Description

Input method and terminal device

Technical field

The embodiments of the present application relate to the field of information technology, and more specifically, to an input method and a terminal device.

Background technique

With the development of technology and the demand for information security, more and more terminal devices are provided with fingerprint collection devices. The user can pre-enter one or more fingerprint information through the fingerprint collection device. The terminal device can generate a corresponding fingerprint template according to the fingerprint information that is pre-recorded. In some application scenarios, for example, unlocking the terminal device, starting an application in the terminal device, and the like, the fingerprint may be used to verify the legal identity of the user.

However, once the legal identity verification is completed, anyone can operate the terminal device. For example, when the terminal device is in the unlocked state, anyone can operate the terminal device, for example, view information such as pictures, video files, short messages, and call records saved by the terminal device. This may result in the leakage of privacy of the user. For another example, after the user logs in and unlocks the app, anyone can perform normal operations on the app, such as viewing content saved in the app. This will also cause leakage of the user's privacy. In addition, if the application that the user logs in and unlocks is an application related to financial property, the user's property may also be lost. For example, if the application is a bank client, anyone can view account balances, transaction records, etc. after the user logs in and unlocks the application. If you know the transaction password of the user, you can transfer the funds in the user account to other accounts without authorization.

Therefore, how to improve the security of an application running in a terminal device or a terminal device after unlocking is an urgent problem to be solved.

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

The touch recognition area of the terminal device in the present application includes a fingerprint collection area used by the terminal device to collect fingerprints. The terminal device may be a mobile phone, a tablet computer, a computer, etc., and the application is implemented. This example is not limited to this.

The manner in which the terminal device implements touch recognition in the touch recognition area in the embodiment of the present application includes, but is not limited to, a capacitive touch sensor and an inductive touch sensor.

The manner in which the terminal device implements fingerprint collection in the fingerprint collection area in the embodiment of the present application includes, but is not limited to, a push type fingerprint recognition device and an optical fingerprint recognition device.

The location of the fingerprint collection area in the embodiment of the present application may be located on the front, the back, or the side of the terminal device, or may be located in the display area of the terminal device.

FIG. 1 is a schematic flowchart of an input method according to an embodiment of the present application. The method shown in Figure 1 can be performed by a terminal device.

101. Determine the validity of the input acquired in the touch recognition area of the terminal device when the terminal device is in the unlocked state, where determining, by the terminal device, the validity of the input acquired in the touch recognition area is: When the input fingerprint information is collected, it is determined whether a matching fingerprint template is saved in the fingerprint database, and if the matching fingerprint template is saved in the fingerprint database, it is determined that the input is a valid input, and if the matching fingerprint is not saved in the fingerprint database The template or the fingerprint information of the input is not collected, and the input is determined to be an invalid input, wherein the matching fingerprint template is a fingerprint template matching the input fingerprint information.

102. Determine input information of the input, wherein the input information of the input includes a duration of the input and location change information of the input.

103. In case the input is a valid input, an operation event is determined according to the input input information.

104. In the case where the input is a valid input, the operation event is performed, wherein the validity of the acquired input is determined each time an input is acquired in the touch recognition area of the terminal device.

According to the method shown in FIG. 1, in the case where the terminal device is in the unlocked state, each time the user inputs the touch recognition area, it is necessary to determine whether the user who performs the input is a legitimate user. Thus, even if the terminal device is in the unlocked state, the non-legitimate user cannot operate the end device through a touch operation. In this way, the security of the terminal device can be greatly improved.

Optionally, in some embodiments, before determining the validity of the input obtained by the touch identification area of the terminal device, the method may further include: determining that the terminal device is running the specified application, wherein the specified application It is a pre-set application. The preset may be preset by the user or may be preset by the operating system of the terminal device. The above technical solution can specify one One or more applications, each time the input is detected in the touch recognition area, it is necessary to verify whether the user who generated the input is a legitimate user. Other applications (ie, applications that do not belong to the specified one or more applications) do not need to verify that the input detected by the touch area is entered by a legitimate user each time during the run. In this way, anyone can use the terminal device to run the other application. The above technical solution not only satisfies the convenience of using the terminal device, but also achieves the purpose of protecting user privacy and property security.

