[0070] Such as figure 2 As shown, the fingerprint and password combined verification device of the present invention can be a mobile phone 1, and 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 the 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 layout the virtual keys of the input keyboard on the touch screen. The input keyboards are displayed in a matrix form, but not limited thereto, and may also be arranged in a honeycomb arrangement, a tree arrangement, and the...

[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 keyboards displayed on the touch screen 10 of the mobile phone 1 are input keyboards arranged randomly, and the input keyboards of the display layout are arranged each time. Inconsistent with the input keyboard of the previous layout. So that every time a password needs to be input, the position of the virtual key will change. Compared with the conventional input keyboard, the layout of the conventional input keyboard is fixed, and the fingerprint corresponding to the password key will remain in a fixed position. Others can know which number key the fingerprint corresponds to by observing the position of the fingerprint. However, the second embodiment can avoid this problem.

[0085] Similarly, refer to the setting of the password corresponding to the fingerprint in the first embodiment: the pre-stored password is "1, ...

[0092] Such as Figures 10 to 14 As shown, the fingerprint and password combined verification device of the present invention can be a mobile phone 2, and the fingerprint and password combined verification method of the present invention is run on the mobile phone 2, comprising the following steps:

[0093] S201: The pre-stored passwords are "1, 2, 3", and register three user fingerprints (the fingerprint Y1 of the user's right thumb, the fingerprint Y2 of the user's right index finger, and the fingerprint Y3 of the user's right middle finger), and establish each password 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. (It is not limited to this in actual use, users can define thei...

Abstract

The invention discloses a fingerprint and password combined type verification method and a device thereof. The fingerprint and password combined type verification method and the device thereof are used in an electronic device with a touch screen, and the touch screen has the fingerprint recognition function and the touch recognition function at the same time. The method includes the following steps that an input keyboard which is provided with a plurality of virtual keys is displayed, and if an input password is the same as a pre-stored password and each fingerprint for operating the virtual keys is matched with a corresponding pre-stored user fingerprint, verification is successful. By means of the fingerprint and password combined type verification method and the device thereof, cracking verification difficulty is greatly increased, and privacy protection to the electronic device is improved; the practicability of the method is almost the same as the practicability in an existing mode, under the condition that user difficulty is not increased, the password cannot be cracked by others easily, and hence the confidentiality which is far higher than that of an existing verification mode is achieved.

Description

technical field [0001] The invention relates to the field of password verification, in particular to a fingerprint and password combined verification method and a device for realizing the fingerprint and password combined verification method. Background technique [0002] With the wide application of portable terminals in people's daily life, the functions of the current portable terminals are becoming more and more powerful, and such diversified functions are convenient for users. However, while the portable terminal provides more convenience for the user, it carries too much private information. If the portable terminal is lost or stolen, the information is easily leaked because there is no relevant protection. cause inconvenience to users. Therefore, it is very necessary to do some security settings on the portable terminal. [0003] The security function of a traditional portable terminal with a touch screen is nothing more than setting software functions such as a key...
