[0069] First embodiment
[0070] Such as figure 2 As shown, the fingerprint and password combined verification device of the present invention may be a mobile phone 1. The mobile phone 1 at least includes a touch screen 10, a fingerprint recognition module 11, a touch recognition module 12, a keyboard layout module 13, a password processing module 14, and a fingerprint processing module 15. And storage module 16. The touch screen 10 has a fingerprint recognition function. The fingerprint identification module 11 is configured to perform fingerprint identification on a user's finger touching the touch screen. The touch recognition module 12 is configured to perform touch recognition on a user's finger touching the touch screen. The keyboard layout module 13 is configured to lay out virtual keys of the input keyboard on the touch screen. The input keyboard is displayed in a matrix form, but it is not limited to this, and can also be arranged in a honeycomb arrangement, a tree a...

[0083] Second embodiment
[0084] Such as Figure 8 to Figure 9 As shown, the second embodiment is a modified example on the basis of the first embodiment. In this embodiment, the input keyboard displayed on the touch screen 10 of the mobile phone 1 is a randomly arranged input keyboard, and the layout of the input keyboard is displayed every time. It is inconsistent with the input keyboard of the previous layout. This makes the position of the virtual button change every time a password is required. Compared with the conventional input keyboard, the conventional input keyboard has a fixed layout, and the fingerprint corresponding to the password key will remain in a fixed position. Others can know which digital key the fingerprint corresponds to by observing the position of the fingerprint. The second embodiment can avoid this problem.
[0085] Similarly, refer to the settings of the password corresponding to the fingerprint in the first embodiment: the pre-stored password is "1...
Example
[0091] The third embodiment
[0092] Such as Figure 10 to 14 As shown, the fingerprint and password combined verification device of the present invention may be a mobile phone 2. Running the fingerprint and password combined verification method of the present invention on the mobile phone 2 includes the following steps:
[0093] S201: The pre-stored passwords are "1, 2, 3", and three user fingerprints (fingerprint Y1 of the user's right thumb, fingerprint Y2 of the user's right index finger, and fingerprint Y3 of the user's right middle finger) are registered, and each password is established with at least The correspondence of a user fingerprint is as follows:
[0094] The password "1" corresponds to the fingerprint Y3 of the user's right middle finger;
[0095] The password "2" corresponds to the fingerprint Y2 of the user's right index finger;
[0096] The password "3" corresponds to the fingerprint Y1 of the user's right thumb. (In actual use, it is not limited to this. Users can...
