Detailed ways

The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

The present disclosure provides a data relay method, apparatus, system, storage medium, equipment and vehicle to implement data relay of applications.

FIG. 1 is a flow chart of a data relay method according to an exemplary embodiment. As shown in FIG. 1 , the method can be applied to a first device, and includes the following steps:

S101: Establish a data transmission channel with a second device.

The first device is one of the mobile device and the vehicle-mounted device, and the second device is the other of the mobile device and the vehicle-mounted device.

It is understandable that the data transmission channel between the first device and the second device can be used for a first application on the first device and a second application on the second device to perform data relay between each other, wherein the first application and the second application can be the same application deployed on different devices.

S102: Acquire an application data packet of a first application program in a first device based on a first relay SDK.

The first relay SDK is integrated into the first application, and the application data packet includes usage progress information of the first application on the first device.

It should be noted that in the process of developing applications, a software development kit (SDK) can be used to assist in development. Different SDKs can integrate different functions, such as communication functions and data acquisition functions.

The technical solution provided by the embodiments of the present disclosure can integrate a first relay SDK for a first application on a first device, and integrate a second relay SDK for a second application on a second device. The relay SDK integrated on the application can be used to define parameter information (i.e., usage progress information) that characterizes the usage progress of the application. For different applications, the parameter information that can be used to characterize their usage progress is different, and thus the parameter information defined by the relay SDK integrated by the application is also different.

For example, for a video playback application, the parameter information that characterizes the application's usage progress defined by the Relay SDK may include the video name, video definition, and video playback progress of the currently playing video. For a map application, the information that characterizes the application's usage progress defined by the Relay SDK may include the current location and the route being navigated. Thus, for different applications, different application data packages can be generated based on the Relay SDK integrated thereon.

In this embodiment, the application data packet of the first application program may be generated according to the parameter information defined by the first relay SDK on the first application program currently used by the first device.

In addition, it is worth noting that, since corresponding functions can be developed for the relay SDK according to actual conditions (for example, the relay SDK can be configured to define different parameter information or other information required for data relay according to actual conditions), and the relay SDK with corresponding functions is integrated into the application, the relay SDK on the application can have high operability. Therefore, based on the relay SDK integrated in the application, the usage progress information and other necessary information required for data relay can be flexibly obtained, thereby improving the accuracy of data relay.

S103, sending an application data packet to the second device, where the application data packet is used by a second relay SDK integrated in a second application in the second device to control the use progress of the second application to be consistent with the use progress of the first application on the first device.

It is not difficult to understand that the relay SDK integrated in the application can also be used to control the usage progress of the application. Therefore, the application data packet sent to the second device can be used by the second relay SDK integrated in the second application in the second device to control the usage progress of the second application to be consistent with the usage progress of the first application on the first device.

Referring to Fig. 2, Fig. 2 is a schematic diagram of interaction between a first device 201 and a second device 202 according to an exemplary embodiment. As shown in Fig. 2, the technical solution provided by the embodiment of the present disclosure can integrate corresponding device SDKs (first device SDK 2013 and second device SDK 2023 as shown in Fig. 2) for the first application 2011 on the first device 201 and the second application 2021 on the second device 202 on the basis of integrating the first relay SDK 2012 and the second relay SDK 2022.

Among them, corresponding functions can be integrated into the device SDK according to actual conditions, such as functions for establishing a data transmission channel, generating public and private keys, performing device identity authentication, and transmitting encrypted signature data packets. Based on these functions of the device SDK, a data transmission channel can be established, and application data packets can be encrypted and authenticated based on the generated public and private keys, thereby relaying data based on the SDK on the device without relying on logging in to the same account on different devices for authentication.

It is not difficult to understand that data relay based on relay SDK and device SDK can further improve the convenience of data relay on the basis of improving the accuracy of data relay.

Optionally, before the above step S102, the technical solution provided by the embodiment of the present disclosure may include:

In response to detecting that the application program running in the foreground of the first device is integrated with the first relay SDK, the application program integrated with the first relay SDK is used as the first application program.

It is understandable that the application running in the foreground of the first device may refer to the application currently used by the first device. In the case where the application running in the foreground of the first device is integrated with the first relay SDK, the application may be used as the first application that can perform data relay. Thus, the application data packet of the first application may be obtained based on the first relay SDK on the first application of the first device, and data relay may be performed with the second application of the second device based on the established data transmission channel.

