Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The file transmission method and device provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
The file transmission method provided by the embodiment of the application can be applied to the first electronic equipment, and the first electronic equipment can perform visible Light wireless communication (LiFi).
Visible light wireless communication may also be called as LiFi technology, and based on the LiFi technology, wireless transmission of data can be performed by using visible light spectrum.
As shown in fig. 1, the file transmission method provided by the embodiment of the present application includes:
step 101, responding to the input of the selected target file, and transmitting a first optical signal;
step 102, a LiFi connection with the second electronic equipment is established in response to a second optical signal sent by the second electronic equipment, wherein the second optical signal is generated by the second electronic equipment in response to the first optical signal;
and step 103, transmitting the target file to the second electronic device based on the LiFi connection.
In this embodiment, the target file may be a video, a picture, or a document, which is not specifically limited herein.
And combining some application scenes, and under the condition that a file selection interface is displayed in the first electronic equipment, a user can select a file to be transmitted in the file selection interface.
For example, a gallery interface may be displayed in the first electronic device, and a user may select a thumbnail of a picture in the gallery interface. For another example, in the document management interface in the first electronic device, information of a plurality of documents may be displayed, and the user may select a document in the document management interface.
The above gallery interface with thumbnail images displayed or the document management interface with document information displayed can be regarded as a file selection interface. And the picture or document selected by the user can be regarded as the target file.
In the event that a user selection input to the target file is received, the first electronic device may transmit a first optical signal in response to the selection input. In other words, in step 101, the first electronic device may send the first optical signal in response to an input selecting the target file.
For example, when receiving a selection input of the user to the target file, the first electronic device may control the light emitting unit such as the display screen, the light emitting diode (Light Emitting Diode, LED) breathing lamp, or the LED light supplement lamp to be turned on or off according to a preset frequency in response to the selection input, so as to implement the transmission of the first optical signal.
In other words, the first optical signal may be a blinking optical signal. Similarly, the second optical signal and the optical signal for transmitting the target document hereinafter may be both blinking optical signals.
For example, the first electronic device may include a first display screen, and the first display screen may be an LED display screen. And the first optical signal can be sent by controlling all or part of LED modules in the LED display screen to carry out on-off change according to the preset frequency.
Of course, the first display is merely illustrative, and in practical application, the first display may be an Organic Light-Emitting Diode (OLED) display or other types of displays, which is not limited herein, and can implement transmission of optical signals.
The first optical signal transmitted by the first electronic device may be received by the second electronic device. For example, the second electronic device may be a mobile terminal or a personal computer or the like integrated with the LiFi signal receiver, which is not particularly limited herein.
For example, the second electronic device may be of a similar construction to the first electronic device, i.e. the second electronic device may comprise a light emitting unit capable of being turned on and off at a preset frequency. Meanwhile, the second electronic device may also include a LiFi signal receiver for LiFi signal reception. In this way, the second electronic device can not only receive the first optical signal but also transmit the second optical signal through the light emitting unit in response to the first optical signal.
For another example, the second electronic device may include a second display screen, and the LiFi signal receiver of the second electronic device may be disposed on a surface (hereinafter referred to as a front surface) where the second display screen of the second electronic device is located. The second electronic device can receive the first optical signal through the LiFi signal receiver on one hand under the condition that the front surface faces the first electronic device; on the other hand, the second optical signal may be transmitted by blinking through the second display screen.
Of course, in practical applications, the second electronic device is not limited to the structure in the above example. For example, the second electronic device may have a LiFi signal receiver and a LiFi signal transmitter, and may be capable of transmitting and receiving LiFi signals without including the second display screen.
Alternatively, the second electronic device may include a second display screen, but may not need to transmit the LiFi signal or the like by controlling the second display screen to blink, but transmit the LiFi signal by the LED breathing lamp or the LED light supplement lamp.
In general, the second electronic device may be capable of receiving and transmitting the LiFi signal, and the specific receiving and transmitting manner may not be limited herein.
In step 102, the first electronic device may receive the second optical signal sent by the second electronic device, so as to establish a LiFi connection with the second electronic device.
