It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a full understanding of the invention, but the invention may be practiced otherwise than as described herein. Limitations of the embodiments.

FIG. 1 shows a flow chart of a fingerprint identification method according to an embodiment of the present invention.

As shown in FIG. 1 , an aspect of the present invention provides a fingerprint identification method, including: Step 102: Collecting at least one first fingerprint by using a first collection module; Step 104, collecting at least one second fingerprint by using a second collection module.

In addition, when the design user is in an unconscious state, it is more difficult to unlock the terminal, because if there is only one acquisition module, only ten experiments are required to pass the fingerprint recognition. However, in the present invention, the acquisition module has two or two. The acquisition module can be set separately, and the two acquisition modules can also perform multiple acquisitions and multiple verifications according to the preset settings. Therefore, unless the user voluntarily unlocks, it is difficult for others to pass the fingerprint identification through experiments. Thereby, the security level of fingerprint recognition when the user is in an unconscious state is improved.

In the above technical solution, preferably, the first collection module is located on the terminal, and the second collection module is located in an external device connectable to the terminal; the multiple fingerprint samples are stored In the terminal and/or in the external device.

In the technical solution, the first collection module is located on the terminal, and the second collection module is located in the external device. Therefore, when the user normally uses the terminal, the second collection module is hidden in the external device, and therefore, when the user is in an unconscious state At the same time, the other party can only use the first acquisition module to semi-unlock the terminal, and cannot use the second acquisition module to completely unlock the terminal. Therefore, even if someone passes the fingerprint recognition on the terminal in the unconscious state of the user, at most, the terminal can perform most simple operations on the terminal, and cannot steal the private information of the user in the terminal, thereby improving the security performance of the terminal.

In the technical solution, the external device is only used to collect the second fingerprint and transmit the collected second fingerprint to the terminal, so that the terminal can control the terminal by comparing the first fingerprint, the second fingerprint, and the pre-stored fingerprint sample. Perform the corresponding preset operation. This solution can reduce the workload of external devices, thereby reducing the performance requirements of external devices, and at the same time, the external devices can be designed to be light and easy to carry.

In the above technical solution, preferably, the second fingerprint is transmitted to the terminal by wire or wirelessly.

In the technical solution, the external device can be directly connected to the terminal, and the second fingerprint collected by the external device can be transmitted to the terminal. Specifically, for example, when the terminal is a portable mobile terminal such as a mobile phone, the earphone hole of the mobile phone can be utilized. That is, a headphone plug can be set on the external device, so that the wired connection between the external device and the terminal can be realized by using the cooperation of the earphone plug and the earphone hole. At the same time, the external device and the terminal can also be connected by using a wireless manner. Specifically, the connection between the external device and the terminal can be realized through various wireless methods such as Bluetooth and WIFI.

In the above multiple technical solutions, when the comparison result is that each of the first fingerprints matches a stored fingerprint sample and each of the second fingerprints matches a stored fingerprint sample, the preset operation To: completely unlock the terminal and enter a private operation mode; when the comparison result is that each of the first fingerprints matches the stored fingerprint samples, but any fingerprint in each of the second fingerprints When the stored fingerprint samples do not match, the preset operation is: semi-unlocking the terminal and entering a normal operation mode; and when the comparison result is any fingerprint and stored in each of the first fingerprints When the fingerprint samples do not match, whether the second fingerprint matches the stored fingerprint samples, the preset operation is: no response to any operation.

In the technical solutions, the user can set the terminal into multiple modes according to actual needs, so that the terminal can start the corresponding mode according to the matching of the input fingerprint and the pre-stored fingerprint. For example, the user can divide the terminal into multiple terminals. The normal operation mode and the private operation mode, so when the first fingerprint input by the user matches the pre-stored fingerprint, but the second fingerprint input by the user does not match the pre-stored fingerprint, only the normal operation mode of the terminal is opened, In the mode, the user can simply operate the terminal, such as listening to songs, setting an alarm clock, and answering a call. When the first fingerprint input by the user matches the pre-stored fingerprint and the second fingerprint input by the user also matches the pre-stored fingerprint, the terminal can open the private operation mode, in which the user can completely operate the terminal, and then the user Some passwords in the terminal can be changed and payment software in the terminal can be used. However, if the first fingerprint input by the user is inconsistent with the pre-stored sample fingerprint, the terminal does not respond to any operation regardless of whether the second fingerprint collected by the second collection module is consistent with the sample fingerprint. The technical solution, by designing multiple fingerprint verification, correspondingly multiple verifications to correspond to multiple modes of the terminal, so that when the user is in an unconscious state, it is more difficult to unlock the terminal, thereby improving the reliability of the fingerprint identification method.

Therefore, even if someone passes the fingerprint recognition on the terminal in the unconscious state of the user, at most, the terminal can perform most simple operations on the terminal, and cannot steal the private information of the user in the terminal, thereby improving the security performance of the terminal. When the user needs to completely unlock the terminal, the terminal only needs to be connected to the external device, so that the terminal can be completely unlocked quickly.