For example, the specified one or more applications may be applications that involve personal privacy, such as photos, text messages, applications related to financial assets (eg, bank clients), and the like. The other application may be an application that does not involve personal privacy, such as games, information applications, and the like. In this way, in the case where the terminal device is in the unlocked state, anyone can use the terminal device to run a non-designated application such as a game or an information application. However, only legitimate users can use photos, text messages, etc. to specify applications.

Optionally, in some embodiments, before determining the validity of the input acquired by the touch recognition area, the method may further include: determining that the terminal device is running a specified function module of the application, wherein the designated function module A function module preset for the user or a function module that needs to verify that the user is a legitimate user. Based on the above technical solution, anyone can use the non-designated function module of the application normally, but only the legal user can use the specified function module. The above technical solution not only satisfies the convenience of using the terminal device, but also achieves the purpose of protecting user privacy and property security.

An application may include different functional modules. For example, the phone application can include a call recording function module, a contact function module, and a dial keypad function module. Based on the technical solution provided by the embodiment of the present application, the user of the terminal device may preset the call record module and the contact function module as the designated function module. In this way, anyone can make a call using the dial pad function module of the phone application of the terminal device, but the call record and the contact information cannot be viewed. When the user sets the specified function module, the user needs to verify that the user is a legitimate user. Authentication methods include, but are not limited to, fingerprint verification, password verification, and voiceprint verification.

As another example, the camera application can include a camera function module, a camera function module, and an album function module. The user of the terminal device can preset the album function module as the designated function module. In this way, anyone can take photos with the camera function module or use the camera function module to take pictures, but cannot view photos saved in the album. Similarly, when setting the specified function module, the user needs to verify that the user is a legitimate user. Authentication methods include, but are not limited to, fingerprint verification, password verification, and voiceprint verification.

As another example, bank client applications typically include functional modules related to financial assets, such as transfers, transaction record inquiries, and purchase of wealth management products. Bank client applications usually include some information function modules, such as financial product recommendation, financial information, and so on. Users need to authenticate when using functional modules related to financial assets. The functional module related to the financial property can only be run if the user is a legitimate user. Authentication methods include, but are not limited to, fingerprint verification, password verification, and voiceprint verification. The functional module related to the financial property is the designated functional module. Based on the technical solution provided by the embodiment of the present application, although the terminal device is running the specified function module, it is required to verify whether the user who generated the input is a legitimate user each time the input is detected in the touch recognition area. In this way, anyone can use the information function module of the bank client application, but can not perform operations related to financial assets such as transfer, transaction record inquiry.

Optionally, in some embodiments, the determining the input information of the input comprises: acquiring a start time of the input and an end time of the input; determining, according to the start time of the input and the end time of the input, The duration of the input; the start position of the input and the end position of the input; and the position change information of the input is determined according to the start position of the input and the end position of the input.

Specifically, as long as the touch object (for example, a finger or a stylus) starts to contact the touch recognition area, the input is sequentially started, and the touch object is separated from the touch recognition area to indicate that the input ends. For example, a double-click operation is an operational event that results from two inputs. This is because when the user completes a click, they need to raise their finger and then click on the same location again. For another example, if the touch state is moved back to the touch recognition area after moving from the touch recognition area to the non-touch recognition area (for example, the border of the terminal device) during the continuous movement of the finger, the input is also two times.

Optionally, in some embodiments, determining the operation event according to the input information of the input includes: determining, according to the duration of the input and the position change information of the input, the operation event as a click operation or a long press operation Or determining the operation event as a sliding operation according to the input position change information.

For example, in a case where it is determined that the position change information of the input does not change and the duration of the input is less than the first preset time range, it is determined that the operation event is a click operation.

For another example, in a case where it is determined that the position change information of the input does not change and the duration of the input is greater than the first preset time range, it is determined that the operation event is a long press operation.

