Description

Character input method and device in mobile terminal

technical field

The embodiment of the present invention relates to mobile communication technology, and in particular to a character input method and device in a mobile terminal.

Background technique

With the continuous development of terminal technology and wireless services, more and more terminal users conduct wireless services through various mobile terminals (for example, smart phones or tablet computers, etc.). For example, financial services such as shopping, transfers, and payment of utility bills.

Generally speaking, when a terminal user conducts a financial service business transaction through a mobile terminal, in order to ensure the reliability and legitimacy of the transaction, the user is usually required to enter a valid user name and password to ensure the normal progress of the transaction. Most of the existing mobile terminal password input methods are that after the user opens the password input window, he clicks or touches the physical button or virtual button of the mobile terminal to input the corresponding letters or numbers. After the user completes the input, he clicks the confirmation button to submit the password. Afterwards, the trading system verifies the legitimacy of the user's password through a dedicated password verification server. Among them, in order to reduce the risk of the password being leaked, the password currently entered by the user will be displayed as a specific symbol in the password input box, for example, an asterisk or a dot.

However, when a user needs to enter a password using a mobile terminal in a densely populated public place, such as a subway or a shopping mall, the password being entered may be peeped by other people or photographed by a monitoring device, which will cause serious problems for the user. unnecessary economic loss.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.

first embodiment

Fig. 1 is a flowchart of a character input method in a mobile terminal according to the first embodiment of the present invention, the method of this embodiment can be executed by a character input device in the mobile terminal, and the device can be implemented through hardware and/or software Generally, it can be used in conjunction with the input method program integrated in the mobile terminal, or as a subroutine of the input method program. In a specific example, in the process of completing a financial transaction through a mobile terminal, the user needs to enter a transaction password (for example, Alipay password or bank card password, etc.) through the mobile terminal. The character input device can be used to complete the password input, or the character input device downloaded on the financial transaction platform can be used as an input plug-in to complete the password input, which is not limited.

Correspondingly, the method in this embodiment specifically includes the following steps:

Step 110: Determine actual input characters according to the received original input characters and auxiliary input instructions.

In this embodiment, the mobile terminal determines actual input characters according to the received original input characters and auxiliary input instructions.

Wherein, the original input characters include at least two input characters, and the actual input characters include at least one input character.

In this embodiment, the original input characters specifically include: the characters input by the user to the mobile terminal by clicking a physical button or touching a virtual button; and the actual input characters specifically include: the characters included in the original input characters according to the actual input sequence. The character actually expected to be entered.

For example: the original input character entered by the user is "12340508", but the actual input character expected by the user is "2008" contained in "12340508" according to the actual input sequence.

In this embodiment, the mobile terminal determines which original input characters are actual input characters through auxiliary input instructions.

Among them, the auxiliary input instruction may specifically include: the user touches or long presses a special button (for example, volume up key or volume down key, etc.) (For example, the area where the photosensitive element of the mobile terminal is located or the touch area on the back of the mobile terminal, etc.) triggers the generated instructions, etc., which is not limited.

In a preferred implementation of this embodiment, the mobile terminal can determine the actual input character according to the detected combination of the auxiliary input instruction and the current input character.

For example, during the process of receiving the original input character "12340508" input by the user, when the mobile terminal receives the auxiliary input instruction within a predetermined time (for example, 1s) after receiving the input character "2", it will input Character "2", as an actual input character.

Step 120, sending the actual input characters to the character verification platform.

In this embodiment, the mobile terminal sends the actual input characters to the character verification platform.

Wherein, the character input platform may specifically include a platform for verifying the consistency of the characters actually input by the user. For example: if the mobile terminal receives the QQ password input by the user, the character verification platform is specifically the QQ password verification platform; if the mobile terminal receives the Alipay password input by the user, the character verification platform is specifically the Alipay password verification platform.

The embodiments of the present invention determine the actual input characters according to the received original input characters and auxiliary input instructions; the technical means of sending the actual input characters to the character verification platform solves the problem of the existing password input technology when the user needs less personnel. When entering a password in a dense public place, the password being entered may be leaked due to other people peeping or being photographed by a monitoring device, which improves the reliability and security of the password input technology and optimizes the existing mobile terminal-based The password input technology satisfies people's increasing demand for personalized and convenient password input.

In another preferred implementation of this embodiment, the determination principle for the mobile terminal to determine whether a combination of an auxiliary input instruction and the currently input character is detected may be as follows:

The mobile terminal determines whether the auxiliary input instruction is received within a second predetermined time threshold after receiving the currently input character, and if so, takes the currently received input character as the actual input character.

In another preferred implementation of this embodiment, the above two judging principles for judging whether a combination of an auxiliary input instruction and a currently input character is detected may also be used simultaneously, and there is no limitation thereto.

Wherein, the setting of special symbols may specifically include: asterisk, pound sign, or dot, etc., which is not limited.

In this embodiment, the front-end application specifically includes a human-computer interaction interface provided by the application program to the user through the mobile terminal for completing character input.

For example, when a user logs into the QQ software through a mobile terminal, the front-end application of the QQ software provides the user with a user name and password input box through the mobile terminal to instruct the user to complete the character input of the corresponding user name and password. When the user inputs a character in the password input box, the input character is displayed in the password input box in the form of setting a special symbol ("*" or "#", etc.).

Step 250 , judging whether the original input character has been inputted: if yes, execute step 260 ; otherwise, return to step 210 .

Step 260, use the input character stored in the actual input buffer list as the actual input character, and execute step 270.
