Description

Data sharing methods, devices, equipment, systems and storage media

[0001] This application claims priority to Chinese Patent Application No. 202411759926.9, filed on November 29, 2024, entitled “Data Sharing Method, Apparatus, Device, System and Storage Medium”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to data sharing methods, apparatus, devices, systems and storage media. Background Technology

[0003] In scenarios involving multiple devices sharing data, it's necessary to share data from one device to at least another device. For example, a teacher prepares teaching materials on their personal device and then shares these materials to a large screen in the classroom for instruction.

[0004] In related technologies, taking data sharing between two devices as an example, one method is to transfer data from one device to another using a USB flash drive. Here, USB flash drive is short for Universal Serial Bus Flash Disk. Another method involves logging into communication software or a cloud drive on both devices. Data can then be transferred from one device to the other via the communication software, or one device can upload data to the cloud drive, and the other device can download it from the cloud drive.

[0005] However, all of the methods mentioned above require cumbersome operating procedures. Furthermore, using a USB flash drive makes it easy to lose or misplace the drive; using communication software can easily expose personal privacy; and using cloud storage has limitations on data size. Summary of the Invention

[0006] This application provides a data sharing method, apparatus, device, system, and storage medium for achieving rapid data sharing, solving the problem of complex operations during data sharing, and is not limited by distance, physical isolation, data volume, etc.

[0007] Firstly, a data sharing method is provided. Taking a first device executing the method as an example, the method includes: obtaining device information of a second device through an information carrier, wherein the information carrier is a medium carrying information, and the device information of the second device includes information required to establish a network connection with the second device; establishing a network connection between the first device and the second device based on the device information of the second device, so that the first device and the second device can communicate with each other through the network connection, wherein the network type of the network connection includes a local area network, a metropolitan area network, or a wide area network; and sharing data with the second device through the network connection.

[0008] This method enables the first and second devices to communicate and share data via a network connection. This communication eliminates the need for data copying or account login, making it convenient and easy to implement, and improving data sharing efficiency. Since the network type can be LAN, MAN, or WAN, data sharing through this network connection is not limited by distance, physical isolation, or data volume, enabling long-distance data sharing. Furthermore, device information is obtained through an information carrier, which is simple and convenient to use. This information includes the necessary data to establish a network connection with the second device, and network formation is automatic based on this information, eliminating the need for complex network configuration steps and resulting in rapid device networking.

[0009] In one possible implementation, the information carrier is a screen projector. The method by which the first device obtains the device information of the second device through the information carrier includes: the first device detecting that the screen projector has been inserted, and reading the device information of the second device stored in the screen projector. Thus, the screen projector enables rapid acquisition of device information, thereby achieving rapid networking between devices.

[0010] In one possible implementation, the information carrier is a near field communication (NFC) radio frequency signal. The first device obtains the device information of the second device through the information carrier by acquiring the device information of the second device from the NFC radio frequency signal. Thus, NFC enables rapid acquisition of device information, thereby facilitating rapid networking between devices.

[0011] In one possible implementation, the information carrier is a subsonic ultrasonic signal. The method by which the first device obtains the device information of the second device through the information carrier includes: the first device obtaining the device information of the second device from the subsonic ultrasonic signal. Therefore, subsonic ultrasonic signals enable rapid acquisition of device information, thereby achieving rapid networking between devices.

[0012] In summary, by using different information carriers, device information can be obtained flexibly, increasing the flexibility of rapid networking between devices.

[0013] In one possible implementation, the device information includes one or more of the following: device name, device address, network identifier, or network access password.

[0014] In one possible implementation, a first device contains first data, and a second device is granted first read / write permissions to the first data. The method by which the first device shares data with the second device via a network connection includes: upon receiving a first instruction from the second device to read the first data, the first device sends the first data to the second device via the network connection. This enables the first device to share the first data on its own device with the second device. In this case, the second device reads the first data on the first device in real time, without storing the first data locally on the second device, thus reducing the storage requirements on the second device.

[0015] In one possible implementation, after the first device sends first data to the second device via a network connection, the first device and the second device also synchronize their modification operations on the first data via the network connection. The network connection maintains communication between the first and second devices; therefore, the second device's modification operations on the first data can be sent to the first device in real time via the network connection, allowing the first device to synchronously modify the first data based on the received modification operations. After modifying the first data, the first device can also synchronize the modified first data to the second device in real time via the network connection. This simplifies the data synchronization process, eliminating the need for cumbersome operational steps.

