As a bridge connecting users and the online world, browsers have won the favor of the majority of users with their convenient operation interface and powerful functions. However, with the widespread use of browsers, users' privacy protection needs are gradually increasing.

[0016] If the type of the original input box is a plain text input box, adjusting the input content in the plain text input box according to the editing operation, and rendering the adjusted input content in plain text to the plain text input box;

[0017] If the type of the original input box is a ciphertext input box, the input content in the plaintext state is obtained, the input content in the plaintext state is adjusted according to the editing operation, and the adjusted input content is rendered in the ciphertext input box in ciphertext form.

[0018] In one embodiment, the step of adjusting the input content in the plain text input box according to the editing operation includes:

[0019] If the operation type is the insert operation, confirming the type of the insert operation;

[0020] When the type of the insert operation is normal cursor-after-insert, obtaining the position of the system cursor in the input content of the plain text input box, recording it as a first cursor position, inserting the first user content to be inserted at the first cursor position, and recording the input content after the insertion as the first input content;

[0021] When the type of the insert operation is selected insert, the starting position and the ending position of the system cursor in the current input content are obtained and recorded as the first cursor starting position and the first cursor ending position respectively, and the input content between the first cursor starting position and the first cursor ending position is replaced with the second user content to be inserted, and the input content after insertion is recorded as the second input content.

[0041] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0042] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0043] The input box control method of the embodiment of the present application is applied to a browser, and the preset security page of the browser includes an original input box, and the original input box is not configured with a history record function. The original input box includes a plain text input box and a cipher text input box. The input box control method includes: receiving a switching operation of an external input; based on the switching operation, displaying a plain text input box or a cipher text input box, and rendering a corresponding form of input content in the plain text input box or the cipher text input box.

[0044] In this embodiment, for the convenience of description, the following description is made with the browser system as the execution subject.

[0045] Since most current browsers have the function of recording user history, the original intention of this design is to improve the user experience. Through intelligent prediction and automatic backfill functions, it provides convenience when the user searches or enters similar content next time. However, this feature also invisibly lays hidden dangers to the user's privacy and security. When the device is not operated by the user himself, these automatically backfilled personal information, such as search keywords, login credentials and other sensitive data, can easily be inadvertently exposed, thereby causing privacy leakage and security risks to the user.

[0046] The present application provides a solution, which can prevent the leakage of sensitive information by setting a plaintext input box and a ciphertext input box on a preset security page in the browser, and the plaintext input box and the ciphertext input box do not have a history record function. At the same time, the user can flexibly choose between plain text and ciphertext through switching operations, and render the input content in the plaintext input box or the ciphertext input box as needed, thereby enhancing the flexibility of use, meeting different privacy needs, and significantly improving user privacy and data security.

[0047] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a browser system, etc. The following takes the browser system as an example to illustrate this embodiment and the following embodiments.

[0048] Based on this, the embodiment of the present application provides an input box control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the input box control method of the present application.

[0049] In this embodiment, the input box control method is applied to a browser, the preset security page of the browser includes an original input box, the original input box is not configured with a history record function, the original input box includes a plain text input box and a cipher text input box, and the input box control method includes steps S10 to S20:

[0050] Step S10, receiving a switching operation input from an external source;

[0051] It should be noted that the preset security page refers to the page where the browser processes sensitive information, such as the user login page, payment operation page, etc. The original input box does not have functions such as automatic filling and recording history that may leak user privacy, thereby ensuring the immediacy and security of the input content. In the preset security page of the browser, the browser system monitors and receives operation events of the original input box from the user or external device: by clicking the status switching icon next to the original input box that indicates the current input content form, a switching request between the plaintext input box and the ciphertext input box is triggered, including switching the plaintext input box to the ciphertext input box and switching the ciphertext input box to the plaintext input box. These operation events are recorded as switching operations.