For example, the first optical signal may be broadcast information for requesting establishment of a LiFi connection. The second electronic device, upon receiving the first optical signal, may send a second optical signal in response to the first optical signal to agree to establish a LiFi connection with the first electronic device.
After receiving the second optical signal, the first electronic device may establish a LiFi connection with the second electronic device.
On the basis, the first electronic device and the second electronic device can transmit files through LiFi connection. Specifically, in this embodiment, the first electronic device may transmit the above-mentioned target file to the second electronic device based on the LiFi connection.
It is easy to understand that, in the process of transmitting the target file to the second electronic device based on the LiFi connection, the first electronic device may also transmit the target file through a blinking light signal with a preset frequency by changing the on/off of the light emitting unit, such as the first display screen, the LED breathing lamp, or the LED light supplementing lamp.
In the process of transmitting the target file based on LiFi connection, the transmission of the target file can be maintained through the flashing light signal sent by the first electronic equipment, the process can not be influenced by factors such as network signals, and the reliability of the file transmission process can be effectively ensured.
According to the file transmission method provided by the embodiment of the application, the first electronic equipment responds to the selected target file, sends the first optical signal, establishes LiFi connection with the second electronic equipment under the condition that the second electronic equipment receives the second optical signal sent by the second electronic equipment responding to the first optical signal, and can transmit the target file to the second electronic equipment based on LiFi connection. According to the embodiment of the application, the file is transmitted through LiFi connection, the file transmission process is not limited by network signals, and the reliability of the file transmission process is effectively improved.
In addition, the target file can be preselected by a user in advance, after the LiFi connection is established between the first electronic device and the second electronic device, the user can avoid further inputting related target file selection on the first display screen, and the interruption of LiFi connection caused by the fact that the user blocks the optical signal for a long time is effectively avoided, so that the stability and reliability of LiFi connection are effectively improved.
In one embodiment, the first electronic device includes a first display screen and a LiFi chip;
accordingly, in response to an input selecting the target file, transmitting the first optical signal may specifically include:
And responding to the input of the selection target file, and controlling the first display screen to send a first optical signal through the LiFi chip.
In this embodiment, the LiFi chip may be electrically connected to the first display screen, and may control the first display screen to be turned on and off according to a preset frequency to send an optical signal, so as to further implement data wireless transmission between the first electronic device and other electronic devices.
Specifically, the first electronic device may control the first display screen to send the first optical signal through the LiFi chip.
The first light signal obtained by the first display screen according to the preset frequency can be a relatively high-speed flashing light signal. In general, the flicker of the first light signal is relatively difficult to perceive by the human eye, and thus, the first light signal may be transmitted without affecting the user or with less impact on the user's vision.
Similarly, in the process of transmitting the target file, the blinking light signal used for transmitting the target file can also not influence the normal use of the first display screen by the user.
In one example, the LiFi chip can electrically connect all or part of the LED modules in the LED display screen. The LiFi chip can control the LED module connected with the point to flash through an electric signal, so that a first optical signal is sent.
Furthermore, it is easy to understand that, for the LiFi chip, the first display screen can be controlled to be turned on or off to obtain an optical signal, and the LiFi chip can also be used for processing a received optical signal.
For example, the received second optical signal may be processed by a LiFi chip. In the case where the LiFi chip determines that the second optical signal is generated by the second electronic device in response to the first optical signal, the first electronic device may establish a LiFi connection with the second electronic device.
In order to simplify the description, in the following embodiments, an explanation will be mainly given of an example in which the first electronic device transmits an optical signal by controlling the first display screen to be turned on and off.
In one example, the second electronic device may prompt the user through a second display screen or an acousto-optic prompting device in response to the first optical signal when receiving the first optical signal. In case an input is received indicating agreement to establish a LiFi connection, a second optical signal is further transmitted.
In another example, the second electronic device may also send the second optical signal directly upon receiving the first optical signal, so that the first electronic device can obtain information of the device with which the LiFi connection can currently be established.
In other words, the first optical signal may be self-identity information broadcasted by the first electronic device and status information that can perform LiFi connection at this time. In general, the information for LiFi communication interaction is carried by an optical signal, and thus, the first electronic device obtains the information of the device capable of performing LiFi communication with the first electronic device. The second electronic device may send a second optical signal to the first electronic device in response to the first optical signal after receiving the first optical signal to notify the first electronic device that LiFi communication may be performed therewith.
