Detailed Description
Hereinafter, example embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein.
As described above, the conventional bluetooth sharing scheme has the following problems:
1. the token needs to be exposed in the Bluetooth sharing process, and if the token is leaked by the sharing request equipment without authorization of the Bluetooth equipment to be shared or a controller of the sharing request equipment, the Bluetooth equipment to be shared faces a security risk;
2. the sharing request device directly establishes a communication channel with the sharing device by using the token, and a controller of the Bluetooth device to be shared cannot participate in and monitor the Bluetooth sharing process;
3. the bluetooth sharing process usually depends on a wireless network and a background server (cloud), and once any party cannot connect with the cloud, the sharing process cannot be performed.
Aiming at the defects in the prior art, the basic idea of the application is that the control device of the Bluetooth device to be shared distributes the permission code to the sharing request device, participates and monitors the Bluetooth sharing process, avoids exposing the token to the sharing request device, and enhances the Bluetooth sharing safety. Moreover, the Bluetooth sharing process does not need cloud participation and can be completed locally through Bluetooth communication. Accordingly, the present application provides a method of requesting sharing of a bluetooth device, a method executed by a control device to control sharing of a bluetooth device to be shared, an electronic device, a computer program product, and a computer-readable storage medium, which can control and manage bluetooth connection between the bluetooth device to be shared and a sharing request device by assigning a permission code to the sharing request device through the control device of the bluetooth device to be shared, without using a token for distributing the bluetooth device to be shared to the sharing request device, and without cloud participation in a bluetooth sharing process.
It should be noted that the basic concept of the present application can be applied to smart home or smart wearable scenes, and can also be applied to other system applications as long as the related devices participating in communication have a bluetooth communication function. For example, the present application is equally applicable to bluetooth device sharing applications in an industrial environment.
Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Fig. 1 illustrates a system topology for bluetooth device sharing according to an exemplary embodiment of the present application, which shows a typical bluetooth sharing application scenario. As shown in fig. 1, the sharing request device B requests the device E to be shared to perform bluetooth sharing, and the control device a controls a bluetooth sharing process of the device E to be shared. Taking a home environment as an example, a mobile phone or a tablet device of a host may serve as the control device a, which controls smart home devices serving as the devices to be shared E, such as a sound box, a television, and the like. The guest's mobile phone or tablet device may serve as a sharing request device B that requests sharing to use an intelligent home device such as a speaker, a television, etc. The control device a, the sharing request device B, and the device to be shared E each have a bluetooth communication module so that various bluetooth operations described in detail below can be performed. Further, the control device a and the sharing request device B may also have a second communication module different from the bluetooth communication module, for example, a WIFI communication module, an internet communication module, or a mobile communication module such as 3G, 4G, and 5G, so that the control device a and the sharing request device B may also communicate with each other by other communication means other than bluetooth. The cloud represents a background server, and generally provides necessary auxiliary background services through various wireless communication modes, which will be described in detail later.
It should be noted that the above application scenarios are only shown for the convenience of understanding the spirit and principles of the present application, and the embodiments of the present application are not limited thereto. Rather, embodiments of the present application may be applied to any scenario where it may be applicable. For example, in any application environment such as home, industry, and the like, two or more sharing request devices may be included, the device to be shared and the control device may also be one or more pairs, and one control device may also control two or more devices to be shared.
In the following, with reference to fig. 2, a bluetooth device sharing method according to an exemplary embodiment of the present application is described with reference to an application scenario of fig. 1.
Fig. 2 illustrates a flowchart of a bluetooth device sharing method according to an exemplary embodiment of the present application.
As shown in fig. 2, the bluetooth device sharing method 100 includes a method of requesting sharing of a bluetooth device and a method executed by a control device to control sharing of a bluetooth device to be shared.
In step S110, the sharing request device B may listen to the bluetooth broadcast. When the bluetooth connection is not established, the device to be shared E may continuously send a bluetooth broadcast, and the bluetooth broadcast may carry device information of the device to be shared E, such as a device type ID, a device unique identifier dID, a device MAC address, and the like. However, the formats of the bluetooth broadcasts of different devices may be different from each other. For example, a bluetooth broadcast of a device produced by a particular manufacturer may have its particular format. Therefore, the sharing request device B may need to identify the format of the bluetooth broadcast when it listens to the bluetooth broadcast.
In step S112, the sharing request device B determines whether the format of the bluetooth broadcast is recognizable. The sharing requesting device B may match the format of the monitored bluetooth broadcast with a known bluetooth broadcast format, for example, perform a matching process by regular pattern matching to determine whether the monitored bluetooth broadcast format is recognizable, i.e., is a known format. Here, the sharing request device B may locally store a plurality of known bluetooth broadcast formats, for example, a specific bluetooth format of a common manufacturer.
