Description

Technical Field

[0001] The present application relates to the field of input, and in particular to an input method of an encryption keyboard, an input device, a medium and a device of an encryption keyboard. Background Art

[0002] The encryption keyboard has a blank key. For hardware, this key has no special characteristics. The SP layer can enable the blank key by configuring EnableBackSpace. If it is 0, the blank key is not enabled; if it is 1, the blank key is enabled. If the blank key is enabled, the SP layer uses it as a backspace key, which deletes the previous input, and this backspace effect is only valid in GET_DATA; for GET_PIN, that is, when entering a password, the blank key is invalid, and it cannot delete the existing password from the hardware layer. For the "Correct" key of the encryption keyboard, this key has no special characteristics for the hardware device. Due to inconsistent understanding of the correction key by applications, some applications think it is to correct the last key, and some applications think it is to correct all the inputs this time. At the SP layer, the use of the correction key can be configured by ClearToBackspace. When the configuration is 0, it is used as a clear key; when the configuration is 1, it is used as a backspace, and this performance is only valid in GET_DATA. For GET_PIN, this configuration is invalid and can only be used as a clear key. Usually, a keyboard only has one delete key or backspace key, and both keys are not available at the same time, so the delete or backspace functions cannot be used in different application scenarios at the same time. Summary of the invention

[0021] It should be noted that the “at…” in the embodiments of the present application may be the instant when a certain situation occurs, or may be a period of time after the occurrence of a certain situation, and the embodiments of the present application do not specifically limit this.

[0022] The implementation of this embodiment will be described in detail below with reference to the accompanying drawings.

[0023] This embodiment provides an input method for an encryption keyboard. By way of example, the input method for an encryption keyboard can be applied to various electronic devices such as computers (PCs), tablet computers, financial terminals (such as ATMs), virtual reality / augmented reality devices, wearable devices, industrial computers, and car computers; it can also be applied to servers, cloud computing, server clusters, etc., and this embodiment does not make any special limitations on this.

[0024] Figure 1 A flow chart of an input method of an encryption keyboard provided in an embodiment of the present application is shown.

[0025] like Figure 1 As shown, the input method of the encryption keyboard may include the following steps:

[0026] Step 101: Detect the current input scene and the initial key function of the target key, where the key functions of the target key include a delete function and a backspace function.

[0027] Step 102: Detect the character length of the input information, and determine whether to switch the key function of the target key according to the input scenario and the character length.

[0028] Step 103: When the target key is triggered, a corresponding input operation is performed according to the current key function of the target key.

[0029] The encryption keyboard refers to the input tool of the application or terminal, which can be a physical keyboard or a virtual keyboard. The target key is a physical key or a virtual key on the encryption keyboard, which can include a backspace key, a delete key, and a blank key. Usually, there is only one target key on the encryption keyboard. When the target key is used to perform the backspace function, it is called the backspace key. When the target key is used to delete, it is called the delete key.

[0030] In an exemplary embodiment, the input scenario includes a plain text scenario; determining whether to switch the key function of the target key based on the input scenario and the character length includes: when the input scenario is a plain text scenario and the initial key function is a delete function, when the character length is greater than a first preset value, the key function of the target key is switched to a backspace function, and when the character length is not greater than the first preset value, the key function of the target key is maintained as the delete function; when the input scenario is a plain text scenario and the initial key function is a backspace function, when the character length is greater than the first preset value, the key function of the target key is maintained as the backspace function, and when the character length is not greater than the first preset value, the key function of the target key is switched to the delete function.

[0031] In an exemplary embodiment, the input scenario includes a ciphertext scenario; determining whether to switch the key function of the target key based on the input scenario and the character length includes: when the input scenario is a ciphertext scenario and the initial key function is a delete function, when the character length is not less than a second preset value, the key function is switched to a backspace function, and when the character length is less than the second preset value, the key function is maintained as the delete function; when the input scenario is a ciphertext scenario and the initial key function is a backspace function, when the character length is not less than the second preset value, the key function is maintained as the backspace function, and when the character length is less than the second preset value, the key function is switched to the delete function.

[0032] In an exemplary embodiment, the method also includes determining whether the encryption algorithm adopted by the ciphertext scenario is the target algorithm when the input scenario is a ciphertext scenario; if the encryption algorithm is the target algorithm, when the initial key function is a delete function, when the character length is not less than a third preset value, the key function is switched to a backspace function, and when the character length is less than the third preset value, the key function is maintained as the delete function; when the initial key function is the backspace function, when the character length is not less than the third preset value, the key function is maintained as the backspace function, and when the character length is less than the third preset value, the key function is switched to the delete function; the third preset value is greater than the second preset value.

[0033] The first preset value may be 6 characters, the second preset value may be 4 characters, and the third preset value may be 16 characters. It is understandable that the first preset value, the second preset value, and the third preset value may be set according to actual needs, for example, the first preset value is 5, the second preset value is 5, the third preset value is 10, etc., and the present embodiment is not limited thereto.