The process of receiving the input of the user by the second electronic device to agree to the transmission of the target file may also be performed in the subsequent interaction process. The interaction process may be described in detail in the examples of embodiments below.
Generally, the first electronic device determines the target file to be transmitted, and if the second electronic device establishes a LiFi connection, the first electronic device may transmit the target file.
In some application scenarios, the transmission process of the target file may require a longer transmission time, and the relative position between the first electronic device and the second electronic device is changed more, which may result in poor stability of the transmission process.
In order to facilitate the user to transfer the target file through the LiFi connection in a suitable operation state, and ensure the stability of the transfer process of the target file, in one embodiment, the transferring the target file to the second electronic device based on the LiFi connection in step 103 includes:
receiving a first input;
in response to the first input, the target file is transmitted to the second electronic device based on the LiFi connection.
In combination with an example of an application scenario, the first electronic device includes a first display screen, and the second electronic device includes a second display screen. The first electronic device and the second electronic device may be lifei connection that is set up in a state where the display screen is arranged opposite to each other and is in a bright screen state.
Specifically, in this example of an application scenario, the first electronic device sends an optical signal by controlling the first display screen to blink, and may receive the optical signal sent by the second electronic device through a LiFi signal receiver disposed on the front side. The second electronic device may also implement a process of receiving and transmitting an optical signal as shown in the first electronic device.
When the first electronic device and the second electronic device are in a state that the display screens are oppositely arranged, optical signal interaction can be conducted between the first electronic device and the second electronic device. And the light signal may be generated with the display screen in a bright state. Thus, from a visual point of view, the first electronic device and the second electronic device may be a LiFi connection established in a state in which the display screen is on.
In this case, in order to simplify the input operation of the user, the first input may correspond to a tap operation of the back shell of the first electronic device by the user, a shake operation of the first electronic device, or the like.
For example, in a case where the first electronic device is opposite to the second electronic device with a bright screen, the user may double-click the back shell of the first electronic device, and the first electronic device may detect a first input of the double-click back shell through the acceleration sensor, and may start to send the target file to the second electronic device in response to the first input.
Alternatively, the user may shake the first electronic device, where the LiFi connection is typically based on wireless communication of visible light, and the shake of the first electronic device within a certain range may ensure that the emitted light signal is continuously received by the second electronic device.
And the first electronic device may detect a shake input of the user through the acceleration sensor and, in response to the shake input, start transmitting the target file to the second electronic device.
Therefore, in the operation process corresponding to the first input, a user does not need to stretch fingers or other operation components between the first electronic equipment and the second electronic equipment, and the comparison results in shielding of visible light for LiFi communication, so that the stability of LiFi connection is ensured.
In addition, in combination with other application scenarios, in the process of sending the target file to the second electronic device through the first electronic device, the user can place the second electronic device at a table or the like and hold the first electronic device. Under the condition that the relative positions of the electronic devices are stable and the user is in an appropriate operation gesture for the electronic devices, the first input is carried out on the first electronic device to transmit the target file, so that the user does not need to adjust the gesture of holding the first electronic device excessively in the transmission process of the target file.
Of course, the above corresponding posture and positional relationships when the first electronic device and the second electronic device maintain the LiFi connection are only some examples. In practical application, the posture and the position relationship between the first electronic device and the second electronic device can be determined according to the installation position of the LiFi signal transceiver on the second electronic device.
The first input may be an input on the first display screen or the like. For example, in the case where the first electronic device establishes a LiFi connection with the second electronic device, a corresponding operation control, such as an icon control named "start transmission", may be displayed in the first display screen. And under the condition that a first input such as clicking input of an operation control by a user is received, the LiFi connection can be used for transmitting the target file to the second electronic equipment.
In one embodiment, when the first electronic device starts to transmit the target file to the second electronic device, at one end of the second electronic device, a corresponding operation control, for example, an icon control named "accept receive" and the like, may also be displayed on the second display screen. Upon receiving input of the icon control "accept to receive", the second electronic device begins to receive and store the target file described above.