For another example, in a case where it is determined that the position change information of the input changes, the first operation time is determined to be a slide operation. Further, according to the input position change information and the input The duration determines the sliding speed of the sliding operation.

2 is a schematic diagram of a terminal device in an unlocked state. The terminal device 200 shown in FIG. 2 includes a display screen 201 and a button 202. The touch recognition area of the terminal device 200 includes an area where the display screen 201 is located and an area where the button 202 is located. The fingerprint identification area of the terminal device 200 is located in the area where the button 202 is located. FIG. 2 is a schematic diagram of the terminal device 200 in an unlocked state. As shown in FIG. 2, when the terminal device 200 is in the unlocked state, the display interface of the display screen 201 presents a total of 16 icons in 4 rows and 4 columns. The icon indicated by the first dotted line of the first line of the display interface 201 of the terminal device 200 shown in FIG. 2 is the default candidate icon.

The registered finger referred to in the following embodiment means that the terminal device 200 holds a fingerprint template corresponding to the registered finger. In other words, the terminal device 200 can confirm that the input generated by the registered finger is a valid input. The unregistered finger referred to in the following embodiment means that the terminal device 200 does not store a fingerprint template corresponding to the unregistered finger. In other words, the terminal device 200 can determine that the input generated by the unregistered finger is an invalid input.

When the terminal device 200 is in the unlocked state, it is necessary to judge the validity of the acquired input each time the input is acquired in the touch recognition area. Taking FIG. 2 as an example, whether the user is a legitimate user or not, the input of the icon selected by the user directly on the display screen 201 using the finger is an invalid input. This is because the input fingerprint is not acquired in the area where the display 201 is located, and thus the input fingerprint information generated by the finger cannot be detected. Inputs that cannot detect fingerprint information are invalid inputs.

The user can operate the terminal 200 in the fingerprint identification area. For example, the user can click on the fingerprint identification area using the registered finger (ie, touch an area within the range of the fingerprint identification area (ie, the area where the button 202 is located) and quickly lift up, the input is not in the fingerprint identification area. Move and the duration of this input is very short). In this case, the input can be considered a click operation. Since the input is made by the user using the registered finger, it can be determined that the input is a valid input. In this case, the terminal device 200 can perform a one-click operation. The result of the operation of the terminal device 200 performing the click operation may be to start an application corresponding to the candidate icon. If the user clicks on the fingerprint identification area using an unregistered finger, it can be determined that the input is an invalid input. In this case, the terminal device 200 does not perform a click operation.

For another example, the user performs a rightward sliding input on the fingerprint recognition area using the registered finger, and the terminal device 200 can determine that the operation event generated by the input is a rightward sliding operation. Since the input is made by the user using the registered finger, it can be determined that the input is a valid input. In. In this case, the terminal device 200 can perform a rightward sliding operation. As a result of the terminal device 200 performing the rightward sliding operation, the candidate icon can be changed from the icon of the first line of the first line as shown in FIG. 2 to the other icon. Similarly, if the user is using an unregistered finger to make a right swipe input on the fingerprint recognition area, it can be determined that the input is an invalid input. In this case, the terminal device 200 does not perform a sliding operation to the right.

Optionally, in some embodiments, the terminal device 200 may determine the changed candidate icon according to the sliding distance of the sliding operation. For example, if the sliding distance is less than the first distance threshold, the changed candidate icon is the second icon of the first line. For another example, if the sliding distance is greater than the first distance threshold and less than the second distance threshold, the changed candidate icon is the third icon of the first line.

Optionally, in other embodiments, the terminal device 200 may determine the changed candidate icon according to the sliding speed of the sliding operation.

Optionally, in other embodiments, the terminal device 200 may determine a better candidate icon according to the sliding speed and the sliding distance of the sliding operation.

Similarly, in addition to selecting a candidate icon by swiping to the right, the user can also use the registered finger to slide the selection candidate icon in other directions. The specific implementation is similar to the manner of sliding the selection candidate icon by swiping to the right, and need not be described here.

