Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, a flowchart of a processing method according to an embodiment of the present application is provided, where the method may be applied to a first electronic device capable of performing data processing and data transmission, such as a mobile phone, a notebook, or a pad. The technical scheme in the embodiment is mainly used for improving the safety of data transmission of the electronic equipment.
Specifically, the method in this embodiment may include the following steps:
step 101: in case the identification information is a first value, it is detected whether the update condition is fulfilled, and if the update condition is fulfilled, step 102 is performed.
The identification information is information characterizing the first electronic device, such as an identification code uniquely characterizing the first electronic device, such as a universal unique identification code UUID (Universally Unique Identifier), etc. The identification information can be obtained by the second electronic device via the first communication connection, and after the identification information of the first electronic device is obtained by the second electronic device, the second electronic device can establish a second communication connection with the first electronic device, whereby the second electronic device and the first electronic device can perform data transmission via the second communication connection.
Note that, the first electronic device in this embodiment is a second electronic device in this application, and the first and second electronic devices in this application are for distinguishing two side electronic devices that perform data communication, and are not limited to a certain device.
Specifically, the case where the identification information is the first value generally refers to the case where the identification information is updated to the current value, and the case where the identification information is a specific value is not limited.
In this embodiment, when the identification information is updated to the first value, it is continuously detected whether the update condition is satisfied, that is, when the identification information is updated to the first value, it is detected whether the update condition corresponding to the identification information is satisfied in real time, if the update condition is not satisfied, it is continuously detected whether the update condition is satisfied, and if the update condition is satisfied, it is possible to execute step 102.
The update condition in this embodiment is for the identification information, and not only for the identification information of the first value. In a specific implementation, the update condition may be a condition regarding a duration in which the identification information is updated, or may be a condition regarding the number of times the identification information is acquired by other electronic devices. Based on this, in this embodiment, whether the update condition is satisfied may be determined by monitoring a parameter, such as a time length or a number of times, corresponding to the update condition.
In one implementation, the update condition may include: the number of times the identification information is obtained after the last time the identification information was updated is greater than or equal to the number of times threshold. That is, the first electronic device starts recording the number of times the identification information is obtained by other devices such as the second electronic device after the identification information is updated until the number of times the identification information is obtained is greater than or equal to the number-of-times threshold. For example, after the identification information is updated to the first value, the first electronic device records the number of times the identification information is acquired by the second electronic device through the first communication connection, and determines that the update condition is satisfied when the number of times is greater than or equal to a number of times threshold, such as greater than 5 times.
Specifically, the first electronic device may record the number of times the identification information is obtained by other devices, such as the second electronic device, by configuring a counter.
In another implementation, the update condition may include: the time period from the last interval at which the identification information was updated is greater than or equal to the time period threshold. That is, after the identification information is updated, the first electronic device starts timing until the recorded time length reaches the time length threshold. For example, after the identification information is updated to the first value, the first electronic device starts timing, and determines that the update condition is satisfied when the recorded time period exceeds 1 hour.
Specifically, the first electronic device may implement timing by configuring a timer.
In another implementation, the update condition may include: the number of times the identification information is obtained after the last identification information is updated is greater than or equal to a number of times threshold, and the time period from the interval when the last identification information is updated is greater than or equal to a time period threshold. That is, after the identification information is updated, the first electronic device starts recording the number of times the identification information is obtained by other devices such as the second electronic device while starting timing until the number of times the identification information is obtained is greater than or equal to the number of times threshold or the recorded time length reaches the time length threshold. For example, after the identification information is updated to the first value, the first electronic device starts timing while recording the number of times the identification information is acquired by the second electronic device through the first communication connection, and when the number of times is greater than or equal to a number threshold such as greater than 5 times or the recorded time period exceeds 1 hour, it may be determined that the update condition is satisfied.
Step 102: and updating the identification information to the obtained second value.
