Combined fingerprint password system and operation method

Abstract

The invention discloses a combined fingerprint password system and an operation method. The combined fingerprint password system comprises a display switch, a touch screen display, a fingerprint inputmodule, an encryption mode detection module, a memory module, a check module, an execution module, a lock and an error counter; when the system is used for the first time, a fingerprint input function is selected on the touch screen display, an encryption mode is selected to be a serial mode, a parallel mode or a composite mode, and fingerprints are input according to system prompts; during unlocking, an unlocking function is selected on the touch display screen, a fingerprint password is input according to the encryption mode, the check module checks the fingerprint password, if the fingerprint password is wrong, inputting the fingerprint password again and feeding back error information to the error counter at the same time, and if the input fingerprint password is correct, the execution module drives the lock to be unlocked; according to the invention, the safety performance is improved by combining the diversity and complexity of the key password and the uniqueness of the fingerprint password, and meanwhile, the defect that the password is easy to forget by a key password lock is reduced to a certain extent, so that the risk that the password is cracked by a person by adoptinga single fingerprint is reduced.

Description

technical field [0001] The present invention relates to the field of fingerprint encryption, in particular to a combined fingerprint encryption system and operation method Background technique [0002] The security protection measures used today are mainly traditional mechanical locks, key combination locks and fingerprint combination locks. With the development of science and technology, fingerprint combination locks are more and more popular among the public. In addition to the appearance and cost-effectiveness, many families are willing to use fingerprint locks. You don’t need to bring a key when you go out, and you can unlock and enter the door by simply reaching out to enter your fingerprint. This solves a big problem for people who have forgotten their keys or passwords for a long time. With the development of science and technology, fingerprint unlocking has gradually become popular, whether it is mobile phones, anti-theft doors or safes, there are a lot of uses. ...

Problems solved by technology

[0003] However, whether it is unlocked by pressing a button, such as a bank counter or other occasions that require a password, the security performance is not high, because the operation of the button may be captured or remembered, or it is unlocked in the form of a fingerprint. Unique, but once a person's fingerprint information is adopted or stolen, his property and information security will not be guaranteed, and there are certain risks and shortcomings

There is more or less singleness in the storage of things in the traditional encryption method, so no matter whether it is a mechanical method or a fingerprint method, it is possible that relevant unlocking evidence will be collected by interested people and cause property loss to the lock owner.