[0052] Step S20: Based on the switching operation, a plain text input box or a cipher text input box is displayed, and input content of a corresponding form is rendered in the plain text input box or the cipher text input box.

[0053] It should be noted that the type of state switching icon is determined according to the switching operation of the received external input, including a plaintext icon and a ciphertext icon. The plaintext icon corresponds to switching the plaintext input box to a ciphertext input box, and the ciphertext icon corresponds to switching the ciphertext input box to a plaintext input box. The plaintext input box is used to receive and display input content in plaintext form, and the user can directly view and edit the input content. The ciphertext input box is used to receive and display input content in ciphertext form, and the input content in the input box is encrypted or hidden to prevent sensitive information from being read directly.

[0054] It is understandable that since most current browsers have the function of recording user history records, when the device is not operated by the user himself, the personal information that is automatically filled in can easily be stolen by others, causing the user's personal privacy to be leaked. Therefore, deploying the original input box without the history record function in the browser's preset security page solves the problem of sensitive information leakage that may be caused by the browser's auto-fill function, avoids the risk of malicious exploitation due to security vulnerabilities in the browser or third-party plug-ins, and then leaking user privacy, significantly improves the level of privacy protection when users enter sensitive information, and ensures the security of information during transmission and storage.

[0055] It is understandable that since users need to flexibly switch input box types according to different scenarios to ensure that data input is both convenient and safe, steps S10 to S20 are performed. After receiving the user's switching operation, the browser system dynamically adjusts the type of the original input box according to the specific content of the operation to display input content in different forms, thereby meeting the user's demand for information transparency in different usage scenarios, and ensuring that sensitive information can be protected when it does not need to be directly viewed.

[0056] In a feasible implementation, in step S20, based on the switching operation, the steps of displaying the plain text input box or the cipher text input box and rendering the corresponding form of input content in the plain text input box or the cipher text input box include A01 to A03:

[0057] Step A01, responding to an external switching operation on the original input box, determining the type of the state switching icon before triggering the switching operation, wherein the type of the state switching icon includes a plain text icon and a cipher text icon, which is used to determine the response action of the switching operation;

[0058] It should be noted that the status switching icon refers to the icon next to the original input box that indicates the display status (plain text or cipher text) of the input content in the current original input box. By clicking the status switching icon, the change of the display status of the input content in the current original input box is triggered, including two response actions: switching from cipher text to plain text and from plain text to cipher text. The plain text icon indicates that the display status of the input content in the current original input box is in plain text, which is convenient for users to read and edit directly. The cipher text icon indicates that the display status of the input content in the current original input box is in cipher text, which is used to protect sensitive information from being directly read.

[0059] Step A02, if the type of the state switching icon is a ciphertext icon, the response action of the switching operation is to switch the ciphertext icon to a plaintext icon, hide the ciphertext input box, render the input content in plaintext in the plaintext input box, and display the plaintext input box;

[0060] It should be noted that after the browser system confirms that the type of the current status switch icon is a ciphertext icon, it switches the ciphertext icon to a plaintext icon, visually feedbacks to the user that it has switched to plaintext input mode, hides the current ciphertext input box, and displays the plaintext input box on the browser page. If there is content in the ciphertext input box before hiding, the content in the ciphertext input box before hiding is decrypted and rendered in plaintext in the plaintext input box. If there is no content in the ciphertext input box before hiding, the plaintext input box is kept empty.

[0061] In addition, it should be noted that when the user enters content in the plain text input box, the browser system will enable camera permissions and obtain the current user's surrounding environment image (for example, it can be obtained through the front camera of a mobile phone or computer). The current user's surrounding environment refers to the range of a preset radius (for example, 1 meter) around the user. The acquired current user's surrounding environment image is detected, and the existing people in the current user's surrounding environment image are determined through face recognition. When the number of existing people exceeds 1, the browser system automatically hides the plain text input box and displays the ciphertext input box to make the current plain text input content invisible.