Optionally, the above step S101 may include:

When feedback information sent by the second device is received, a data transmission channel is established with the second device, wherein the feedback information is sent by the second device to the first device when the identity of the first device is successfully authenticated according to the first public key;

The first public key is generated at least according to the identification code of the first device, the feedback information includes the second public key, and the second public key is generated at least according to the identification code of the second device.

It should be noted that if the first device receives the feedback information sent by the second device, it can indicate that the second device has passed the identity authentication of the first device, so the application data packet can be transmitted. In this process, the first device and the second device perform reliable identity authentication based on the public key, thereby ensuring that the application data packet can only be parsed on the device authenticated by the public key on the basis of realizing data relay, thereby further improving the security of data relay.

In a possible implementation, the second device can obtain the device information stored in the database through the interface provided by the second device SDK on the second device, and obtain the identification code of the first device corresponding to the first public key output by the public key conversion program preset in the second device SDK by inputting the first public key into the second device SDK. On this basis, it can be determined whether the identity authentication of the first device is successful by determining whether there is a target identification code consistent with the identification code of the first device in the device information.

It should also be noted that the first public key corresponds to the first private key, and the second public key corresponds to the second private key. The first public key and the first private key can be a function program for generating public and private keys in the first device based on the preset function program in the SDK of the first device. The second public key and the second private key can be generated in the second device based on the function program for generating public and private keys preset in the second device SDK. Since the same function program provided by the device SDK is used to generate the public key and the private key, the corresponding relationship between the public key and the private key can be guaranteed.

Specifically, the first private key may be generated based on the identification code of the first device and the identification information of the first application, and the first public key may be a public key corresponding to the first private key generated based on the identification code of the first device and the identification information of the first application. Similarly, the second private key may be generated based on the identification code of the second device and the identification information of the second application, and the second public key may be a public key corresponding to the second private key generated based on the identification code of the second device and the identification information of the second application.

Among them, the identification code of the device can be used to uniquely identify the device, for example, it can be the International Mobile Equipment Identity (IMEI), or it can be other identification codes that can uniquely identify the device. The identification information of the application can refer to the package name of the application package, and the package names of different application packages are different. For example, for application A, its package name can be com.auto.yingyongA. The identification code of the device and the identification information of the application can be determined according to the actual situation, and this disclosure does not make specific limitations on this.

In a possible implementation, after the first device receives the feedback information sent by the second device, it can authenticate the second device according to the second public key included in the feedback information, and establish a data transmission channel with the second device if the second device is authenticated. In this process, the first device and the second device authenticate their respective devices through the public keys sent to each other, thereby establishing a secure and reliable data transmission channel.

In addition, the first device SDK on the first device may preset a functional program for communication, and the feedback information sent by the second device may include a communication interface provided by the second device SDK on the second device, so that the first device may send an application data packet to the communication interface provided by the second device SDK through the first device SDK thereon. In this way, other devices may not be able to identify the communication between the first device and the second device.

Optionally, the above step S103 may include:

Encrypting an application data packet of the first application based on the second public key, and signing the encrypted application data packet based on a first private key corresponding to the first public key of the first device to obtain an encrypted signature data packet;

The encrypted signature data packet is sent to the second device, where the encrypted signature data packet is used by the second device to perform signature authentication based on the first public key, and the encrypted signature data packet is decrypted based on the second private key corresponding to the second public key of the second device to obtain an application data packet of the first application.

Among them, for the application data packet of the first application, after the application data packet is encrypted by the second public key and the encrypted application data packet is signed by the first private key, the encrypted signature data packet thus obtained is only The analysis can be performed in the second device storing the first public key and the second private key. That is to say, the application data packet is encrypted and signed using the second public key and the first private key to obtain an encrypted signature data packet, so that the second device can authenticate the encrypted signature data packet according to the first public key and the second private key. In this way, data relay can be performed according to the SDK on the device without relying on logging in to the same account on different devices for authentication, thereby improving the security and convenience of data relay.

For example, the second device may use the first public key to sign and authenticate the encrypted signature data packet to obtain an encrypted data packet that passes the signature authentication, and then use the second private key to decrypt the encrypted data packet to obtain the application data packet of the first application.