[0016] In one possible implementation, the first device can encrypt the first data, so that the second device can only send the first command to the first device after completing the decryption and authentication of the first data. Thus, encryption can improve the security of data sharing.

[0017] In one possible implementation, the first device has a first space for storing data shared with the second device, and the second device is granted second read / write permissions to the first space. Another way for the first device to share data with the second device via a network connection includes: upon receiving a second instruction from the second device to read the first space, the first device sends the data in the first space to the second device via the network connection. Thus, data sharing is achieved by sharing space. In this case, the second device backs up and stores the first data shared by the first device; the locally stored first data allows the second device to quickly read or modify it, resulting in a faster response compared to real-time reading from the first device.

[0018] In one possible implementation, the second device includes a second space for storing data shared by the first device to the second device. After sending data from the first space to the second device via a network connection, the first device also synchronizes changes in the data in the first space with changes in the data in the second space via the network connection. The network connection maintains communication between the first and second devices; therefore, modifications made by the first device to the data in the first space are synchronized to the second device, enabling the second device to simultaneously modify the data in the second space; similarly, modifications made by the second device to the data in the second space are synchronized to the first device, enabling the first device to simultaneously modify the data in the first space. Thus, data synchronization is achieved through spatial synchronization, ensuring consistency between the data in the first space and the data in the second space.

[0019] In one possible implementation, the first device can encrypt the first space, so that the second device can only send the second command to the first device after completing the decryption and authentication of the first space. Thus, encryption can improve the security of data sharing.

[0020] In one possible implementation, the first device stores a sharing record of data sharing with the second device; therefore, after the first device shares data with the second device via a network connection, the method further includes: based on the sharing record, sharing data with the second device again via a network connection. This allows for faster and more convenient data sharing the next time data sharing is performed after one network setup is completed.

Taking the execution of the method by a second device as an example, the method includes: the second device transmitting its device information through an information carrier, where the information carrier is a medium carrying information, and the device information includes information required to establish a network connection with the second device; the second device accepting a network connection established between the first device and the second device based on the device information of the second device, so that the second device and the first device can communicate with each other through the network connection, where the first device is the device that obtains the device information of the second device, and the network type of the network connection includes a local area network, a metropolitan area network, or a wide area network; and the second device sharing data with the first device through the network connection.

[0022] In one possible implementation, the information carrier is a screen projector, and the method by which the second device transmits its device information through the information carrier includes: the second device detects that the second device is inserted into the screen projector, stores the device information of the second device in the screen projector, so that the first device can obtain the device information of the second device through the screen projector.

[0023] In one possible implementation, the information carrier is an NFC radio frequency signal, and the second device transmits its device information via the information carrier in the following manner: the second device broadcasts its device information via the NFC radio frequency signal so that the first device can obtain the device information of the second device via the NFC radio frequency signal.

[0024] In one possible implementation, the information carrier is a subsonic signal, and the method by which the second device transmits its device information through the information carrier includes: the second device broadcasting its device information through the subsonic signal so that the first device can obtain the device information of the second device through the subsonic signal.

[0079] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0080] In data sharing scenarios, how to quickly share data from one device to another is a pressing issue. Current technologies all require cumbersome steps. For example, USB flash drive sharing requires copying data from one device to a USB flash drive, and then copying the data from the USB flash drive to another device. Communication software or cloud storage sharing methods require logging into accounts on both devices, involving tedious authentication processes.

[0081] This application provides a data sharing method that enables simple and easy-to-operate data sharing. Figure 1 is a schematic diagram of an implementation environment provided by this application embodiment. As shown in Figure 1, the implementation environment includes one or more first devices 101 and one or more second devices 102. Each first device 101 can share data with one or more second devices 102. For example, any first device 101 can send data from that first device 101 to one or more second devices 102. Each second device 102 can share data from one or more first devices 101. For example, any second device 102 can receive data sent by one first device 101, or receive data sent by multiple first devices 101 respectively. Thus, one or more second devices 102 can receive and display data from one or more first devices 101, achieving data sharing.

[0082] This application does not limit the device type of the first device 101 or the second device 102. Optionally, both the first device 101 and the second device 102 can be terminals. For example, a terminal can be any electronic product that can interact with a user through one or more methods such as a keyboard, touchpad, touch screen, remote control, voice interaction, or handwriting device, such as a personal computer (PC), mobile phone, camera, printer, personal digital assistant (PDA), wearable device, pocket PC (PPC), tablet computer, or smart display terminal, etc.