If the sharing request device B fails to recognize the format of the monitored bluetooth broadcast in step S112, the sharing request device B may request the cloud to recognize the bluetooth broadcast format. For example, in step S114, the sharing requesting device B may upload the description information of the device E to be shared to the cloud. The description information of the device to be shared E may be, for example, a photo image of the device to be shared, or a description language about the device type, brand, model, and the like of the device to be shared, or a sample of bluetooth broadcast of the device to be shared E, and the like. In step S116, the cloud program identifies the device E to be shared according to the description information, and issues the bluetooth broadcast format to the sharing requesting device B. After receiving the bluetooth broadcast format issued by the cloud, the sharing request device B may store the format locally as a known bluetooth broadcast format.
If the sharing request device B successfully identifies the bluetooth broadcast format in step S112 or receives the bluetooth broadcast format from the cloud in step S116, the sharing request device B parses the monitored bluetooth broadcast according to the bluetooth broadcast format in step S120, so as to obtain device information of the device E to be shared, including, for example, a device type ID, a device unique identifier dID, a device MAC address, and the like.
Next, in step S130, the sharing request device B sends a bluetooth sharing request to the device to be shared E through bluetooth broadcast. For example, the sharing request device B may send a bluetooth broadcast for 5 seconds, and then switch to scanning the bluetooth broadcast for 5 seconds to receive a response to the sharing request; this continues until the requesting device B exits the page or times out. The bluetooth broadcast sent by the sharing request device B may conform to the bluetooth broadcast format of the device to be shared E, and may include a request sharing instruction, device information of the device to be shared E, and request device information. The request device information may be device information of the sharing request device B, such as a device type ID, a device unique identifier dID, or a device MAC address, or may also be information of a user of the sharing request device B, such as a userid (identifier) of the user, where the userid is a unique identifier of each user, and may be, for example, a cloud-assigned 10-bit numeric string.
In an example, the information of the bluetooth device to be shared may include only the MAC address of the bluetooth device to be shared E, and the information of the sharing request device may include only the MAC address of the sharing request device B. In another example, the information of the bluetooth device to be shared may further include one or more of a type ID, a device unique identifier dID, and a user ID (userid) of the bluetooth device to be shared, and the information of the sharing request device further includes one or more of a type ID, a device unique identifier dID, and a user ID of the sharing request device B. For example, when the userid of the device to be shared E is different from the userid of the sharing request device B, the device to be shared E and the sharing request device B cannot directly establish a bluetooth connection.
In step S142, the control device a also listens to the bluetooth broadcast, and parses the listened bluetooth broadcast, and determines that the listened bluetooth broadcast includes a sharing request. Then, in step S144, the control device a determines whether the device to be shared is a device controlled by itself according to the information of the device to be shared E included in the sharing request in the bluetooth broadcast. For example, control device a may maintain locally a list of bluetooth devices it controls, including information of the bluetooth devices controlled, such as device MAC addresses, etc. The control device a may compare the MAC address of the bluetooth device to be shared requested in the sharing request bluetooth broadcast with the MAC addresses in the local list. If no match is found, the control device a determines that the bluetooth device to be shared requested in the bluetooth broadcast is not the device it controls, the control device a ignores the bluetooth broadcast, and the flow of the method 100 returns to step S142 to continue listening to the bluetooth broadcast. If a match is found, the control device a determines that the bluetooth device to be shared requested in the bluetooth broadcast is the device it controls, and the flow of the method 100 continues to step S146.
In step S146, the control device a responds to the bluetooth sharing request from the sharing requesting device B. That is, the user of the control device a determines whether to allow the sharing requesting device B to establish a bluetooth connection with the device to be shared E. The user of the control device a may respond according to the information of the sharing request device B. In one embodiment, the user of the control device a may also view specific personal information of the user, such as head portrait, nickname, name, gender, age, etc., in the cloud according to the information of the user of the sharing request device B, such as the userid of the user. In such an embodiment, the control device a, the sharing request device B, and the cloud may run related app programs, and users of the control device a and the sharing request device B are registered as users on the app.
For example, when the user of the control device a finds that the sharing request device B or the user thereof is an unfamiliar device or an unfamiliar user, the sharing request may be selected to be ignored. At this time, the control device a does not respond to the sharing request, and the flow of the method 100 returns to step S142, and the control device a continues to monitor the bluetooth broadcast. If the request device B does not receive any response within the preset time, the request device B is timed out and quits. If the user of the control device a finds that the sharing request is a malicious request, it may also choose to reject the request. At this time, the control device a adds the sharing request device B to the blacklist, and the control device a automatically ignores the sharing request from the sharing request device B. Alternatively, the control device a may send a rejection message to the sharing request device B in step S148, and then the flow of the method 100 returns to step S142, and the control device a continues to listen to the bluetooth broadcast. If the user of the control device a finds that the sharing request is from a known source, such as a close friend, he can select to pass the sharing request and send a message to the sharing request device B that the sharing request passed. If the control device a decides to accept the sharing request of the sharing request device B, the control device a may record the MAC address of the sharing request device B. Here, the message that the control device a sends to the sharing request device B to pass or reject the sharing request may be sent in a bluetooth broadcast form, or may be sent through WIFI, the internet, or a mobile communication network via a cloud. Upon passing the request, the message passing the request may also include information related to control device a, such as its device MAC address or user information.