Of course, an icon control named "reject accept" may also be displayed on the second electronic device. In the event that input is received to the "reject accept" icon control, the second electronic device may not receive the target file described above.
In some application scenarios, by reasonably setting the installation position of the LiFi signal receiver, a user can avoid blocking the light signal when operating the first display screen or the second display screen as much as possible when the finger or the like of the user.
For example, the LiFi signal receiver may be disposed above the first display screen, and in general, when the user operates the icon control, shielding of the LiFi signal receiver may be avoided.
Of course, generally, when the first electronic device and the second electronic device establish the LiFi connection, the light signal is temporarily blocked, which may be considered to be a decrease in intensity of the light signal caused by the poor communication state to some extent, so that the transmission of the whole target file is not affected by the temporary blocking.
In other words, in general, the operation of the user on the first display screen or the second display screen may not affect or affect less the reliability of the transmission process of the above-mentioned target file.
In order to improve the security of the target file transmission, in one embodiment, the above step 103, before transmitting the target file to the second electronic device based on the LiFi connection, the file transmission method may further include:
acquiring encryption information of a target file and optical signal frequency adopted by LiFi connection;
transmitting the target file to the second electronic device based on the LiFi connection, comprising:
and transmitting the target file to the second electronic device based on the LiFi connection under the condition that the encryption information is matched with the frequency of the optical signal.
In this embodiment, the target file may have corresponding encryption information, and the encryption information may be used to represent an encryption state or an encryption level of the target file. For example, the encryption status may refer to whether the target file is an encrypted file.
The encryption information of the target file may be preset or manually set by the user, which is not specifically limited herein.
In one example, the encryption information for the target file may be automatically determined for the target file according to a preset rule. For example, the target file may be a file of a picture type, and when the first electronic device recognizes the target file as a certificate picture based on the picture recognition model, the encryption information of the target file may be indicated as an "encrypted file". And when the object file is recognized as a landscape picture, the encrypted information of the object file may be indicated as an "unencrypted file".
In one example, the encryption information of the target file may be manually set by the user. For example, the target file may be a document type file. The user can manually set the encryption level of the target file. The encryption level may be set to "secret", and "normal" according to the degree of importance.
Of course, the above is merely some examples of the encryption information of the target file, and in practical applications, the content indicated by the encryption information, or a specific determination manner may be set as required.
The frequency of the optical signal employed by the first electronic device for transmitting the target file may be varied. These frequencies may be preset.
For example, the first electronic device may perform transmission of the target file through the optical signals of the first preset frequency and the second preset frequency.
It is to be readily understood that in the present embodiment, the optical signal frequency may refer to a frequency of an optical signal, specifically, may refer to a blinking frequency of an optical signal, or refer to a light emitting unit, such as an on-off frequency of a first display screen, for a user to transmit an optical signal.
In addition, in this embodiment, a preset correspondence may be established between the encrypted information of the target file and the optical signal frequency used for the LiFi connection of the first electronic device.
For example, the encrypted information includes an "encrypted file" or an "unencrypted file", and the above-mentioned preset correspondence may mean that the "unencrypted file" is transmitted by an optical signal of a first preset frequency, and the "encrypted file" is transmitted by an optical signal of a second preset frequency.
In this embodiment, before the first electronic device transmits the target file, the first electronic device may acquire the optical signal frequency used for connecting the encryption information of the target file and the LiFi. And when the encryption information of the target file is matched with the frequency of the optical signal, the first electronic device transmits the target file to the second electronic device based on LiFi connection.
Therefore, the transmission process of the target file can be limited by the optical signal frequency, that is, the target file is transmitted under the condition that the optical signal frequency is matched with the encryption information of the target file, so that the transmission safety of the target file can be ensured to a certain extent.
Of course, in some possible embodiments, the above-mentioned optical signal frequency may also be the frequency of the light. For example, different colors of light may have different frequencies. And when transmitting the target file of specific different encrypted information, different color optical signals can be used.
In order to enable the first electronic device to transmit the target file with different encryption information, in an embodiment, before transmitting the target file to the second electronic device based on the LiFi connection, the file transmission method may include:
receiving a second input;
in response to the second input, the frequency of the optical signal employed by the LiFi connection is changed.
