[0002] In recent years, there have been more and more forms of data interaction between different terminal devices, such as screen mirroring connections. In the scenario of screen mirroring connection, one terminal device saves its video, audio, and other data as multiple frames of data through screen recording, audio recording, etc., and then transmits the multiple frames of data to another terminal device through a wired connection or a wireless connection. The other terminal device can then parse the multiple frames of data to obtain the original video, audio, and other data, and then perform display or playback and other presentation operations on it. During the process of continuously transmitting a large amount of data between two terminal devices, the data may be intercepted by malicious applications, that is, the security of data interaction is relatively poor.

[0101] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0102] The terms used in the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The singular forms "a", "the" and "said" used in the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0103] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0104] In recent years, there have been more and more forms of data interaction between different terminal devices, such as screen mirroring connections. In the scenario of screen mirroring connection, a terminal device saves its video, audio and other data as multiple frames of data through screen recording, audio recording, etc., and then transmits it to another terminal device through wired or wireless connection. The other terminal device can parse the multiple frames of data to obtain the original video, audio and other data, and then perform display or playback and other display operations on it. During the continuous transmission of a large amount of data between two terminal devices, the data may be intercepted by malicious applications, that is, the security of data interaction is poor. If these data contain the user's call data, contacts, account passwords, etc., it may lead to the leakage of this information, seriously affecting the user's personal information security.

[0105] To ensure the security of data interaction, in related technologies, a terminal device encrypts the data before transmitting it, and the other terminal device decrypts the data after receiving it. However, the above encryption and decryption processes not only reduce the efficiency of data interaction, but also increase the computing load of the terminal device. Taking the scenario of screen mirroring connection as an example, the above encryption and decryption processes will greatly reduce the efficiency of video and audio transmission, causing problems such as video frame freezing or blurring, and audio freezing or distortion. Moreover, if the malicious application intercepting the interaction data has the ability to decrypt, it will continuously obtain and decrypt the interaction data, resulting in the continuous leakage of important information, which has a greater impact on data security.

[0106] Based on this, in a first aspect, at least one embodiment of the present disclosure provides a data interaction method. Please refer to the appendix Figure 1 , which shows the flow of the method, including step S101 and step S103.

[0107] Among them, this method can be applied to a first terminal device, and the first terminal performs screen mirroring interaction with a second terminal. The first terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA) handheld device, a computing device, a wearable device, etc. The first terminal device can be the data source in a data interaction scenario, that is, the side that sends data outward. For example, in the scenario of a smartphone casting the screen to a TV, the smartphone is the data source and the TV is the data destination.

[0108] It can be understood that this method can be executed by a specific application or a specific module of the first terminal device. For example, as Figure 2 , terminal A, as the first terminal device, has application C for data interaction. Application C can communicate and connect with other application programs such as application 1, application 2, application 3, etc., so as to obtain interactive data such as audio data and video data from other application programs, encapsulate these interactive data, and send them to terminal B as the second terminal device. Terminal B is the data destination of data interaction. It can receive the data sent by application C, decompose the encapsulated data, and at the same time can also reverse-control the application of terminal A, that is, send control instructions to application C, and then application C sends these control instructions to the corresponding application programs. These other application programs can be music application programs, video application programs, navigation application programs, social application programs, etc.

[0109] In step S101, key data in the interactive data is obtained, and the key data is encapsulated into M first data packets, where M is a natural number greater than 1.

[0110] Among them, the interactive data is the data targeted by data interaction, that is, the data sent by the first terminal device to the second terminal device. Taking the screen mirroring scenario as an example, the interactive data is data such as video and audio. The key data can be data related to user privacy or account security.

[0111] During the process of data interaction, the first terminal device can determine the interaction data and the application program to which the interaction data belongs according to the interaction control instruction, and obtain the interaction data from the application program to which the interaction data belongs, where the interaction control instruction is generated based on the user's operation on the first terminal device or the second terminal device. Taking the screen mirroring scenario as an example, after the first terminal device and the second terminal device establish a screen mirroring connection, the first terminal device will send the default screen to the second terminal device so that the second terminal device can display the default screen, which can be the current screen of the first terminal device, the desktop, or the dedicated initial screen of the screen mirroring program; Next, the user can operate on the first terminal device, then the first terminal device generates an interaction control instruction based on this operation, or operates on the above default screen displayed on the second terminal device, and the second terminal device generates an interaction control instruction based on this operation and sends the interaction control instruction to the first terminal device. The first terminal device obtains data such as the screen and audio from the corresponding application program according to the interaction control instruction. For example, if the interaction control instruction is to start a certain application program on the desktop, the first terminal device starts the application program and obtains the initial interface after the application program starts as the interaction data.