As another example, the user can use the registered finger to long press the fingerprint identification area (ie, an area of the fingerprint identification area is known and stays for a period of time, and the input does not move within the fingerprint identification area). In this case, the input can be considered to be a long press operation. Since the input is made by the user using the registered finger, it can be determined that the input is a valid input. In this case, the terminal device 200 can perform a long press operation. The result of the terminal device 200 performing the long press operation may be that the preset content is presented on the display screen 201 of the terminal device 200. Similarly, if the user uses an unregistered finger to press the fingerprint recognition area, it can be determined that the input is an invalid input. In this case, the terminal device 200 does not perform a long press operation.

Further, the terminal device 200 can determine a corresponding operation according to an operation event that the user continuously inputs a plurality of times. For example, the terminal device 200 detects that the user clicks the fingerprint recognition area using the registered finger for two consecutive times within a certain time range, and the terminal device 200 can perform a double-click operation. However, if the user clicks the fingerprint recognition area once each time using the registered finger and the unregistered finger in the time range, the terminal device 200 cannot perform the double-click operation.

In the above embodiment, the user can select an application that is desired to run in the terminal device 200 through the fingerprint identification area. Similarly, if the terminal device 200 is running the specified application or the designation of the application Function module, the user can also select the content in the application that he wants to open through the fingerprint identification area. For example, the user can use the registered finger to perform a sliding input in the fingerprint recognition area to select a candidate content that is desired to be opened, and then use the registered finger to click the fingerprint identification area to open the selected candidate content.

3 is a schematic diagram of another terminal device in an unlocked state. The terminal device 300 shown in FIG. 3 includes a display screen 301. The touch recognition area of the terminal device 300 includes an area where the display screen 301 is located. The fingerprint identification area of the terminal device 300 also includes the area where the display screen 301 is located. That is to say, the area where the display screen 301 is located can acquire input input information as well as input fingerprint information.

In this case, the terminal device 300 performs only an operation event generated by the user using the input of the registered finger in the area where the display screen 301 is located. If the input is made by the unregistered finger on the display screen 301, the terminal device 300 does not perform the operation event corresponding to the input. That is, the user can normally operate the terminal device 300 using the registered finger, such as clicking an icon presented on the display screen 301, dragging the icon, and switching the displayed icon by sliding. However, even if the terminal device 300 is already in the unlocked state, the unregistered finger cannot operate the terminal device 300, or can only operate the limited application or the function module in the application set by the legitimate user or the terminal device.

And determining whether the matching fingerprint template is saved in the fingerprint database, and determining that the input is a valid input when the matching fingerprint template is saved in the fingerprint database, and the matching fingerprint template is not saved in the fingerprint database or the fingerprint identification unit 403 is not collected. The input is determined to be an invalid input in the case of the input fingerprint information, wherein the matching fingerprint template is a fingerprint template that matches the input fingerprint information.

The touch recognition unit 402 is configured to determine input information of the input, wherein the input input information includes a duration of the input and position change information of the input.

The processing unit 401 is further configured to determine an operation event according to the input input information, and execute the operation event if the input is a valid input, where the processing unit 401 is in the touch recognition area each time the touch recognition unit 402 is located In the case where the input is obtained, the validity of the input acquired by the touch recognition unit 402 is judged.

In the case where the terminal device 400 is in the unlocked state, each time the user inputs the touch recognition area, it is necessary to determine whether the user who performed the input is a legitimate user. Thus, even if the terminal device 400 is in the unlocked state, the non-legitimate user cannot operate the end device by a touch operation. In this way, the security of the terminal device 400 can be greatly improved.

Optionally, in some embodiments, the processing unit 401 is further configured to determine that the terminal device is running a specified application, where the specified application is a preset application.

Optionally, in some embodiments, the processing unit 401 is further configured to determine that the terminal device is running a specified function module of the application, where the designated function module is a function module preset by the user or needs to verify that the user is a legitimate user.
