption process is implemented through an electronic identity certificate. During data transmission, the electronic identity certificate does not need to be transmitted, thus improving data transmission efficiency and flexibility while ensuring the security of privacy data.

[0099] The data transmission method provided in the embodiments of this application will be described below.

[0100] Figure 2 A schematic flowchart of a data transmission method provided in one embodiment of this application is shown.

[0101] like Figure 2 As shown, the data transmission method provided in this application includes the following steps.

[0102] S210, the first device receives first shared information sent by the second device, the first shared information including a first data identifier.

[0103] Here, the first device acts as the receiving terminal device, and the second device acts as the sending terminal device. The data identifier refers to a unique identifier for the shared data; it can be a data storage identifier or an identification code.

[0104] In some embodiments, the first shared information may be sent via SMS or 5G messaging. When data transmission is required, the second device sends the first shared information to the first device, the first shared information including a first data identifier of the first shared data.

[0105] In some embodiments, information can be transmitted via SMS or 5G messaging, ensuring that information can be transmitted even in weak network environments with poor network signals.

[0106] In some embodiments, the second device may receive a user's selection input regarding a recipient user identifier in the Super SIM card. In response to this selection input, the second device sends first shared information to the first device corresponding to the recipient user identifier via the core network. Here, the user identifier is used to uniquely identify the device; the user identifier may be a user's number, code, etc.

[0107] S220. The first device determines the first target information processing method corresponding to the usage status of the first device based on the relationship information between the usage status and the information processing method, and obtains the first user identifier of the first device using the first target information processing method.

[0108] Here, the relationship between usage status and information processing method is predetermined. The first user identifier uniquely identifies the first device. For example, the first user identifier is the user's number.

[0109] In some embodiments, the first target information processing method can be either a first information processing method or a second information processing method. When the usage state is "in use," the corresponding information processing method is the first information processing method, and the first device uses the first information processing method to obtain the first user identifier of the first device. When the usage state is "not in use," the corresponding information processing method is the second information processing method, and the first device uses the second information processing method to obtain the first user identifier of the first device.

[0110] S230, the first device sends a first acquisition request to the server, the first acquisition request including a first data identifier and a first user identifier.

[0111] Here, the server can be a data management server.

[0112] In some embodiments, after obtaining the first user identifier, the first device sends a first acquisition request to the server. The first acquisition request carries a first data identifier and a first user identifier, and is used by the first device to obtain the first shared data corresponding to the first data identifier from the server.

[0113] S240. The server queries the first encrypted data corresponding to the first data identifier. The first encrypted data is the data obtained by the server encrypting the first shared data using the electronic identity certificate corresponding to the first target identifier.

[0114] Here, the first encrypted data is the data encrypted from the first shared data.

[0115] In some embodiments, when the second device sends the first shared information to the first device via the core network, the core network sends an encryption instruction carrying the first data identifier and the recipient user identifier to the server. It is understood that when the second device sends an SMS or 5G message to the first device, it needs to carry the first user identifier of the first device. The first user identifier is also the recipient user identifier. Upon receiving the encryption instruction, the server obtains the first shared data corresponding to the first data identifier and the electronic identity certificate corresponding to the first user identifier, and uses the electronic identity certificate corresponding to the first user identifier to encrypt the first shared data, obtaining the first encrypted data.

[0116] In some embodiments, before the server receives the first acquisition request, the server has already encrypted the first shared data using the electronic identity certificate corresponding to the first target identifier, thus obtaining the first encrypted data. It should be noted that the electronic identity certificate serves as the encryption key in the encryption process.

[0117] In some embodiments, after generating a Trusted Electronic Identity Certificate (CTID) for the first time, the terminal device can store the CTID on its Super SIM card for easy display as needed. Simultaneously, the terminal device can upload the CTID and the user identifier corresponding to the Super SIM card used to store the CTID locally to the server for storage. This allows the server to subsequently determine the corresponding CTID based on the user identifier of the Super SIM card.

