[0045] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] The terms "first", "second", and "third" and the like in the present application are used to distinguish different objects, rather than to describe a specific sequence. At the same time, the term "comprise" and any form of variation thereof is intended to cover non-exclusive inclusion.

[0047] The embodiments of the present application provide a secure keyboard input method, device, equipment and storage medium. According to the embodiments of the secure keyboard input method provided by the embodiments of the present application, it should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the described or shown steps can be executed in a different order from here.

[0048] In some embodiments of the present application, the secure keyboard input method can be applied to at least one of a computer device and a terminal device, wherein the computer device can be a stand-alone server, or a server network or a server cluster composed of servers, such as a computer, a network host, a single network server, a plurality of network server sets, or a cloud server composed of a plurality of servers. The cloud server is composed of a large number of computers or network servers based on cloud computing. The terminal device includes, but is not limited to, a smart phone, a tablet computer, and a PC terminal. In some embodiments of the present application, when the secure keyboard input method is applied to the computer device and the terminal device, the terminal device and the computer device can communicate through any communication method, wherein the communication method includes, but is not limited to, mobile communication based on the 3rd Generation Partnership Project (3GPP), Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX), or computer network communication based on the TCP / IP Protocol Suite (TCP / IP), User Datagram Protocol (UDP), and the like.

[0049] Referring to Figure 1 For example, the electronic device integrated with the secure keyboard input device can obtain an initial keyboard, wherein the initial keyboard is generated on a first interface of the cloud mobile terminal; in response to a first operation of a user on the initial keyboard, a first input instruction is sent to the client; according to the first input instruction, the client generates a secure keyboard on a second interface; in response to a second operation of the user on the secure keyboard, the client generates input information; and the input information is received to complete the input operation on the cloud mobile terminal.

[0050] In some embodiments of the present application, the secure keyboard input method can be applied to scenarios such as user password input and cloud mobile application use. As shown in Figure 2 and Figure 3 As shown in Figure 2 is an embodiment flow diagram of the secure keyboard input method provided by the embodiments of the present application, and the secure keyboard input method includes steps 201-205.

[0051] Step 201, obtaining an initial keyboard.

[0052] The initial keyboard can be generated on a first interface of a cloud phone. The cloud phone is a mobile phone using cloud computing technology in network terminal service and achieving cloud service through a cloud server. The first interface is a display and operation interface of the cloud phone.

[0053] It can be understood that in the scenario where the user uses the cloud phone application, the user may be involved in operations such as inputting a password, personal information, and transmitting a file. The cloud phone can be used by multiple different users, and the operation environment corresponding to different users can be different, so that the user may face the situation of information theft or leakage when performing the above operations on the initial keyboard generated by the user on the first interface of the cloud phone.

[0054] In step 202, a first input instruction is sent to the client in response to a first operation of the user on the initial keyboard.

[0055] Optionally, step 202 can further include:

[0056] detecting whether the first operation meets a preset condition;

[0057] if the preset condition is met, the first input instruction is sent to the client in a first mode;

[0058] if the preset condition is not met, the first input instruction is not generated.

[0059] The preset condition can include that the first operation meets a password input behavior. The password input behavior can include a first behavior for representing a suspected password input behavior and a second behavior for representing a correct password input behavior.

[0060] In some scenarios, when the user continuously inputs letters, numbers, special symbols, or a combination of the above in the initial keyboard, it can be detected that the user triggers the first behavior, and the preset condition is met. Accordingly, the server can detect that the user inputs part of the characters of the correct password in the initial keyboard, and then detect that the user triggers the second behavior. For example, the correct password is "123456789", and if it is detected that the user inputs "123" in the initial keyboard, it is determined that the target inputs the first three characters of the correct password, and it is determined that the user triggers the second behavior. It should be noted that the number of characters required by the user to trigger the second behavior is not limited in this embodiment.

[0061] The first mode can be transmission through a websocket protocol to further enhance security and privacy.

[0062] Therefore, based on the above behaviors, the user can input the password or other important information incompletely on the cloud mobile terminal, and then jump to the client through the operation of triggering the preset condition, so as to significantly improve the security and privacy of information input.

[0063] Step 203, according to the first input instruction, the client generates a secure keyboard on the second interface.

[0064] According to the description of step 202, after the user performs the first operation that meets the preset condition, in order to ensure security and privacy, the subsequent input information operation can be transferred to the client for continuous operation, so that the subsequent input operation can be performed on any keyboard with information input function on the client. For example, a new secure keyboard can be generated on the second interface of the client, or a secure keyboard installed on the client can be called.

[0065] Step 204, in response to the second operation of the user on the secure keyboard, the client generates input information.

[0066] Optionally, step 204 can further include the following steps:

[0067] Detect whether the second operation includes a password input completion operation or a password input confirmation operation;

[0068] If yes, continue to generate the input information;

[0069] If no, do not generate the input information.

[0070] The input completion operation refers to the operation of the user completing the input information. In some embodiments, the no-operation duration when the user enters a no-operation state after inputting information can be detected. If the no-operation duration is greater than a preset threshold, for example, the preset threshold can be 5 seconds, 10 seconds, 1 minute, etc., it means that the user has completed the operation of inputting information with high probability, and the client confirms to generate the input information input by the user. In other embodiments, the client can detect that the user has input the correct password, information, which means that the user has correctly and completely input the corresponding password, and the second operation is identified as the input completion operation.

[0071] In some embodiments, the user can also be detected by detecting the password input confirmation behavior to identify whether the user has completed the operation of inputting information. For example, after the user completes the input of information, the client can detect the user by clicking the confirmation, completion, login, sending and other function controls.

[0072] Step 205, receive the input information to complete the input operation on the cloud mobile terminal.

[0073] Specifically, the client can transmit input information to the cloud phone via the WebSocket protocol, enabling the input information to be used by the cloud phone application in a secure transmission environment.

[0074] Optionally, embodiments of this application may further include the following steps:

[0075] Based on the input information, generate a first hash value and a first code;

[0076] Based on the correct password corresponding to the input information, generate the encryption code and the corresponding decryption code;

[0077] If the first encoding matches the decryption encoding, a second hash value is generated, and it is determined whether the second hash value is consistent with the first hash value.

[0078] If the second hash value matches the first hash value, the cloud mobile terminal decrypts the input information.

[0079] Specifically, after encrypting and storing the input information in memory, a first hash value can be generated. This first hash value is used to verify whether it matches the second hash value generated when decrypting the input information, thereby determining whether there has been a memory tampering operation.

[0080] As can be seen from the above, this application embodiment detects the user's password input behavior on the cloud mobile terminal and generates a secure keyboard on the user's client. This allows the user to input information on the secure keyboard in a client environment with strong privacy and security, and then transmit the input information to the cloud mobile terminal via network protocol. This greatly improves the privacy and security of the user's information input and acquisition on the cloud mobile terminal.

[0081] To better implement the secure keyboard input method provided in the embodiments of the present invention, a secure keyboard input device is provided based on the secure keyboard input method, such as...