The second value may be generated in real time by the first electronic device, for example, when the update condition is satisfied, the first electronic device generates the second value, and then sets the second value as the current value of the identification information;
alternatively, the second value may be read by the first electronic device in a pre-generated and stored set of values, e.g. when the update condition is met, the first electronic device reads the second value in its stored set of values, and then sets the second value as the current value of the identification information.
The value set may include a plurality of values that are generated in advance, and the values may be arranged in a specific order, and when the first electronic device reads the values, one of the values may be read as the second value in a specific rule or order. For example, the first electronic device reads the second value randomly in the value set, or the second electronic device reads the value which has not been read or has been read less times in the order of the values, or the like.
Based on this, the second electronic device is able to establish a second communication connection with the first electronic device after the updated identification information is obtained by the second electronic device through the first communication connection.
If the second electronic device and the first electronic device perform data transmission through the second communication connection when the identification information is updated, at this time, the first electronic device notifies the second electronic device of the updated status of the identification information after updating the identification information, and the second electronic device re-acquires the updated identification information from the first electronic device through the first communication connection and re-establishes the second communication connection to continue data transmission. It can be seen that even if the identification information is acquired reversely, the communication connection cannot be established due to the change of the identification information after the identification information is updated, and thus data transmission cannot be performed.
Taking a first electronic device as a notebook computer and taking a second electronic device as a mobile phone as an example, detecting whether an update condition corresponding to a UUID (user identifier) is met on the notebook computer in real time, such as whether the number of times the UUID is read by other devices exceeds a limit or whether the update duration of the UUID is overtime, and the like, when the update condition corresponding to the UUID is met, updating the UUID once by the notebook computer, based on the update condition, firstly establishing a first communication connection between the mobile phone and the computer, such as NFC (near field communication) based on the first communication connection, obtaining the latest UUID of the computer by the mobile phone through the first communication connection, then establishing a second communication connection, such as Bluetooth connection, with the computer by the mobile phone, and transmitting data packets, such as videos or documents, between the mobile phone and the computer after the establishment of the second communication connection is completed.
As can be seen from the above technical solution, in the processing method according to the first embodiment of the present application, whether the update condition corresponding to the identification information representing the electronic device is satisfied is detected, so that when the update condition is satisfied, the identification information is updated from the first value to the obtained second value, and based on this, the identification information, after being obtained by other electronic devices through the first communication connection, can establish the second communication connection with the electronic device. Therefore, compared with the technical scheme that the fixation of the identification information of the electronic equipment can cause potential safety hazards in data transmission, in the embodiment, the value of the identification information is continuously updated by detecting whether the updating condition corresponding to the identification information is met or not in real time, so that even if the identification information is reversely acquired, the identification information reversely acquired is invalid because the identification information is updated, and effective communication connection is not established because the identification information is reversely acquired, thereby avoiding the potential safety hazards in data transmission and improving the safety of data transmission.
In one implementation, the first communication connection is established if a connection condition is satisfied between the first electronic device and the second electronic device.
Specifically, the connection conditions may be: the second electronic device is present in a communication range corresponding to the first communication connection of the first electronic device, or the distance between the second electronic device and the first electronic device is smaller than or equal to a communication distance threshold, where the communication distance threshold is related to the communication range of the first communication connection, based on which the first communication connection can be established between the second electronic device and the first electronic device.
Based on this, in the first communication connection, the first electronic device transmits at least the identification information, thereby enabling the second electronic device to establish at least a second communication connection according to the identification information after the identification information is obtained, and the established second communication connection enables data transmission between the first electronic device and the second electronic device.
The data transmitted in the second communication connection is different from the data transmitted in the first communication connection. Specifically, the data amount of the data transmitted in the first communication connection is smaller than the data amount of the data transmitted in the second communication connection, and the content of the data transmitted in the first communication connection is different from the content of the data transmitted in the second communication connection.