[0118] In some embodiments, after receiving the first acquisition request, the server needs to authenticate the identity of the first device and first acquire the first encrypted data corresponding to the first data identifier.

[0119] S250, The server obtains the first target identifier corresponding to the first encrypted data.

[0120] In some embodiments, during the authentication process, it is necessary to verify the first user identifier of the first device. Because the first device wants to obtain the first shared data, after the server determines the first encrypted data after encrypting the first shared data, it obtains the first target identifier corresponding to the first encrypted data. The first target identifier is used to authenticate the first device. S260: The server compares the first target identifier and the first user identifier.

[0121] S270, if the first target identifier and the first user identifier match, the server sends the first encrypted data to the first device.

[0122] In some embodiments, a first target identifier corresponding to the first encrypted data is compared with a first user identifier of the first device. If the first target identifier and the first user identifier match, the first device authentication is successful, and the server sends the first encrypted data to the first device.

[0123] In some embodiments, if authentication fails, that is, if the first target identifier and the first user identifier do not match, the server sends target information to the first device. The target information indicates that authentication has failed and the server refuses to send the first encrypted data to the first device.

[0124] S280, the first device uses the electronic identity certificate corresponding to the first user identifier to decrypt the first encrypted data and obtain the first shared data.

[0125] In some embodiments, the first device uses the electronic identity certificate corresponding to the first user identifier as a decryption key to decrypt the first encrypted data, thereby obtaining the first shared data. Here, the electronic identity certificate corresponding to the first user identifier can be stored in the super SIM card of the first device.

[0126] In this way, the server does not need to use complex encryption algorithms to encrypt private data, and the first device does not need to use complex decryption algorithms to decrypt the encrypted data. The data encryption and decryption process is realized through electronic identity certificates. During data transmission, electronic identity certificates do not need to be transmitted. While ensuring the security of private data, the efficiency and flexibility of data transmission are improved.

[0127] Based on this, in some embodiments, such as Figure 3 As shown, after S280 above, the method may further include:

[0128] S310, The first device displays the first shared data;

[0129] S320, The first device receives the modification input of the first shared data;

[0130] S330, the first device responds to the modified input, modifies the first shared data, and obtains the second shared data.

[0131] In some embodiments, the first shared data may be data such as images, text, tables, videos, audio, or numbers. Upon receiving the first shared data, the first device may directly display it.

[0132] In some embodiments, upon receiving the first shared data, the first device may also display a prompt window to ask the user whether to display the first shared data. Upon receiving user input regarding the display of the first shared data, the first shared data is displayed.

[0133] In some embodiments, the first device may also receive modification input for the first shared data. For example, editing a table or retouching an image. In response to the modification input, the first device modifies the first shared data to obtain second shared data. The first device then saves the second shared data.

[0134] Specifically, in response to modified input, the first device's super SIM card can, based on the data type (image, text, table, video, audio, or numbers, etc.), call the corresponding data processing app through the SIM card channel to modify the first shared data and obtain the second shared data. The first device can also display the second shared data.

[0135] In this way, the first device can display the first shared data to the user so that the user can access the relevant content. It also provides modification functionality, allowing the user to easily modify the first shared data.

[0136] Based on this, in some embodiments, the first device includes a super SIM card; the above-mentioned S220 may specifically include:

[0137] If the usage status of the first device indicates that it is in use, obtain the account information of the application opened on the first device;

[0138] Compare the application's account information with the application's default account information stored in the Super SIM card;

[0139] If the account information matches the preset account information, obtain the first user identifier of the first device from the Super SIM card;

[0140] Specifically, S310 may include:

[0141] Display the first shared data in the application's display interface.

