Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example one

An embodiment of the present invention provides a data transmission method, as shown in fig. 1, which is applied to a data transmission method at a first terminal side, and the method may include:

s101, determining that the first mode is a data transmission mode, wherein the first mode is a mode allowing data stored in the storage area to be transmitted to the second terminal.

The data transmission method provided by the embodiment of the invention is suitable for a scene that the first terminal cannot perform data transmission through the operation of a user on the touch screen due to the faults of the first terminal, such as damage of the touch screen, poor backlight of an LCD (liquid crystal display) and the like.

In the embodiment of the invention, the first terminal is preset with the first mode, the first mode can transmit the data of the first terminal on the premise of not operating the touch screen, and the first mode has the highest authority.

Optionally, the first terminal in the embodiment of the present invention may be a mobile phone, a tablet, or another communication device that can perform data transmission, and the embodiment of the present invention is not limited.

Optionally, in the embodiment of the present invention, the user may enter the first mode by inputting a preset key instruction or inputting biological information, which is specifically set according to an actual situation, and the embodiment of the present invention is not limited specifically.

Optionally, the preset key instruction in the embodiment of the present invention may be a combination key, for example: a combination of an upper key and a lower key of the first terminal, a combination of a power-on key and a lower key of the first terminal, etc., which are not limited in the embodiments of the present invention.

In the embodiment of the invention, the first mode and the normal starting mode of the first terminal share a preset identity information base, and the first mode of the first terminal comprises a first to-be-transmitted data list needing to be transmitted and corresponding to-be-transmitted data. The first mode of the first terminal stores first data to be transmitted in a storage area of the first terminal, and the first mode reads data from the storage of the storage area of the first terminal.

Optionally, the preset identity information base stores collected biometric information of the user or preset key combination information, which is specifically selected according to an actual situation, and the embodiment of the present invention is not limited specifically.

It should be noted that, in the embodiment of the present invention, the preset key instruction is obtained by the first terminal based on the user behavior. Specifically, a user operates keys on the first terminal to generate a first combined key instruction, and when the first combined key instruction is matched with a preset key combination in the first terminal, the first combined key is represented as a preset key instruction, that is, the first terminal receives the preset key instruction.

Further, in the embodiment of the present invention, when the key instruction received by the first terminal is different from the preset key instruction, the first terminal ends the operation of entering the first mode.

S102, when the mobile terminal is in the first mode, first identity authentication information is obtained, and authentication is carried out on the first identity authentication information.

Specifically, when the first terminal is in the first mode, the first identity authentication information needs to be acquired first to perform the validity authentication of the user.

In the embodiment of the invention, when the first terminal is in the first mode, the first terminal can prompt the user to input the first identity authentication information through the first prompt message.

Optionally, the first prompt message may include: voice prompt, charge indicator light prompt, and the like. For example, the user is prompted to enter the first mode by the color or on and off of an indicator lamp arranged on the front surface of the first terminal, and user validity authentication is required. Specifically, the first terminal prompts the user, which is not limited in the embodiment of the present invention.

Optionally, the first identity authentication information may include identity information representing the user, such as a fingerprint or a preset key combination.

It should be noted that the first identity authentication information acquired by the first terminal is identity information of the current user, and the current user identity information refers to identity information of a user currently using the first terminal for data transmission.

In the embodiment of the invention, after the first terminal receives the first identity authentication information, the first terminal judges the validity of the first identity authentication information by matching the first identity authentication information with the preset identity information base.

The biological feature information of the user in the embodiment of the present invention refers to some information that the self physiology of the user changes, wherein the biological feature may be a contraction in an auricle, a blood flow velocity, brain waves of a cerebral cortex, a fingerprint, face information, and the like. Thus, the predetermined identity information base may comprise a database of biometric information, such as fingerprints, that characterize the user.