[0062] Step A03, if the type of the status switching icon is a plain text icon, the response action of the switching operation is to switch the plain text icon to a cipher text icon, hide the plain text input box, render the input content in cipher text form in the cipher text input box, and display the cipher text input box.

[0063] It should be noted that, similar to step A02, after confirming that the type of the current status switch icon is a plain text icon, the browser system switches the plain text icon to a cipher text icon, visually feedbacks to the user that the current mode has been switched to cipher text input mode, hides the current plain text input box, and displays the cipher text input box on the browser page. If there is content in the plain text input box before hiding, the content in the plain text input box before hiding is encrypted and rendered in cipher text in the cipher text input box. If there is no content in the plain text input box before hiding, the cipher text input box is kept empty.

[0064] In addition, it should be noted that if the browser system detects that the number of existing people in the user's surrounding environment image exceeds 1, the browser system hides the plaintext input box and displays the ciphertext input box. If the user clicks the status switch icon again within a preset time range (for example, 100 milliseconds to 200 milliseconds), it is determined that the user confirms that the input content is visible, and the browser system hides the ciphertext input box and displays the plaintext input box.

[0065] For example, to help understand the technical concept or technical principle of this application, please refer to Figure 2 , Figure 2A schematic diagram of a scenario for switching between plaintext and ciphertext is provided. In a browser system, initially, the original input box is a ciphertext input box K1. When a user needs to edit or view input content in plaintext form, the user clicks the ciphertext icon M1 next to the ciphertext input box. The ciphertext icon M1 will immediately switch to a plaintext icon M2, and hide the ciphertext input box K1 at the same time. The plaintext input box K2 is displayed to the user, and the input content in plaintext form is rendered in the plaintext input box K2. The user can directly read the content in the plaintext input box. After the user has edited the input content in the plaintext input box K2, if the user wants to hide the input content again, the user can click the plaintext icon M2. The plaintext icon M2 will immediately switch to the ciphertext icon M1, and hide the plaintext input box K2 at the same time. The display of the ciphertext input box K1 is restored, and the input content in ciphertext form is rendered in the ciphertext input box K1.

[0066] In this implementation, by introducing a status switching icon, flexible switching of the input content display status is achieved, which not only meets the user's needs for information visibility in different scenarios, but also ensures that sensitive information is protected when it does not need to be read, protects user privacy from being leaked, simplifies user operations, and improves the usability and security of the system. At the same time, by detecting the number of existing people in the user's surrounding environment image, when other people except the user are detected, it automatically switches to the ciphertext input box, effectively preventing sensitive information from being peeped or stolen by others, thereby improving the security of data input. In addition, the user is allowed to restore the plaintext input box by clicking the status switching icon within a preset time period, taking into account the user's actual need to display the input content, thereby improving the flexibility and convenience of use.

[0067] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 The input box control method further includes: steps S11 to S12:

[0068] Step S11, responding to an external editing operation on the input content in the original input box;

[0069] It should be noted that editing operations refer to any form of modification or adjustment of the input content in the original input box, including but not limited to insertion, deletion, replacement, etc. The browser system captures the user's editing behavior on the original input box through a listener or event handler, such as keyboard input, mouse clicks, etc. These operations are regarded as editing operations on the input content in the original input box.

[0070] Step S12: adjusting the input content in the original input box according to an editing operation, where the editing operation includes at least one of an insert operation and a delete operation.

[0071] It should be noted that the insert operation refers to adding new content or characters to the specified position in the original input box, and the delete operation refers to removing part or all of the input content in the original input box. Once the user's editing operation is captured, the browser system will adjust the content of the input box accordingly according to the specific type of editing operation (insert or delete). For the insert operation, the system will add a new string at the specified position, and for the delete operation, it will remove the string at the selected or specified position.