[0112] After the first terminal device obtains the interaction data, it can determine whether there is key data in the interaction data in the following way: First, determine whether there is data belonging to the preset key data list in the interaction data. Exemplarily, a preset key data list is pre-set in the first terminal device; Next, in the case where there is data belonging to the preset key data list in the interaction data, it is determined that there is key data in the interaction data, and it is determined that the data belonging to the preset key data list in the interaction data is the key data; In the case where there is no data in the preset key data list in the interaction data, it is determined that there is no key data in the interaction data.

[0113] In the case where there is key data in the interaction data, this step can be executed, that is, obtain the key data in the interaction data. Due to the influence of the transmission channel bandwidth, the key data cannot be directly transmitted to the second terminal device, so reference can be made to Appendix Figure 3 to encapsulate the key data into M first data packets.

[0114] In addition, it is also possible to obtain the non-key data in the interaction data, encapsulate the key data into multiple second data packets, and send the multiple second data packets to the second terminal device so that the second terminal device can parse and display the non-key data.

[0115] In the case where there is no key data in the interaction data, the interaction data can be encapsulated into multiple third data packets, and the multiple third data packets are sent to the second terminal device, so that the second terminal device can parse and display the interaction data.

[0116] In step S102, N first data packets among the M first data packets are encrypted, and the M first data packets are sequentially sent to the second terminal device, where N is greater than or equal to 1 and less than M.

[0117] Among them, the first data packets to be encrypted can be part of the M first data packets. Exemplarily, the encryption ratio K can be determined first according to the computing power p of the first terminal device and the quality parameter q of the data transmission link. The computing power p of the first terminal device can be used to represent the encryption speed of the first terminal device, and the quality parameter q of the data transmission link can be used to represent the packet loss rate. If the packet loss rate is too high, the encrypted first data packets may be lost, resulting in meaningless encryption. Taking the screen mirroring scenario as an example, the packet loss rate is extremely low, and the value of q is between 0.98 and 1. For example, K can be calculated according to the following formula: K = p * q; then, according to the M and the encryption ratio K, the encryption quantity N is determined. For example, N can be calculated according to the following formula: N = M * K; finally, the first N first data packets among the multiple first data packets are encrypted. Reference can be made to the appendix Figure 4 , after the key data is encapsulated into 4 first data packets, the first 3 first data packets are encrypted. It can be understood that the appendix Figure 4 is only an example. Generally, the encryption ratio K is between 20% and 30%.

[0118] In a possible embodiment, the first data packets can be encrypted in the manner as Figure 5 shown: The encryption identifier F, the encryption information I, and the first data packet are encrypted to obtain the encrypted first data packet, where the encryption identifier F is used for the second terminal device to determine the first data packet that has been encrypted from the multiple first data packets.

[0119] It can be understood that during the data interaction process, the first terminal device continuously obtains interaction data according to the interaction control instruction, and determines whether there is key data in the interaction data. If there is key data, some or all of the multiple first data packets obtained by encapsulating the key data are encrypted and sent to the second terminal device, and the multiple second data packets obtained by encapsulating the non-key data are directly sent to the second terminal device. If there is no key data, the multiple third data packets obtained by directly encapsulating the interaction data are sent to the second terminal device. The processing and sending order of the above interaction data can be determined according to the order of obtaining the interaction data.

[0120] In step S103, upon receiving the encrypted information returned by the second terminal device, it is determined whether to continue sending the interaction data according to the encrypted information, where the encrypted information is obtained by the second terminal device decrypting the first data packet that has been encrypted.

[0121] Among them, during the data interaction process, the second terminal device continuously receives the interaction data sent by the first terminal device in the form of data packets, and then processes the received interaction data in sequence, that is, processes the received data packets in sequence. Before processing the data packet, it can be checked whether the data packet has an encryption flag. If it does not have an encryption flag, the data packet is the second data packet, the third data packet, or the first data packet that has not been encrypted. If it has an encryption flag, the data packet is the first data packet that has been encrypted.

