As shown in fig. 1-2, a digital password control method using a fingerprint chip includes:
establishing a first association mechanism of the fingerprint trigger action and the digital password, so that a digital instruction is input through the fingerprint trigger action;
establishing a second association mechanism of the fingerprint characteristics and/or the fingerprint trigger action and the control instruction, so that the control instruction is input according to the fingerprint characteristics and/or the fingerprint trigger action;
and acquiring a digital instruction and/or a control instruction according to the fingerprint triggering action and/or the fingerprint characteristics, and carrying out corresponding operation.
The invention utilizes the digital password control method of the fingerprint chip, based on the fingerprint chip (namely the fingerprint sensor, including capacitive sensing or optical sensing), through the point contact action and fingerprint characteristic of the fingerprint, realize the signal input of the figure and other operation instructions such as deleting, unblocking, etc., then only use the fingerprint chip, can realize fingerprint characteristic and double-mode unblock of the digital password of the fingerprint lock apparatus, solve when the fingerprint sensor is damaged or the finger fingerprint is subjected to changes such as wearing, etc., causes the fingerprint to discern unsuccessfully, can unblock through the digital password; and meanwhile, the numeric keyboard is liberated, so that the influence of the numeric keyboard on the attractiveness of the fingerprint lock equipment is avoided.
The method is realized by a fingerprint lock or equipment (such as an intelligent mobile terminal and the like) comprising the fingerprint lock, and the method is explained by taking the control of the fingerprint lock as an example:
s1, establishing an authority management mechanism, and identifying and confirming the management authority through fingerprint characteristics;
in this step, an Administrator identity (Administrator account) of the fingerprint lock is set, and the identity is confirmed by entering fingerprints, and generally two identities are set, that is, two fingerprints are entered and respectively associated with two Administrator accounts, so that Administrator setting is completed. After logging in the device (namely the fingerprint lock in the embodiment) through the fingerprint of the administrator, the device has the authority of logging in the fingerprint, logging in the password, and clearing (deleting) the fingerprint and the password.
In this embodiment, in the initial state of the device (or factory settings are restored), when no fingerprint is entered (including administrator fingerprint entry), any fingerprint can be unlocked, and once the fingerprint is entered, the illegal fingerprint cannot be unlocked.
Step S2, a first association mechanism of the fingerprint trigger action and the digital password is established, so that a digital instruction is input through the fingerprint trigger action, wherein:
the fingerprint trigger action is a trigger action which can be sensed by equipment (such as a fingerprint sensor), and the fingerprint trigger action can be a finger touch action, but is not limited to the finger touch action; a digital code is a digital message that contains a 1-8 digit composition. The first association mechanism associates a specified fingerprint trigger action with a number in a one-to-one correspondence, for example, the fingerprint trigger action: pressing with a finger for 1 time, corresponding to an associated number of "1"; fingerprint triggering action: continuously pressing the finger for 2 times, corresponding to the associated digit of '1', wherein the interval of continuous pressing, namely finger pressing, is not more than 2s and is generally less than 1 s; by analogy, other numbers can be associated through the fingerprint triggering action; in order to reduce the setting difficulty of the fingerprint triggering action, the numbers of 0 and 9 are not required to be set, and the password of the equipment is formed by 1-8. The association relation between the fingerprint trigger action and the number is correspondingly stored in a database of the equipment.
Step S3, establishing a second association mechanism of the fingerprint characteristics and/or the fingerprint trigger action and the control instruction, so that the control instruction is input according to the fingerprint characteristics and/or the fingerprint trigger action: wherein:
the control instructions comprise a fingerprint inputting instruction, a password inputting instruction, a fingerprint and password deleting (clearing) instruction, a fingerprint unlocking instruction and a password unlocking instruction; the second association mechanism associates the specified fingerprint features and/or fingerprint trigger actions with the control instructions in a one-to-one correspondence manner to complete configuration; the fingerprint trigger action is added with a time attribute, for example, in the fingerprint trigger action, long-time pressing (such as 5s) is used for inputting a fingerprint instruction, or long-time pressing (such as 10s) is used for inputting a password instruction, and the like; the unlocking can also be directly carried out by identifying the fingerprint characteristics through the fingerprint sensor. And correspondingly storing the fingerprint characteristics and/or the incidence relation between the fingerprint triggering action and the control instruction in a database of the equipment.
S4, according to the fingerprint trigger action and/or fingerprint characteristics, obtaining a digital instruction and/or a control instruction, and carrying out corresponding operation, wherein the operation comprises the following steps:
s41, inputting a fingerprint: acquiring a fingerprint triggering action executed by any fingerprint when an administrator fingerprint or an empty fingerprint is stored, inputting a fingerprint inputting instruction, and entering a fingerprint inputting state; and finishing fingerprint input through fingerprint feature acquisition and identification of preset successful times. The input state of information such as fingerprint trigger action and/or fingerprint characteristics is displayed through the indicator lamp.
