detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a schematic flow chart of a recording method in an embodiment of the present invention. The flow of the method can be implemented by a recording device. The recording device can be a user terminal or a software program running on the user terminal. The user terminal can include a mobile phone, Notebook computers, tablet computers, vehicle-mounted computers, POS (PointOfSales, point of sale) machines, etc. As shown in the figure, the method at least includes:

Step S101, receiving a recording start instruction input by a user.

Specifically, the recording start command is a functional command that can start the recording application program of the terminal and directly collect sound information for recording. Specifically, it can be pressing the recording button, or sliding the unlock button to The sliding operation of the recording application can also be a gesture touch operation on the terminal when the terminal is in a black screen standby state, and the like. The input method of the recording start instruction may be the initial setting of the terminal, or may be preset by the user.

Furthermore, the recording start instruction can be an instruction directly input by the user on the terminal, or a remote control instruction input by the user through other terminal equipment, for example, the user uses infrared remote sensing equipment such as bluetooth or remote control of the smart bracelet The recording start command input to the terminal.

When the terminal receives the recording start command input by the user, it can compare it with the recording start command preset by the user or the terminal. If the two match, it will execute the recording start command. Otherwise, the terminal can prompt the user through a pop-up prompt box The command is wrong, let the user input the command again. Furthermore, a threshold value of times can also be set, and if the number of wrong user command input exceeds the preset threshold value, the user will be reminded to start the recording in other ways or go to the setting page to reset the command to start the recording.

Step S102, acquiring the activation verification information input by the user.

Specifically, the opening verification information can be one, more or all of information such as digital password information, biometric information, sliding gesture information, and touch operation information, and is used to confirm whether the recording opening instruction input by the user can continue. Authentication information performed. The type of information for enabling the verification information may be pre-selected by the user, or preset by the terminal.

In a specific implementation, after the terminal receives the recording start instruction input by the user, a prompt box may pop up to prompt the user to input the start verification information. If the verification information is only one of digital password information, biometric information, sliding gesture information, touch operation information and other information, such as digital password information, the terminal can directly prompt the user to enter the digital password information; if the verification information is not only One of the above information, the terminal may first prompt the user to select the type of information, and then input the corresponding activation verification information according to the type of information.

Further, it is also possible to set priorities for the types of information that enable the verification information, and use the information type with the highest priority as the first choice to enable the verification information. Sequentially switch the types of verification information until the verification is successful or all information types have been switched. For example, if the user sets the order of priority digital password information, biometric information, and sliding gesture information as the activation verification information, the terminal can first prompt the user to enter the digital password information, and if the user clicks Forgot Password, the terminal can remind the user to enter the biometric information, if the verification of the user's biometric information fails, the terminal will remind the user to input the sliding gesture information.

Step S103, detecting whether the opening verification information input by the user matches the preset opening verification information.

Specifically, the activation verification information is information corresponding to the activation verification information and used to verify whether the activation verification information is correct, that is to say, it is information authorized to enable the recording application. After the terminal obtains the activation verification information input by the user, it may compare it with the activation verification information, and judge whether they match according to the comparison result. Further, a similarity threshold can be set, and if the similarity after comparison between the opening verification information and the preset opening verification information is greater than the set similarity threshold, it means that the opening verification information matches the preset opening verification information, If the similarity is less than the set similarity threshold, it means that the activation verification information does not match the preset activation verification information.

For example, if the verification information is a swipe gesture, the terminal can compare the swipe trajectory corresponding to the swipe gesture input by the user with the swipe trajectory corresponding to the preset swipe verification gesture to verify whether it matches, and set the trajectory similarity threshold to 85%, if the similarity between the sliding trajectory corresponding to the sliding gesture input by the user and the sliding trajectory corresponding to the preset sliding verification gesture is less than 85%, it means that the sliding gesture input by the user matches the preset sliding verification gesture, otherwise The description matches.

Optionally, before detecting whether the opening verification information input by the user matches the preset opening verification information, the method may further include: acquiring and saving the opening verification information input by the user.

Specifically, before using the activation verification information to detect the matching of the activation verification information, the terminal may first obtain and save the activation verification information set by the user as a reference template for matching detection. Consistent with the activation verification information, the activation verification information can also be one, more or all of digital password information, biometric information, sliding gesture information, touch operation information, etc., and the user can enable it in the setting interface. Verify information to select, enter and save.

Step S104, if the activation verification information input by the user matches the preset activation verification information, start the recording program corresponding to the recording activation instruction and record the input voice information.

Specifically, if it is detected in step S103 that the activation verification information input by the user matches the preset activation verification information, the terminal can start the recording program corresponding to the recording activation command, and the recording program directly starts to record the sound of the input terminal .

A recording program, and the recording program directly starts to record the sound of the input terminal.

Step S206, if it is detected that the activation verification information input by the user does not match the preset activation verification information, rejecting the recording activation instruction.

Specifically, if it is detected in step S204 that the activation verification information input by the user does not match the preset activation verification information, that is, the fingerprint information input by the user does not match the preset fingerprint verification information, the terminal may refuse to perform recording activation. instruction.