[0083] Among them, the intelligent display terminal can be a large-screen terminal, which is a device that uses a large screen as a display terminal, also known as a large-screen device, used to intuitively display various data, videos, pictures, and other content. A large-screen terminal may include a signal source input section, a large-screen display, and a central control system. The central control system connects the signal source and the large-screen display, realizing signal switching and display functions. The large-screen display can be a light-emitting diode (LED) display or a liquid crystal display (LCD), etc. In one possible scenario, because a large-screen terminal is primarily a display device, it may not include high-performance processors or controllers, thus preventing the installation and use of communication software and other applications.

[0084] The method provided in this application can be applied to any scenario requiring data sharing, such as office or educational scenarios. In an office setting, staff typically prepare meeting materials on their personal devices (e.g., computers or mobile phones). When a meeting is needed, they share the prepared materials on their personal devices to a large-screen terminal in the conference room for presentation. In an educational setting, teachers prepare teaching materials on their personal devices. When a lesson is needed, they share the teaching materials on their personal devices to a large-screen terminal in the classroom for instruction.

[0085] For example, taking an educational scenario, Figure 2 is a schematic diagram of another implementation environment provided by an embodiment of this application. As shown in Figure 2, tablet computer 1 is located in teacher's office 1, large-screen terminal A is located in classroom 1, large-screen terminal B is located in classroom 2, and mobile phone 1 is located in classroom 2. Tablet computer 1 and mobile phone 1 correspond to the first device 101 in Figure 1, and large-screen terminal A and large-screen terminal B correspond to the second device 102 in Figure 1. Tablet computer 1 can share data with large-screen terminal A and / or large-screen terminal B, and mobile phone 1 can also share data with large-screen terminal A and / or large-screen terminal B. Large-screen terminal A can share data from tablet computer 1 and / or mobile phone 1, and large-screen terminal B can also share data from tablet computer 1 and / or mobile phone 1.

[0086] Referring to Figure 3, taking the interaction between the first device and the second device as an example, Figure 3 is a flowchart of a data sharing method provided by an embodiment of this application. The first device can be the first device 101 in Figure 1, and the second device can be the second device 102 in Figure 1; alternatively, the first device can be a tablet computer 1 or a mobile phone 1 in Figure 2, and the second device can be a large-screen terminal A or a large-screen terminal B in Figure 2. As shown in Figure 3, this data sharing method includes, but is not limited to, the following steps 301-304.

[0087] Step 301: The second device transmits its device information via an information carrier.

[0088] In this embodiment, the information carrier is a medium for carrying information. This information carrier is used to quickly obtain information, for example, by allowing information to be obtained without logging in or entering a password, thus improving the convenience of accessing device information. The information carrier can be a tangible or intangible carrier. For example, information carriers include, but are not limited to, tangible carriers such as USB flash drives or screen projectors, and intangible carriers such as NFC radio frequency signals, sub-ultrasonic signals, infrared signals, or Bluetooth signals. The information carrier does not include wired or wireless networks because when the first device and the second device first share data, they have not yet established a network connection, and therefore data transmission cannot be performed via the network. Furthermore, the information carrier does not include applications such as communication software or file transfer software, because such applications require cumbersome operations such as logging in or adding friends before information can be transmitted.

[0089] Optionally, device information refers to the information required for networking between devices, where networking refers to connecting devices to form a network. Networking the first device with the second device can refer to establishing a network connection between the first device and the second device. In this embodiment, the device information of the second device is the information required to establish a network connection with the second device. For example, device information includes one or more of the following: device name, device address, network identifier, or network access password. The device address is information that indicates the device's location, the network identifier is the identifier of the network the device is located in, and the network access password is the authentication password for the device to access the network it is located in. For example, the device address includes, but is not limited to, one or more of the following: medium access control (MAC) address or internet protocol (IP) address.

[0090] In one possible implementation, the second device is located within a local area network (LAN). A LAN is a network of devices and their peripherals connected via a transmission medium within a relatively small geographical area. This smaller geographical area can be, for example, the interior of an office, a building, a campus, or a company. Transmission media within a LAN include, but are not limited to, Ethernet, wireless networks, and fiber optic networks. Wireless networks can be, for example, wireless fidelity (Wi-Fi) networks or wireless local area networks (WLANs). Devices within a LAN typically share the same network protocols and communication standards, thereby ensuring efficient data transmission within the LAN.

[0091] Taking the local area network where the second device is located as an example of communication via a Wi-Fi network, the network identifier of the second device can be a Wi-Fi service set identifier (SSID), and the network access password of the second device can be the authentication password for the second device to access the local area network. This authentication password can be a Wi-Fi protected access (Wi-Fi WPA) password.