Illustratively, the acquisition of the first identity authentication information is described by taking the example that the first terminal collects the user fingerprint information and the user face information. The first terminal can collect the fingerprint information through an HOME key arranged on the first terminal, and when a user places a finger on the HOME key on the first terminal, a sensor arranged on the position of the HOME key can detect the fingerprint information of the user. The first terminal can collect face information of the face of the user through a camera arranged on the first terminal. Specifically, under the condition that the front-facing camera exists, the first terminal can start the front-facing camera to perform information acquisition work of a current target object; under the condition that the front camera does not exist, the first terminal can start the rear camera to collect the face information of the current user.

In the embodiment of the present invention, when a user uses a first terminal without ADB function to perform data transmission, the first terminal needs to perform validity authentication on the user, and the data transmission method provided in the embodiment of the present invention can be adopted only when the user used is authenticated to be valid.

It is understood that in the embodiment of the present invention, since the user biometric information is a user with the same or similar characteristics, the possibility is very low. Therefore, the fingerprint features (fingerprint information) or the face features (face information) in the user biological feature information are not easy to be stolen or falsely used, so the confidentiality of the user legality authentication by adopting the user biological feature is very good.

Further, in the embodiment of the present invention, when the validity authentication of the first terminal to the user fails, that is, the user is authenticated to be illegal, the operation in the first mode is ended, for example, the first mode is exited.

Illustratively, the user inputs a correct combination key, the charging indicator light of the first terminal turns green, the user inputs an incorrect combination key, the charging indicator light of the first terminal turns red, after the charging indicator light of the first terminal turns green, the charging indicator light of the first terminal flashes to remind the user of inputting the first identity authentication information, and when the first terminal collects the first identity authentication information of the user, the charging indicator light of the first terminal stops flashing.

And S103, when the first identity authentication information is successfully authenticated, performing communication connection with the second terminal.

When the first terminal acquires the first identity authentication information, the first terminal needs to authenticate the legality of the user of the second terminal, and when the user of the second terminal is authenticated to be legal, the first terminal establishes communication connection with the second terminal.

In the embodiment of the invention, the first terminal can prompt whether the first identity authentication information is matched with the fourth identity authentication information in the preset identity information base through the second prompt information.

It should be noted that the fourth identity authentication information in the embodiment of the present invention is any identity information in a preset identity information base.

Optionally, the second prompt message may include: voice prompt, charge indicator light prompt, and the like.

Optionally, the first identity authentication information in the embodiment of the present invention may be biometric information of the user, or authentication information such as a preset key combination that can represent the identity of the second terminal, which is specifically selected according to an actual situation, and the embodiment of the present invention is not limited specifically.

It should be noted that, in the embodiment of the present invention, the first terminal prompts the user to input the first identity authentication information through the first prompt information, and then prompts the user whether to pass the validity authentication through the second prompt information, where the first prompt information and the second prompt information of the first terminal may be the same prompt information or different prompt information, for example: the first terminal can prompt a user to input first identity authentication information through the flickering of the charging indicator lamp, and prompt the user whether to pass the legality authentication or not through the green and red changing of the charging indicator lamp; the first terminal can also prompt the user to input the first identity authentication information through the flickering of the charging indicator lamp, and prompt the user whether to pass the validity authentication or not through the flickering times of the charging indicator lamp.

Exemplarily, when the charging indicator light of the first terminal is green, it indicates that the first identity authentication information matches the fourth identity authentication information; when the charging indicator light of the first terminal is red, it is indicated that the first identity authentication information is not matched with the fourth identity authentication information.

In the embodiment of the invention, the first terminal matches the acquired first user identity authentication with the fourth identity authentication information to complete the authentication of the first identity authentication information.

In the embodiment of the present invention, the fourth user authentication information and the first user authentication information may be biometric information of the same user.

It should be noted that the process of establishing a communication connection between the first terminal and the second terminal in the embodiment of the present invention may be a process of performing a network connection between the first terminal and the second terminal, and specifically, the first terminal and the second terminal may perform a wireless connection, so as to perform interaction between data of the two terminals through a wireless network connection.

