[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The virtual keyboard management method provided in the embodiment of the present application can be applied to the application environment shown in Figure 1. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the input character data of the user that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted device can be a virtual reality (VR) device, an augmented reality (AR) device, smart glasses, etc. The server 104 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0045] The virtual keyboard management method provided in the embodiment of the present application, as shown in the structure of FIG2 , can be applied to most application scenarios of web applications (applications accessed through a browser) that require secure input.

[0046] In one embodiment, as shown in FIG3 , a virtual keyboard management method is provided. This embodiment is illustrated by applying the method to a terminal. It is understandable that the method can also be applied to a server, or to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0047] Step 302, in response to an input operation in the application, based on the user's input habit data or the corresponding security level of the current input environment, determine a corresponding keyboard layout mode.

[0048] In some embodiments, the terminal responds to the user's input operation on the virtual keyboard and customizes the corresponding keyboard layout according to the user's input habits and the security level of the current input environment response.

[0049] Among them, the virtual keyboard is a keyboard displayed on the screen, which the user can operate through a mouse or touch screen; the security level of the current input environment response can be determined by factors such as the current input environment, connected network, and input device.

[0050] Step 304, displaying a virtual keyboard according to the keyboard layout, and obtaining input behavior data generated by the user based on the virtual keyboard, the input behavior data including at least one of keystroke behavior data, modification behavior data, search behavior data, selection behavior data or confirmation behavior data.

[0051] Exemplarily, after the layout of the virtual keyboard is determined, the virtual keyboard is displayed, and at least one of keystroke behavior data of the user on the virtual keyboard is obtained, behavior data is modified, behavior data is searched, behavior data is selected, or behavior data is confirmed.

[0052] Step 306, when the input behavior data does not match the user's input habit data, a security warning is issued externally; when the input behavior data matches the user's input habit data, the characters input by the user are sent to the server.

[0053] In some embodiments, the terminal establishes a normal behavior baseline based on the user's historical input habit data. When it is detected that the user's input behavior deviates from the normal behavior baseline, that is, it does not match the user's input habits, indicating abnormal behavior, a security warning is automatically issued; when the user's input behavior matches the normal behavior baseline, the characters input by the user are sent to the server.

[0054] Among them, the normal behavior baseline is the typical behavior pattern exhibited by an individual or group under normal circumstances in a specific environment; abnormal behavior refers to behavior that does not conform to the user's historical input habits, such as abnormally fast or abnormally slow input speed.

[0055] In another embodiment, the terminal may pre-set a preset risk level. When the risk level of the abnormal behavior is less than the preset risk level, it is ignored; when the risk level of the abnormal behavior is greater than the preset risk level, a security warning is automatically issued.

[0056] In the above virtual keyboard management method, in response to input operations within the application, the corresponding keyboard layout mode is determined based on the user's input habit data or the corresponding security level of the current input environment; according to the keyboard layout mode, the virtual keyboard is displayed, and the input behavior data generated by the user based on the virtual keyboard is obtained, and the input behavior data includes at least one of keystroke behavior data, modification behavior data, search behavior data, selection behavior data or confirmation behavior data; in the case where the input behavior data does not match the user's input habit data, a security warning is issued to the outside; in the case where the input behavior data matches the user's input habit data, the characters input by the user are sent to the server. In this way, by customizing the layout of the keyboard according to different situations and automatically issuing a security warning when an abnormality is identified, the security of the virtual keyboard during use is improved.

[0057] In an exemplary embodiment, the virtual keyboard management method also includes: during the process of the user inputting characters based on the virtual keyboard, when it is detected that the input characters contain sensitive information, initiating multi-factor authentication to the user, and the multi-factor authentication includes at least one of biometric authentication or password authentication.

[0058] In actual implementation, when the user inputs characters based on the virtual keyboard, when the terminal detects that the input characters contain sensitive information, it automatically initiates multi-factor authentication to the user. When the user passes the multi-factor authentication, the characters containing sensitive information entered by the user continue to be uploaded to the server.

[0059] Among them, multi-factor authentication requires users to provide two or more identity authentication factors to access the system, which may be biometric authentication or password authentication, etc., which is not limited in the embodiments of the present application; sensitive information refers to information that may cause harm to personal life, property and safety once it is leaked or used illegally, which may be identity information, payment passwords, etc., which is not limited in the embodiments of the present application.