[0122] After receiving multiple second data packets sent by the first terminal device, the multiple second data packets can be parsed and processed in sequence according to the reception order to obtain the non-critical data, and the non-critical data can be displayed according to the display method of the non-critical data. Exemplarily, if the non-critical data is a picture, the image can be displayed; if the non-critical data is a video, the video can be played.

[0123] After receiving multiple third data packets sent by the first terminal device, the multiple third data packets can be parsed and processed in sequence according to the reception order to obtain the interaction data, and the interaction data can be displayed according to the display method of the interaction data. Exemplarily, if the interaction data is a picture, the image can be displayed; if the interaction data is a video, the video can be played.

[0124] After receiving multiple first data packets sent by the first terminal device, the first data packets with encryption flags among the multiple first data packets can be determined as the first data packets that have been encrypted, and then the N first data packets that have been encrypted are decrypted to obtain the encrypted information and the decrypted first data packets. Then, the multiple first data packets are parsed and processed in sequence according to the reception order to obtain the critical data, and the critical data is displayed according to the display method of the critical data. Exemplarily, if the critical data is a picture, the image can be displayed; if the critical data is a video, the video can be played; at the same time, the encrypted information can be sent to the first terminal device.

[0125] When the first terminal device receives the encrypted information returned by the second terminal device within a preset time period and the encrypted information passes the verification, it continues to send the interaction data, that is, it continues to send the key data and non-key data in the interaction data with key data in the form of data packets, as well as the interaction data without key data; otherwise (that is, when the first terminal device does not receive the encrypted information returned by the second terminal device within the preset time period, or when the first terminal device receives the encrypted information returned by the second terminal device within the preset time period but the encrypted information fails to pass the verification), it stops sending the interaction data, that is, it stops sending the key data and non-key data in the interaction data with key data, as well as the interaction data without key data. For example, in a screen mirroring scenario, it can stop screen mirroring and disconnect the screen mirroring connection with the second terminal device.

[0126] It can be understood that when the first terminal device does not receive the encrypted information returned by the second terminal device within the preset time period, or when the first terminal device receives the encrypted information returned by the second terminal device within the preset time period but the encrypted information fails to pass the verification, the first terminal device can also generate a prompt message, such as a text prompt message displayed on the display screen or an audio prompt message played by the speaker.

[0127] The present disclosure obtains the key data in the interaction data, encapsulates the key data into M first data packets, then encrypts N of the M first data packets, and sequentially sends the M first data packets to the second terminal device. Finally, it receives the encrypted information returned by the second terminal device and determines whether to continue sending the interaction data according to the encrypted information. Wherein, the encrypted information is obtained by the second terminal device decrypting the encrypted first data packet. Since N of the M first data packets encapsulating the key data in the interaction data are encrypted, after the M data packets are sent to the second terminal device, it can be determined whether the second terminal device has successfully decrypted the encrypted first data packet according to whether the second terminal device returns encrypted information that can pass the verification. Furthermore, it can be determined whether the data sent to the second terminal device is secure, and in the case of insecurity, stop sending the interaction data, thereby avoiding data leakage and ensuring data security.

[0128] In the present disclosure, some of the multiple first data packets obtained by encapsulation are encrypted, thereby reducing the computing load of the encryption process of the first terminal device and the computing load of the decryption process of the second terminal device, thus avoiding problems such as lag and disconnection. Moreover, the present disclosure further controls the subsequent data interaction of the first terminal device according to the decryption situation of the second terminal device for the encrypted first data packet, that is, continues the data interaction when the second terminal device successfully decrypts the encrypted first data packet, and stops the data interaction when the second terminal device fails to decrypt the encrypted first data packet, thereby avoiding the leakage of user information caused by the malicious application in the second terminal device being unable to decrypt the encrypted first data packet but still being able to obtain the unencrypted first data packet. Furthermore, the present disclosure encrypts the first N first data packets among the multiple first data packets, which can avoid the subsequent unencrypted data packets from being intercepted in the case of malicious application intercepting data, and maximally ensures data security.

[0129] In a second aspect, at least one embodiment of the present disclosure provides a data interaction method. Please refer to the appendix Figure 6 , which shows the flow of the method, including step S601 and step S503.

[0130] Among them, this method can be applied to a second terminal device. The second terminal device can be a television, a vehicle-mounted terminal, etc. The second terminal device can be the data destination in the data interaction scenario, that is, the receiving side. For example, in the scenario where a smartphone casts a screen to a television, the smartphone is the data source and the television is the data destination.