[0092] Step 302: The first device obtains the device information of the second device through the information carrier.

[0093] When the second device transmits its device information via an information carrier, the first device can obtain the device information of the second device through that information carrier. Alternatively, the second device can also obtain the device information of the second device through other means, such as manually inputting the device information.

[0094] This application embodiment uses three methods, namely a screen projector, NFC radio frequency signal, and subsonic signal, as examples to illustrate how the first device obtains device information of the second device.

[0095] Method 1: The first device obtains the device information of the second device through a screen mirroring device.

[0096] A screen mirroring device is a device that can wirelessly or wiredly transmit the screen content of one device to another, allowing multiple devices to display the same image. For example, a screen mirroring device can connect to a device via a universal serial bus (USB) interface and use wireless transmission technology to transmit the screen content of one device to another in real time. The screen mirroring device can be a small, wired projection adapter.

[0097] In one possible implementation, the second device detects that a screen projector has been inserted and stores the device information of the second device in the screen projector. Then, the screen projector is inserted into the first device, which detects that a screen projector has been inserted and reads the device information of the second device stored in the screen projector. Thus, device information can be quickly obtained through the screen projector.

[0098] For example, refer to Figure 4, which illustrates the transmission of device information. When the projector is inserted into the second device, it automatically acquires the device information of the second device. During this acquisition process, as shown in Figure 4, the screen of the second device displays "Acquiring device information." In one possible implementation, the projector has a built-in device information acquisition program. When the projector is inserted into the second device, it automatically starts the program, automatically acquiring the device information of the second device, which is then stored in the projector.

[0099] Optionally, while the screen displays "Retrieving Device Information," the second device cannot perform other operations to avoid interfering with the acquisition of device information. After the projector completes acquiring the device information of the second device, the screen of the second device stops displaying "Retrieving Device Information," and the second device resumes normal operation. After the projector completes acquiring the device information of the second device, for example, after the screen of the second device stops displaying "Retrieving Device Information," the projector is unplugged from the device. Then, the projector is plugged into the first device, and the first device reads the device information of the second device stored in the projector, thereby obtaining the device information of the second device. In one possible implementation, the projector has a built-in device information reading program. When the projector is plugged into the first device, the projector can automatically start the device information reading program to read the device information of the second device.

[0100] In addition to storing the device information of the second device, the screen mirroring device may also store device information of at least one other device. In this case, the first device can read the device information of all devices stored in the screen mirroring device, and then select the device information of the second device from the read device information. For example, as shown in Figure 4, after the screen mirroring device is inserted into the first device, if the first device reads the device information of multiple devices from the screen mirroring device, a pop-up window will display the device identifiers of multiple devices on the screen of the first device. Each device identifier corresponds to the device information of one device, and the user can select the second device to be paired with in the network from among the multiple devices. For example, the user can select the second device by clicking on any device identifier on the screen, triggering the first device to perform network pairing with the second device based on the device information of the second device.

[0101] Method 2: The first device obtains the device information of the second device through NFC radio frequency signals.

[0102] NFC, also known as Near Field Communication, is a short-range, high-frequency wireless communication technology used for contactless, point-to-point data transmission between devices. In one possible implementation, a second device broadcasts its device information via an NFC radio frequency signal; the first device then retrieves this broadcast device information from the NFC radio frequency signal. Thus, NFC enables rapid acquisition of device information.

[0103] For example, refer to Figure 5, which illustrates the transmission of device information. Both the first and second devices have built-in NFC functionality. Enabling the NFC function on the second device encodes its device information, required for network configuration, as a broadcast signal into the NFC radio frequency signal. This NFC radio frequency signal propagates through the air near the second device. Enabling the NFC function on the first device, and bringing it close to the second device, allows the first device to receive the NFC radio frequency signal propagated by the second device. The device information of the second device is obtained by parsing the NFC radio frequency signal and saved locally on the first device. In one possible scenario, parsing the NFC radio frequency signal may retrieve device information from multiple devices. As shown in Figure 5, a pop-up window on the first device's screen displays device identifiers for multiple devices, with each identifier corresponding to the device information of one device. The user then selects the second device from among these devices to form a network pair.

[0104] Method 3: Obtain the equipment information of the second device through sub-ultrasound.

[0105] Subsonic signals refer to signals with frequencies between 18-20 kHz, which can transmit data. In one possible implementation, the second device broadcasts its own device information via a subsonic signal; the first device then retrieves this broadcast device information from the subsonic signal. Thus, the subsonic function enables rapid acquisition of device information.

