Description

Technical Field

[0001] The present invention relates to the technical field of Bluetooth dual connection of mobile phone APP, and in particular to an instrument interaction method for safely acquiring sensitive information of a mobile phone. Background Art

[0002] As vehicle instruments (especially motorcycle instruments) have become more color-screen and intelligent in recent years, more and more vehicle instruments have the function of interacting with mobile phones. The instruments can display incoming calls, application messages, navigation screen projection and other information. At the same time, APP can also obtain real-time operating data, diagnostic records and other content from the instruments.

[0003] At present, taking motorcycle instruments as an example, if you want to display incoming calls and all application message contents of Android phone users, the APP installed on the phone needs to obtain the permission to use the notification center, so as to obtain the user's sensitive data, and then send it to the instrument via Bluetooth (conventional instruments do not have networking functions). However, the vehicle-mounted instrument also has functions such as navigation display, which requires the APP to have functions such as navigation screen projection in addition to notification usage rights, and functions such as navigation screen projection require the APP to be connected to the Internet (map information acquisition, etc.). At the same time, the APP generally has functions such as instrument firmware upgrades or user registration, so the networking function is indispensable. At present, after the APP applies for notification usage rights and network usage rights at the same time, users will worry that application messages, incoming calls and other content will be transmitted to the network by the APP, resulting in the leakage of user sensitive data. Most users will refuse some sensitive permissions applied for by the APP, resulting in some functions being unavailable. For this reason, we propose an instrument interaction method for securely obtaining sensitive information from mobile phones. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an instrument interaction method for safely obtaining sensitive information of a mobile phone.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An instrument interaction method for securely obtaining sensitive information of a mobile phone comprises the following steps:

[0007] Step 1: Instrument preparation;

[0008] Step 2: Split the mobile phone APP into two completely independent APPs. The two completely independent APPs are the message notification center APP and the navigation application APP, and they can run on the same mobile phone;

[0009] Step 3: The instrument Bluetooth transmits a broadcast signal. If the mobile phone's message notification center APP requests to connect with the instrument Bluetooth, the instrument Bluetooth first performs Bluetooth pairing and establishes a connection;

[0010] Step 4. After the Bluetooth of the instrument is connected to the Message Notification Center APP of the mobile phone, the Bluetooth of the instrument will automatically memorize the Bluetooth MAC address of the connected mobile phone, and then the Bluetooth of the instrument will continue to transmit new broadcast signals. If the navigation application APP initiates a connection request, and the MAC address of the mobile phone in the new connection request is different from the memorized MAC address, the Bluetooth of the instrument will refuse the connection and resend the new broadcast signal. Otherwise, the Bluetooth of the instrument will receive the connection.

[0011] Step 5. After the navigation application APP in step 4 establishes a connection with the instrument Bluetooth, the navigation application APP updates data according to the new broadcast signal initiated by Bluetooth, and then sends the message to the instrument by using the regular data channel, so that the instrument Bluetooth establishes a second connection with the same mobile phone.

[0012] As a further preferred embodiment of the present technical solution: in step three, the Bluetooth module in the instrument Bluetooth adopts BLE5.0 or above, which can support multiple data channels.

[0013] As a further optimization of the present technical solution: in the step 2, the message notification center APP and the navigation application APP are completely independent and have no connection with each other. After the message notification center APP receives the message from the mobile phone or application, it uses the message dedicated channel to send the message to the instrument, and then the instrument updates the display. The message notification center APP has the right to use notifications and Bluetooth, and the navigation application APP has the right to use the network and storage.

[0014] As a further optimization of the technical solution: in the step four, the APP for the message notification center APP and the navigation application APP respectively communicate with the instrument Bluetooth using different data channels for connection communication, and the data channels are designed as follows: the UUID of the message notification center channel is FEE4, and the UUID of the navigation application channel is FEE1 and FEE2, FEE1 is responsible for information notification, and FEE2 is responsible for information writing.

[0015] As a further preferred embodiment of the present technical solution: data from different data channels all adopt the same data format but have different command words. The instrument uses a single data parsing process to sequentially parse each instruction, and can determine the source of the current data by judging the command word and parse and display it.

[0016] As a further optimization of the present technical solution: in step five, the instrument Bluetooth also supports Apple's ANCS protocol, realizing the notification center role of IOS. When connected to an Apple mobile phone, there is no need for a message notification center APP. The mobile phone's operating system will directly push incoming calls, application messages and other content to the instrument Bluetooth. Therefore, on Apple devices, only a navigation application APP is needed.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention separates the message notification center APP and the navigation application APP with notification usage rights into two completely independent APPs, which can run on the same mobile phone, so that the instrument's Bluetooth supports dual connections with the same mobile phone, thereby making the sensitive data permission APP on the mobile phone completely isolated and independent from the networked APP, and users do not need to worry about the leakage of sensitive or privacy data.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-2 , an instrument interaction method for securely obtaining sensitive information of a mobile phone, comprising the following steps:

[0023] Step 1: Instrument preparation;

[0024] Step 2: Split the mobile phone APP into two completely independent APPs. The two completely independent APPs are the message notification center APP and the navigation application APP, and can run on the same mobile phone. The message notification center APP and the navigation application APP are completely independent and have no connection with each other. After the message notification center APP receives the mobile phone or application message, it uses the message dedicated channel to send the message to the instrument, and then the instrument updates the display. The message notification center APP has the right to use notifications and Bluetooth, and the navigation application APP has the right to use the network and storage.

[0025] Step 3: The Bluetooth module in the instrument Bluetooth uses BLE5.0 or above, which can support multiple data channels. The instrument Bluetooth transmits broadcast signals. If the message notification center APP of the mobile phone requests to connect with the instrument Bluetooth, the instrument Bluetooth first performs Bluetooth pairing and establishes a connection;

[0026] Step 4. After the instrument Bluetooth establishes a connection with the mobile phone's message notification center APP, the instrument Bluetooth will automatically memorize the Bluetooth MAC address of the connected mobile phone, and then the instrument Bluetooth will continue to transmit new broadcast signals. If the navigation application APP initiates a connection request, and the MAC address of the mobile phone in the new connection request is different from the memorized MAC address, the instrument Bluetooth will refuse the connection and resend the new broadcast signal. Otherwise, the instrument Bluetooth will receive the connection. The APPs for the message notification center APP and the navigation application APP use different data channels for communication with the instrument Bluetooth. The data channels are designed as follows: the UUID of the message notification center channel is FEE4, and the UUID of the navigation application channel is FEE1 and FEE2. FEE1 is responsible for information notification, and FEE2 is responsible for information writing. Data from different data channels use the same data format, but have different command words. The instrument uses a single data parsing process to parse each instruction in sequence, and can determine the source of the current data by judging the command word and parse and display it.

[0027] Step 5. After the navigation application APP in step 4 establishes a connection with the instrument Bluetooth, the navigation application APP updates the data according to the new broadcast signal initiated by Bluetooth, and then sends the message to the instrument by using the regular data channel, so that the instrument Bluetooth establishes a second connection with the same mobile phone. The instrument Bluetooth also supports Apple's ANCS protocol and realizes the notification center role of IOS. When connected to an Apple phone, there is no need for a message notification center APP. The mobile phone's operating system will directly push incoming calls, application messages and other content to the instrument Bluetooth. Therefore, on Apple devices, only one navigation application APP is needed.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