[0131] In step S601, receive M first data packets sent by the first terminal device, where the multiple first data packets are obtained by the first terminal device encapsulating the key data in the interaction data, and N of the M first data packets are encrypted by the first terminal device. M is a natural number greater than 1, N is greater than or equal to 1 and less than M.

[0132] The operations of the first terminal device for obtaining, encapsulating, encrypting, and sending the key data in this step have been introduced in detail in the embodiments of the first aspect, so they will not be repeated here.

[0133] In step S602, decrypt the N encrypted first data packets to obtain encrypted information.

[0134] First, the first data packets with encryption identifiers among the M first data packets can be determined as the first data packets that have undergone encryption processing. Next, decrypt the first data packets that have undergone encryption processing. After decryption, not only the decrypted first data packets are obtained, but also the encryption information added by the first terminal device during the decryption process is obtained.

[0135] After decrypting the N first data packets that have undergone encryption processing, the M first data packets can be parsed in sequence according to the reception order to obtain the key data, and the key data can be presented according to the presentation method of the key data. Exemplarily, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

[0136] In step S603, the encryption information is sent to the first terminal device so that the first terminal device continues to send the interaction data.

[0137] The operations of the first terminal device in receiving, verifying the encryption information and continuing or stopping sending the interaction data according to the verification result in this step have been introduced in detail in the embodiments of the first aspect, so they will not be repeated here.

[0138] In addition, the second terminal device can also receive a plurality of second data packets sent by the first terminal device, where the plurality of second data packets are obtained by the first terminal device encapsulating the non-key data in the interaction data; and the plurality of second data packets are parsed in sequence according to the reception order to obtain the non-key data; and the non-key data is presented according to the presentation method of the non-key data. Exemplarily, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

[0139] In addition, the second terminal device can also receive a plurality of third data packets sent by the first terminal device, where the plurality of third data packets are obtained by the first terminal device encapsulating the interaction data without key data; and the plurality of third data packets are parsed in sequence according to the reception order to obtain the interaction data; and the interaction data is presented according to the presentation method of the interaction data. Exemplarily, if the non-key data is a picture, the image can be displayed; if the non-key data is a video, the video can be played.

[0140] Reference can be made to the appendix Figure 7, which shows the processing flow of the second terminal device, Terminal B, after receiving the interaction data. After receiving the data, Terminal B first determines whether decryption is required; if decryption is not required, that is, the data is non-critical data in the interaction data with critical data or interaction data without critical data, then the data is parsed and displayed; if decryption is required, the data is encrypted, and the decrypted data is parsed and displayed. At the same time, the encryption information I is obtained during the decryption process, and then the encryption information I is sent to Terminal A, which is the first terminal device. Terminal A determines whether the information I is correct. If it is correct (i.e., passes the verification), the data is continued to be sent. If it is incorrect (i.e., fails the verification), the data sending is terminated.

[0141] Based on the display of the interaction data by the second terminal device, the user can operate on the display result of the interaction data, such as operating on the screen mirroring interface displayed by the second terminal device; the second terminal device can generate an interaction control instruction based on the operation of the user on the display result of the interaction data, and send the interaction control instruction to the first terminal device to enable the terminal device to continue to return the interaction data.

[0142] The data interaction methods introduced in the above two aspects can be combined to obtain the following data interaction method. In this data interaction method, the first terminal device continuously obtains interaction data according to the interaction control instruction (the interaction control instruction is generated based on the operation of the user on the first terminal device or the second terminal device), and sends the interaction data after encapsulation to the second terminal device. The second terminal device unpacks the received interaction data and then displays it, such as displaying a picture and playing audio and video, etc. There is critical data in the above interaction data, and the critical data involves user privacy or account information, so it needs to be encrypted for protection. Therefore, after encapsulating the critical data, a part of the obtained multiple first data packets is encrypted and then sent to the second terminal device. The second terminal device that receives the encrypted first data packet needs to decrypt it first, then unpack it, and then display it. At the same time, the encrypted first data packet in the critical data also serves as a security verification means in the data interaction process, that is, the encryption information is added during the encryption process of the first data packet, and the second terminal device will obtain the encryption information after decryption and return the encryption information to the first terminal device. Therefore, when the first terminal device receives the correct encryption information, it means that the current interaction process is safe and the data interaction can continue. When the first terminal device does not receive the correct encryption information, it means that the current interaction process is unsafe and the data interaction can be stopped.