[0106] For example, both the first and second devices have built-in sub-ultrasonic functionality. Enabling the sub-ultrasonic function on the second device encodes its device information, required for network distribution, into the sub-ultrasonic signal as a broadcast signal. Enabling the sub-ultrasonic function on the first device allows it to receive the sub-ultrasonic signal transmitted by the second device. The device information of the second device is obtained by parsing the sub-ultrasonic signal and saved locally on the first device. In one possible scenario, parsing the sub-ultrasonic signal may yield device information for multiple devices. A pop-up window on the first device displays the device identifiers of these multiple devices, with each device identifier corresponding to the device information of one device. The user then selects the second device from among these devices for network pairing.

[0107] Step 303: The first device establishes a network connection between the first device and the second device based on the device information of the second device, so that the first device and the second device can communicate with each other through the network connection.

[0108] This application does not limit the networking method; it only requires that the first device and the second device communicate with each other via a network connection. The network type of the network connection includes a local area network (LAN), a metropolitan area network (MAN), or a wide area network (WAN). Taking a LAN as an example, the first device and the second device communicate with each other via a LAN. Optionally, the first device and the second device communicate with each other through the same LAN, that is, the first device and the second device are located in the same LAN; or, the first device and the second device communicate with each other through their respective LANs, that is, the first device is located in a first LAN, the second device is located in a second LAN, and the first LAN and the second LAN are interconnected.

[0109] In this embodiment, since the device information of the second device includes the information required to establish a network connection with the second device, the network connection between the first device and the second device can be established upon obtaining the device information of the second device. Optionally, both the first device and the second device are connected to the network. The device information of the second device includes the device address of the second device, thereby enabling the first device to communicate with the second device through the device address and complete the establishment of the network connection. Alternatively, only the second device is connected to the network. The device information of the second device includes the device address, network identifier, and network access password of the second device. The first device accesses the network where the second device is located based on the network identifier and network access password, and then communicates with the second device through the device address of the second device to complete the establishment of the network connection. For example, the network where the second device is located can be a local area network (LAN) connected to the second device. This LAN can be a WiFi network connected to the second device, or a hotspot network created by the second device.

[0110] In one possible implementation, the method by which the first device establishes a network connection with the second device based on the device information of the second device includes: the first device sending a connection request to the second device based on the device information of the second device; the second device accepting the connection request and returning a response to the connection request to the first device. Thus, a network connection is established between the first device and the second device, completing the networking between the first device and the second device.

[0111] After the first and second devices complete their initial network setup, they maintain communication through this network connection. That is, during data sharing, the first and second devices can maintain data transmission without needing to re-establish a network connection. Subsequently, when the first and second devices share data again, since the first device stores the device information of the second device from the previous network setup, as long as the second device has not updated this information, the first device can directly establish a network with the second device based on the locally stored device information, without needing to obtain the second device's device information again through an information carrier.

[0112] Step 304: The first device and the second device share data through a network connection.

[0113] After the first device and the second device establish a network connection, the first device can share data with the second device via the network connection, and similarly, the second device can share data with the first device via the network connection. In this embodiment, the shared data can refer to files, and the file types include, but are not limited to, videos, images, audio, or text. The files can be stored in folders.

[0114] In one possible implementation, after the first device and the second device share data via a network connection, the second device can save a sharing record of the data sharing with the first device, and the first device can also save a sharing record of the data sharing with the second device. The sharing record indicates the established network connection, and optionally, the sharing record may include at least one of device information, shared location, or shared content. Therefore, based on the sharing record, the first device can again share data with the second device via the network connection, achieving rapid data sharing without needing to re-acquire device information.

[0115] Optionally, a shared record can correspond to a user, meaning a user can quickly find their previous data-sharing record by authenticating their identity. In this case, the first device can obtain the shared record of data sharing with the second device through authentication, and then, based on this shared record, share data with the second device again through the established network connection. The second device can also obtain the shared record of data sharing with the first device through authentication, and can also share data with the first device again through the same network connection based on this shared record. This allows for faster and more convenient data sharing after the network setup is completed, with authentication enabled for subsequent data sharing. Authentication methods include, but are not limited to, facial recognition, fingerprint authentication, password authentication, or SMS authentication.

[0116] Taking the sharing of data on the first device to the second device as an example, the sharing methods include, but are not limited to, the following two.

[0117] The first sharing method involves achieving data sharing between the first and second devices through network mapping.