In addition, it should be noted that there can be multiple first applications and multiple second applications, and the multiple first applications and multiple second applications correspond one to one. The first public key of each first application is stored in the second relay SDK of the corresponding second application, and the second public key of each second application is stored in the first relay SDK of the corresponding first application, so that the encrypted signature data packet of any first application can be decrypted and signed and authenticated by the second application corresponding to the first application.

Since the public key and the private key correspond one to one, when each application data packet uses different public and private keys, the generated encrypted signature data packets do not affect each other, and the relay of multiple applications between the first device and the second device can be realized at the same time.

In a possible implementation, each first application can generate an application data packet based on the first relay SDK integrated thereon, and use corresponding public and private keys (such as the first private key and the second public key) to encrypt and sign the application data packet, so that the generated encrypted signature data packet corresponds to the first application one by one. The encrypted signature data packets corresponding to different first applications do not affect each other.

Optionally, the data transmission channel established by the first device and the second device may be a data transmission channel based on near field communication.

It should be noted that near field communication may include Bluetooth communication and WiFi direct communication, etc. In one possible implementation, the first device may send a near field communication connection request via Bluetooth broadcast, so that the second device authenticates the second device according to the first public key included in the near field communication connection request. Thus, when the first device authenticates the second device, Bluetooth may be used to transmit a data packet with a smaller data volume, or WiFi (Wireless Fidelity) may be used to directly transmit a data packet with a larger data volume. The size of the data volume may be determined based on a preset data volume (the preset data volume may be determined based on actual conditions, and the present disclosure does not specifically limit this). For example, a data packet with a data volume greater than or equal to the preset data volume is determined as a data packet with a larger data volume, and accordingly, A data packet whose data volume is smaller than a preset data volume is determined as a data packet with a smaller data volume.

It is not difficult to understand that there is almost no risk of network intrusion when transmitting data in a data transmission channel based on near field communication. Therefore, on the basis of using the first relay SDK, the second relay SDK, the first device SDK and the second device SDK to realize data relay between the first device and the second device, further using near field communication to establish a data transmission channel between the two can improve the security of data transmission, thereby further improving the security of data relay.

Optionally, the above step S102 may include:

Following the increase in the usage progress of the first application on the first device, obtaining in real time an application data packet of the first application on the first device based on the first relay SDK;

Based on this, the above step S103 may include:

As the usage progress of the first application on the first device increases, the application data packet of the first application in the first device is sent to the second device in real time, so that the usage progress of the second application is consistent with that of the first application in real time. The application data flow between different brands and types of mobile phones and car machines is established to improve the user experience.

For example, the application data packet of the first application on the first device can be sent to the second device in real time through multi-screen collaboration, so that the usage progress of the second application on the second device is consistent with the first application in real time. Optionally, the technical solution provided by the embodiment of the present disclosure may also include:

receiving an application data packet of a second application sent by a second device, where the application data packet of the second application includes usage progress information of the second application;

It is not difficult to understand that the usage time represented by the usage progress information of the second application is later than the usage time represented by the current usage progress of the first application, which can indicate that the usage progress information of the second application is the latest. Therefore, based on the first relay SDK integrated in the application, the usage progress of the first application can be controlled to be consistent with the usage progress of the second application on the second device.

In a possible implementation, the first device may be a vehicle-mounted device, and the second device may be a mobile device. Therefore, before the above step S102, the following may also be included:

Make sure the vehicle is in the preset gear.

The preset gear position can be determined according to actual conditions, for example, it can be the P gear position representing parking. This is not specifically limited.

For example, after the vehicle is parked (that is, the vehicle gear is in the P gear), the user usually uses the mobile device to continue using the application used on the vehicle-mounted device. Therefore, the vehicle-mounted device can obtain the application data packet of the first application based on the first relay SDK on the vehicle-mounted device, and send the application data packet to the mobile device, so that the mobile device controls the use progress of the second application based on the second relay SDK to be consistent with the use progress of the first application on the vehicle-mounted device. In this way, a seamless flow from the first application on the vehicle-mounted device to the second application on the mobile device can be achieved.

In one possible implementation, after receiving the application data packet of the second application on the vehicle-mounted device, the first application corresponding to the second application can be pushed to the user on the mobile device so that the user opens the first application on the mobile device, thereby completing the data relay of the application.