For example, identification information and other instruction data of the first electronic device are mainly transmitted in the first communication connection, while service data packets, such as video data or document data, between the first electronic device and the second electronic device are mainly transmitted in the second communication connection.
In addition, when the second electronic device is close to the first electronic device and within the communication range corresponding to the first communication connection, as shown in fig. 2, the second electronic device establishes a first communication connection with the first electronic device, for example, the second electronic device establishes a communication connection with the first electronic device based on near field communication NFC (Near Field Communication), and of course, a communication chip based on NFC is configured in the first electronic device; after that, after the second electronic device obtains the identification information of the first electronic device through the first communication connection, the second electronic device establishes a second communication connection, such as a bluetooth connection or a WiFi connection, with the first electronic device according to at least the identification information, so that data, such as a corresponding service data packet, can be transmitted between the second electronic device and the first electronic device through the second communication connection, at this time, the second electronic device may be unchanged in location or may be appropriately far away from the first electronic device, and the distance between the second electronic device and the first electronic device may exceed a communication distance threshold corresponding to the first communication connection, that is, the second electronic device may not be in a communication range corresponding to the first communication connection of the first electronic device, but the second electronic device is definitely in a communication range corresponding to the second communication connection of the first electronic device, as shown in fig. 3.
Taking a first electronic device as a notebook computer and taking a second electronic device as a mobile phone as an example, an NFC chip is pre-configured on the notebook computer, and the notebook computer detects whether an update condition corresponding to the UUID is met in real time, for example, whether the number of times the UUID is read by other devices exceeds a limit or whether the update time of the UUID is overtime, and the like, and when the update condition corresponding to the UUID is met, the notebook computer updates the UUID once. Based on the method, when the mobile phone is close to the notebook computer and is in the communication range of the NFC chip configured on the notebook computer, NFC-based communication connection is established between the mobile phone and the computer, based on the NFC-based communication connection, the mobile phone obtains the latest UUID of the computer, then the mobile phone can establish Bluetooth connection with the computer at least according to the UUID, and after the Bluetooth connection is established, data packets such as videos or documents can be transmitted between the mobile phone and the computer.
In one implementation, in the first communication connection, the first electronic device further sends device information of the first electronic device, such as a communication address in the first electronic device for implementing the second communication connection, such as a bluetooth address or a WiFi address, etc., a device code of the first electronic device, such as a computer serial number SN (Serial Number), etc.; based on this, the second electronic device obtains the device information of the first electronic device through the first communication connection while obtaining the identification information through the first communication connection, and thereafter, the second electronic device can establish the second communication connection with the first electronic device using the identification information together with the device information.
Taking a first electronic device as a notebook computer and taking a second electronic device as a mobile phone as an example, an NFC chip is pre-configured on the notebook computer, and the notebook computer detects whether an update condition corresponding to the UUID is met in real time, for example, whether the number of times the UUID is read by other devices exceeds a limit or whether the update time of the UUID is overtime, and the like, and when the update condition corresponding to the UUID is met, the notebook computer updates the UUID once. Based on the method, when the mobile phone approaches the notebook computer until the mobile phone is in the communication range of the NFC chip configured on the notebook computer, NFC-based communication connection is established between the mobile phone and the computer, based on the NFC-based communication connection, the mobile phone obtains the latest UUID of the computer and the Bluetooth address and SN of the computer, then the mobile phone can establish Bluetooth connection with the computer according to the UUID, the Bluetooth address and the SN, and after the Bluetooth connection is established, data packets such as videos or documents can be transmitted between the mobile phone and the computer.
In one implementation, after step 102, the method in this embodiment may further include the following steps, as shown in fig. 4:
step 103: the identification information is written into a first communication component of the first electronic device.