[0142] In some embodiments, when the usage status of the first device indicates that it is in use, user authentication is required. The account information of the application currently open (in use) on the first device is obtained, and compared with the application's default account information stored in the Super SIM card to determine whether the user of the first device is the owner of the device. If the account information matches the default account information, the first user identifier of the first device is obtained from the Super SIM card. A first acquisition request is generated based on the first user identifier and the first data identifier of the first device. If the account information matches the default account information, the first shared information is hidden. The usage status of the first device is determined every preset time period, and the corresponding information processing method is determined accordingly, until authentication is successful, at which point the first user identifier is obtained.

[0143] As an example, such as Figure 4 As shown, when the first device is in use, the first interface is displaying the interface of another application. At this time, if the first shared data is obtained, the Super SIM card can send the decrypted first shared data to the currently used application through the activated SIM card channel, and the first shared data can be displayed in the application's display interface as a pop-up window.

[0144] In this way, when the usage status of the first device indicates that it is in use, the account information of the application opened on the first device is obtained to authenticate the user's identity. Only after successful authentication can the first shared data be obtained, thus further ensuring the security of the first shared data.

[0145] Based on this, in some embodiments, the first device includes a super SIM card; the above-mentioned S220 may specifically include:

[0146] If the usage status of the first device indicates that it is not in use, a reminder message for the first shared information will be displayed in the information prompt interface;

[0147] If user authentication is successful and the input for obtaining the first shared data is received, the first user identifier of the first device is obtained from the Super SIM card;

[0148] Specifically, S310 may include:

[0149] The first shared data is displayed in the information prompt interface.

[0150] Here, the information notification interface can be the lock screen interface.

[0151] In some embodiments, when the usage status of the first device indicates that it is not in use, a reminder message for the first shared information is displayed in the information prompt interface. To view the specific content, the user needs to be authenticated. If the user authentication is successful and an input to acquire the first shared data is received, the first user identifier of the first device is obtained from the Super SIM card. A first acquisition request is then generated based on the first user identifier and the first data identifier of the first device.

[0152] As an example, such as Figure 5 As shown, the notification message for the first shared information displayed on the information prompt interface includes a "View Now" button. In response to the user clicking this button, a data retrieval command is triggered to perform user authentication, requiring the user to unlock the first device. Only after successful user authentication can the first user identifier of the first device be obtained from the Super SIM card.

[0153] As an example, such as Figure 6 As shown, when the usage status of the first device indicates that it is not in use, the first device can directly display the first shared data in the information prompt interface. The first device can receive user input to save or modify, and in response to the save or modify input, save or modify the first shared data.

[0154] In this way, when the usage status of the first device indicates that it is not in use, a reminder message for the first shared information is displayed in the information prompt interface, and the user's identity is authenticated. Only after successful authentication can the first shared data be obtained, thus further ensuring the security of the first shared data.

[0155] Based on this, in some embodiments, such as Figure 7 As shown, after S330 above, the method may further include:

[0156] S410, the first device sends the second shared data and the first user identifier to the server.

[0157] S420. When the server obtains the reception time of the second shared data and the first device information corresponding to the first user identifier, it generates a second data identifier for the second shared data using the first user identifier, the reception time of the second shared data, and the first device information.

[0158] S430, The server sends the second data identifier to the first device;

[0159] S440, The first device obtains the second user identifier of the second device;

[0160] S450, The first device sends the second shared information to the second device corresponding to the second user identifier;

[0161] S460. The second device determines the second target information processing method corresponding to the usage status of the second device based on the relationship information between the usage status and the information processing method, and obtains the second user identifier of the second device using the second target information processing method.

[0162] S470, The second device sends a second acquisition request to the server;

[0163] S480. The server queries the second encrypted data corresponding to the second data identifier, obtains the second target identifier corresponding to the second encrypted data, compares the second target identifier with the second user identifier, and sends the second encrypted data to the second device if the second target identifier and the second user identifier match.