[0072] In this embodiment, in response to the editing operation of external input, it is ensured that the response speed of the user interface is synchronized with the user's operating intention, the delay is reduced, the user experience is improved, the input content in the original input box is adjusted according to the editing operation, the user's editing instructions are accurately processed, and misoperation or data loss is avoided. The integrity and accuracy of the data are guaranteed, and multiple editing methods are supported at the same time to meet the user's usage needs.

[0073] In a feasible implementation manner, in step S12, the step of adjusting the input content in the input box according to the editing operation includes steps E01 to E03:

[0074] Step E01, determine the type of the original input box;

[0075] It should be noted that determining whether the original input box is a plain text input box or a cipher text input box is the basis for subsequent editing operations.

[0076] Step E02: if the type of the original input box is a plain text input box, the input content in the plain text input box is adjusted according to the editing operation, and the adjusted input content is rendered in plain text to the plain text input box;

[0077] It should be noted that, for the plain text input box, the input content in the plain text input box is directly adjusted, and the adjusted input content is saved.

[0078] Step E03, if the type of the original input box is a ciphertext input box, obtain the input content in the plaintext state, adjust the input content in the plaintext state according to the editing operation, and render the adjusted input content in the ciphertext input box in ciphertext form.

[0079] It should be noted that for the ciphertext input box, since the input content is not directly visible, the input content in the ciphertext input box cannot be directly adjusted. It is necessary to first obtain the input content in the plaintext input box corresponding to the ciphertext input box, and then adjust the input content in the corresponding plaintext input box. For the adjusted input content, determine the string length of the adjusted input content, and render a number of ciphertext symbols equal to the string length in the ciphertext input box.

[0080] In this implementation, by processing the user's editing operations, regardless of whether the input box is a plain text or ciphertext type, the user can obtain immediate and accurate feedback. At the same time, it supports multiple editing operations, so that the system can flexibly respond to different editing needs of users, thereby improving the usability and flexibility of the system. In the ciphertext input box, the user's input content is always displayed in ciphertext form, which effectively prevents the risk of data leakage and greatly improves the security of the system.

[0081] In a feasible implementation manner, in step E02, the step of adjusting the input content in the plain text input box according to the editing operation includes: steps E11 to E13:

[0082] Step E11, if the operation type is an insert operation, confirm the type of the insert operation;

[0083] It should be noted that the insert operation includes normal cursor insertion and selected insertion. By identifying the type of the insert operation that the current user intends to perform, it is ensured that the system can execute corresponding logic according to the type of different insert operations.

[0084] Step E12, when the type of the insert operation is normal cursor insertion, obtaining the position of the system cursor in the input content of the plain text input box, recording it as the first cursor position, inserting the first user content to be inserted at the first cursor position, and recording the input content after the insertion as the first input content;

[0085] It should be noted that the first cursor position refers to the index where the system cursor is currently located in the normal cursor insertion operation, which is used to determine the cursor insertion point position; the first user content to be inserted refers to the text or data that the user wishes to insert at the first cursor position; and the first input content refers to the updated content in the plain text input box after performing the normal cursor insertion operation.

[0086] In addition, it should be noted that when the browser system determines that the type of insert operation is a normal cursor insert, the position of the current system cursor in the input content of the plain text input box is obtained. The system cursor can select only one position or multiple positions at the same time. The first user content to be inserted is inserted at the position selected by the system cursor. When the user makes an input error or wants to re-enter, an undo and redo function is provided to allow the user to cancel an unsatisfactory insert operation or redo the previous operation. When the user completes the input, the display content of the input box is updated, and the inserted content is recorded as the first input content.

[0087] Step E13, when the type of the insert operation is selected insert, obtain the starting position and the ending position of the system cursor in the current input content, record them as the first cursor starting position and the first cursor ending position respectively, replace the input content between the first cursor starting position and the first cursor ending position with the second user content to be inserted, and record the input content after insertion as the second input content.