The first communication component may be a component in the first electronic device that implements the first communication connection, such as an NFC chip, and specifically, the first communication component establishes a first communication connection with the second electronic device when the second electronic device meets a connection condition, based on which, after the updated identification information is written in the first electronic device and the updated identification information is written in the first communication component, the identification information in the first communication component can be obtained by the second electronic device that has already established the first communication connection through the first communication connection, and after the second electronic device obtains the identification information in the first communication component, a second communication connection with the second communication component in the first electronic device may be established, where the second communication component is a component that implements the second communication connection, such as a bluetooth or WiFi module.
As shown in fig. 5, the first electronic device is configured with a first communication component and a second communication component, where when a connection condition corresponding to the first communication component is satisfied between the second electronic device and the first electronic device, the first communication component establishes a first communication connection with the second electronic device, at this time, the second electronic device may obtain, using the first communication connection established by the first communication component, identification information written in the first communication component and updated last time, and may of course also obtain device information to the first electronic device, such as a communication address of the second communication component and a serial number of the first electronic device, and then, the second electronic device may establish a second communication connection with the first electronic device according to the information obtained by the first communication connection, and based on this, data such as video may be transmitted between the first electronic device and the second electronic device.
Taking a first electronic device as a notebook computer and taking a second electronic device as a mobile phone as an example, an NFC chip and a Bluetooth module are pre-configured on the notebook computer, and the notebook computer detects whether update conditions corresponding to UUIDs are met in real time, such as whether the times of reading the UUIDs by other devices exceed the limit or whether the update time of the UUIDs is overtime, and the like, when the update conditions corresponding to the UUIDs are met, the notebook computer updates the UUIDs once, and writes the updated UUIDs into the NFC chip. Based on the information, the mobile phone can be close to the notebook computer until the mobile phone is in the communication range of the NFC chip configured on the notebook computer, NFC-based communication connection is established between the mobile phone and the computer, at the moment, the latest UUID written in the NFC chip can be read by the mobile phone, of course, the mobile phone can also read the information such as the Bluetooth address and the SN of the computer through the NFC-based communication connection, then the mobile phone can establish Bluetooth connection with the computer according to the UUID, the Bluetooth address and the SN, and after the Bluetooth connection is established, data packets such as videos or documents can be transmitted between the mobile phone and the computer.
In a specific implementation, step 103 may be implemented when writing the identification information into the first communication component, specifically by:
firstly, creating a target process corresponding to the identification information, and then writing the identification information into a first communication component of the first electronic device by utilizing the target process corresponding to the identification information.
For example, a bluetooth service process corresponding to the UUID may be established first, and then the updated UUID may be written into the NFC chip by using the bluetooth service process.
Further, in the case where it is detected that the identification information satisfies the update condition, it is necessary to delete the target process corresponding to the identification information in addition to executing step 102 to update the identification information.
That is, in this embodiment, after the identification information is updated, the identification information is written into the first communication component through the established target process, and when the identification information needs to be updated again, the previously established target process is deleted, and after the identification information is updated again, the corresponding target process is re-established to write the updated identification information into the first communication component again.
For example, taking a first electronic device as a notebook computer and taking a second electronic device as a mobile phone as an example, an NFC chip and a bluetooth module are pre-configured on the notebook computer, and the notebook computer detects in real time whether an update condition corresponding to the UUID is satisfied, for example, whether the number of times the UUID is read by other devices exceeds a limit or whether the update duration of the UUID is overtime, etc., when the update condition corresponding to the UUID is satisfied, the notebook computer updates the UUID once, and creates a bluetooth service process, so as to write the updated UUID into the NFC chip, and when the notebook computer detects again that the update condition corresponding to the UUID is satisfied, closes the previously created bluetooth service process while re-updating the UUID, re-creates the bluetooth service process, and writes the updated UUID into the NFC chip. Based on the information, the mobile phone can be close to the notebook computer until the mobile phone is in the communication range of the NFC chip configured on the notebook computer, NFC-based communication connection is established between the mobile phone and the computer, at the moment, the latest UUID written in the NFC chip can be read by the mobile phone, of course, the mobile phone can also read the information such as the Bluetooth address and the SN of the computer through the NFC-based communication connection, then the mobile phone can establish Bluetooth connection with the computer according to the UUID, the Bluetooth address and the SN, and after the Bluetooth connection is established, data packets such as videos or documents can be transmitted between the mobile phone and the computer.