[0164] S490, The second device uses the electronic identity certificate corresponding to the second user identifier to decrypt the second encrypted data and obtain the second shared data;

[0165] The second shared information includes a second data identifier, the second acquisition request includes a second data identifier and a second user identifier, and the second encrypted data is data obtained by the server encrypting the second shared data using the electronic identity card corresponding to the second target identifier.

[0166] In some embodiments, the first device may also act as a sending terminal device to send the second shared data to the second device, and the second device may act as a data receiving terminal device.

[0167] In some embodiments, the first device sends second shared data and a first user identifier to the server. The server stores the second shared data and, upon obtaining the reception time of the second shared data and the first device information corresponding to the first user identifier, generates a second data identifier for the second shared data using the first user identifier, the reception time of the second shared data, and the first device information, and sends it to the first device. However, the second device cannot view the second shared data at this time. The first device, as a data sending terminal device, needs to send second shared information to the second device so that the second device can obtain the second shared data from the server.

[0168] In some embodiments, the first device stores a second data identifier in its own super SIM card's storage folder for use in obtaining a second user identifier from the second device and sending first sharing information to the second device corresponding to the second user identifier. Before the first device sends the sharing information to the second device, the user needs to select between the second user identifier and the second data identifier. Figure 8 As shown, users can view the shared data uploaded to the server and saved through the front-end access interface corresponding to the storage folder of the Super SIM card, and receive user input through this front-end access interface. The interface receives user input regarding the selection of shared files to determine the second data identifier. It also receives user input regarding the selection of the recipient user, choosing the contact corresponding to the second user identifier, and receives input regarding clicking the send button. In response to this click, the first device sends the shared information to the second device.

[0169] In some embodiments, similar to the first device acquiring the first shared data, the second device, after receiving the second data identifier, can acquire the second shared data corresponding to the second data identifier from the server.

[0170] In this way, even if the roles of the receiving and sending terminal devices are reversed, data transmission can still be achieved. During data transmission, the server does not need to use complex encryption algorithms to encrypt private data, and the second device does not need to use complex decryption algorithms to decrypt encrypted data. The data encryption and decryption process is implemented through electronic identity certificates. During data transmission, electronic identity certificates do not need to be transmitted. While ensuring the security of private data, data transmission efficiency and flexibility are improved.

[0171] Based on this, in some embodiments, such as Figure 9 As shown, after S330 above, the method may further include:

[0172] S510, The first device receives the reply input of the first shared information;

[0173] S520, the first device responds to the reply input by sending reply information to the server. The reply information includes the second user identifier of the second device, the second shared data, and the first user identifier.

[0174] S530. When the server obtains the reception time of the second shared data and the first device information corresponding to the first user identifier, it generates a second data identifier for the second shared data using the first user identifier, the reception time of the second shared data, and the first device information.

[0175] S540, The server sends the second data identifier to the second device corresponding to the second user identifier and the first device corresponding to the first user identifier.

[0176] In some embodiments, such as Figure 10 As shown, the first device can receive modification input for the first shared data. For example, editing a table or retouching an image. In response to the modification input, the first device modifies the first shared data to obtain the second shared data. The first device can display the second shared data; the first device can also save the second shared data in response to the user's save input; the first device can also receive reply input for the first shared data, and in response to the reply input, the first device sends a reply message to the server.

[0177] In some embodiments, the server can determine the processing flow (transmission to the first or second device) of the second shared data based on the recipient user identifier and the sender user identifier carried in the shared information, and save the second shared data based on the recipient user identifier and the sender user identifier. Simultaneously, a second data identifier corresponding to the second shared data is generated and simultaneously sent to the super SIM cards of both the data receiving device and the data sending device for storage, so that both the data receiving device and the data sending device can view the second shared data through the second data identifier stored on the super SIM card.