[0118] In this sharing method, the first device contains first data, and the second device is granted first read / write permissions to the first data. The method by which the first device shares data with the second device via a network connection includes: upon receiving a first instruction from the second device to read the first data, the first device sends the first data to the second device via the network connection. For example, the first device grants the second device first read / write permissions to the first data on the first device; upon obtaining the first read / write permissions, the second device sends a first instruction to the first device to read the first data based on the first read / write permissions; upon receiving the first instruction from the second device to read the first data, the first device sends the first data to the second device via the network connection; and the second device receives the first data sent by the first device based on the first instruction via the network connection.

[0119] This enables the first device to share its first data with the second device. In this scenario, the second device reads the first data from the first device in real time via network mapping, without storing the first data locally on the second device, thus reducing the storage requirements on the second device.

[0120] In one possible implementation, after the first device sends first data to the second device via a network connection, the first device and the second device also synchronize modification operations on the first data via the network connection. Modification operations include, but are not limited to, adding, deleting, or modifying data. Since the network connection maintains communication between the first and second devices, the second device's modification operations on the first data can be sent to the first device via the network connection, allowing the first device to synchronously modify the first data based on the received modification operations. After modifying the first data, the first device can also synchronize the modified first data to the second device in real time via the network connection. This simplifies the data synchronization process, eliminating the need for cumbersome operational steps.

[0121] In this embodiment, the first device can encrypt the first data so that the second device can only send the first instruction to the first device after completing the decryption and authentication of the first data. For example, the second device performs decryption and authentication of the first data based on first read / write permissions; after completing the decryption and authentication of the first data, it sends the first instruction to the first device. Thus, encryption improves the security of data sharing. Optionally, encryption methods include, but are not limited to, personal identification numbers (PINs), facial recognition, voiceprint recognition, or fingerprint recognition.

[0122] For example, Figures 6 and 7 illustrate a method of data sharing via network mapping. In this example, the screen of the first device displays folder 1, which is the shared folder to be shared. Folder 1 contains the files to be shared, i.e., the first data. When the first device is interconnected with multiple devices via a network connection (i.e., all devices are on the same network connection as the first device, such as devices 1, 2, and 3 as shown in Figure 7), the first device can choose which device to share folder 1 with. In Figure 7, the first device selects to share folder 1 with device 1, so device 1 corresponds to the second device. Optionally, the first device can encrypt folder 1.

[0123] After the first device selects folder 1 for sharing, it grants the second device read and write permissions for folder 1. This allows the second device to read the data within folder 1 in real time via a network connection. The shared folder from the first device can then be displayed on the second device's screen, and this shared folder includes the identifier of folder 1 selected by the first device. Since the shared data is not stored locally on the second device, the shared folder from the first device does not include the data from folder 1. Therefore, as shown in Figure 6, the shared folders of the first and second devices are connected via a network mapping module, which enables real-time data transmission between the shared folders of the first and second devices.

[0124] For example, when the second device selects the identifier of folder 1 in the shared folder, it triggers the real-time transmission of data within folder 1 from the first device to the second device, achieving real-time data sharing. This allows the second device to display the shared data on the first device in real time. If the first device encrypts folder 1, the second device needs to decrypt and authenticate folder 1 before triggering shared data transmission, or before displaying shared data. The second device may also share data with other devices. As shown in Figure 7, the second device's screen also displays a shared folder from a third device, which contains folder identifiers or file identifiers shared by the third device to the second device.

[0125] Optionally, the second device may save sharing records, such as the shared folders of the first device. A shared folder can correspond to one or more user identities. In this case, when the second device wants to share data again, it can directly access the saved shared folder corresponding to that user identity through authentication. Since this shared folder contains the folder or file identifiers shared by the first device to the second device, it can quickly access the shared data on the first device without needing to re-establish the network. For example, after authentication, the second device may ask the user if they want to open the corresponding shared folder. After the user confirms, the second device's screen will automatically display the user's corresponding shared folder.

[0126] Therefore, by using network mapping, shared data on the first device can be quickly obtained on the second device and used as if it were local data on the second device. Modifications to the shared data can be synchronized back to the first device in real time, greatly reducing the hassle of users having to copy materials back and forth.

[0127] The second sharing method is to achieve data sharing between the first and second devices through synchronization space.

[0128] In this second sharing method, the first device has a first space for storing data shared with the second device, and the second device is granted second read / write permissions to the first space. The method by which the first device shares data with the second device via a network connection includes: upon receiving a second instruction from the second device to read the first space, the first device sends data from the first space to the second device via the network connection. For example, the first device grants the second device second read / write permissions to the first device for the first space on the first device, where the first space is used to store data shared by the first device to the second device; upon obtaining the second read / write permissions to the first space on the first device, the second device sends a second instruction to the first device to read the first space based on the second read / write permissions; upon receiving the second instruction from the second device to read the first space, the second device sends data from the first space to the second device via the network connection; and the second device receives data from the first device sent by the first device based on the second instruction via the network connection.