Referring to fig. 6, a schematic structural diagram of a processing apparatus according to a second embodiment of the present application may be configured in a first electronic device capable of performing data processing and data transmission, such as a mobile phone, a notebook, or a pad. The technical scheme in the embodiment is mainly used for improving the safety of data transmission of the electronic equipment.
Specifically, the apparatus in this embodiment may include the following units:
a condition detection unit 601 for detecting whether an update condition is satisfied in the case where the identification information is a first value;
an identification updating unit 602, configured to update the identification information to the obtained second value if the condition detecting unit 601 detects that the update condition is satisfied;
the identification information is information representing the first electronic equipment, and the identification information can be acquired by the second electronic equipment through the first communication connection to establish second communication connection with the first electronic equipment.
As can be seen from the above technical solution, in the processing apparatus according to the second embodiment of the present application, whether the update condition corresponding to the identification information representing the electronic device is satisfied is detected, so that when the update condition is satisfied, the identification information is updated from the first value to the obtained second value, and based on this, the identification information can establish the second communication connection with the electronic device after being obtained by the other electronic device through the first communication connection. Therefore, compared with the technical scheme that the fixation of the identification information of the electronic equipment can cause potential safety hazards in data transmission, in the embodiment, the value of the identification information is continuously updated by detecting whether the updating condition corresponding to the identification information is met or not in real time, so that even if the identification information is reversely acquired, the identification information reversely acquired is invalid because the identification information is updated, and effective communication connection is not established because the identification information is reversely acquired, thereby avoiding the potential safety hazards in data transmission and improving the safety of data transmission.
In one implementation, the first communication connection is established if the first electronic device and the second electronic device satisfy a connection condition; the connection conditions include: the second electronic device is present in a communication range corresponding to the first communication connection of the first electronic device;
and in the first communication connection, the first electronic device at least sends the identification information, so that the second electronic device establishes the second communication connection at least according to the identification information after obtaining the identification information, and data transmitted in the second communication connection is different from data transmitted in the first communication connection.
In one implementation, the communication range of the second communication connection is greater than the communication range of the first communication connection.
Optionally, in the first communication connection, the first electronic device further sends device information of the first electronic device, so that the second electronic device establishes a second communication connection with the first electronic device by using the identification information and the device information after obtaining the device information of the first electronic device.
In one implementation, the identifier updating unit 602 is further configured to, after updating the identifier information to the obtained second value, further: writing the identification information into a first communication component of the first electronic device;
the first communication component establishes a first communication connection with the second electronic device under the condition that the first communication component and the second electronic device meet the connection condition, so that identification information in the first communication component is acquired by the second electronic device through the first communication connection, and then a second communication connection with the second communication component in the first electronic device is established.
Specifically, when writing the identification information into the first communication component of the first electronic device, the identification updating unit 602 creates a target process corresponding to the identification information, and then writes the identification information into the first communication component of the first electronic device by using the target process corresponding to the identification information.
Further, the identifier updating unit 602 is further configured to, after writing the identifier information into the first communication component of the first electronic device: and deleting the target process corresponding to the identification information under the condition that the identification information is detected to meet the updating condition.
Optionally, the updating condition includes: the number of times the identification information is obtained after the last time the identification information was updated is greater than or equal to a number of times threshold and/or the time period from the interval when the identification information was last updated is greater than or equal to a time period threshold.
In one implementation, the first electronic device may record the number of times the identification information is obtained by other devices, such as the second electronic device, by configuring a counter, and in addition, the timing may be implemented by configuring a timer. Based on this, the condition detection unit 601 continuously detects the number of times output by the counter and/or the duration output by the timer to detect whether the update condition is satisfied.