Optionally, the Wireless network connection in the embodiment of the present invention may be Wireless technologies such as Wireless local area network (WIFI), Bluetooth (BT), and the like.

Preferably, the wireless network connection mode in the embodiment of the present invention may be bluetooth.

Further, in the embodiment of the present invention, when the first terminal and the second terminal are unsuccessfully connected, the first terminal ends the operation of communication connection with the second terminal.

And S104, when the communication connection is successful, determining the first data to be transmitted, and sending the first data to be transmitted to the second terminal.

When the communication connection between the first terminal and the second terminal is successful, data transmission between the first terminal and the second terminal can be performed, specifically, the first terminal sends the first to-be-transmitted data list to the second terminal, after the second terminal selects the first to-be-transmitted data list, the selected second to-be-transmitted data list is sent to the first terminal, and the first terminal sends the first to-be-transmitted data corresponding to the second to-be-transmitted data list to the second terminal to complete data transmission between the first terminal and the second terminal.

Further, before the first terminal sends the first data to be transmitted to the second terminal, the first terminal needs to authenticate second identity information of the second terminal, specifically, the first terminal instructs the second terminal to send the second identity authentication information, after the first terminal receives the second identity authentication information, the second identity authentication information is matched with a preset identity information base, and when the second identity authentication information is matched with third identity authentication information in the preset identity characteristic information base, the second identity authentication information corresponding to the second terminal is represented to be successful.

In the embodiment of the invention, the first terminal packs the first data to be transmitted into the data packet and sends the data packet to the second terminal.

Optionally, the first data to be transmitted may include a local application installation package, multimedia data such as voice, picture, video, and the like.

It should be noted that, in the embodiment of the present invention, in the process that the first terminal authenticates the user on the first terminal and the first user on the second terminal, the two users to be authenticated may be the same user or different users, and a specific setting is provided with an actual operation decision, which is not limited in the embodiment of the present invention.

It should be noted that a terminal without faults such as touch screen damage, LCD backlight failure, and the like may also use the method for transmitting data without operating the touch screen of the terminal provided in the embodiment of the present invention, at this time, the terminal may be used as both a receiver and a sender of data to be transmitted, and the specific implementation is implemented according to the requirements of a user, and the embodiment of the present invention is not specifically limited.

It can be understood that the first terminal does not operate the touch screen of the first terminal while performing data transmission with the second terminal, and the first terminal authenticates both the user of the first terminal and the first user of the second terminal before data transmission. Therefore, the safety of data transmission is improved, and the risk of data loss is reduced.

Optionally, the second terminal in the embodiment of the present invention may be a communication device that can perform data transmission, such as a mobile phone and a tablet.

In the embodiment of the present invention, the second terminal starts the communication connection function, and specifically, the communication connection function started by the second terminal should be the same as the communication connection function started by the first terminal.

Optionally, the communication connection function in the embodiment of the present invention may include: WIFI functionality, bluetooth functionality, etc.

Illustratively, the first terminal starts the bluetooth function, and the second terminal needs to start the bluetooth function at this time for the first terminal to search and send a request for communication connection.

S202, when the communication connection with the first terminal is successful according to the communication connection request, the second identity authentication information is authenticated.

The second terminal agrees to perform communication connection with the first terminal, represents that the communication connection between the second terminal and the first terminal is successful, and then needs to perform validity authentication of the identity of the first user.

In the embodiment of the invention, the second terminal receives the communication connection request with the first terminal and is connected with the first terminal, after the communication connection with the first terminal is successful, the first authentication instruction indicating the second identity authentication information by the first terminal is received, the second terminal authenticates the identity of the first user according to the first authentication instruction, specifically, the second terminal acquires the second identity authentication information and sends the second identity authentication information to the first terminal, and the first terminal performs the validity authentication according to the second identity authentication information.