[0178] In this way, after the first shared data is modified, the resulting second shared data can be directly uploaded to the server. Even if the roles of the receiving terminal device and the sending terminal device are reversed, data transmission can still be achieved. During data transmission, the server does not need to use complex encryption algorithms to encrypt the privacy data, and the second device does not need to use complex decryption algorithms to decrypt the encrypted data. The data encryption and decryption process is implemented through electronic identity certificates. During data transmission, the electronic identity certificates do not need to be transmitted. While ensuring the security of privacy data, the efficiency and flexibility of data transmission are improved.

[0179] Based on this, in some embodiments, such as Figure 11 As shown, prior to S230 above, the method may further include:

[0180] S610, The server receives the first shared data sent by the second device and the second user identifier of the second device, wherein the second user identifier is a user identifier obtained from the super SIM card of the second device;

[0181] S620, The server obtains the reception time of the first shared data and the second device information corresponding to the second user identifier;

[0182] S630. The server uses the second user identifier, the reception time of the first shared data, and the second device information to generate the first data identifier of the first shared data.

[0183] S640. The server sends a first data identifier to the second device so that the second device can obtain the first user identifier of the first device and send the first shared information to the first device corresponding to the first user identifier.

[0184] In some embodiments, for data that needs to be shared or transmitted, the user can upload such data to a server for storage. Before transmitting data to the first device (as the data receiving terminal device), the second device (as the data sender terminal device) sends the first shared data and the second user identifier of the second device to the server. After receiving the first shared data, the server can generate a first data identifier for the first shared data based on the second user identifier, the reception time of the first shared data, and the second device information. The server then sends the first data identifier to the second device, which stores the first data identifier in its own Super SIM card's storage folder for use in obtaining the first user identifier of the first device and sending the first shared information to the first device corresponding to the first user identifier.

[0185] In some embodiments, users can view the shared data that has been uploaded to the server and saved through the front-end access interface corresponding to the storage folder of the Super SIM card, and trigger subsequent operations to select the recipient user identifier and the data sending identifier by receiving user input on the front-end access interface.

[0186] In this way, data identifiers are generated by the server, and shared data is transmitted based on these identifiers. The server does not need to use complex encryption algorithms to encrypt private data, and the first device does not need to use complex decryption algorithms to decrypt encrypted data. The data encryption and decryption process is implemented through electronic identity certificates. During data transmission, the electronic identity certificates do not need to be transmitted, thus improving data transmission efficiency and flexibility while ensuring the security of private data.

[0187] In the embodiments provided in this application, for data that needs to be shared, users can upload the data to be shared to the server through the sending terminal device. The server saves the data, generates a unique identifier corresponding to the data, and sends the unique identifier to the Super SIM card of the sending terminal device for storage. When data transmission is required, the user can select the user identifier (e.g., user number) to be shared in the Super SIM card, and send the unique identifier of the data to be shared stored in the Super SIM card to the receiving terminal device via SMS through the core network. The core network sends the SMS to the receiving terminal device, and at the same time sends the receiving user identifier and the unique identifier in the SMS to the server.

[0188] The server determines the corresponding electronic identity certificate based on the recipient's user identifier and encrypts the data to be transmitted based on this certificate. Upon receiving the data-sharing SMS, the receiving terminal device determines the data reception and display method based on its current usage status and generates a data retrieval request based on the user identifier stored in its Super SIM card. This request is then sent to the server to retrieve the shared data. In response to the received data retrieval request, the server authenticates the requester and sends the encrypted data to the receiving terminal device. The receiving device decrypts the encrypted data using the electronic identity certificate stored in its Super SIM card, obtaining and displaying the shared data.

[0189] The data transmission method provided in this application embodiment uses an electronic identity certificate stored in the Super SIM card and a server corresponding to the Super SIM card. The receiving terminal device and the sending terminal device do not need to install additional encryption and decryption software, which greatly improves the data transmission efficiency. Moreover, the data encryption and decryption rely on the electronic identity certificate stored on the Super SIM card of the terminal device. The electronic identity certificate will not be transmitted in the Internet space during the data transmission process, thereby greatly improving the security of the transmitted data.