the identification information is information representing the electronic equipment, and the identification information can be acquired by other equipment through the first communication connection to establish a second communication connection with the electronic equipment.
Further, the electronic device in this embodiment may be further configured with a counter and a timer, based on which the processing component 703 may detect whether the update condition is satisfied by reading the number of times output by the counter and/or the duration output by the timer, where the update condition may be: the number of times the identification information is obtained after the last identification information is updated is greater than or equal to a number of times threshold and/or the time period from the time of the last interval when the identification information is updated is greater than or equal to a time period threshold.
As can be seen from the above technical solution, in the electronic device according to the third embodiment of the present application, whether the update condition corresponding to the identification information representing the electronic device is satisfied is detected, so that when the update condition is satisfied, the identification information is updated from the first value to the obtained second value, and based on this, the identification information, after being obtained by other electronic devices through the first communication connection, can establish the second communication connection with the electronic device. Therefore, compared with the technical scheme that the fixation of the identification information of the electronic equipment can cause potential safety hazards in data transmission, in the embodiment, the value of the identification information is continuously updated by detecting whether the updating condition corresponding to the identification information is met or not in real time, so that even if the identification information is reversely acquired, the identification information reversely acquired is invalid because the identification information is updated, and effective communication connection is not established because the identification information is reversely acquired, thereby avoiding the potential safety hazards in data transmission and improving the safety of data transmission.
It should be noted that, the specific implementation of each component in this embodiment may refer to the corresponding content in the foregoing, which is not described in detail herein.
Taking a first electronic device as a notebook and a second electronic device as a mobile phone as an example, the following describes the technical scheme of the application in detail:
in the application, dynamic data generation and transmission are realized by using a built-in NFC SWP (Single Wire Protocol) SIM (Subscriber Identity Module) card, and the data security problem is effectively avoided by combining software realization of Bluetooth service, specifically as follows:
firstly, the NFC SWP SIM card is placed inside the notebook computer, as shown in fig. 8, the NFC SWP SIM card can be arranged in the notebook computer at a position close to the edge, such as an edge position close to the keyboard and the touch area on the C surface, so that the risk that the static NFC device attached to the surface layer of the computer is easy to remove and forge is avoided;
secondly, bluetooth RFComm Service UUID can be dynamically generated and written into the NFC SWP SIM card in the operation process of the notebook computer, and is updated periodically, the mobile phone terminal can dynamically obtain Bluetooth RFComm Service UUID by scanning NFC when data transmission is needed, and Bluetooth RFComm connection between the mobile phone terminal and the computer is established through the Bluetooth module of the mobile phone terminal so as to facilitate data transmission, and the situation that Bluetooth RFComm Service UUID is randomly transmitted after reverse engineering is obtained is avoided.
Therefore, in the application, the security problem that the data is randomly sent after Bluetooth RFComm Service UUID is reversed and the static NFC device is easy to replace is solved by arranging the NFC SWP SIM card in the computer end and dynamically generating Bluetooth RFComm Service UUID.
In conjunction with the respective architecture diagrams of the mobile phone and the computer shown in fig. 9, the following is a flow of UUID processing through Bluetooth service in the computer, as shown in fig. 10:
firstly, monitoring whether a Bluetooth service is started or not in a computer, and detecting whether an update condition of a UUID is met or not under the condition that the Bluetooth service is started, namely judging whether the UUID is out of date and needs to be updated or not;
under the condition that the Bluetooth service is not started or the UUID is out of date, regenerating the UUID in the computer and creating a Bluetooth service process, writing the UUID into a NFC SWP SIM card arranged in the computer end through the Bluetooth service process, waiting for the mobile phone to be connected with the computer, and continuously detecting whether the UUID is out of date;
under the condition that the mobile phone reads UUID in the computer and establishes Bluetooth connection and the UUID is not expired, the mobile phone and the computer can transmit data such as video through the Bluetooth connection.