In a specific embodiment provided by the invention, the fingerprint of an administrator (or any fingerprint during empty fingerprint storage) is pressed for about 5 seconds (a fingerprint sensor of equipment), and a blue lamp is released after being lightened, so that the fingerprint entering state is indicated; the finger to be set is aligned to the center position of the fingerprint sensor of the equipment and is pressed, if the fingerprint data is successfully acquired, a green light is flashed to indicate that the next data can be recorded, if the data is not recorded or fails, a red light is flashed to indicate that the acquisition is invalid, and 10 times of successful acquisition are needed; after 10 times of completion, the green light is on, indicating that the fingerprint addition is complete. The blue light is normally on throughout the process of entering a fingerprint (indicating a fingerprint entry status), but does not light multiple colors at different times. The pressed finger requires multiple angles for collection, which is beneficial to the expansion of the database and is helpful to the judgment sensitivity! The first fingerprint and the second fingerprint recorded in the embodiment are used as the fingerprint data of the administrator; when the empty fingerprint storage is no fingerprint input, any fingerprint can be used as the fingerprint of the administrator.
S42, inputting a password: acquiring a fingerprint triggering action executed by the fingerprint of an administrator, inputting a 'input digital password' instruction, and entering a state of inputting a digital password; and according to the established first association mechanism, triggering an action through a fingerprint to finish password entry. The input state of the fingerprint trigger action is displayed through the indicator lamp.
Furthermore, recording pause time is preset and is used for collecting fingerprint trigger actions of a plurality of numbers at intervals;
and presetting entry stop time for finishing default digital input.
The fingerprint trigger action input interval between the password numbers is not shorter than the preset input pause time and not longer than the preset input stop time.
In one embodiment of the present invention, the password must be entered before the fingerprint is entered, i.e., the administrator fingerprint configuration is completed. The fingerprint sensor of the device is pressed by the fingerprint of the administrator for about 10 seconds, and the blue light flickers and then is released, so that the password entering state is indicated. In the state of inputting the password, rapidly pressing the fingerprint for several times to show that the number is input (for example, rapidly pressing the fingerprint for 3 times to show that the number is input 3); after the time is paused for about 1 second (namely the preset recording pause time), the green light is turned on for a short time, which indicates that one digit is successfully input and the next digit can be input; after a plurality of numbers are input, if the touch fingerprint is not sensed after the operation is stopped for about 2 seconds (namely the preset recording stop time), the green light is on for indicating that the password setting is successful, and the red light is on for indicating that the password setting is failed.
For example, a finger touches the fingerprint sensor 3 times in quick succession (the interval does not exceed 1s) to represent the number of input 3, and after the finger pauses for about 1 second, the finger presses 5 times in quick succession to represent the number of input 5; then pressing the fingerprint sensor for 8 times in a quick and continuous manner after the praise stops for 1 second, recording the number as 8, stopping pressing the fingerprint after 2 seconds, and finishing the password setting; the resulting numeric code is 358.
The group of passwords is one or a plurality of ordered combinations of the numbers 1-8, and only one group of passwords can be set in the equipment, and the old passwords are directly covered after each setting.
S43, deleting all fingerprints and passwords: acquiring a fingerprint triggering action executed by the administrator fingerprint, inputting a command of deleting all fingerprints and passwords, verifying the fingerprint authority, and executing emptying operation. The input state of the fingerprint trigger action is displayed through the indicator lamp.
In a specific embodiment provided by the invention, the fingerprint sensor of the device is pressed for about 15 seconds by the fingerprint of the administrator until the fingerprint of the administrator is loosened after the red light is lightened, the fingerprint of the administrator is waited to be verified, the verification fails, and the red light flickers; after the verification is passed, the green light is on for a long time, and all fingerprints and passwords are deleted.
S44, fingerprint unlocking: and collecting fingerprint features, comparing and verifying the fingerprint features with the recorded fingerprint features stored in the database, and judging whether to unlock according to a verification result.
After a fingerprint is recorded, when unlocking is carried out, a finger is pressed on a fingerprint sensor, the device detects the finger through the fingerprint sensor and collects fingerprint characteristic data, the collected fingerprint characteristic data is compared with the recorded and stored fingerprint characteristic data, if the comparison is successful (namely the fingerprint is correct), a green light is turned on for about 1 second, and a motor rotates to unlock; if the comparison fails (the fingerprint is incorrect), the red light is turned on for 1 time, and failure is prompted.
S45, password unlocking: and under the password unlocking state, acquiring a digital instruction input by the fingerprint triggering action, carrying out consistency comparison verification on the input digital instruction and the input digital password stored in the database, and judging whether to unlock according to a verification result.
After long pressing of an unregistered fingerprint or an unidentified finger (the unlocking is unsuccessful, and a red light is lighted at the moment) for about 5 seconds, the blue light flickers and then is released, and the unlocking state of the input password is indicated; the password input unlocking is the same as the password input unlocking, and a corresponding digital password is input through a finger touch action; in the password input process, a finger is pressed, the device only detects whether the finger is pressed through a sensor, fingerprint characteristics are not collected and compared, after the password is input, the password is stopped for about 2 seconds, the password comparison is automatically carried out, the comparison is correct, a green light is turned on for about 1 second, and the motor is rotated to unlock; if the input digital code is incorrect, the red light is turned on for 1 time.
The method can realize the dual-mode unlocking function of the fingerprint and the digital password based on the fingerprint chip, and unlock the fingerprint through the digital password when the fingerprint cannot be identified, thereby ensuring double guarantee and improving the use experience of users; in addition, the control method of the invention does not need to arrange digital keys on the equipment, is beneficial to the miniaturization development of electronic equipment, improves the aesthetic property of the equipment, can reduce the additional cost of arranging the digital keys (comprising virtual keys and entity keys) for the fingerprint lock in the prior art, is easy to operate and is suitable for popularization.