[0034] This embodiment includes two different business scenarios, one is a plain text scenario, in which the information input by the user can be displayed, the user can see the content he / she input, and the application can also read the content input by the user; the other is a cipher text scenario, in which the application cannot read the content input by the user, and the content input by the user is displayed as cipher text. The following introduces these two scenarios respectively:

[0035] 1) Plain text scenario (such as transfer account input):

[0036] If the target key is initially the Delete key:

[0037] If the entered account number is longer than 6 characters, the delete key will be converted to a backspace key and only 1 character will be deleted.

[0038] If the length of the entered account number is less than or equal to 6 characters, the delete key retains its original function and deletes all characters.

[0039] If the target key is initially the backspace key:

[0040] If the entered account number is longer than 6 characters, the backspace key retains its original function and only deletes 1 character.

[0041] If the length of the entered account number is less than or equal to 6 characters, the backspace key will become the delete key to delete all characters.

[0042] 2) Ciphertext scenarios (such as password input, key input):

[0043] If the target key is initially the Delete key:

[0044] If the entered password is longer than or equal to 4 characters, the delete key turns into a backspace key and only 1 character is deleted.

[0045] If the entered password is less than 4 characters long, the Delete key retains its original function and deletes all characters.

[0046] If the encryption algorithm is 3DES or SM4, when the length of the entered key is greater than or equal to 16 characters, the delete key will be converted to a backspace key, and only one character will be deleted.

[0047] If the entered key is less than 16 characters long, the Delete key retains its original function and deletes all characters.

[0048] If the target key is initially the backspace key:

[0049] If the entered password is longer than or equal to 4 characters, the backspace key retains its original function and only deletes 1 character.

[0050] If the entered password is less than 4 characters long, the backspace key becomes the delete key, deleting all characters.

[0051] If the encryption algorithm is 3DES or SM4, and the key length entered is greater than or equal to 16 characters, the backspace key retains its original function and only deletes one character.

[0052] If the entered key is less than 16 characters long, the backspace key becomes the delete key, deleting all characters.

[0053] In the above implementation, the key function can be dynamically adjusted according to the input length of the input information when the user inputs, so as to adapt to the input scenario of the application and meet the input needs of the user. This implementation can also adjust the key type according to the user's key event. Specifically, it includes: when the initial key function of the target key is to move the cursor left, detecting the user's trigger operation on the target key; if the trigger operation is an operation of clicking twice in a row, the key function of the target key is switched to the cursor left function; if the trigger operation of clicking twice in a row is detected again, the key function of the target key is switched to the backspace function.

[0054] If the key is detected to be pressed twice in quick succession, the key working mode switches to the cursor left shift function. Each time the key is pressed, the cursor moves one position to the left. If it is detected to be pressed twice in quick succession again, the key working mode switches to the backspace key function. If the cursor is in the middle of a character or number, and a number key or character key is detected to be pressed, the number or character is entered at the cursor position, and other numbers or characters to the right of the cursor automatically move to the right. Until the position is full.

[0055] In this implementation, one key switches between delete, backspace, and cursor functions in different scenarios, which can adapt to application services to the greatest extent, improve key utilization, and improve user input efficiency.

[0056] The key function of the target key is adaptively adjusted according to the character length of the input information. When it is detected that the user clicks the target key, the target key is triggered and the corresponding input operation is performed according to the current key function of the target key. If the current key function of the target key is the delete function, the input information that has been entered is deleted; if the current key function of the target key is the backspace function, the last character of the input information that has been entered is deleted.

[0057] The implementation method further includes: displaying prompt information, wherein the prompt information is used to prompt the user of the current key function of the target key. While the key function of the target key is adaptively adjusted, prompt information is displayed to prompt the user of the current key function, so that the user can understand the function of the target key. In addition, switching prompt information can also be displayed, and the switching prompt information is used to prompt the switching condition of the character length.

[0058] The implementation process of the above method is as follows:

[0059] 1) Initialization:

[0060] First, the input buffer is initialized to store the characters entered by the user. Then the key state is initialized to record whether the initial key is the delete function or the backspace function.

[0061] 2)Key event processing

[0062] Capture user key events and determine whether the key type is the delete key or the backspace key.

[0063] Dynamically adjust key functions based on the current input scenario (plain text or cipher text) and input length.

[0064] 3) Plaintext scene processing

[0065] Delete key:

[0066] Check input length:

[0067] If the length is > 6, call the backspace function to delete 1 character.

[0068] If the length is ≤ 6, call the delete key function to delete all characters.

[0069] Backspace key:

[0070] Check input length:

[0071] If the length is > 6, call the backspace function to delete 1 character.

[0072] If the length is ≤ 6, call the delete key function to delete all characters.

[0073] 4) Ciphertext scene processing

[0074] Delete key:

[0075] Check input type (password or key) and length:

[0076] If it is a password and its length is ≥ 4, call the backspace function to delete 1 character.