[0129] Therefore, data sharing is achieved through shared space. In this scenario, the second device backs up and stores the first data shared by the first device. The locally stored first data allows the second device to quickly read or modify it, resulting in a faster response compared to reading from the first device in real time.

[0130] In one possible implementation, the second device includes a second space for storing data shared by the first device to the second device. For example, after the second device receives data in the first space sent by the first device based on a second instruction via a network connection, it stores the data in the first space into the second space on the second device.

[0131] Optionally, the first device is also connected to the second device via a network to synchronize data changes in the first space with data changes in the second space. Since the network connection maintains communication between the first and second devices, modifications made by the first device to the data in the first space can be synchronized to the second device, enabling the second device to simultaneously modify the data in the second space, and vice versa, ensuring consistency between the data in the first and second spaces.

[0132] In this embodiment, the first device can encrypt the first space so that the second device can only send the second instruction to the first device after completing the decryption authentication of the first space. For example, the second device performs decryption authentication of the first space based on second read / write permissions; after completing the decryption authentication of the first space, it sends the second instruction to the first device. Thus, encryption can improve the security of data sharing.

[0133] For example, Figures 8 and 9 illustrate a method of data sharing via a synchronization space. The screen of the first device displays the synchronization space of the second device (corresponding to the first space). The synchronization space file of the second device includes folders 1 and 2 that the first device intends to share with the second device. When the first device communicates with multiple devices via a network connection, the screen of the first device may also display the synchronization spaces of other devices, used to store data shared by the first device with these other devices. Optionally, the first device may encrypt the synchronization space of the second device.

[0134] In one possible scenario, both the first and second devices have synchronization software installed, enabling data synchronization between the first and second storage spaces. For example, when the first and second devices complete network formation, both devices will automatically download the synchronization software; alternatively, the user can download and install the software beforehand from a designated location. Within the synchronization software, the first device selects a folder as the synchronization space for data sharing with the second device and grants the second device read and write permissions to that space. In this case, the second device's synchronization software will also create a folder as the first device's synchronization space.

[0135] The first device stores shared folders 1 and 2 in a first space. The synchronization software periodically monitors changes in the first space on the first device and synchronizes these changes to the second space on the second device. Since the data in the first and second spaces is synchronized, the data shared by the first device to the second device is stored locally on the second device, allowing the second device to display the shared data on the first device in real time. Therefore, as shown in Figure 8, the first space of the first device and the second space of the second device are connected through a space synchronization module, which enables real-time data transmission between them.

[0136] If the first device encrypts the first space, the second device needs to decrypt and authenticate the first space before space synchronization can be triggered, or the shared data in the second space can be displayed only after the first space is decrypted and authenticated. The second device may also share data with other devices. As shown in Figure 9, the screen of the second device also displays the synchronization space of the third device, which includes data shared by the third device to the second device.

[0137] Optionally, the second device may store sharing records, such as the synchronization space of the first device. One synchronization space can correspond to one or more user identities. In this case, when the second device wants to share data again, it can directly access the saved synchronization space corresponding to that user identity through authentication. Since the synchronization space contains the data shared by the first device to the second device, the shared data can be quickly accessed based on this synchronization space without needing to re-establish the network. For example, the second device, after authentication, asks the user whether to open the corresponding synchronization space. After the user confirms, the user's synchronization space will automatically pop up on the second device's screen.

[0138] Therefore, by establishing a synchronization space between the first and second devices, rapid data sharing can be achieved, and any modifications made within the synchronization space will be promptly synchronized to the data copy stored in the synchronization space, greatly reducing the tedious process of users copying materials back and forth.

[0139] The above describes how the first device shares data from the first device to the second device. The method by which the second device shares data from the second device to the first device is similar to the method described above, and will be briefly introduced in this application embodiment.

[0140] In one possible implementation, the second device shares data with the first device via a network connection, including: the second device granting the first device third read / write permissions to second data on the second device; the first device, having obtained the third read / write permissions, sending a third instruction to the second device to read the second data based on those permissions; the second device, upon receiving the third instruction from the first device, sending the second data to the first device via the network connection; and the second device receiving the second data sent by the first device based on the third instruction via the network connection. Optionally, after sending the second data to the first device via the network connection, the second device also synchronizes modification operations on the second data with the first device via the network connection. The second device can encrypt the second data so that the first device can only send the third instruction to the second device after completing decryption authentication of the second data. That is, the first device can share data with the second device, and the second device can also share data with the first device, improving the flexibility and feasibility of data sharing.