[0060] In the above embodiment, during the virtual keyboard input process, when sensitive information is involved, multi-factor verification is required to continue uploading the input data, thereby ensuring the security of the input process and preventing information upload errors due to accidental touches.

[0061] In some exemplary embodiments, the process corresponding to the virtual keyboard runs in an isolated sandbox environment.

[0062] Among them, a sandbox environment is an isolated testing environment that allows users to run software, programs or codes in a closed setting without affecting external systems and environments.

[0063] In actual implementation, the entire process of the virtual keyboard running is in an isolated sandbox environment.

[0064] In the above embodiment, by isolating the virtual keyboard and running it in a sandbox environment, it is ensured that even if the web application is attacked, the virtual keyboard will not be invaded.

[0065] In some exemplary embodiments, before displaying the virtual keyboard according to the keyboard layout, the method further includes: obfuscating the logic code of the virtual keyboard and the code injected into the virtual keyboard by the user.

[0066] In actual implementation, before the terminal displays the virtual keyboard according to the customized keyboard layout, it will confuse the logic code of the virtual keyboard and the user-defined code injected into the virtual keyboard. When non-developers enter the debugging interface, they will be stuck in a debugging loop.

[0067] Specifically, the obfuscation process may include replacing some letters, adding meaningless codes, etc. in the logic code of the virtual keyboard without affecting the normal operation of the virtual keyboard.

[0068] In the above embodiment, by performing obfuscation processing in the logic code of the virtual keyboard, the difficulty of cracking the virtual keyboard is increased.

[0069] In some exemplary embodiments, sending the characters input by the user to the server includes: encrypting the characters input by the user by using a digital certificate, and sending the encrypted characters to the server.

[0070] In some embodiments, the terminal uses a digital certificate to encrypt the characters input by the user before sending the characters input by the user to the server.

[0071] The encryption method may be digital certificate encryption, such as TLS / SSL certificate, or other methods with encryption function, which is not limited in the embodiments of the present application.

[0072] In the above embodiment, the security of data during transmission is ensured by encrypting the characters input by the user.

[0073] In some exemplary embodiments, the virtual keyboard management method further includes: in response to a setting operation for the virtual keyboard, setting the key size of the virtual keyboard, and the font and color used when input characters are displayed on the screen.

[0074] In the actual implementation process, the terminal will respond to different users' setting operations for the patrol keyboard, and generate a personalized virtual keyboard layout for each user based on the size of the virtual keyboard set by different users, and the font and color used when input characters are displayed on the screen.

[0075] In the above embodiment, the virtual keyboard layout is different for each user, which increases the difficulty of cracking and improves the security of the virtual keyboard during use.

[0076] To explain the virtual keyboard management method in the present application in detail, an embodiment is used for explanation below. The specific flow chart is shown in FIG4 . By way of example, the present application is explained with a virtual keyboard management method on a specific web application.

[0077] First, before displaying the virtual keyboard according to the customized keyboard layout, the terminal will confuse the logic code of the virtual keyboard and the user-defined code injected into the virtual keyboard.

[0078] Respond to the user's input operation on the virtual keyboard, and customize the size of the corresponding virtual keyboard, the font and color used when the input characters are displayed on the screen according to the user's input habits and the security level of the current input environment response, and generate a personalized keyboard layout.

[0079] A normal behavior baseline is established based on the user's historical input habit data. When it is detected that the user's input behavior deviates from the normal behavior baseline, that is, it does not match the user's input habits, it indicates abnormal behavior, and a security warning is automatically issued; when the user's input behavior matches the normal behavior baseline,

[0080] When the user inputs characters based on the virtual keyboard, it is detected whether the input characters contain sensitive information. If sensitive information is contained, multi-factor authentication is automatically initiated to the user. When the user passes the multi-factor authentication, the characters containing sensitive information input by the user continue to be uploaded to the server.

[0081] Before the characters input by the user are sent to the server, the characters input by the user are encrypted using a digital certificate, and the encrypted characters input by the user are sent to the server.

[0082] This application supports users to set custom encryption methods and layout of keyboard interface keys in a virtual keyboard device, and confuses and anti-debugs user-set logic codes, thereby enhancing the security of the virtual keyboard during use.

[0083] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
