detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, during the call, after the calling user hears the prompt tone for entering the password, he first selects the password protection item corresponding to the password type, reads the password stored in the password protection item, and The last bit of the password is added with a password terminator to generate a password bit; then the password bit is processed to generate a DTMF signal corresponding to the password bit, and to shield the generation of a key tone corresponding to the DTMF signal.

The realization of the present invention is described in detail below in conjunction with specific embodiment:

Embodiment one

Fig. 1 shows the implementation flowchart of the password input method provided by Embodiment 1 of the present invention. For the convenience of explanation, only the parts related to the embodiment of the present invention are shown, and the details are as follows:

In step S101, during a call, a signal prompting password input sent by the called user terminal is received and played to the calling user.

In the embodiment of the present invention, during the conversation between the calling user and the called user, the calling user hears a voice signal prompting to input a password. Wherein, the voice signal prompting to input the password is sent from the called user terminal to the mobile terminal used by the calling user, and played by the mobile terminal to the calling user.

In step S102, the selected password protection item is received, and the password protection item is in one-to-one correspondence with the type of password to be input.

In the embodiment of the present invention, according to the different services handled by the calling user, the calling user will hear the input of different types of passwords. When the customer service calls, you may be asked to enter the service password. In a word, the types of passwords prompted to be input will be different for different services handled by the calling user. Therefore, the calling user first needs to set different types of passwords in the mobile terminal according to the type of business to be handled, and save these different types of passwords to preset password protection items or newly created password protection items, wherein , one type of password is stored in a password-protected item. Moreover, after the password is saved, the password protection item corresponding to the password can only be deleted, and cannot be viewed or modified.

After the user hears the voice signal played by the mobile terminal prompting to enter the password, in the call settings, select and click the password protection item that stores this type of password. The type of password stored in the password protection item is the same as that heard by the user. The type of password that needs to be entered is the same.

In step S103, the password stored in the password protection item is read, and a password terminator is added to the last digit of the password to generate password digits.

In the embodiment of the present invention, after the mobile terminal used by the calling user receives the password protection item selected by the user, it reads the password stored in the password protection item, and adds the password terminator "#" at the end of the password number to generate a password bit, which is equivalent to the calling user entering a string of password bits through the keyboard of the mobile terminal.

In step S104, the password bits are processed, a DTMF signal corresponding to the password bits is generated, and generation of a key tone corresponding to the DTMF signal is shielded.

In the embodiment of the present invention, after step S103 is used to generate the password digits equivalent to input through the keyboard of the mobile terminal, the mobile terminal used by the calling user invokes a corresponding processing function to process the password digits to generate a password corresponding to the password digits. The corresponding DTMF signal, because the generated DTMF signal will produce a key tone similar to entering the password bit through the keyboard, in order not to be stolen by illegal elements by analyzing the key tone, it is also necessary to convert the password bit into a DTMF signal. Shield the key tone generated by the DTMF signal.

As a preferred embodiment of the present invention, while performing step S104, step S105 may also be performed:

In step S105, a string of random numbers is displayed in the password input box of the display screen.

In the embodiment of the present invention, a string of random numbers displayed in the password input box of the display screen is false information, which has nothing to do with the user password. On the one hand, it is to remind the calling user that the password has been input; The purpose of confusing criminals.

As another preferred embodiment of the present invention, in order to prevent the loss of the mobile terminal used by the calling user, causing criminals to use the call function of the mobile terminal to handle corresponding services, the embodiment of the present invention may also include the steps S106:

In step S106, the password protection function is set, before talking with the called user end or before receiving the password protection item of selection, receive the opening described password protection function of input, open described password protection function; After the end of the call at the end, receive the input to disable the password protection function, and disable the password protection function.

In the embodiment of the present invention, the calling user can set a password protection function in the call setting of the mobile terminal used, and the password protection function means that the calling mobile terminal can read the pre-stored password during the call. Opening the password protection function requires a user password, which is set by the user himself. When the password protection function is turned off, even if someone else gets the mobile terminal used by the calling user, the password stored in advance cannot be called during the call.

It should be noted that step S106 is not executed after step S105, and that enabling the password protection function may be executed before step S101 or S102; disabling the password protection function is executed after step S105. The setting of the password protection function can be performed before step S101, and can also be performed before step S102.

In the embodiment of the present invention, during a call, after the calling user hears the prompt tone for entering the password, he first selects the password protection item corresponding to the password type, reads the password stored in the password protection item, and enters the password in the password protection item. The last bit of the password is added with a password terminator to generate a password bit; then the password bit is processed to generate a DTMF signal corresponding to the password bit, and to shield the generation of a key tone corresponding to the DTMF signal. While reducing the input complexity of passwords required during calls, it also solves the problem of password protection and improves the security of sensitive business information such as telephone banking.