[0141] In another possible implementation, the method by which the first device shares data with the second device via a network connection includes: the second device granting the first device a fourth read / write permission to a second space on the second device, the second space being used to store data shared by the second device to the first device; the first device, upon obtaining the fourth read / write permission to the second space on the second device, sending a fourth instruction to the second device to read the second space based on the fourth read / write permission; upon receiving the fourth instruction from the first device to read the second space, the second device sending the data in the second space to the first device via the network connection; and the first device receiving the data in the second space sent by the second device based on the fourth instruction via the network connection. Optionally, the second device includes a first space for storing data shared by the second device to the first device; after sending the data in the second space to the first device via the network connection, the second device also synchronizes changes in the data in the second space with changes in the data in the first space via the network connection. The second device may also encrypt the second space so that the first device can only send the fourth instruction to the second device after completing decryption authentication of the second space.

[0142] In scenarios where a first device and a second device share data, the first space on the first device is used to store data shared by the first device to the second device, and also to store data shared by the second device to the first device; similarly, the second space on the second device is used to store data shared by the first device to the second device, and also to store data shared by the second device to the first device. That is, the first device can share data with the second device through the first space, and the second device can also share data with the first device through the second space, thus improving the flexibility and feasibility of data sharing.

[0143] In summary, the data sharing method provided in this application enables rapid networking between a first device and a second device via information carriers such as screen projectors, NFC radio frequency signals, or subsonic signals, greatly increasing the convenience of networking between the two devices. Rapid data sharing and synchronization are achieved through network mapping or the creation of synchronization spaces. This solves the problem of quickly sharing or synchronizing files from personal devices to large-screen terminals, significantly improving the convenience of material sharing and display. Furthermore, the shared data can be optionally encrypted for privacy protection.

[0144] The data sharing method of this application embodiment has been described above. Corresponding to the above method, this application embodiment also provides a data sharing device. Figure 10 is a schematic diagram of the structure of a data sharing device provided in this application embodiment. This device is applied to a first device, which is the first device in the method shown in Figure 3 above. Based on the multiple modules shown in Figure 10, the data sharing device shown in Figure 10 can perform all or part of the operations performed by the first device. It should be understood that the device may include more additional modules than the modules shown or omit some of the modules shown.

[0155] In one possible implementation, the device further includes a second encryption module for encrypting the first space, so that the second device can send a second instruction to the first device after completing the decryption and authentication of the first space.

[0156] In one possible implementation, the first device stores a sharing record of data sharing with the second device; the data sharing module 1003 is also used to share data with the second device again via a network connection based on the sharing record.

[0157] Figure 11 is a schematic diagram of another data sharing device provided in an embodiment of this application. This device is applied to a second device, which is the second device in the method shown in Figure 3 above. Based on the multiple modules shown in Figure 11, the data sharing device shown in Figure 11 can perform all or part of the operations performed by the second device. It should be understood that the device may include more additional modules than the modules shown or omit some of the modules shown, and this embodiment of the application does not impose any limitations on this.

[0158] As shown in Figure 11, the device includes: a transmission module 1101, used to transmit device information of a second device through an information carrier, the information carrier being a medium carrying information, the device information of the second device including information required to establish a network connection with the second device; a connection establishment module 1102, used to accept a network connection established between the first device and the second device by the first device based on the device information of the second device, so that the second device and the first device can communicate with each other through the network connection, the first device being the device that obtains the device information of the second device, and the network type of the network connection including a local area network, a metropolitan area network, or a wide area network; and a data sharing module 1103, used to share data with the first device through the network connection.

[0159] In one possible implementation, the information carrier is a screen projector, and the transmission module 1101 is used to store the device information of the second device in the screen projector when the insertion of the screen projector is detected, so that the first device can obtain the device information of the second device through the screen projector.

[0165] In one possible implementation, the data sharing module 1103 is used to send a second instruction to the first device to read the first space based on the second read / write permission when it obtains the second read / write permission to the first space on the first device. The first space stores data shared by the first device to the second device. The module also receives data in the first space sent by the first device based on the second instruction via a network connection.

[0166] In one possible implementation, the data sharing module 1103 is further configured to store data in the first space into a second space on the second device; the device also includes a second synchronization module, configured to synchronize data changes in the second space with data changes in the first space via a network connection between the first device and the second device.