[0077] If it is a password and its length is < 4, call the delete key function to delete all characters.

[0078] If it is a key and its length is ≥ 16, call the backspace function to delete 1 character.

[0079] If it is a key and its length is <16, call the delete key function to delete all characters.

[0080] Backspace key:

[0081] Check input type (password or key) and length:

[0082] If it is a password and its length is ≥ 4, call the backspace function to delete 1 character.

[0083] If it is a password and its length is < 4, call the delete key function to delete all characters.

[0084] If it is a key and its length is ≥ 16, call the backspace function to delete 1 character.

[0085] If it is a key and its length is <16, call the delete key function to delete all characters.

[0086] In financial terminals (such as ATMs and self-service terminals), users often need to enter sensitive information, such as ID card numbers, bank card numbers, or passbook numbers. In order to improve user experience and input accuracy, terminals usually provide delete or backspace functions to allow users to modify during the input process.

[0087] The present application also provides an adaptive system for key matching deletion or backspace function of a financial terminal, including the following system function modules:

[0088] 1. User input module

[0089] Function: Receive user key input, including numbers, letters, symbols, and special function keys (such as delete key, backspace key, etc.).

[0090] Interaction: Pass the key information entered by the user to the input parsing module for processing.

[0091] 2. Input parsing module

[0092] Function: Parse the key information entered by the user and identify the key type (numbers, letters, symbols, delete key, backspace key, etc.).

[0093] Interaction: Pass the parsed key information to the adaptive matching module for further processing.

[0094] 3. Adaptive matching module

[0095] Functionality: Adaptively match the behavior of the delete or backspace functionality based on the user input history and current input context.

[0096] Interaction: Pass the matching results to the operation execution module to perform corresponding operations.

[0097] 4. Operation execution module

[0098] Function: Execute specific deletion or backspace operations according to the instructions of the adaptive matching module.

[0102] Interaction: Receive feedback from the operation execution module and update the displayed content.

[0103] 6. History Module

[0104] Function: Record the user's input history, including key sequence, operation time, etc., for reference by the adaptive matching module.

[0106] 7. Configuration Management Module

[0107] Function: Manage the configuration parameters of the system, including adaptive matching strategies, user preference settings, etc.

[0108] Interaction: Provide configuration parameters to the adaptive matching module and the operation execution module to ensure the personalization and flexibility of the system.

[0109] Collaborative interaction principles of each module

[0110] 1. User input module → input parsing module

[0111] After receiving the key input from the user, the user input module passes it to the input parsing module for parsing.

[0112] 2. Input parsing module → adaptive matching module

[0113] After the input parsing module parses the key information input by the user, it passes the parsing result to the adaptive matching module for matching processing.

[0114] 3. Adaptive matching module → History module

[0115] The adaptive matching module performs adaptive matching based on the current input and the historical data provided by the history record module.

[0116] 4. Adaptive matching module → operation execution module

[0117] The adaptive matching module passes the matching result to the operation execution module, instructing it to execute the corresponding deletion or backspace operation.

[0118] 5. Operation execution module → user interface module

[0119] After the operation execution module executes the delete or backspace operation, it feeds back the operation result to the user interface module to update the display content.

[0120] 6. Adaptive matching module → configuration management module

[0121] The adaptive matching module adjusts the matching strategy and behavior according to the configuration parameters provided by the configuration management module.

[0122] 1. Input detection: detect each character entered by the user and record the complete string of input.

[0123] 2. Delete / backspace processing: Execute the delete or backspace operation according to the user's selection.

[0124] 3. Input verification: After each modification, re-verify the legality of the input to ensure that the input conforms to the expected format.

[0125] 4. Adaptive prompts: Provide appropriate prompt information based on the current input status to help users complete input.

[0126] For example, suppose a user needs to enter an 18-digit ID number, and the user is allowed to modify it during the input process.

[0161] Furthermore, this embodiment also provides an input device for an encryption keyboard, which can be used to execute the above-mentioned input method for the encryption keyboard. Figure 2 As shown, the input device 200 of the encryption keyboard specifically includes: an information confirmation module 201, which is used to currently detect the current input scene and the initial key function of the target key, and the key function of the target key includes a delete function and a backspace function; an adaptive adjustment module 202, which is used to detect the character length of the input information, and determine whether to switch the key function of the target key according to the input scene and the character length; a function determination module 203, which is used to perform a corresponding input operation according to the current key function of the target key when the target key is triggered.

[0162] In an exemplary embodiment, the input scenario includes a plain text scenario; the adaptive adjustment module 202 is specifically used to, when the input scenario is a plain text scenario and the initial key function is a delete function, switch the key function of the target key to a backspace function when the character length is greater than a first preset value, and keep the key function of the target key as the delete function when the character length is not greater than the first preset value; when the input scenario is a plain text scenario and the initial key function is a backspace function, when the character length is greater than the first preset value, keep the key function of the target key as the backspace function, and switch the key function of the target key to the delete function when the character length is not greater than the first preset value.