[0088] It should be noted that the first cursor starting position refers to the starting point index of the plain text input box selected by the user in the select and insert operation, the first cursor ending position refers to the ending point index of the plain text input box selected by the user in the select and insert operation, the second user content to be inserted refers to the new text or data that the user wishes to replace in the selected area, which may be the same as or different from the first user content to be inserted, and the second input content refers to the updated content in the plain text input box after the select and insert operation is performed.

[0089] In addition, it should be noted that when the browser system determines that the type of insert operation is selected insert, the starting position and ending position of the current system cursor in the input content of the plain text input box are obtained. The system cursor can select only the starting position and the ending position, or it can select more than two even positions at the same time. Every two adjacent positions are recorded as a pair of positions to be inserted, and the input content between each pair of positions to be inserted is replaced with the second user content to be inserted. When the user makes an input error or wants to re-enter, an undo and redo function is provided to allow the user to cancel an unsatisfactory insert operation or redo the previous operation. When the user completes the input, the display content of the input box is updated, and the inserted content is recorded as the second input content.

[0090] In this embodiment, by supporting different types of insert operations, users can choose different types of insert operations as needed, thereby improving the flexibility of text editing. At the same time, it supports multi-cursor operations, making complex editing tasks more efficient, and allows users to easily correct errors through the undo / redo function, significantly improving the user's fluency and satisfaction during the editing process.

[0091] In a feasible implementation manner, in step E02, the step of adjusting the input content in the plain text input box according to the editing operation includes: steps E21 to E23:

[0092] Step E21, if the operation type is a delete operation, confirm the type of the delete operation;

[0093] It should be noted that the delete operation includes normal cursor delete and selected delete. By identifying the type of delete operation that the current user intends to perform, it is ensured that the system can execute corresponding logic according to the type of different delete operations.

[0094] Step E22, when the type of the deletion operation is normal cursor-back deletion, the position of the system cursor in the current input content is obtained, recorded as the second cursor position, and the content to be deleted by the user is deleted from the second cursor position forward, and the input content after deletion is recorded as the third input content;

[0095] It should be noted that the second cursor position refers to the index where the system cursor is currently located in the normal cursor delete operation, which is used to determine the cursor deletion point position; the user content to be deleted refers to the text or data that the user wants to delete; the third input content refers to the updated input content in the plain text input box after the normal cursor delete operation is performed.

[0096] In addition, it should be noted that when the browser system determines that the type of deletion operation is normal cursor deletion, the position of the current system cursor in the input content of the plain text input box is obtained. The system cursor can select only one position or multiple positions at the same time, and the user's content to be deleted is deleted from the position selected by the system cursor. When the user deletes incorrectly or wants to delete again, an undo and redo function is provided to allow the user to cancel an unsatisfactory deletion operation or redo the previous operation. When the user completes the deletion, the display content of the input box is updated, and the deleted content is recorded as the third input content.

[0097] Step E23, when the type of deletion operation is selected deletion, obtain the starting position and the ending position of the cursor in the current input content, record them as the second cursor starting position and the second cursor ending position respectively, delete the input content between the second cursor starting position and the second cursor ending position, and record the deleted input content as the fourth input content.

[0098] It should be noted that the second cursor starting position and the second cursor ending position respectively indicate the starting and ending positions of the input content that the user wishes to delete in the plain text input box in the select and delete operation, and the fourth input content refers to the updated input content in the plain text input box after the select and delete operation is performed.

[0099] In addition, it should be noted that when the browser system determines that the type of deletion operation is selected deletion, the starting position and ending position of the current system cursor in the input content of the plain text input box are obtained. The system cursor can select only the starting position and the ending position, or it can select more than two even positions at the same time. Every two adjacent positions are recorded as a pair of positions to be deleted, and the input content between each position to be deleted is deleted. When the user deletes incorrectly or wants to delete again, an undo and redo function is provided to allow the user to cancel an unsatisfactory deletion operation or redo the previous operation. When the user completes the deletion, the display content of the input box is updated, and the inserted content is recorded as the fourth input content.