In this embodiment, the second input may be a tap or shake input corresponding to the user to the first electronic device; alternatively, the input may be a voice input, a gesture input, or the like; alternatively, the input may be a click, a slide, or the like on the first display screen, which may not be particularly limited herein.
In general, the specific manner of operation of the second input may be distinguished from the manner of operation of the first input described above. For example, the first input may be an input to double click on the back shell, the second input may be an input to single click on the back shell, and so on.
In combination with an application scenario, under the condition that the target file fails to be transmitted normally, a user can knock the back shell of the first electronic device, so that the first electronic device can replace the optical signal frequency adopted by LiFi connection, and the target file with corresponding encryption information is transmitted.
In one example, there may be a correspondence between the manner of operation of the second input and the frequency of the optical signal. For example, when the user shakes the first electronic device in the left-right direction, the first electronic device may determine the frequency of the optical signal employed for LiFi connection as the first preset frequency in response to the shake operation. When the user continuously taps the back shell three times, the first electronic device can respond to the operation of the three taps to determine the frequency of the optical signal adopted by the LiFi connection as a second preset frequency.
In another example, the second electronic device may also switch the frequency of the optical signal in response to a second input of some preset operating mode, for example, in response to a single tap of the back shell. That is, the frequency of the optical signal can be switched in a specific order once for each strike of the back shell.
As can be seen from the above examples, by setting a specific operation mode corresponding to the second input for triggering the light signal frequency switching, diversified operation habits of users can be satisfied. Meanwhile, the specific operation mode corresponding to the second input can be used as an unlocking mode for triggering the optical signal frequency, and the security of the transmission of the target file can be improved through setting the second input.
Optionally, to further improve the security of the target file transmission, the replacing the optical signal frequency used for the LiFi connection in response to the second input may specifically include:
acquiring biometric information in response to the second input;
and under the condition that the biological identification information is matched with the preset biological identification information, replacing the optical signal frequency adopted by LiFi connection.
For example, the second input may be a touch input of the user to a fingerprint recognition module in the first electronic device, or a proximity action in front of a camera with palm print information or iris information collection function, etc.
As shown above, in the LiFi communication process, the scintillation light information is blocked briefly, and the LiFi connection can still be maintained. Therefore, for the first electronic device with the camera on the front for iris information collection, the user can still turn the first electronic device to the face of the user, so that the first electronic device can collect iris information.
It is easy to understand that the first electronic device may have pre-stored therein the biometric information of the user, i.e. the preset biometric information described above. When the biometric information obtained by the first electronic device in response to the second input matches the preset biometric information, the frequency of the optical signal used for the LiFi connection may be changed.
Therefore, in this embodiment, the optical signal frequency for LiFi communication is switched based on the biometric information, so that the encrypted file or the file with a higher encryption level can be effectively prevented from being acquired by an illegal user, and the security of the target file is improved.
As indicated above, the above-mentioned optical signals have a relatively high flicker frequency, which is often difficult to identify by the naked eye of a user. Thus, to facilitate the user to be able to learn about the replacement of the frequency of the optical signal employed by the first electronic device, in one embodiment, after receiving the second input, the file transfer method may further include:
in response to the second input, changing the color of the optical signal used by the LiFi connection, the color of the optical signal matching the frequency of the optical signal used by the LiFi connection.
For example, the first electronic device transmits an optical signal to transmit the target file through the first display screen. Meanwhile, the first electronic device can adopt optical signals with two frequencies, namely a first preset frequency and a second preset frequency to realize LiFi connection.
When the first electronic device adopts the light signal with the first preset frequency, the color of the first display screen can be enabled to be displayed as red. And under the condition that the second input is received so that the second electronic device adopts the light signal with the second preset frequency, the color of the first display screen can be displayed as blue.
In other words, when the first electronic device performs LiFi connection with a light signal frequency, the first display screen can emit light with a matching color.
Therefore, the user can intuitively know the frequency conversion of the optical signal adopted by the first electronic equipment, and redundant operation of the user on the first electronic equipment is avoided.
Of course, the above change in display color of the first display screen is merely an exemplary illustration. In practical application, display colors corresponding to the frequencies of the optical signals adopted by different LiFi connections can be set according to practical requirements.