When the sharing request device B receives a message passing the sharing request from the control device a, the sharing request device B stops sending the request sharing broadcast, and an icon of the device E to be shared may appear in the device list available to the sharing request device B. The sharing request device B may record the MAC address of the control device a.
In one embodiment, as shown in step S160, the user of the sharing request device B may click the icon, and the sharing request device B may establish a communication connection with the control device a, and send a permission code request to the control device a through the communication connection.
In another embodiment, as shown in step S152, before step S160, the sharing requesting device B may initiate a bluetooth connection request to the device E to be shared. Then, in step S154, the device E to be shared returns a bluetooth broadcast message to the sharing requesting device B, requesting a permission code. In response to the message requiring the license code, the flow of the method 100 proceeds to step S160.
In step S172, the control device a may return a permission code for performing bluetooth connection with the device E to be shared to the sharing request device B through the communication connection established by the sharing request device B. If the sharing requesting device B does not receive the returned permission code (no in step S172), the process of the method 100 proceeds to step S176, the device E to be shared is unavailable, and the process of the method 100 ends. If the sharing request device B receives the returned permission code (yes in step S172), in step S180, the sharing request device B may perform a bluetooth connection with the device to be shared E. At this time, the sharing request device B may send the license code to the device to be shared E, and the device to be shared E checks the validity of the license code, and if invalid, disconnects the connection.
The license code may be a 16-bit string, which includes a device MAC address, a timestamp, an effective duration, a usage right, and the like, and may be encrypted by a token. The token is a secret key for communication between the control device and the device to be shared, and the device to be shared can obtain the information through decryption after receiving the token. The permission code is time-efficient, determined by the length of time of validity. In addition, the license code generation mode is various, and the license code can be placed at the cloud end or the local mobile end. One license code can be generated at a time, and a plurality of license codes can be generated in batch at a time, so that the mode is very flexible. The expression form of the license code may also be not limited to a character string, but may also be a barcode, a two-dimensional code, or another form, as long as the sharing requesting device B can recognize and convert the sharing requesting device B into an encrypted string that can be recognized by the device E to be shared.
The communication connection established between the sharing request device B and the control device a is not necessarily limited to bluetooth, and may adopt any communication mode, including bluetooth WIFI, internet or mobile communication network, or may communicate via a cloud.
The device E to be shared may set a timer to calculate the time elapsed after the sharing request device B establishes a bluetooth connection with the device E to be shared. According to the effective duration of the permission code received from the sharing request device B, the device E to be shared may push a notification by bluetooth to notify the sharing request device B that the permission code needs to be updated even if the time is out. At this time, the sharing request device B may request the update permission code through the communication connection established with the control device a. The user of the control device a decides whether to update the license code according to its predetermined rule. If the license code is approved to be updated, relevant information in the license code, such as a timestamp, an effective time length and the like, is updated, and then the sharing request device B is returned. The sharing request device B can send the updated permission code to the device E to be shared, the device E to be shared checks the validity of the permission code, and the Bluetooth connection with the sharing request device B is continued according to the updated permission code. If the device E to be shared does not receive the updated permission code after the validity duration (expiration) is exceeded, the device E to be shared can disconnect the bluetooth connection by itself.
In an example, the control device a may interrupt communication between the control device B and the device at any time, and by setting the valid duration of the permission code to be short, it is convenient to control the time for the third party user of the sharing request device B to use the device to be shared more finely.
Therefore, by adopting the method for requesting sharing of the bluetooth device or the method executed by the control device to control sharing of the bluetooth device to be shared according to the embodiment of the present application, the control device of the bluetooth device to be shared can allocate the permission code to the sharing request device to control and manage bluetooth connection between the bluetooth device to be shared and the sharing request device, without distributing the token of the bluetooth device to be shared to the sharing request device, and the bluetooth sharing process does not need cloud participation (the cloud merely participates in identification of a new bluetooth broadcast format). According to the Bluetooth sharing scheme, tokens do not need to be exposed, so that the Bluetooth sharing safety is enhanced; the permission code distributed to the sharing request device is temporary and becomes invalid after the effective duration is exceeded, and the Bluetooth sharing duration can be controlled by setting the effective duration of the permission code; although the sharing request device directly establishes the bluetooth communication with the bluetooth device to be shared, the communication process is strictly controlled by the control device, and therefore the bluetooth communication is controllable. In addition, the Bluetooth sharing process is localized, cloud participation is not needed, and application is more convenient. Through the Bluetooth sharing, the control device can not directly participate in the communication between the sharing request device and the Bluetooth device to be shared, but controls the time efficiency and the authority through the dynamic permission code, and is low in coupling and effective.
