Fig. 4 has shown the flowchart of the mobile terminal fingerprint password setting that the embodiment of the present invention provides, as shown in Fig. 4, comprises the following steps:

Step S401: Support users to customize the keyboard type for fingerprint input according to their own habits and preferences;

Such as computer physical keyboards, input method 26-key keyboards, alphabets, numeric keyboards, etc., also support self-design and typesetting, and you can make specific keyboards according to your commonly used letters, numbers, and symbols.

Step S402: the user selects a certain type of keyboard;

The example is a computer physical keyboard, with horizontal rows as a sequence, a total of 4 sequences: number row, "q" row, "a" row, and "z" row.

Step S403: the user enters the fingerprint to realize the corresponding sequence of different fingerprints;

Example: The number row is the fingerprint of the right index finger, the "q" row is the right middle finger fingerprint, the "a" row is the left index finger, and the "z" row is the left middle finger. In practice, the user can enter the corresponding sequence according to his/her own habits (if all these 4 sequences are entered into the right index finger, then these 4 sequences will appear in order from top to bottom when it is turned on). That is to say, the user can define a sequence of numbers (letters, symbols) represented by the finger on the screen after a long press of a certain finger. 9-0 digital line", the middle finger represents the "q line", the ring finger represents the "a line", the little finger represents the "z line"), the keyboard of the mobile phone input method (such as the index finger represents the "digital panel", the middle finger represents the "q line" , ring finger for "row a", little finger for "row z"), or even sequential columns of the alphabet (such as index finger for "letter a-g", middle finger for "letter h-n", ring finger for "letter o-t", little finger for "letter u-z") and so on. At the same time, users are supported to customize the sequence represented by each finger according to personal habits and for safety considerations (for example, when using a computer keyboard, the user can set the index finger to represent "z row"), and even each finger can represent a sequence of multiple lines (such as using When using a computer keyboard, the user can set the index finger to represent the "z row" and the "number row").

Step S404: slide the finger to determine the required number (letter, symbol);

After calling up a certain sequence, the user taps the desired number (letter, symbol) by sliding his finger on the fingerprint sensor. For example, press and hold the index finger to call out a certain sequence, and then slide the index finger, then the corresponding numbers (letters, symbols) on the screen will also slide with the index finger for the user to choose. symbol), you can confirm by tapping your index finger. Then you can continue to select the desired number (letter, symbol) in the sequence, or change another finger and long press to call up a new sequence, and then select a new number (letter, symbol), which also supports fingerprints for distinguishing left and right hands.

Step S405: Complete password setting.

After all password numbers (letters, symbols) are input, you can use but not limited to long press or double click on the fingerprint sensor with three fingers, or long press with your thumb, etc. Through similar gestures, the password entry process is completed. Alternatively, tap the "Done" button directly on the screen.

The entry in step S403 uses the collection module 302 , the collection module 302 mentioned here is, for example, a fingerprint identification sensor, and the structure and principles of the fingerprint sensor are already known in the art and will not be described in detail.

Fig. 5 has shown the flow chart of the mobile terminal fingerprint password input that the embodiment of the present invention provides, as shown in Fig. 5, comprises the following steps:

Step S501: When inputting content, use a finger to press and hold on the fingerprint sensor to call out the corresponding set sequence, and slide the finger on the sensor to select the corresponding number (letter, symbol);

According to the set password (for example, the set password is scc31, the input "s-index finger", "c-middle finger", "3-ring finger", "1-little finger"), the user sequentially uses the corresponding finger fingerprint verification— - index finger, middle finger, middle finger, ring finger, little finger. Pay attention to the difference between the fingers of the left and right hands. Specifically:

Step1 Press and hold the left index finger -> pop up line a -> slide the left index finger to reach s, click OK;

Step2 Press and hold the left middle finger -> pop up the z line -> slide the left middle finger to reach c, click OK;

Step3 Repeat step2, that is, press and hold the left middle finger -> pop up the z line -> slide the left middle finger to reach c, click OK;

Step4 Press and hold the right index finger -> pop up the number line -> slide the right index finger to reach 3, click OK;

Step5 Press and hold the right index finger -> pop up the number line -> slide the right index finger to reach 1, click OK. That is to say, the input is completed.

Step S502: After all numbers (letters, symbols) are input, the fingerprint password is saved and recorded by the storage module 303 .

Step S503: When a password needs to be input, directly enter it in sequence according to the preset sequence of fingerprints, and if they are consistent, the authentication is successful (authentication module 404).

In the method exemplified in step S501 above, the left index finger, left middle finger, left middle finger, right index finger, and right index finger are sequentially placed in the collection module 301 . The processes of step S501 and step S502 can also be used again for fingerprint input.

The present invention avoids the method of directly selecting letters (numbers or symbols) on the input method keyboard, which is easy to disclose secrets. There may be many scenes requiring higher security factors such as inputting passwords, but the present invention is not limited. After defining the password, when inputting the password, the user can either directly use the fingerprint to decrypt it, or use the fingerprint to input the password again, both of which are supported by the present invention, which is why the authentication module 404 in the present invention is different from other authentication modules in the field point of difference. The authentication module 404 is not necessary, and is not limited to matching only for password authentication. It can be disassembled or combined, and the order of some processes can be exchanged and repeated, and it cannot be limited by this.

In summary, the present invention has the following technical effects:

The present invention uses different fingerprints to set different numbers (letters, symbols), which improves the security of the password.

Although the present invention has been described in detail above, the present invention is not limited thereto, and various modifications can be made by those skilled in the art based on the principle of the present invention. Therefore, any modifications made according to the principles of the present invention should be understood as falling within the protection scope of the present invention.