Further alternatively, the above-mentioned optical signal frequency and the display color may not have a fixed correspondence, and the change of the optical signal frequency may be indicated by the change of the color.
In addition, as shown above, in the LiFi connection process, the first electronic device may not only transmit the optical signal through the first display screen, but also transmit the optical signal using a light emitting unit of a type such as an LED breathing lamp. Correspondingly, when the frequency of the light signal used for LiFi connection is changed, the color of the light signal of the light emitting unit such as the LED breathing lamp can be switched.
The file transmission method provided by the embodiment of the application is described below with reference to a specific application example.
As shown in fig. 2, in this specific application example, mobile phone a (corresponding to the first electronic device) and mobile phone B (corresponding to the second electronic device) may perform LiFi communication. Accordingly, the file transfer method may include:
step 201, selecting a file to be transmitted from a file interface of the mobile phone A;
specifically, the mobile phone a may receive a selection input from a user when a file interface is displayed, and may determine a target file to be transmitted in response to the selection input from the user.
Step 202, judging whether the mobile phone A and the mobile phone B are opposite in screen brightness, if yes, executing step 203, and if no, not triggering file transmission;
in this step, the mobile phone a and the mobile phone B are opposite to each other in bright screen, and can be considered as a visual expression form for establishing LiFi connection.
In particular, the flicker frequency of the optical signal employed for LiFi connection is often difficult to perceive by the human eye. However, the LiFi technology generally adopts visible light wireless communication, so that when the mobile phone a and the mobile phone B are on the bright screen, the two can realize reliable LiFi connection.
Step 203, the mobile phone B establishes a connection with the mobile phone a by identifying a spectrum signal with a specific frequency sent by the screen of the mobile phone a;
As described above, the process of establishing the LiFi connection between the mobile phone a and the mobile phone B may be that the mobile phone a receives the selection input of the target file and sends the first optical signal. In the case of receiving the first optical signal, the mobile phone B may send a second optical signal in response to the first optical signal, so as to indicate that the LiFi connection is agreed to be established with the mobile phone a. And under the condition that the first electronic equipment receives the second optical signal, the first electronic equipment can correspondingly establish LiFi connection with the second electronic equipment according to the second optical signal.
Step 204, the mobile phone a uses an acceleration sensor to determine whether to double click the back; if yes, go to step 205; if not, not triggering file transmission;
this step may be considered as a process of determining whether the mobile phone a receives the first input described above.
Step 205, mobile phone a starts file transmission;
i.e. mobile a starts to send the target file to mobile B based on the LiFi connection.
Step 206, the mobile phone B pops up an acceptance prompt box;
for example, "do it receive a file from a? The prompt text of "and two operation controls named" reject "and" accept "are displayed.
Step 207, judging whether the mobile phone B receives the target file, if yes, transmitting the target file until the target file is successfully transmitted; if not, the file transmission fails.
And judging whether the actual B is received, namely judging which operation control is input by the user, namely, the user is specific to the two operation controls of 'reject' and 'accept'. If the user clicks "reject", the file transfer fails. If the user clicks on accept, the target file is transmitted until the target file is successfully transmitted.
In order to provide security for file transfer, based on the above specific application example, the step 204 may specifically include:
the mobile phone A senses whether the back is knocked through the acceleration sensor, if the back is knocked once, the color of the screen light is changed, another frequency light signal is converted, the encryption transmission mode is changed, the encrypted file can be transmitted only under the color light, and otherwise, the encrypted file cannot be transmitted.
Based on the above specific application examples, in the embodiment of the present application, an interaction manner of rapidly transmitting files between electronic devices may be implemented based on the LiFi technology. The LiFi technology is applied, so that the convenience and the rapidness are high, the operation path of file transmission by a user is shortened, and the convenience of file transmission is greatly improved. The target file is transmitted through the simple tapping gesture, the shielding of visible light used in LiFi communication can be avoided, meanwhile, the tapping gesture is similar to the dumping action, the interaction operation can be similar to dumping of the target file from one electronic device to another electronic device, and the operation experience of a user is improved. In addition, the color difference of the screen light can be utilized, so that the security is ensured, and meanwhile, a relatively visual encrypted file transmission mode is provided.
